Wait, so is it like tREFI where I want to just keep upping till unstable?
Yes
Until stable
The lower you go, the less temp headroom
And the slightly faster you are
Until a theoretical limit per the ic
So tune all the tRFC as high as I can?
tRFC you want low, tREFI you want high
Start at the expected number, increase until stable
Oh okay.
Start at 500 400 300
I run 720 because anything lower and I can't daily my ram over like 60C
Do I repeat this for all the tRFC valuies like tRFC1, 2, 3?
The max for tREFI is 65535 iirc
I'd much rather having up to 90C headroom
AMD only cares about tRFC1, the other two might as well not exist
Mhm
They work in blocks of 4 8 or 16
for whatever reason my pc did not like to boot at max tREFI but 65k boots and works fine.
Which is fine
So just leave them on auto?
Like I said, 64K, 32K or don't bother
also idk what is going on but somehow my average ram temps keep getting lower with each tighted timing?
tRFC2 and tRFC4 can be auto, the memory controller doesn't use them
Wait. 🤦♂️ just realized why.
I was not running my AC during testing before, been keeping my ac at 20c lately.
Thanks for the heads up.
It's ambient then
Which you should really run your maximum ambient if you plan to run this in an inch of it's life
1.6v will show temp errors quick if it's only a couple C over what's comfortable
Any specific things i gotta do for the other timings in primaries or do I just lower everything from here on out and turn FCLK up as high as I can?
I have not seen my ram go past 50c since I installed the fan.
usually around 45c during load
Also
You haven't done trfc yet so you probably have a lot of headroom
Is it possible for it to be whatever that B die you guys mentioned before?
Gotcha.
If you're unsure, send a pic of the sticker
Kingston has a code system?
Ahh will definitely check that later.
But this will show you it's hynix
sticker on the ram right?
Mhm
Find the vSOC sweet spot, it's usually around 1.1-1.15v iirc. Exact number varies by bin.
Just run 1.25vsoc
Ask @proven canopy for a good fclk test
I used mlc gui and ran 10 passes of each
To check theoretical speed
From what I've seen vsoc too high causes regression
Since it's perma desync
Meh maybe
I think basically everyone runs either 1.25v or 1.3v
That might have been because that was the auto setting on the board before the agesa patch that keeps them from blowing up
Mhm
A lot of boards just auto 1.25+ to my knowledge
It's a bit different to AM4, fclk just spits perf regression not stability regression
You don't really get wheas just ecc scaling back
Yeah and I've seen the oscilloscope to prove it, silent errors
Yep
Forks has a better test that I can't remember the name of
I used mlc gui tho and ran 10 passes of each fclk over 2000, took the fastest of average 10 (2133)
ycruncher?
Hynix confirmed
Told u
Now if you manage a low trfc then you 100% have A
I'm like 95% sure from the sub 50C 1.6v behaviour though
low trefi or trfc
Happens to the best of us
I feel like the old wise man and fal is my aid
"No felix you meant trfc"
"WHAT? WHAT DID YOU SAY?"
"LEMONS?"

Oh man I'd kill for one of those rn
Enjoying your summer then?
Gotta love when it's so humid you can't even sweat
Gotcha.
Agreed.
Felix do you by any chance know at what voltage A die starts having deteriorating?
Based on what I've read 1.6v is kinda the upper limit so long as it's cooled but I am not sure what voltage A die can handle beyond that.
to my surprise, tRRDS just booted at 4.
tRRDL at 8 should too
I got it stable at 6.
tRRDL 5 did not wanna work.
Just booted tWTRL 23 from 26.
22 refused to boot
Just got tWRLS 5 to boot.
4 was a literal 50/50 shot of boot or not boot.
Are you stress testing these changes?
My strategy is to get a handful of timings to boot, run TM5 if it passes TM5 then I later run OCCT at 90% for a few hours.
If a error occurs I go through each one of the timings I tuned one at a time with same strategy.
got these settings to pass TM5, temps peaked at exactly 50c, averaged around 47c under load.
with that I've tuned all my tertiary and secondary timings at 1.6v
tRFC1 did not boot at 450. Trying 500 now.
tRFC1 500 boots.
Should I leave tRFCsb on auto as well?
Gonna try 475 if this passes.
passed TM5, gonna try 475 also tempts went up by about 2c in the left dimm.
Welp it did not boot, reverting back to tRFC1 500.
No but it does influence tRAS
tRP will have the most effect of those
Just saw your message and I've been tuning tRAS? Will double check in a second.
I'd do tRP, tRCD, tRAS, then tRC
Kay.
No formulas required?
tRC = tRP + tRAS right?
Any formulas for the other 3?
tRAS = tRCD(RD) + tRTP
tRC = tRP + tRAS
Obviously if any of those make it unstable, increase it
Where do I find RD?
It's one of the tRCD ones, one says WR the other is RD
Yeah
If anyone asks in the future apparently MSI X670-P does not separate.
tRCD 35 booted, trying 33.
32 failed.
33 failed, trying 34.
34 failed.
Tuning tRC now.
got the primaries to boot, current timings.
now running TM5.
Dang it, we got errors.
Turning tRFC1 up it seems to be messing with boot.
Hello, I just installed this (https://pcpartpicker.com/product/zcH8TW/gskill-ripjaws-v-32-gb-2-x-16-gb-ddr4-3600-memory-f4-3600c16d-32gvkc) set of RAM on my PC and have docp turned on but cpuz is reading it as cas 18.
Should I try to boot it up like this?
Or do I need to switch something else up? Thanks in advance!
And voltage like this
Are you trying to overclock or?
Just set it to default timings since docp is setting it up to CAS 18
And my ram is cas 16
Isn't docp just xmp for amd right?
The docp on bios is appearing like it should
Oh okay, for me it's just called X.M.P on all platforms I've been on.
But on boot up on cpu z its like this
The timings are a bit higher
Like my previous cas 18 kit
You have any auto-tuning enabled?
Also when sending picture send whole screen as it's easier to analyze.
I turned it off because the docp auto tuning set them to 16-19-19-39 like they should but when I booted up they appear higher like on the CPU z screenshot
This is how it appears when I just installed the RAM
It appears as it should be working
But when I boot I get cas 18 on cpu z
Strange, what board and cpu is this?
5600x?
Cl16 works fine if you tune it manually?
Haven't tried bc I'm scared I might screw something up.
Is this how you should set it up manually?
Go to your ram section and manually set the cas.
Worst that can happen is your PC won't boot in which case you clear the close to restore stock settings
Yes but make sure you are changing DRAM CAS LATENCY.
Leave voltage the same so we can check if the issue is your ram.
So this is correct?
Just change the values that I changed there?
And leave everything else at auto and the voltage at 1.350 like it is atm?
If those are the same timings as your ram's XMP is then yes.
Correct.
Look at the sticker on your ram.
For 3600mhz
That shows what settings you are running once in boot which can vary.
That's why I set 19 three times
Just occured to me, this is the wrong sticker. Was referring to the one on your ram but this works.
Odd but yeah try booting it.
Okay I'll leave everything like in the screenshot incl the voltage
The dram voltage changed by itself should I manually set it to 1.35?
Or leave it on auto
Set it to 1.35
We are testing to see if the issue is ram or board
If your ram fails to boot at X M.P settings then it's most likely the ram.
hmm
so it booted perfectly fine
but i now have 2133mhz of speed lol
I forgot to set it to 3600
Yeah set the speed.
the timings are right now though no?
Currently I am tuning my own ram to figure out what's erroring lmao.
Yeah looking good also for Ryzen, use ZenTimings.
Gives you all your ram info and I think more accurate.
Yeah.
Can I try to set it to 3800mhz?
Start with 3600.
Okay
Done right you'd do frequency, then timings.
Yeah AMD can be annoying with ram from my experience lmao.
Set it to 3600mhz see if it boots, if it doesn't try adding 0.5v to Dram.
Okay so it booted and I have the full 1799.6mhz
Does this mean that everything is as it should?
Technically yes.
I would install TM5 (in the pins) and run at least one round to test for stability.
Much easier to read right.
Is this the right app? https://www.overclock.net/threads/memory-testing-with-testmem5-tm5-with-custom-configs.1751608/
Yeah.
Just the default config is fine btw.
No, default is not stressful enough. You want one like anta extreme or pcbdestroyer
How do I get those configs to work? I think I followed all the steps but they never work.
Make sure to enable xmp even if you're manually setting everything. It does affect a lot more than you think.
it doesnt let me apply both
What do you mean by both?
i mean, it doesn't let me manually set and have xmp on at the same time
Found the wrong timing. It was tRCD.
That... Shouldn't happen
Every motherboard I've seen has let you enable profile 1 xmp and use that as a baseline
how long does the test last?
okay, ill let the test finish and check again
I often have trouble with the anta profiles but pcbdestroyer usually just works on mine
I probably didnt see it since I didnt scroll long enough
Could you send me the link to the pcbdestroyer config?
Test takes about 10m.
should I stop it, enable xmp, leave the timings as I set them now and restart the test then?
Nah let it finish
Ty
I'm sorry yeah I didn't scroll down enough lol
I'm leaving everything else as I had it
Or should I change something else while I'm here?
Could try seeing if 3800mhz boots.
For now reboot and go back into bios so it sets voltages and sub timings correctly
Btw if you send us a picture of the sticker on your ram, we can help you identify what ram chip (die) you have.
Okay so no rebooting into 3800?
Just leave it at 3600?
For now yeah, you can try 3800 after reboot but I'd recommend finding your memory die first
Okay only changed docp to on
I got the same frustrating error.
opens, gives a ton of error messages, then closes.
Are you running as admin
Yes.
rebooted and got this
is everything as it should be?
should I retest or should I try 3800mhz?
On Reddit it says it has smth to do with the config.
ahhh, let me take out the ram and send you a pic
Like the "Testing Window Size"
At a glance yeah. That looks like micron memory dies to me.
You can get the other sensor data by updating bios and installing chipset drivers.
Ram is in binary right? So 1024MB = 1 GB
Sometimes I've seen the program itself be corrupted, and you need to delete it and re-extract it to fix
Let me get the latest chipset drivers
Technically 1024 MiB = 1 GiB but yes
And update my BIOS
@sudden torrent it worked!
I had to change the Testing Window Size in the config because it was trying to test the wrong amount of ram or smth acoording to reddit,
I should say yes to everything here right?
yes
formula in config is 0.8 multiplied by RAM AMOUNT divided by thread count
Which config is best for TM5 stress test?
Extreme anta is good for a gaming stable test
Pcbdestroyer is a longer test that can find errors late in testing from heat
gotcha.
Omg I had a mini heart attack
I updated the bios but forgot to backup the tpm code
And it didn't let me boot
But I remembered that I had my old bios still downloaded
TPM backup is only needed if you're using bitlocker
I don't know if I'm using it 😅
I don't remember
I went back to the previous bios to verify if I had it on
If you don't know then you aren't most likely, it's not something you can set up when you install windows. It's done after.
Fal, any idea why sometimes all of a sudden when I exit out of bios my PC LEDs don't turn on past CPU lights?
The debug lights or the RGB?
Debug light shows CPU/dram, it gets past that then no lights but everything is spinning
Fast boot
Turn that off?
If it's a problem for you then yes
Disabling that will force bios to recheck things like the GPU even if it registered as ok on the last boot
That is a separate but related thing
okay its off lol
Then you're safe to update and hit "Y" when it warns you about the TPM reset
Any idea where I can find fast boot?
MSI right?
Yes
Yeah that's what scared me lol
I'm updating again to 3404
I'm thinking of getting a 5700x3d when it comes out, It should just be a simple switch when I get it no? Bc I have the latest chipset drivers and BIOS
Looks like they removed it from newer bios versions. They probably rolled it into that memory context restore option.
Gotcha so I wasn't going crazy.
I tried looking for it the other day when Felix mentioned I should turn it off but could not find it at all.
How long does PCBdestroyer usually take?
Between 3 and 8 hours depending on factors
Yeah that's fine
Nice now you can see the fclk and such to make sure it's synced
should I go for 3800 with everything as is?
or do you want me to take out the ram to see the sticker?
yeah this is my kit
Perfect, g.skill has a code starting with 042 or 043 that tells you exactly what die the kit uses
So yes a sticker pic will help speed things up
okay no prob, let me shut it down and take out the panel real quick
Do you need a pic of both?
Or just one of the sticks
Nah just one
Okay
They're a matched pair so it'll be the same code
8821C is CJR
Dual rank CJR so 8Gb
So, the overclocking potential of those sticks will be limited
Okay
You might be able to run 3800 but don't spend too much time trying
Should I just leave it as is?
Or should I try 3800 with everything else like it currently is?
Try 3800 with tCL at 20
If that fails there's little hope of it working at that speed
All three that are 19 at 20?
Just DRAM CAS
Leave the rest as is?
Yes
If it boots, go back into bios and set dram cas to 18 and see if it still boots
Okay
You can set up to 1.4v safely to help with higher speeds and lower CAS
1.45v is on the edge of safety for that die
Any higher and it degrades quickly
Awesome. Looks like you'll need to manually set fclk but that's a minor thing.
Yes
It's because Zen 3 is coded to have a ceiling of 1800 fclk/uclk on auto, but most chips can do 1900 with little effort.
From here you can follow this guide, lots of tips and "why you should do this" https://github.com/integralfx/MemTestHelper/blob/oc-guide/DDR4 OC Guide.md#amd
Or I can walk you through things one by one if you want the TL:DR version
Hmm, can I test cl 16? And if not try that?
Or should I just go through those steps instead?
Also you told me to set this to 1900 right?
Yes fclk 1900. You'll probably need to adjust other voltages to get that working.
CAS 16 is a good goal but one for later
1.10 V SOC
0.95 V VDDP
0.95 V VDDG CCD
1.05 V VDDG IOD
Asus might call SOC "VDDCR SOC"
I can set them individually
Oh I think asus calls manual control mode "override" mode
Then the setting appears below
Ahh it's right there like that lol
Should I leave the vddp standby on auto?
Yes
These are the voltage settings that are known to work for most chips and are perfectly within the safe margin
For now no, you want to check fclk and uclk for errors before you do anything else
Boot windows and open zentimings again
With these settings right?
yes
what should I do now?
Do you have hwinfo
yeah
Ok, have that running and watch the very last sensor. That's the WHEA error one, which is the kind of error the infinity fabric will throw if it's not running right.
A single error means it's not stable
it doesnt have any errors rn
Run your memory test again and watch it
A good 30 minutes should tell you if fclk is stable enough
Oof, well no worries we play with resistances now
I should just stop it right?
Yeah no point continuing
and go back to BIOS
Omw there
Just that?
For now yes
Better to let voltage handle the instability than tweak resistances up to a point
Just run the test again right
Yep, watching that WHEA counter again
Define stable
"Able to run games without losing performance or blue screens" is a common one
There's also "cannot lose any data or reboot under any circumstances" stable
This is enough for the first type lol
Can I use discord on the PC while running the test? Or should I just leave it running alone?
You can
Just open discord first before the test
The test will use whatever memory is available
What should I do next?
Excellent, next you can do trrds and trrdl to 4, tfaw to 16, twr to 16, and trtp 8
Those should all be easy enough for the memory to do at 1.4v
And they speed up testing time
Okay I'm going to BIOS
That's in dram timing control right?
This and retest?
Yep
trrdl 6
Will do
If it survives this test then I'd save a profile in bios so you can get back to this point quickly
100% good practice to do that periodically
I want to do a profile of just the regular 3600 cas 16 stock profile too
For regular use
Well for that all you need to do is reset to defaults and then load the xmp profile
After you save the profile you can set trfc to 500, which sets it to a little over 260ns at 3800. CJR should be able to do 260ns, or if you're unlucky 280ns which would be setting 530.
Don't worry about trfc2 or trfc4, AMD doesn't use those so you can ignore them
I'm sorry to ask, but theoretically, how far am I from cas 16 no data loss stable? lol
We'll find out soon
You want to get SCLs stable before CAS, since they have a higher impact on performance
Where do I make a profile
NVM sorry found it
I should be able to reset now right?
Yep
Can I just default the AI tweaker?
Technically yes
I can't find an option for this lol
You'd need to reset each option to auto lol
Easier to just "reset to defaults" on the exit menu
This should be it right?
Just for regular use and gaming while I'm finished OCing
I'm leaving it at this for regular use.
Atleast we did some good progress today right?
Thank you for everything! I won't be able to continue today, but I'll try Sunday. I'll leave it as is meanwhile.
Sounds good. Enjoy your saturday.
thank you again for introducing me to OC lol
I've been scared of trying it for the longest time haha
Happy to help. It can be scary at first with all the warnings and disclaimers but it's really hard to hurt anything in reality.
yeah that's what kept me away
The only thing that can potentially damage things is voltage, and I'm keeping you well under the safe limits so no worries there
For example, vsoc is safe up to about 1.3v
so voltage is the only dangerous thing here?
the rest only should be harmless bluescreens no?
I'm leaving it like this.
I'll be heading to sleep, thanks again.
Yep the only risk with timings is losing data or corrupting the OS, which are generally easy to avoid or fix
@sudden torrent, my ram survived PCB Destroyer at 52c.
What speeds can most A-die do de-synced?
That's really open ended
Like, 8000+
I'd have no idea for 64gb
Desynced is also a huge push to make it in any way worth a small gain
Bit like PBO in a way lol
I am just curious how high my ram can clock to.
I plan on over locking my CPU next once I finish fclk and final primaries. Does 7950x3D also have that 200mhz limitation?
64GB will be the limiting factor in your RAM speed. You'll hit the memory controller limit before you hit the die limit.
You can't overclock X3D, you can only use curve optimizer.
X3D I can use PBO and CO right?
If it's anything like mine, you'll probably have zero headroom on the vcache chip
Can, not much point to it tho
I just can't mess with voltages like I did on my 5700G right?
I enjoy the tuning process.
I can see that since you've spent like a week or two on what I spent a day 
xD yes
Hoping when I get back home that my ram passed PCBdestroyer.
I am reading about 7950x3D over locking and noticed is it really abnormal that my CPU stays around low to mid 70c during load?
Every article I am reading shows their cpus hitting 89c under load at stock.
Oh custom loop?
Yes
How's the maintenance on a custom loop and when you move the PC do you need to take the whole thing apart?
Custom loops seem super fun to me cause I can picture all kinds of layouts.
I don't need to take it apart
It's heavy af for basically no benefit
If I didn't already have the loop I'd be on air cooling now
Maintenance is 6 months to a year but depends on a lot of factors
What would some of the big factors be?
Weight isn't a big issue for me, I am used to moving my 60lb PC everywhere I move.
Custom loop because you want to, not because you need to
Are you running maxed negative co?
Just got home to check my TM5 run and these timings passed PCB-Destroyer!
Just need to tune tWR and FCLK and I'm finished for ram.
If you're asking me, then no. I have not tuned my CPU yet, that's next in line though.
I would sure hope so at 1.6 vdimm lol. You don't need nearly that much
xD, the jump from 1.5 to 1.6v made a decent difference for me.
Do you by any chance know if it's fine to leave VDDIO and VDDQ at 1.6v? My mobo sets those equal to Dram voltage by default. I'm running likely Hynix A.
my temps are 48-52c during long stress tests.
He has a fan over it at least so it's at about 50-52C
You are right though, 500 sounds more like M die
It’s safe ik but I feel 1.6V is still high for his frequency and timings
We've tried to convey that to him before
Ahh
tRFC refused to boot at 450.
And yeah my ram peaks at about 52c with PCBdestroyer and is usually in the mid 30s to low 40s
400 is pretty common for A die so it very well could be M die
Which is still good
A is better technically but both are more than enough for AMD
Even Samsung would be good enough for AMD really, but not as good for the future carrying it forward once DDR5-7200 becomes a common jedec standard that everything can run
The benefit of A/M die is it can hit 8000 on common sticks, but it's not stable on many current memory controllers
Probably not on your current CPU
There might be one or 2 timings you can get down but nothing significant
what are those?
tWTRL and tWR possibly
I already tuned tWTRL, only timings left are tWR and tRFC2/SB
Those last 2 you can ignore on AMD, they're not used
My new stable timings.
- tWR dropped to 66 from 90.
- FCLK upped to 2200
I will try FCLK 2300 later today.
I forgot, what does that symbol mean again?
does not equal, does not mean, is not the same as
How do I check for FCLK performance?
Thanks.
FCLK 2200 definitely was not 100% stable, I had a idle crash.
If it's crashing then you're way above where you should be. Normally it'll just silently correct the errors, losing a little performance in the process.
Just incase it was tWR I've returned fCLK to 2000 and ran multiple rounds of pcbdestroyer, it was definitely fclk.
Im thinking about overclocking my ram since it seems like free performance, I guess. It doesn’t look like much of a boost from what I’ve seen but why not
I have 3200 dimms right now. I don’t remember my timings completely but I think its 16-18-18-something
Gotta check later
I dont think my performance increase will be that large because I am not using a high end gpu pushing out really high frame rates
Odds are pretty high that you have a C die kit with those specs, so your overclocking options will be limited but there's still a few things you can tighten on subs, if you're lucky you can get it to 3600 18-20-20.
If you have Hynix CJR - check the ddr4 guide in the pins #overclocking message
I was thinking about going to 3600 with timings similar to that too

I will check now
I dont know who makes that kit, but all I can find is sk hynix in software. All I know is sk hynix, micron and samsung b-die
What software are you looking at?
There was a program I dont remember the name of that I am looking for but I used cpuz and just downloaded some pcmark thing 
Was it thaiphoon burner?
The program im trying to remember even showed theoretical configs you should be able to run at
Not sure, maybe
Well if the CPU-Z SPD tab says "Hynix" by DRAM Manuf. I'd be inclined to guess you have CJR, aka H8C
So you can follow the DDR4 guide with that in mind when you get to the timings
Ok burner is showing A-die under the die density
Sure
Thaiphoon really only guesses at it. It said my Samsung C die kit was B die 
It is good for finding the manufacturer at least

Do you know the brand of memory the sticks are from? After double checking, AFR could be possible but that's a very old die.
If it's g.skill or corsair there's a code on the label that will tell you exactly what it is
Patriot too, to a lesser extent
If you're not sure you can find that in CPU-Z too, it's the "Module Manuf."
I have some 5 year old g.skill trident sticks
During the ram shortage of that time
Perfect, there's a code starting with 042 or 043 on the label. The last 5 digits of that code tell you exactly what they used. You might need to take out a stick to get at it.
Yeah thats a thing I can only find by taking it out
Last 5 are 8820C
Yeah that's AFR which is not good for overclocking.
Brutal
That doesn't mean you shouldn't try, you can always tighten timings even if it's not likely to go above 3200
You can start with the "safe" timings in the guide
Yet typhoon said it was hynix a die

Oh is afr and a die the same thing?
Yes different naming schemes but same die
It's not really common knowledge even among an average overclocker so it's fine
Alr. About degradation, how long does ram typically last when not touched? These sticks I have are going towards 6 years
Just don't take it above what's suggested
Work with an even lower voltage limit if you want to be sure
True, im just curious
Well when someone says observed degradation it's probably a few months or a bit longer in the case of the internet

Brutal dyno pill
There are a lot of secondary timings. Do I have to worry about any of these or am I good focusing on the 4 main timings
We bouta find out

Ima test this with the testmem version you guys linked
I ran it for 3 minutes at 3600 18-20-20-40 with no errors
Now I wanna try 3600 but with the old timings. Ima run it for longer to see if it crashes or something
2 immediate errors
The 4 main don't do much
Seconds and terts do a lot
I went from 3200 16-18-18-38 to 3600 18–20-20-40 at the same voltage. I think ima leave it for now because I dont know much about this

It's the whole reason XMP doesn't really matter much in a lot of cases unless the frequency difference (MHz/MT.s) is huge
im having frame drops so ima leave it on default and take the L
You'd think that but according to the ddr4 overclocking wiki 8820C is AFR. Granted there's only 2 entries and they're guesses based on SPD so it could be wrong, but that's the only AFR on the table.
I used the guide lol
C is the revision
thaiphoon absolutely reads cjr as afr
there's no way in hell 8gbit afr is even posting 4500mts
But what if it tried really really hard...
It would get an A for effort and a C for lying about it.
Okay, that was odd. I had a random crash earlier, turned tWR up to 72 and been running same stuff for a few hours, no crashes thus far.
Does HWinfi read dram bus read/write in MB or Mb?
mvm
No necessarily depends on the die
Increasing voltage can be an awful idea they may be on the max of what is safe for their die currently
Can ram overclocking go any amount over what the motherboard is listed to be capable of? and is it good to have a buffer of the motherboard's stated ram speed limit over the overclocking target speed?
What can I get up to with this ram kit, this CPU, and this motherboard?

I wouldn't know
It's early z690 with 64gb of A die
Better than xmp but not sure how much, it would vary board to board
6800+?
6600-6800 prolly
And I think you said going over 6800 wasn't worth it?
It starts to get unstable above that
Random errors and blue screens for no apparent reason, but it passes every memory test except for the week long test that it gets one error 5 days in
Bruhhhh that's to long
That error could of been cosmic rays
No other explanation existed for that result. 7200 - error. 6800 - pass the 7 day test.
And it is repeatable
^
Doubt, daily stable? I’d say 6400 at best
6600 was kinda doable and 6400 still was hit or miss with a lot of voltage tuning on my 2x32 A-die with a Z790
Is it possible for 1.6v on Hynix A or M die to cause my ram to degrade to the point where XMP requires extra voltage to work within a week?
My pc has been having some random crashes here and there so I am trying to figure out what might be the cause.
Crashes never happen during gaming even on the infamous game ark. I notice it during browsing on Chrome or when using Curseforge launcher.
Yeah but yours was gigacope 
1.6 is definitely high and unnecessary for your 6400 tune
That said, degrade? I don't think so
I'd say crashes and bsods slowly occuring is a strong sign your tune isn't stable
Like the slow creep in of a corrupted windows install basically
Been there, done that, many years ago 💀
That same gigacope board can do 7800MT/s daily stable on 2x16
That's not translating very well
It should do better on 2x32
The gap isn't that huge
Is it possible Chrome and Curseforge got currupted on my end?
Cause that tune I did was completely stable on everything except Curseforge and Chrome and when I changed everything back to XMP I was still experiencing issues with specifically those two apps.
What did you stress test with
PCBdestroyer and whatever that other one you guys recommend for TM5 was called.
Passed multiple rounds of both.
TM5 with PCBdestroyer and Anta Extreme profile. I had done multiple rounds of both back to back without issue.
Did you do a large test like vst?
what is VST?
Y cruncher
Is it free? If so, I will test that out.
Yes
I am also gonna reinstall chrome and curseforge before hand on my current XMP profile with slightly extra voltage just to see if corruption is the issue.
Also try this
Or also set power supply to "typical current idle" in bios
Those are a couple potential fixes for idle/low power state crashes
Otherwise, I'd go back and start dialling back the ram tune imo
Run xmp for a few days for example and see if the crashes still occur
If they do try reinstall windows and see if it's better again
if so
The tune was unstable
Or rather, even if they don't occur anymore then the answer would be the tune was unstable still
Hmm okay.
just reinstalled chrome and curseforge, updating gpu drivers while I am at it.
well so far so good.
reverted back to old settings after reinstalling and so far no crashes within the first like 10m of browsing
vst in the pins
Definitely not stable if that’s all you tested with
Is it better to have a higher limit on ram from the motherboard than you need?
I mean, not really but it also doesn't necessarily mean you should max it out
Like b550s support 4400mhz but no way you should try it
I was thinking more like going up to 6400 on a 7800 board
Is that preferrable to going up to 6400 on a 6400 board? (I don't know if a board with that exact limit exists, this is for sake of argument)
Since re-installing chrome I have not had any crashes so far.
Beginning to think the problem was that chrome had become corrupted during the testing phases earlier on.
6400 on current AMD chips may or may not work without desynchronized UCLK. If it does work, unless you're very lucky it will require manual tuning.
Don't desync if you can avoid it. 6000 is generally considered the "safe" spot on AMD that most chips can run with little effort on your part.
You can overcome the latency penalty you get, but you need to get a very high end board to do it by getting the memory above 8000.
What about Intel?
Intel can do in the 7000s and beyond fairly consistently
Well 13th-14th gen, I can't say that for certain with 12th gen
Usually means better compatibility yes but there are way more factors than just that one number
Go on...
What cpu you have, what mobo, what ram costs, if you're ram tuning, a lot
Intel can get weird instability at extremely high speeds. Exactly what point varies by CPU, motherboard, and pure luck in the silicon lottery. The point of instability is usually 7000-7400 but I have seen cases where 7600 was perfectly stable long term.
When I say instability here, I mean random errors and blue screens. You can still pass benchmarks and many stability tests, unless you get that one random error.
I have

Get an a die kit and you could likely easily do 7000, I dont know what timings. I dont know A die tuning at all
cpu imc, motherboard trace signal quality, ram quality, motherboard training algorithms, bios version, mounting pressure, cooling capability, cosmic rays, alignment of the planets
etc etc
I don't know about "easily," a fair bit of luck is involved for it to be considered easy as xmp. Lots of tuning and voltage tweaking is often required. 12th gen is also weird in that it's very particular about what is stable and what isn't when you're running on the edge.
I assume it's similar on 13/14th since Intel didn't change the memory controller much, just the motherboards got better generally.
to 2nd this, I just had a cyberpower prebuilt come in with a 13900k, asus tuf z790 and 7200c34 gskills, and it was instantly unstable in occt mem
3rd this, I’m running Teamgroup 7200c34 2x24 on my 13900k, Z790 Aorus Master on auto voltages and everything and perfectly stable
A whole lotta luck on high freq XMPs
I'm absolutely sure you guys get this along. I am upgrading to 14900k and 7200mhz memory. On cpu specs online it says its limited to 5600mhz ddr5
Is this accurate?
That's the rated jedec
I.e the base speed it's validated up to
14900K should be able to do well north of 7200
with the right motherboard
*and ram capacity
32gb 7200 (2 x 16) nzxt n7 z790
I have no idea how good that n7 is but it's asrock derivative and a 4 dimmer so I'd say good luck for trying to get 7200
The outlook is bleak
Yeah I'd try like 6800
Nzxt lga1700 mobos have not historically been good for ram tuning
I don't need full speed 🙂
Dude at the pc shop said i could get it to 7200 but I saw the online info so I got scared
But I get you
I took it in cos my old 11900kf wasn't working properly with my 4080. Crazy bottleneck.
Believable
Showed him my upgrade plan and he said it should work
Is this just for gaming
And music production and editing
Was saying performance was awful and I got the same fps as my 3060 and 11600k. Old cooler new thermal paste
Temps don't go above 65
What cooler is it
H-
H?
Ok can I make a couple suggestions
Yup
I want a 360mm one but I'm stuck on 240for now
@granite canyon https://pcpartpicker.com/list/sZtJqR
Part List
I would suggest these options
The ram you can swap in, clock up
Or change to a nicer board, one I could ascertain 7200
Sick the. My ram is g skill trident z5
Cos it's corsair? Lmao
OK OK cool thanks
But thermalright works? I might just get kraken 360
Kraken uses a new asetek pump but it's so expensive for very little benefit
The thermalright should hit 98% of your requisite for $55
Go get an old phone out with a usb cable
And install "superdisplay"
Wire it into your case
Full blown screen for a couple $
Much better than a tiny little aio lcd
Lmao. May just buy an old smart watch and 3d print a housing
Those you pay too much for
If you want "better" go ek 360 at $100-110
But the thermalright edge is plenty
Hey that's a great idea
I'll remember that
Keep us updated on it
I would love to see it work
Sure
To ask
Gonna be doing a bunch of cool stuff using lcd and watch quartzes. Some motors too (haptic knobs for software control)
As soon as I'm set up with oc
Pc
anyone know what die this is?
All I can tell is it's 3200c16 so it could be just about anything
Unlikely to be anything too amazing
I don't know how to read hyperx codes either unfortunately
If it's c die stick to 1.35v and no more
C die can degrade above that iirc
If you mean
samsung c die
Ok
Might be Hynix but I’m not sure
Thaiphoon burner said Samsung but when I search my ram stick online it says Hynix
Thaiphoon reads the SPD data off the stick so the manufacturer's usually correct. It guesses on the die.
Thaiphoon is often hilariously incorrect
Ye if you can read the spd then that would be right
Manus often change their supplier
You can double check with cpu-z
Cpu-z I'd trust more
It wouldn't be the first time they used multiple different dies in the same model of stick
Especially something as generic as 3200c16 which could be almost anything
I've even seen the most cursed stick ever. 3200c16 Corsair B-die. The worst bin B-die I've ever seen on the worst PCB.
We witnessed this together
It ran like c die
Corsair lpx 5.31
Or was it 4.31
It was def a b die
Either way it refused to go above 3600

4.31 is B die
Was it you that had the Corsair 3200c16 B-die
Believe so
Well it's gone down in legend at this point
I was wondering why I was pinged in a server I was dead in
I still have them mainly because I can't get myself to buy better ram
Corsair also does some funny stuff with DDR5 too
Cutdown H16A 
At least the PCB isn't awful like DDR4
They probably dug them out of the reject bin like they've always done, and just chopped off the bad part
True, the XMP was like 5600c36 iirc
Been a few days since reinstalling curseforge and chrome. Since then I've had no issues on my OC.
Software was definitely corrupted I think from the unstable OCs haha.
Welp, as much as I hate to say it I think my Windows might be corrupted.... Reverted back to XMP and still getting rare once in a blue moon crashes,
If everything is running stock (XMP) and I still experience crashes now and then completely randomly is it safe to assume my windows likely got corrupted during the period where I was overclocking?
Generally you don't use your main OS for overclocking for this reason
Think it's likely a windows corruption then?
Worst case I don't keep anything important on my boot drive so I am just trying to figure out what the issue is then the solution.
Gonna leave my pc on overnight to see if it crashes cause when it crashed, both times one thing that was consistent is that I had the CurseForge launcher open vs all the time that I didn't have it open and my pc was just fine.
It's entirely possible that reinstalling windows will fix it
But narrowing down common factors is good too
cursegorge and proton vpn have been common factors
i think i will just do this tomorrow to wipe out a long list of possible issues
Left the pc on overnight, no crashes.
gonna reinstall windows.
Run the highest frequency you can with the tightest timings, benchmark, then compare between the different combinations to see which performs best.
I'd do at least 5 runs on each freq/timing combination of your choice to get an average to compare with.
C die usually caps at about 3600
Run it with 1.35v or less to avoid degradation
If you can see higher, play with it, but posting ≠ stable
P95 large or small
Mmm.... I'd still do a bit of a proper test
VST is pretty solid
Ye
I've heard of vram+large before
Though I don't use it myself, feels more like a more outward test than something I would consider to be direct
Tools I use are tm5 for am4 especially
Vst
FFT*
Occt large
Occt vram I'd use more for a gpu lol
Tm5 anta777 is really good
Absolut too
Tm5 I would make the case has been historically the most thorough for am5
Play with 3733 and 3800 tho, test them on a dummy windows
If they work that's an impressive result for c die
Higher freq. Is the most linear uptick for AM4 due to fclk sync
But yeah you should test each, sometimes you can be stable on a higher frequency but less fast
That’s not specifically for ram, that’s testing your fclk for stability
Actually testing ram for stability you’re looking for ycruncher FFTs and VST, TM5 PCBD and Anta777Extreme and OCCT mem test
Oh it was fft's I was trying to think of
Not vtt
I knew there was a second test I just can never remember the name
if you want to be really rigorous with your testing you can run occt 3d alongside ram tests so your gpu is dumping heat into your case
not sure how heat sensitive c-die is though
It's not because it'll rarely be above 1.35v
Has anyone run into the issue where they cant undervolt in Intel Extreme Tuning Utility even after turning on the microcode selection on MSI bios? Im running the one from january 2024 on an MSI MEG Z690 Unify
@misty socket what cpu
Use bios
I7-14700K
