overclocking

[mental turret]

its a good guide so far i'd say

S1G section is still naked for some reason

https://community.hwbot.org/topic/186190-samsung-ddr3-g-die/ plenty of info in this thread alone

could've also asked several mem oc people in HWBot too who've use the IC a lot

[finite frigate]

48,000MB/s max theoretical bandwidth

(dual channel)

quad would do it

[short blade]

the wording sounds like he wants to use his own data? not sure

[mental turret]

yea that was my assumption

https://www.ebay.com/itm/275858499800? @ancient bridge

could be garbage, could be competitive

only one way to find out

(buy it)

[steady lance]

Is it bad if tRP isn't equal to tRCD?

[steady lance]

Can I have tRAS set below tRCD + tRP?

[short blade]

no, as long as it’s stable it’s good

[short blade]

yes, like I said like 4 times there are no “rules” for the composition of tRAS

most of the rules people like to state for timings are… imaginary

such as “tRAS = tRCD + tRP” or “tRC = tRFC / 8” or whatever

people have come up with a lot of crap lol idk

[steel spade]

i see no issues

[short blade]

the only real rules I’m aware of are “tFAW >= tRRD_S *4”, “tRC = tRP + tRAS”, “tWRRD_dg = tWTR_L + tCWL + 4”, “tWRRD_sg = tWTR_S + tCWL + 4”, “tWRPRE = tWR + tCWL + 4”

and you only need to concern yourself with the first one

tRAS is irrelevant because AMD literally ignores it and just uses whatever you set for tRP and tRC

the other rules are intel exclusive

if you see any “rule” besides “tFAW >= tRRD_S * 4” please just ignore it

it is nonsense

@steady lance

I mean I guess you can say every _L timing >= the respective _S timing but that’s just kind of obvious and doesn’t need to be said

“tWR = tRTP * 2” is a very commonly stated rule that even shows up in the integralfx ddr4 guide but is also completely false

[steady lance]

What's the hard limit for tRC?

I keep having to clear CMOS....

[short blade]

varies by IC

and frequency

[steady lance]

Started at 44 and I've tried up to 48.

[short blade]

my rev. e could boot with tRC 51 at 3800 but wasn’t stable until 53

my b-die happily did tRC 36 at 4133

[steady lance]

..... Next DDR4 ram kit I buy is gonna be B-day from someone off eBay.

[short blade]

on a lower tier IC like S8D at 3933 I’d expect tRC to have to run closer to 60

I’d try starting with 68 and dropping by 4 until you can’t POST

[short blade]

don’t bother, just upgrade to ddr5 along with your next cpu

[steady lance]

64 is the default and works so I will try 60 then.

[steady lance]

I will.

Welp tRC 60 failed....

Guess I will try 62.

If that fails then I guess I gotta run the default of 64.

[short blade]

it’s not worth spending money on b-die for practical reasons, but you can buy it if you specifically want to play with b-die

just don’t think of it as a serious upgrade

[steady lance]

I want B-die for the fun I get from OC.

[short blade]

it’s like upgrading from a 3070 to a 3070ti lol

except a bit more fun

[steady lance]

xD I have spent around 23 hours on this ram by this point.

[short blade]

sure, that’s a fine reason to buy it
just wanted to say don’t get caught up in thinking that it’s actually a game changer for your daily usage

tuned lower tier ICs will be pretty much indistinguishable in daily usage from tuned b-die

the difference might even be measurable… but if you turn off the fps counter? you’re not going to notice the difference

[steady lance]

S8D is mid to upper-mid tier if I understood right?

[short blade]

most performance does not come from the primary timings anyways

it depends on context I guess

in the context of what you can buy today (modern-ish ddr4) it’s low-mid I suppose

[steady lance]

Is CL16-21-21-17-64 at 3933 decent?

[short blade]

in the context of all ddr4 you could call it high-mid

[steady lance]

I give up on tuning tRC.

[short blade]

that’s not bad

[steady lance]

1.56v

[short blade]

tRC 64 isn’t unreasonable

now I wonder if you could do 4000 if you loosened tRC

[steady lance]

I am board limited or CPU limited at 4000.

[short blade]

4000 with tRC 68

[steady lance]

What does tRC do?

[short blade]

tRC is another timing that needs to be loosened as you go higher frequency

so if 64 is the lowest you can boot 3933

and 4000 was unstable with tRC 64

there’s a chance you could go higher freq by running looser tRC than 64

not saying it’s guaranteed, but hey it’s worth a shot

there’s basically 0% chance you are cpu limited at 3933

[steady lance]

Uhh f it why not.

[short blade]

board is possible

[steady lance]

What should I loosen tRC to?

68?

Wait will I need to loosen everything else to make 4k work?

Upped voltage a bit to 1.58 to see if it helps.

[short blade]

yeah, I’d save the current profile and then go back to all auto timings except primaries for 4000 testing

[steady lance]

Well this happen with tRC at 72

And 1.56v

Is 4000 even worth the difference?

[steady lance]

Thoughts on what settings would cause this?

[steady lance]

Uhhh I reset back to 3933 and tRC 64 and I still have this?

[steady lance]

Please help!

Fixed!!!

PHEWWWW

Just needed to refresh the background

[short blade]

I’m in class lol

[short blade]

visual artifacts?

you’re not using the igpu right?

unstable RAM should only cause visual artifacts on a display connected to igpu

since igpu uses system ram as display buffer

I have 2 monitors connected to igpu and 2 connected to dgpu, so sometimes I’ve had unstable ram cause artifacting on 2 out of 4 monitors

[steady lance]

iGPU is off.

Also is there another name for tREFI?

[short blade]

no, you just don’t get tREFI control on AM4

[steady lance]

Oh.

[short blade]

so don’t worry about it

it’s kind of weird

AM4 you can’t control tREFI
AM5 you can control tREFI but in exchange you lose control of tCWL

[short blade]

very strange then

[short blade]

needing tRC 72 for 4000 is kind of surprising if 64 was stable at 3933

but it's probably worth it if stable

tbh, try tossing tRC at 100 and see if you can gain any more frequency lol

I've seen tRC auto as high as 104 before

you won't want to actually run it that high later on but at least you can eliminate it as a factor while searching for higher freq now

and if the search isn't fruitful at least you have a profile to fall back on now

[steady lance]

Honestly I'm gonna settle for 3933 for tonight and try tuning it more at a later date.

[short blade]

sure

[steady lance]

I have been at this for 11hrs straight.

[steady lance]

NVM I forgot to turn it off when resetting CMOS.

[short blade]

still, it shouldn't cause artifacts if the display isn't connected to the igpu

like I said, only 2 out of my 4 monitors ever artifact from unstable ram even though my igpu is on all the time

[steady lance]

Hmmm odd indeed.

[short blade]

but definitely remember to disable your igpu every time you clear cmos, it actually makes a major impact on how high you can run fclk

iirc gary needed the same vsoc for 2000 fclk + enabled igpu vs 2300 fclk + disabled igpu

[steady lance]

I see.

Also I saw something weird.

When I looked like the SP-Info of my ram in Bios it said 2133 FCLK 4000MHz.

Any thoughts?

[short blade]

I think you misread it

it's probably reporting 2133MHz as the base speed defined on the SPD

SPD would never report anything related to FCLK, in fact SPD is not aware of the existence of FCLK

after all, it's compatible with intel which doesn't have such a thing

[steady lance]

Oh okay.

[short blade]

just don't bother with the SPD info, you won't learn anything new from it

SPD contains the base spec and the XMP profile

it may report the manufacturer of the ICs

you already know all of that

[steady lance]

It did say Samsung xD.

my ram tune

[short blade]

good progress so far

I'd encourage you to check out the ddr4 guide I posted earlier

it's better than the integralfx ddr4 guide

@mental turret @ancient bridge you'd be so proud of my phone right now

it just autocorrected ddr4 to ddr3

[ancient bridge]

As it should

[short blade]

@steady lance did you try raising VDDP while you were trying 4000+?

[steady lance]

It is already set to +0.240

From a default of 0.850

[short blade]

wasn't default 0.75?

so +0.24 wouuld be 0.99 total

i remember you said 0.850 in zentimings was including an offset of +0.100

[steady lance]

I thought it was.

But no matter how I changed the offset it still said 0.850 in ZenTimings

So I think 0.850 is the base.

[mental turret]

good.

https://tenor.com/view/hollup-hold-up-hollup-let-him-cook-hold-up-let-him-cook-let-him-cook-gif-27589255

[short blade]

...cursed

gigabyte bios 💀

see if there's a VDDP setting in the AMD overclocking menu under advanced tab

rather than the main OC tab

maybe that one will be more helpful

[sudden torrent]

At least that one won't be an offset

[mental turret]

My memory is doing the overclocking

Nevermind

[mental turret]

@short blade 48.9GB/s write
Quad 2800C9-12-13-18 loose terts

[sudden torrent]

Bro I get more than that

[mental turret]

with?

[mental turret]

it doesnt say write speed

[sudden torrent]

Oh right

Trial

[mental turret]

It's probably still a bit faster though

[sudden torrent]

Dang it now I'm curious how high I can get my 4 sticks of b-die to go when desynced

I'd wager 4400 c16 at least

... I'll be back in a couple hours

[mental turret]

lol

[proven canopy]

You can run mem tests only if you right click start benchmark

[sudden torrent]

Yolo?

[mental turret]

do it

bdie doesnt know death

[sudden torrent]

Ok 4 sticks doesn't want to do 4400

[short blade]

what board are you on?

i think i hit a board limit while i was trying to push my rev. e for freq

[sudden torrent]

I kinda figured since I found out long ago my adata sticks didn't like anything above 1.55v

[short blade]

4800 on b550 steel legend

can't be certain if it was board limit though

[short blade]

these are some crazy voltages

[sudden torrent]

Same results on 2 different MSI boards, X470 Gaming Plus and X570 Gaming Edge

[short blade]

1.7v for 3600c14 💀

[sudden torrent]

Yeah they can't know that you're on b-die so they have to do presets that more than one die can do

I'm honestly amazed that's even a feature

Since you can insta kill some sticks with it

No to 4200 also on 4 sticks, sadge

I already knew one of my kits was pathetic but not that much

[mental turret]

Why are you running 4 for that

[sudden torrent]

Curiosity

Ok pulling the adata kit

The vipers are binned 4400 so I expect a lot more

[sudden torrent]

Turns out those presets change a lot more than primary and voltage. It sets all the subs and terts too.

[short blade]

interesting

[short blade]

i feel like this is more reason to stay much more conservative lol

like 1.35V

[short blade]

sad, this could actually be a useful tool for casual users if they used more sensible presets

[sudden torrent]

At least you have to enable "expert" mode to even see those presets so there's less chance of accidental rapid deconstruction

Alright 4533 seems to be the limit for the viper sticks

Which is still higher than the 4200 the adata ones capped at

[mental turret]

Accidental Rapid Deconstruction™️

https://tenor.com/view/the-voices-cat-mad-going-insane-going-crazy-gif-24274574

THE VOICES ARE TELLING ME TO DAILY 2.4V

[sudden torrent]

Omfg that penalty running desync is killer

The most I had patience for was 4466 16-16-16-16-34 with tuned subs

And I still couldn't beat my best ycruncher result

It's on my hwbot if you're curious

[steady lance]

what cpu are you pairing those speeds with?

[sudden torrent]

What do you mean by pairing

I'm just setting it in bios

Or do you mean what CPU? 5800X

[steady lance]

Thought that non Monolithic AM4 cpus disliked freq beyond 4000?

[sudden torrent]

That's correct. This is an experiment. I wanted to see where the limit would be for my system so I intentionally ran the fclk desynchronized from mclk.

Even 4000 is a stretch tbh

I'm currently testing at 4000 synced so I can see the impact the WHEA errors have

[steady lance]

ahh okay.

By the way, what are my chances of getting a 5950x to work on a B550M DS3H?

[sudden torrent]

Undervolt it and it'll work ok, as long as you have a fan on the VRM for all core loads

[steady lance]

You mean like blowing on it? Or just having lots of air pulled by it count?

I got a 140mm FC2 pulling air pretty close to the vrms.

[sudden torrent]

Directly blowing on it

[steady lance]

I see.

If I were to buy another motherboard, what would you say would be able to handle a 5950x without going over say like $200?

Cause I've been looking around Ebay and I might be able to get a 5950x for about 300 before shipping.

[sudden torrent]

Were you doing all core loads

[steady lance]

Poking around to scout future chips for a server.

[steady lance]

Blender, and World Painter are my main all core workloads.

I also use Davinci Resolve but that's more GPU bound I think.

is this B-Die?

[sudden torrent]

Yes

[steady lance]

Samsung 16GB B-die correct?

What's the best die for overclocking on DDR4 out of curiosity?

[sudden torrent]

That'll be dual rank 8Gb (16GB total)

B-die is best on Ryzen, rev.e is best on Intel (out of the common ones)

[steady lance]

This ram kit is quite tempting if it's still available in a week or so.

$81 for 2x16GB 4400cl17 xmp.

[sudden torrent]

Oh that's actually pretty good

[steady lance]

at 1.5v

Description says he's had active cooling on it the whole time he has had it and has only been used for a year.

and it happens to be the royal ram which I really like so mhmmm.

Quite tempting.

[sudden torrent]

Not like you could kill b-die if you tried

[steady lance]

really?

So I can shove 10v down it?

[sudden torrent]

But the royal heat spreader isn't great

[steady lance]

Worse then the G.Skill ones?

[sudden torrent]

Most boards hard cap you at 1.8v

[steady lance]

Unfortunately my board does that

[sudden torrent]

Yes because RGB and plastics

[steady lance]

Mhmmm, I see.

Currently do you think it's the cpu or board limiting me from running 4000mhz stable?

[sudden torrent]

Could be either or the combination of the two

[steady lance]

And I am guessing it's highly unlikely I will get 4400 stable on a 5950x?

assuming I buy one that is.

[sudden torrent]

Yeah that'll never happen

If you get 4000 stable you're already a unicorn with that chip

[steady lance]

Ooof.

Is 5950x also cas sensitive?

[sudden torrent]

As much as any other CPU

(ddr4 ones that is)

[sudden torrent]

Let me sing you the song of my people

[steady lance]

Why is the mini fan just dangling....

[sudden torrent]

Because it likes to swing on it's swing I set up

[zenith palm]

Dust yo pc smh

[sudden torrent]

My wife misplaced my duster

[ancient bridge]

Atleast wipe it down 😭

[mental turret]

I have a recommendation

replace your ram heatsinks and bootleg hanging fan with these https://www.ebay.com/itm/304865364656

[finite frigate]

other way

bdie is a lot easier to clock and tune on intel than it is ruzen

[proven canopy]

B-die is best on pretty much everything. But m8e or m16b would be my pick for high capacity

[sudden torrent]

You can't beat the tight timings on b-die, and ryzen loves timings because it doesn't clock nearly as high

Rev.e on the other hand is very good at clocking extremely high, so it's good on Intel

[humble jay]

B die clocks just as high

[short blade]

I think rev. e has a chance at being better on the weaker memory controllers of ryzen 1000/2000

but b-die is better on anything with a decent memory controller

intel 8th-13th, ryzen 3000-5000

not sure about intel 6th-7th

I only used some midrange z170 boards that were probably more limiting than the 7700K IMC

I remember reading about b-die not being able to clock very well on zen/zen+

but yeah the difference in achievable timings between b-die and rev. e are immense

and b-die definitely clocks high enough to reach the practical limits of any ddr4 imc

[sudden torrent]

Nothing clocked well on those, you were lucky to get 3200 on zen+

[short blade]

yeah but you tended to get better results from rev. e being lighter on the imc

[sudden torrent]

It forced fclk=mclk so it would get unstable fast

[short blade]

did I tell you that the 1500x you sent me ran 3533 stable with S8C?

was very surprised by that

[sudden torrent]

Jfc

That is surprising

Those gens were made for c die

[steady lance]

Does JFC stand for Jesus F------ Christ?

[sudden torrent]

Yes

[steady lance]

Gotcha.

What would be a good upgrade on my system within say around $300?

R7-5700G
B550M DS3H
lT720
RTX 3070
2x16gb DDR4 3933@cl16

Would like to get more frames in games like Halo and modded MC. I am getting around 80fps on modded MC currently which feels very choppy.

[rancid seal]

uhhh

literally nothing.

[sudden torrent]

Yeah even the 4060 or 7600 when they come out around $300 aren't an upgrade

[steady lance]

Really?

Ooof.

[steady lance]

If I can get a 5950x as a upgrade for my processor and stick a fan on my VRMs will that be a decent upgrade?

[sudden torrent]

It would be good for multicore loads

[steady lance]

Would it also offer a decent single core boost?

MC at least in the older versions if I remember right, loves high frequencies. Pretty sure, MC prefers more cores now in newer versions.

[rancid seal]

No

[steady lance]

Isn't a 4.9 (with oc probably 5.1) GHz a decent pump from my 4.6ghz?

[ancient bridge]

You're likely not hitting 5.1ghz

I could be wrong tho

[sudden torrent]

You'd need sub-ambient cooling for 5.1 all core

But 5.1 single core boost is possible, my 5800X can do that

[ancient bridge]

I think he meant single core

My 5900x doesnt like to boost higher than the 4.9ghz area in game and or single core

Thats with +200 pbo

[sudden torrent]

I daily 5.05 boost, I can do 5.15 with bclk

On a giant AIO

[ancient bridge]

How tf

Why doesn't mine go higher 💀

[sudden torrent]

I have a god tier chip apparently

[ancient bridge]

Unless there's a way to get it to go further than +200 pbo

[sudden torrent]

I've been offered a 5900X in exchange for it lol

[ancient bridge]

Damn lol

I feel like mine could do more it just doesn't...

[sudden torrent]

Yeah it's still at +200 but if I do bclk 102 it gets another 100MHz

[ancient bridge]

I want to try this now 💀

Usb drop out yay?

[sudden torrent]

Take out your sata drives first

[ancient bridge]

Oh?

Ok

[sudden torrent]

They might spontaneously decide to unalive

[ancient bridge]

LMAO

Well then

It's not worth the +100💀

[sudden torrent]

And underclock your gpu too to be safe, and make sure it applies on boot because bclk affects the pcie slots too

[ancient bridge]

Yeah nvm I'm good

Bclk is alot different on ryzen huh

[sudden torrent]

You want that 100 you gotta work for it lol

[ancient bridge]

Wish pbo just let you go further

[proven canopy]

Do you know the date code by chance?

What does stock vid show in bios? Forget if I already asked

[sudden torrent]

Uhh, idk the date code and I don't have any more good paste (just mid stuff I'd use on X79) so I don't really want to look right now

Let me see if my bios will even tell me core vids

I think this is all I'll get for that

At least this has reminded me I need to get some MX6

[steady lance]

seriously?

Thought +100-200mhz was a pretty reasonable OC considering I could do 4.8ghz on my 5700G though I suppose the difference in CPU architectures would make a big difference?

[sudden torrent]

For 5.1 all core yes, single core boost 5.1 is possible on AIO. The 5950X is already pushed pretty hard so there's no promises you can do +100 let alone +200.

[steady lance]

gotcha.

And if I get a 5950x I will also need to lower my ram's Freq down to probably something like 3600-3800 correct?

[sudden torrent]

3600-4000 depending on what the fclk likes

[steady lance]

Noted.

Would a 3080 ti be a decent upgrade? There's a 3080 TI FE being sold for about $110. My current GPU is a RTX 3070.

[sudden torrent]

No way in hell a working 3080 ti gets sold for $110

The broken ones go for $300 lol

[steady lance]

Seriously?

There were a lot of bids sitting at $100-150 for 3080.

[sudden torrent]

Yeah and most people bid in the last hour of the listing

Look at "completed items" not auctions with 6 days left

[steady lance]

oof.

[undone flame]

Yo anyone got suggestions on ddr5 will mostly be playing tarkov. Price dont matter

[steady lance]

Ahh okay. You willing to spend $899 on some quality DDR5?

[undone flame]

I'm willing to look

[steady lance]

Lmao I was just kidding.

[undone flame]

I'd be interested if it's the only thing like it. If I can get something of near the same value I'm fine.

You know what I mean?

[steady lance]

If you can find something close for cheaper you'd be happy with that?

Is that what you're trying to say?

Not sure what do
dies OC well on DDR5 so I can't help much there however I do know that beyond 7400mhz there's been a lot of talk about it being very unstable.

[ancient bridge]

Ryzen 5000 or intel

If you're on ryzen just get a 6000mt/s kit

[undone flame]

Intel

[sterile flame]

Hynix A die is the holy grail. M die is good too. everything else is kind of meh by comparison

[ancient bridge]

Yup

[undone flame]

Intel homie

[ancient bridge]

I saw

[steady lance]

If your on Intel you can probably get DDR5 beyond 6400mhz to work stable. Not guaranteed though.

[undone flame]

Yeah I'm trying to find some okay kits

[steady lance]

Something like 6400 cl36 would be pretty decent.

If you want you could try to find a 7200mhz kit but not guaranteed to work.

Also beyond 7200mhz you are likely to run into high instability.

[proven canopy]

With 13th gen, a good board, and sr a-die kit, I wouldn't say likely

[steady lance]

SR-A die?

I am not very knowledgeable on DDR5 dies.

[proven canopy]

single rank hynix a-die

Like a gskill 7200+ kit, maybe some 6600/6800

I forget where the 100% a-die cutoff is. You can tell by the serial.

[mental turret]

@modern walrus you've done a lot of S8B OC on Z490 right

[modern walrus]

More Z590 because my Z490 msi gaming carbon wifi was pretty meh but with both 10th & 11th ya

[modern walrus]

Motherboard matters so much for ddr5. My Unify-X was a mission to get 7800. Apex is a mission at 8600

[mental turret]

Same difference, but you've done a lot of rkl right?

[sudden torrent]

Too bad the IMC tends to have super random instability past 7200-7400

[mental turret]

@short blade wanna compare ddr4?

[mental turret]

seems oddly fast for 3600C16 bin S8B
1.95vdimm .95vtt 1.4sa/io

[ancient bridge]

Slow

Cant even beat my ddr2 smh

[mental turret]

@sudden torrent thoughts?

[sudden torrent]

I have no context on that

I don't usually run vst except in certain situations

[mental turret]

Well vst is just the chosen stress test in this scenario, I'm more curious about the result

I don't have much of a reference since I only very occasionally bench ddr4

[sudden torrent]

Right and the result is what I have no context on

[mental turret]

Oh okay lol

[sudden torrent]

I could run it now maybe and compare

[mental turret]

What does your best 1R S8B do? What're they rated for?

[sudden torrent]

My best kit does 4400 c19 rated, I can tune it to 3800 14-12-12-28

With both kits I'm running 3600 14-13-12-28

[mental turret]

Isnt 4400 flat 19's faster than 380014-12-12

[sudden torrent]

Not on ryzen

[mental turret]

Oh because of fclk

[sudden torrent]

yep

[mental turret]

Thats a bummer

[sudden torrent]

Can't do c13 because of GDM too

I'll take free stability though

[mental turret]

You should consider buying a Z590 OCF and 11900k or something. the board is still 135 new. can hook you up with the mem oc special sauce bios too

[sudden torrent]

If I was going to get a board for memory OC I'd get a 2 dimm board, maybe an ITX

[mental turret]

yea thats a 1DPC

I was pretty set on buying it actually until I had no reason to

[sudden torrent]

Like me
I have no reason to. My 5800X crushes the 11900k.

[mental turret]

yea i meant mainly for ddr4 OC if you happened to be interested enough in that

I still might buy one relatively soon-ish despite having access to and currently using a Z490 Apex

[sudden torrent]

I can't justify having hardware taking precious storage space and not doing anything. My wife already complains enough about my spare hardware, even after I built her computer and her brother's using it.

[mental turret]

ah, the wife dilemma

https://hwbot.org/submission/5146383_floppabtw_cinebench___r23_multi_core_with_benchmate_core_i7_11700k_16582_cb

we're matched lol

you may crush a stock 11900k but def not a good overclocked one

[sudden torrent]

And yet I beat this https://hwbot.org/submission/4817221_akm_cinebench___r23_multi_core_with_benchmate_core_i9_11900k_16825_cb

Custom liquid cooled 11900k

[finite frigate]

and i beat chips at 5.9 cause theyre crap bins

lol

[mental turret]

That OS looks terrible

[finite frigate]

mine? it is

that was a stock w11

lol

[mental turret]

I can run a 11900k if you'd like to compare @sudden torrent

[finite frigate]

should do 17.3k on a good one ish

[mental turret]

No, the custom loop one

[finite frigate]

ah

mines worse lol

i can prolly match or beat fal on a good os

[mental turret]

7zip is more interesting than cinebench but oh well

[sudden torrent]

I didn't even bother optimizing my r23 bench os, I lost badly to other 5800X's because if it

[sudden torrent]

That heavily favors ryzen tho

[finite frigate]

i can also do 5.3 on this chip so i wasnt doing the peak

and yet i beat you

[mental turret]

It does? How come

[sudden torrent]

I've done 5.15 since I posted that sub

[finite frigate]

it likes ram

[mental turret]

?

[finite frigate]

7z

lol

oh thats y curnch

oopsi

[mental turret]

Rkl is better at mem oc

[finite frigate]

oh im not giving reasons

im just saying

lol

[mental turret]

Not to mention imc freq

[sudden torrent]

Gee what do we have here I wonder... https://hwbot.org/submission/5224900_forks_7_zip_ryzen_threadripper_pro_5975wx_450161_mips

[mental turret]

Why are you comparing that to a 11900k

I'm talking about your 5800x vs 11900k

[sudden torrent]

It caught my eye and I've had a few lol

alright alright https://hwbot.org/submission/5169590_forks_7_zip_ryzen_9_7950x_292938_mips

[mental turret]

I'm gonna assume you're just looking at subs for fun

[sudden torrent]

All the 16x cpu subs are full of 7950X chips

[finite frigate]

itnel doesnt have a 16x lol

not a good one

avx512

[sudden torrent]

Intel has that disabled but Ryzen only has fake 512 that's actually 256+256

[mental turret]

7zip doesn't use any avx512 I thought

[finite frigate]

iunno

[sudden torrent]

At any rate here's my half trying 7zip https://hwbot.org/submission/5179919_falcie_7_zip_ryzen_7_5800x_111188_mips

[mental turret]

Hm

[sudden torrent]

Again that was before I started trying bclk oc

[mental turret]

I shall beat it with my 11900k tomorrow

And freshly binned bdussy

[sudden torrent]

Please do so it gives me a reason to try

[mental turret]

Ping me at like 2pm in case I forget lol

Unless you forget too

[sudden torrent]

Just saying, there's a lot of 5800X's before the first 11900k (which is on dice) on that bench

SO MANY ROYALS

[finite frigate]

i want the red and black dimms on the bottom

[finite frigate]

all but 2 kits there are royls

silly

[mental turret]

3

[zenith palm]

royals 🤢

[mental turret]

One of them just has the royal diffusers on them

They're neos iirc

[proven canopy]

Nice, I would add a color gradient to mhs and timings though

Also no reason to have columns for m12a, cr, gear etc if they never change

Would also add a screenshot of astc to show what timings the board was auto'ing

[ancient bridge]

In other words

(Redo the whole thing)

[mental turret]

[mental turret]

im already regressing back to ddr3 😔

[sudden torrent]

But if they could change in the future it's good to have

[short blade]

regressing?

you mean progressing back from your regression to ddr4

[mental turret]

YOURE RIGHT

[proven canopy]

That won't make for good binning data. In practice on you'd never want to do that unless by accident

[sudden torrent]

That's true. Ideally you'd want 1:1 control data, and only the variable you want would change.

It's still good to note though so maybe put that info at the top instead of in columns

[proven canopy]

That's what I do

Definitely record everything relevant, just a single line in the spreadsheet plus a screenshot of astc/zentimings along with full hwinfo in case you miss something

With all independent variables identical aside from the chip, as long as you can see a decent range of variation in performance relevant to your eventual benching use case, the method is sound

[steady lance]

What is the difference between Rev-E and B-Die? I forgot.

[sudden torrent]

Rev E clocks high and is easier on the memory controller
B die clocks pretty high and gets very tight timings
Ryzen likes B-die because of the tight timings

[steady lance]

Gotcha, so B-Die is better for me then.

Kinda enjoying the ram oc scene so I am poking around to see what B-Die kits I can find used on Ebay.

[sudden torrent]

Yep. Ryzen doesn't clock memory as high so you want timings as tight as possible. (not mentioning the 5000g chips ofc but even those don't get as high as intel)

[steady lance]

what's the best B-die for DDR4?

[sudden torrent]

All b-die is more or less the same

Unless it's on a bad PCB like corsair uses

[steady lance]

gotcha

could you confirm if this is B-Die for me?

It's not using a standard 042 code.

seller claims it's "sammy b-die".

[mental turret]

that is not bdie

[sudden torrent]

Probably C die tbh

Seller probably loaded thaiphoon and it said b-die

[steady lance]

oh

[mental turret]

thaiphoon is so bad 🗿

[short blade]

my low bin b-die says no

also, there's even lower bin b-die

there's b-die that genuinely won't do better than 3200 16-18-18

there's also b-die that genuinely won't do better than 2133 jedec

b-die has the most variance of any common IC

[short blade]

unlikely, but theoretically possible that this is b-die

99.99999% chance it's c-die though lol

[sudden torrent]

It's also super common because it can be on literally any bin of sticks, but yeah a good bin would be ideal

[short blade]

thaiphoon straight up cannot tell the difference between b and c-die

[sudden torrent]

"Samsung? IT'S B_DIE"

[short blade]

absolute bare minimum b-die bin you should look for is 3200 14-14-14 1.35v

[steady lance]

Gotcha.

[short blade]

even some 3200 14-14-14 kits are pretty cursed

like mine

3600 16-16-16 1.35v bins can be treated as equivalent

the easiest giveaway that it's binned b-die is flat xmp timings

or tRCD/tRP only being 1 higher than tCL

[steady lance]

are all corsair ram pcbs bad?

[sudden torrent]

Yes the straight timings are what gives it away. Rev.E can't do some timings below 18 at that speed.

[short blade]

like 3600 14-15-15 or 4000 14-15-15

those will be b-die

other ICs will be more like 16-18-18, 16-19-19, 18-20-20, 18-22-22

[sudden torrent]

https://tenor.com/view/michael-scott-creasing-forehead-the-office-office-absolutely-gif-11888908

Treat them like they're garbage and they won't disappoint you. If they do well it's a nice surprise.

[steady lance]

so no corsair then got it.

[short blade]

if you want to mess with b-die you should be prepared to put a fan over it

doesn't matter if it's an elegant solution that clips onto your dimm slots or something

or just a fan sitting loosely on top of your graphics card

but case airflow won't be enough

need a fan blowing directly onto it

[sudden torrent]

Eh, not unless you want to push voltage. It does pretty well at 1.45v with just ambient flow.

[short blade]

why buy b-die to stay at such low voltages? smh

[sudden torrent]

Fair lol

[short blade]

if you're not dailying 1.6v+ are you even using b-die

[sudden torrent]

2v lezgo

[steady lance]

I plan to stick my 180mm sickleflow fan above my ram and VRMs.

That seem like enough?

[short blade]

lol gary ran the sticks i have at 2.2v

[sudden torrent]

Actually I got negative scaling on my adata kit past 1.54v

[short blade]

define "above my ram and vrms"

if it's not directly above your ram then it's not good enough

[sudden torrent]

5950X on a ds3h

[steady lance]

Directly above the two blowing onto it is my plan.

[mental turret]

2V 💪

[short blade]

but like

is it big enough that the entirety of the ram will be covered in direct airflow

[short blade]

yeah it was mostly a joke

my kit hits negative scaling right above 1.60 lol

at least at air cooled temps

[steady lance]

I believe so, will check tomorrow.

[sudden torrent]

Ye
The vipers I got do pretty well though. I pushed them up to 1.8v when I was testing a few days ago

[short blade]

gary saw scaling to much higher voltages but he also had a water block on them

[steady lance]

the fan is massive.

also, is Micron B die good?

[sudden torrent]

Rev B?

[short blade]

16 gbit micron rev. b is good

[sudden torrent]

It's ok but not as good as sammy

[short blade]

but not as good as b-die

[mental turret]

The best of the 18 low-bin sticks of bdie I was binning does 2368-12-13-13 2V

[steady lance]

Cheapest 32GB B-die kit I can find is G.Skill Trident Z Neo.

[mental turret]

passed 2 loops of vst 🥴

[short blade]

avoid rgb on b-die if possible (or just leave it off)

rgb heatsinks tend to be worse than useless

[steady lance]

even if there's lots of air flowing through?

[sudden torrent]

Yeah RGB adds heat and insulates it at the same time

[steady lance]

I suppose I will leave the RGB off then.

[sudden torrent]

Plastic doesn't conduct heat as well

[short blade]

you're sacrificing metal surface area for plastic led diffuser

and also adding a heat source to it

[steady lance]

Is delidding risky?

[mental turret]

can just remove it lol

[mental turret]

depends on how you do it

[short blade]

it's pretty low risk if you have access to a heat gun

[mental turret]

for dimms that dont use epoxy or absurdly strong adhesive on their heatspreaders, soaking it in iso for 12h+ works really nicely

[short blade]

if you just tear it in half with guitar picks like a psychopath, it's a bit riskier

[mental turret]

idk which ddr4 dimms use what kind tho

[short blade]

managed to not kill any of the 4 sticks i delidded that way though

[sudden torrent]

You're making me want to add ram to a custom loop now

[steady lance]

usually the way I do it.

[short blade]

lol i'm sure gary has some advice for you

[steady lance]

Hair dryer work?

[short blade]

probably

[sudden torrent]

Doesn't get quite as hot usually but it could work

[short blade]

i upgraded his b-die water block to something much better though

[steady lance]

Did this to open up my phone to replace battery.

[short blade]

ddr3 heatsinks

[steady lance]

Is Samsung B Die really that much better compared to Micron B-Die? $100 for Micron vs $170 for samsung.

[sudden torrent]

Honestly for most people it doesn't matter, but if you're overclocking you want every drop of performance

[short blade]

for practical purposes? no
if you are wanting it specifically to oc? yes

both prices seem high though unless you're looking at 64gb

[steady lance]

32Gb.

[short blade]

$170 is a lot

[steady lance]

agreed

[sudden torrent]

I found a kit for $160 brand new in 10 seconds

[short blade]

i want to put my daily b-die kit in a ryzen system now

just wanna see how much easier it is to tune

[sudden torrent]

SCL 2 go brrrrr

[short blade]

i should have done it with the 5800x3d i had

[sudden torrent]

Interesting kit, never heard of the brand but looks like it could be b-die https://www.amazon.com/dp/B0BXFY1KSQ?tag=pcpapi-20&linkCode=ogi&th=1

[short blade]

definitely b-die

no other IC can run that

[sudden torrent]

The only question is PCB quality then. It's not a great bin but decent.

[short blade]

there's a very silly mushkin kit that's 3600 14-19-19 1.5v xmp

perfect for people who think tCL is important i guess

3600c14 is 3600c14 right

[short blade]

it's a lot better than mine lol

my b-die does 3600c14 at 1.55

[sudden torrent]

I was doing 3800 14-13-12 at that voltage on my adata kit

[short blade]

i'm very curious what they're using in this kit

[sudden torrent]

It was binned for 4133 c19 though

[short blade]

rev. e maybe

[sudden torrent]

Could be, or rev.b tbh

[short blade]

i have a 3200 14-14-14 1.35v bin

daily 4133 15-15-15 at 1.60v

on the i3 i dailied 3600 14-14-14 at 1.55v

it seems this kit doesn't like running primaries that aren't flat

[sudden torrent]

Weird

[short blade]

if i change 15-15-15-35 to 15-16-16-36 without changing anything else, it fails to post

[steady lance]

3200 14-14-14-34 is definitely Samsung B-Die correct?

[short blade]

yes

[sudden torrent]

yes

[steady lance]

Found a g.skill kit on amazon.com.mx for about $200 for that xD

[short blade]

if it's ripjaws delidding is gonna be basically mandatory

[steady lance]

tridents

[short blade]

my kit is 2x16 3200 14-14-14 ripjaws

i'm not sure about the tridents

[steady lance]

Are the ripjaws really that bad?

And if so, should I consider delidding then relidding mine?

[short blade]

without airflow they easily get up to 80c

still suboptimal with airflow

[short blade]

why relid?

you can just run them bare

[steady lance]

aesthetics of course.

[short blade]

or use aftermarket heatsinks if it bothers you like it bothered me

relidding would not help/would make it worse

[steady lance]

By relid I mean putting on new heatsinks.

[short blade]

ah

[steady lance]

Like a aftermarket one.

[short blade]

yeah i did that

bought some ddr3 kit just to rip the heatsinks off

turned out to be actually decent ddr3

[sudden torrent]

I'm not sure if far would laugh or cry at that

[short blade]

well, i didn't kill any of the sticks

i actually oced and benched them

PSC isn't temp sensitive enough to care about those heatsinks apparently

[steady lance]

damn if only I didn't need 32gb of ram....

[short blade]

sold them to danny after so he could use them for benching purposes lol

[steady lance]

8gb B-die sticks are so much cheaper.

[short blade]

8gb sticks cheaper cause nobody wants them lol

why buy 16gb b-die when 32gb of normal ram is probably cheaper

[sudden torrent]

I run 4 sticks b-die
It sucks lol, can't go above 3600

[steady lance]

Does running 4 sticks affect cas?

[sudden torrent]

Not really

[short blade]

cheapest 16gb b-die rn is $47, also looks like probably the worst heatsink humankind could possibly imagine

cheapest 32gb 3200c16 is $49.97

imagine buying this just to delid it

full plastic lol

no useful surface area

[sudden torrent]

Hey it'll be easy to delid at least

Just snap the plastic

[short blade]

lol fair enough

[steady lance]

3600 Cl16-16-16-36 is also b-die yes?

[sudden torrent]

yes

Probably

[steady lance]

found 2x16gb Royal Silver sticks at those speeds for $155

[short blade]

only jedec and b-die ever have flat timings

[steady lance]

Owner says it's a B-die kit in description

[short blade]

and you don't have to worry about it being jedec because well

it's quite obvious

[short blade]

it's b-die with 100% probability

like we said

no other IC can run timings like that

[steady lance]

gotcha.

[short blade]

it's low bin b-die though, so results may be unpredictable

[steady lance]

What do you guys say 2x16GB B-die kits are worth?

[mental turret]

what does your best of this bin do

how many do you hnve

have

[short blade]

uhhh i think the country we live in prevents us from giving you a good estimate on this

brand new 2x16 b-die is $105 here

[short blade]

just the one kit

[mental turret]

o

[short blade]

this is the only b-die i've ever owned

[mental turret]

o^2

[short blade]

i haven't tested what it can really do

i'm just at my 4133 IMC limit

[mental turret]

which chip?

[steady lance]

does ebay auto set it to mexico for me?

[short blade]

never tried gear 2 like you're doing your binning with

13700K

[mental turret]

o

[mental turret]

why not?

[short blade]

no idea

[short blade]

let me finish my daily profile first lmao

[mental turret]

bruh

[short blade]

you have no idea how frustrating this platform is

[sudden torrent]

Gah I really hate amazon's search.
Search terms: 32gb ddr4 3600 cl14

[short blade]

every voltage needs to be on the exact perfect tick

[sudden torrent]

(╯°□°)╯︵ ┻━┻

[mental turret]

yea, rpl seems to be pretty odd from what ive heard

RKL >

[short blade]

dude

if i raise my VDDQ by 0.05 from what's stable

a single tick

my OS is gone instantly

lol

if i lower it i can expect thousands of errors in seconds

now imagine trying to find the perfect tick for that

while also remembering that the value that it needs to be MOVES depending on your timings

[steady lance]

is 3600 cl15-15-15-35 a good bin @ 1.35v?

[sudden torrent]

There's a reason the 11900k still holds all the DDR4 records

[short blade]

it needed to be 1.315V at 4133 16-16-16, 1.320V at 4133 15-15-15

and then

you think you found the right tick

but can you really be sure? when you get an error at 20000%?

[sudden torrent]

meh

[short blade]

is it vddq? or is e-core l2 cache voltage on the wrong tick?

or is it SA?

or are your RTTs off by one tick?

or are your ODT finetunes off by one tick?

or is your RX equalization off by one tick?

or do you have the wrong write slew rates

or maybe you just degraded your cpu core

oh but what if your ODT read delays are off

or maybe it's your ODT write delays

[steady lance]

wait, would the bin affect how low I can drop cas or is it just freq?

[short blade]

or maybe it's tWR, that timing is known to error super intermittently, right?

oh you loosened tWR and now it doesn't post

[steady lance]

Cus if I remember right, it's highly unlikely I will get ram to work with a 5950x above 3800mhz.

[mental turret]

@short blade

[short blade]

so many variables have to be absolutely perfect with RPL

yeah literally

that emote is me

[mental turret]

[sudden torrent]

Some of column A, some of B

[short blade]

without a doubt the worst platform i've ever used

still haven't solved boot to boot variance either

[sudden torrent]

Those 3600 15-15-15 sticks would probably be fine. Not super amazing but still good enough. 3800-4000 c14 should be easy.

[short blade]

at this point i'm just hoping to drive myself crazy enough that i pull the trigger on a 7800x3d

[steady lance]

do it!

[sudden torrent]

https://tenor.com/view/good-yes-emperor-palpatine-star-wars-excellent-gif-16144278

Give in to those feelings

[short blade]

only reason i haven't already is that the boot to boot variance does seem to be getting better as more voltages get locked into the exact perfect tick

[steady lance]

Found a 4266 cl19-19-19-39 Samsung B-Die kit for $140.

$170 after shipping.

[short blade]

but man

it's insane how easy ram oc is on ryzen

i was expecting my first ever ddr5 kit to be more of a struggle

instead everything just worked

[sudden torrent]

Because they don't need to worry about packing a DDR4 and a DDR5 compatible IMC into the chip

[short blade]

the board figured out how to do everything on its own as soon as i selected ddr5-6400

you know what

that's fair

older intel platforms were so much easier too

then again

those had ddr3 IMCs...

[sudden torrent]

This was an issue around, what, 6th? gen intel with the transition to DDR4 too

[short blade]

even comet lake had ddr3 IMCs too, no?

[sudden torrent]

idr

[short blade]

iirc some comet lake laptops still used lpddr3 since lpddr4 took a while to get going

so ddr3 support was maintained until 10th gen

[mental turret]

ddr3

omg

[short blade]

can't actually access the ddr3 IMC in desktop comet lake though

you can with coffee lake

[steady lance]

8810B means it's Samsung B-Die at 16gb per dimm right?

[sudden torrent]

yes

[short blade]

9900KS + ddr3

[sudden torrent]

That'll be dual rank 8Gb B-die

[short blade]

my 6700Ks and 7700Ks never gave me issues with ram oc like this 13700K does

the 12100 didn't either

[steady lance]

description from the seller claims it's 2x8gb

[sudden torrent]

Yeah that's a 16GB kit, 2x8GB

[short blade]

please don't buy this lol

4266c19 is not even a good bin

[sudden torrent]

Looks like your memory serves you well

[mental turret]

lol the seller doesnt know how to take photos

[short blade]

yeah

so I don't think the issue is that it has two IMCs

cause so did the 10900K

[steady lance]

not getting this due to lack of capacity but seems like a decent binn. 4000-cl15-16-16-36

[short blade]

it's meh

2x8 4000 15-16-16-36 1.5v

I believe the best xmp bin is 2x16 4000 14-15-15-35 1.55v

not really worth paying the premiums that those kits command though

[steady lance]

especially considering that there's like no way in hell I am gonna be able to run 4000 with a 5950x

[short blade]

it's possible

not likely, but possible

[sudden torrent]

What cursed kit is this? 3200 c16 at 1.55v? https://pcpartpicker.com/product/g6JgXL/mushkin-redline-lumina-white-32-gb-2-x-16-gb-ddr4-3200-cl16-memory-mlb4c320gjjm16gx2

[mental turret]

tempted to buy some of these in bulk at some point lol
https://www.ebay.com/itm/173978139762

[short blade]

probably a mistake on pcpp

have seen mistakes on pcpp before especially with details on niche ram kits

there was a supposed 3200c9 xmp kit

that was 3200c13 in reality

[sudden torrent]

Newegg says 1.55v too tho

[short blade]

hmm interesting

buy it and find out

[sudden torrent]

omfg even the mushkin site http://www.poweredbymushkin.com/Home/index.php/products2/item/247-lumina/1720-mlb4c320gjjm16gx2#specifications

What cursed memory die is on those?!

[short blade]

is there even any IC that exists that needs 1.55v for 3200 16-18-18?

that has to be at least 8 Gbit density

[sudden torrent]

Maybe D-die? lol

[short blade]

since these are 16gb dimms

[steady lance]

https://www.ebay.com/itm/235020111736?hash=item36b84a4f78%3Ag%3AT0gAAOSwcStkTxyK&amdata=enc%3AAQAIAAAA4Na%2B%2Bg%2BWrdNqovwpFEuf%2F%2FlcMlLmkePowr6n%2BSZ7FBXmXjqjx8YkXihumsiXePL62wyJ2u7Wed5R%2Bk3me5hYsiNlsnFNQ7TctP4d%2BeXkdltgUzZ5t7VKXw5eCFJ%2FueMG%2F7Y1ASg%2B0YeifyiPrY6Hd2ojCQejPT75mTs5N75p3fgWBcvWU7LkGrHP1Ytgr5WGgDPBpbWlCt%2FScxJF0zHPyv4mFleSxE47cIMZNBoRdI7efKfw4FN5Nl6sTsp8Kb0W5ex911HSzPvGxybuX4hiLJY7qAx2TbQjquNMNJoN6ghA|tkp%3ABk9SR87UjvuIYg&LH_BIN=1

this is quite tempting....

very very tempting.

[short blade]

my d-die sodimms do 3600 19-20-20 at 1.25v

d-die isn't that bad

to need 1.55v for 3200c16

[steady lance]

Cheapest b die I can find on ebay that ships to me.

[short blade]

better to avoid 4 dimms if you can

[sudden torrent]

4x8GB b-die, that could work if you accept that the speed might not be great

[short blade]

worth paying a bit extra for 2x16

unless you happen to have a t-top board

and you don't

[sudden torrent]

It's a ds3h so... yeah lol

[steady lance]

B550M DS3H so definitely no.

[short blade]

are t-top boards even still made?

I don't hear much about them anymore

[steady lance]

t-top board?

[mental turret]

of course

[sudden torrent]

I haven't seen any for DDR5 personally, because 4 sticks DDR5 is ass

[steady lance]

What's a t-top board.

[short blade]

t-topology memory trace layout

all 4 dimms slots have equal length traces to cpu

so the board performs better with 4 sticks than with 2

[steady lance]

Oh interesting.

[short blade]

99.9% of boards are daisy chain

[mental turret]

Hopefully my 2 best bdie I binned perform similarly when running together. gonna go after #1 ambient scores on the 11900k

[short blade]

shortest traces are to the preferred 2 slots, then the other 2 slots daisy chain from those

[steady lance]

With 4x8gb would I still be able to hit 3800mhz?

[short blade]

so it performs better with 2 slots populated than 4

[steady lance]

or is that unlikely

[sudden torrent]

I can't but it's possible

[steady lance]

what do you get?

[sudden torrent]

3600

[short blade]

running 4x8 probably won't limit you from hitting 3800 but may have more impact on what timings you can run

[mental turret]

what're your dimms? or do you just mean bdie in general

[steady lance]

Samsung B-Die.

[short blade]

just avoid it, if you're committing to paying for b-die you might as well commit to paying for proper b-die

[mental turret]

what CPU?

[steady lance]

Cheapest 32GB total capacity is a 4x8gb S8B G.SKill Ripjaws.

[short blade]

5950x

[sudden torrent]

My daily with 4x8GB, I can't get more than 3600 no matter what I do

[steady lance]

Currently a 5700G upgrading to a 5950x in the near future.

[mental turret]

oh 💀

[short blade]

those are some wacky looking rtts

because of the 4 sticks I'm guessing

[sudden torrent]

yes

[steady lance]

sounds like me with 3933mhz 😭

[short blade]

have you messed with drive strengths or setup times at all?

[sudden torrent]

Yes

[short blade]

higher vsoc or vddg iod?

[sudden torrent]

Yes

[short blade]

lower vtt?

my b-die doesn't like being at 0.695 or 0.705, must be 0.700

[sudden torrent]

higher and lower of all of the above, just in case

[short blade]

higher tRC?

[sudden torrent]

I tried 3800 24-24-24-24-60 with 90 tRC

No post

[short blade]

oof

were you ever desperate enough to try 2T

[sudden torrent]

Nah I'll take a 200MHz hit lol

[mental turret]

i should really get on top of figuring out what my MFR can do lol

[steady lance]

S8B 3600cl16-16-16-36 vs 3200cl14-14-14-34 which is better?

[short blade]

was wondering if you did it for science

[mental turret]

are there flat 16 bins for Cdie?

[short blade]

if they say S8C is doing flat 16s they're just lying

hmm did you try looser tRRD_L?

[mental turret]

anyway, if bdie, 3200C14-14-14 1.35V > 3600C16-16-16 1.35V

[sudden torrent]

I did all timings on auto besides those primaries

[short blade]

my b-die seems to need to loosen tRRD_L to 6 above 4000

[mental turret]

thatsb die lol

[short blade]

that's b-die

[steady lance]

Oh whoops.

I put in S8C

[mental turret]

do you strictly want dual rank bdie?

[steady lance]

I meant to put S8B

[sudden torrent]

Ideally, for the eventual 5950X upgrade

[short blade]

he needs 32gb

[mental turret]

ah

[short blade]

so it's gotta be 2x16

[steady lance]

Yeah, and I plan to upgrade to 5950x in about a month or less.

[mental turret]

I honestly wanna daily 4x16GB bdie

[sudden torrent]

Unless you do a mobo change yeah 2x16GB is ideal

[mental turret]

Was looking at an ebay listing the other day

[short blade]

you should daily those cursed quad rank dimms

[mental turret]

https://www.ebay.com/itm/285296143096

[mental turret]

platform i'd be dailying doesnt support rdimms

[steady lance]

Would a mobo upgrade be better first compared to ram for the 5950x given I currently have some decent D-die ram?

[short blade]

there's quad rank b-die dimms

[mental turret]

arent they all rdimms

you're not confusing 2Rx4 for 4Rx8 are you?

[short blade]

tbh not sure

trying to find the picture bc it's hilarious

[mental turret]

either way im pretty sure all 2Rx4 dimms are buffered anyway

[sudden torrent]

It could be worth it assuming you can find a t-top board for cheap if you want 4 sticks, since better VRMs could help too. Then you wouldn't need a fan.

[mental turret]

bruh?

[short blade]

💀

[mental turret]

have a part number?

[short blade]

no unfortunately this is all I have

[steady lance]

what boards are t-top?

[mental turret]

lmao well its bdie

[short blade]

supposedly they were some royals prototypes

[sudden torrent]

Them's tall royals

[short blade]

32gb per dimm

for when you really want to daily 256gb of b-die in your threadripper system

[mental turret]

https://www.anandtech.com/show/13694/double-height-ddr4-gskill-zadak-2x32gb-ddr4-3200/8

[short blade]

256gb b-die at 3200 18-18-18

flat timings!!!

[steady lance]

has anyone tried that?

[mental turret]

@rancid seal but faster

i think lol

[short blade]

uhh good luck getting 8x32gb b-die

[mental turret]

16x16GB 😎

man i have work, i should sleep 🗿

but OC talk gud

[steady lance]

anyone know which boards are t-top?

[short blade]

"DDR4-3400 14-14-14 at 1.5 V"

[mental turret]

@short blade did you see the laptop i posted earlier today

[steady lance]

Also, how does a 5950x perform with a 4090 out of curiosity?

[mental turret]

lol

[mental turret]

doesnt bottleneck if thats what you;'re wondering
