I think its a power delivery issue, cpu doesnt have time to heat up, the clocks drop the instant you start the load and come back up once the load is stopped. I've tried reinstalling windows completely and resetting to default settings

[mental briar]

Someone please help with this, haven't been able to figure it out for months

[astral elm]

and you've been using it like that for months?

btw does it do the same when not 100% used?

idk like 80%

[mental briar]

no

only at full loads like cinebench and 3dmark

[astral elm]

so only 100%?

okay

did you update bios?

[mental briar]

bios is new

[astral elm]

good

[mental briar]

i can take a video of it

[astral elm]

sure

does it only do it when stresstesting or while playing games as well

[mental briar]

games are fine

bios settings are all stock, just did a fresh install of win 11, was windows 10 before, same issue

all drivers are up to date

[astral elm]

so if it runs games perfectly under 100% load

[mental briar]

no games ever hit 100% load

[astral elm]

does it?

hmmm

thats weird problem

did you overclock cpu?

[mental briar]

no

bios is stock

[astral elm]

ok

[mental briar]

also power repoort deviation is insane

236% max

[astral elm]

yeah its running perfectly

[mental briar]

wdym

[astral elm]

oh nvm

some cored are 500 mhz

[mental briar]

yeah

[astral elm]

cores*

weird

i'll get home and try solving this

[mental briar]

how long do you think youll be?

[astral elm]

like 20-25 minutes

[mental briar]

ok

[astral elm]

maybe someone else will help

oh and

check how much power is your cpu getting

[mental briar]

PPT?

[astral elm]

also did it start happening randomly?

[mental briar]

no

upgraded my cpu from 3700x

started then

[astral elm]

hmmmmm

[mental briar]

PPT is 76 W

[astral elm]

how much watt does your cpu use?

like the max

[astral elm]

under 100% load?

[mental briar]

yes

[astral elm]

ok

[mental briar]

with these clock issues

[astral elm]

yeah yeah

its max is 105

its ryzen 9 right?

[mental briar]

ryzen 9 5950x

[astral elm]

105 watts

and its only using 75

[mental briar]

its base clock is 3.6 not 3.4

[astral elm]

does the motherboard really supplies 105 watts to the cpu?

[mental briar]

105 is TDP

[mental briar]

wdum

[astral elm]

uh

3.4 is base

[mental briar]

ah i was wrong

[astral elm]

?

[mental briar]

i thought it was 3.6

[astral elm]

hat

what*

[mental briar]

yea but not dropping them to .5 ghz lol

[astral elm]

reasonable

[earnest bolt]

If it’s boosting down to 500mhz there’s 2 reasons. 1 I can’t remember but it’s a settings issue, the other is severe thermal throttling

Remedy is you’re severely thermal throttled or probably a full windows reinstall iirc

[mental briar]

its not thermal throttling and i just reinstalled windows

[earnest bolt]

I’ve seen before switch cpu and their aio busts a couple of times this year

What’s your temps when it’s 500mhz?

[mental briar]

44 C

[earnest bolt]

lol what

Full load 44c?

[mental briar]

^

yea because its not drawing any power because the clocks r .5 ghz

[earnest bolt]

Have you ever under volted either cpu

[mental briar]

all bios settings are completely default

[earnest bolt]

Max thrrads 100 cpu core usage 22

That’s your issue

[mental briar]

what

oh in hwinfo?

[earnest bolt]

Can you check vrm temps?

On your board

[mental briar]

50 C

[earnest bolt]

Performance power plan set to allow 100% all the time?

[mental briar]

was on balanced

just switched, didnt fix

[earnest bolt]

Put it performance

And what’s your soc on your ram? And is it set to docp

[mental briar]

idk what that means

the pc was exactly the same before i switched cpus tho, ever since i switched from 3700x to this one ive had this issue

[earnest bolt]

Well you need to set xmp/docp back on jn the bios

[mental briar]

xmp is on

[earnest bolt]

You also need to in hwinfo let us know what ram voltage is

So the soc

That can throttle

[mental briar]

Soc Voltage ( SVi2 tfn)?

[earnest bolt]

Threads I see suggest stock 1.25v set by mobo on AM4 throttles

Should be around 1.4 to 1.45

After that i am not sure where you can go if it’s around that. If not need to manually adjust in bios

And xmp must be on or it just won’t load your ram (likely)

[mental briar]

xmp is on

it says soc voltage is 1.081 V

[hasty mirage]

Did you change cpu lately?..

[astral elm]

he did

from 3700x to 5950x

[hasty mirage]

Did he install windows?..after changing cpu?..

[astral elm]

yes he reinstalled

windows

[hasty mirage]

Using a usb stick?..

[astral elm]

idk

that

[hasty mirage]

Wiped the drive?..

[astral elm]

only he can tell

is it an issue?

[hasty mirage]

I am thinking...the previous settings for the old cpu..in the windows or in bios may have affected the new cpu...

[astral elm]

he said bios is stock

so he probably did a usb install

also bios are up to date

[hasty mirage]

Needs a confirmation from him...

[astral elm]

yeah

thats why i said probably

just a guess

[hasty mirage]

a desktop cpu can only switch to low clocks if..the power plan is messed up or previous oc settings or undervolting settings affected the new cpu...

Other than thermal issue...

I wonder if he is using a debloated os...

[astral elm]

debloated os

like?

[earnest bolt]

Looks bugged out. Check bios output

As 1 is too low

Default should be around 1.25 and xmp 1.4 or 1.45

[astral elm]

yeah

cookie are you stressing both cpu and gpu?

[quaint ledge]

Let me guess, you have a water cooling AIO?

[astral elm]

how could that be a problem

[quaint ledge]

Classical problem with water cooler (primarily AIO), they die, CPU heats up, overheats and downclocks to 0.5 GHz not to cook itself. One of several reasons not to buy any sort of water cooling over good air cooling.

[astral elm]

but he said temps are 44

temps are fine

[quaint ledge]

That's the reason his temps are "low" but frequency stays low

[astral elm]

hmmmmm

well lets see

when he tells us

[quaint ledge]

Since it now runs at so low speed it doesn't heat up enough even if the aio is fucked and simply dissipates though the coolers plate thermal mass alone.

[astral elm]

according to him it slows down when on 100%

not sure if he check temps when the cpu is running on its max

as much as it can

[quaint ledge]

Yes, because it ramps up, overheats, downclocks, cools down and stays there

[astral elm]

hmmmmm

great

[quaint ledge]

Remember kids don't buy aios if you don't want to have random problems like that. 😄

[astral elm]

i think fans are pretty good bruh

not a big fan of water cooling

personally

!!

[quaint ledge]

The only thing AIO is good for is looks, performance is same as good air cooling and unlike air, it can be maintenance heavy and definitely not problem free

[astral elm]

agreed

plus it increases costs

buying best once's available so that you wont regret in the future

[quaint ledge]

Even Noctua D15 is cheaper than many AIOs and will be problem and maintenance free essentially forever.

[vernal hatch]

@mental briar If HWiNFO is running at all times, what is the max temp recorded for the CPU?

[earnest bolt]

He had all cores boosted momentarily to 4.9ghz

Max cpu die temp I can get from the video is 75c as it’s grainy

But it doesn’t thermal throttle like a dead aio would. A dead aio would let your cpu boost to TJ max before throttling

I’ve seen this issue before and various things have solved it. It’s never straight forward

It’s like his cores are parking but he’s never had an x3d chip

Actually… OP did you update motherboard chipset drivers?

[mental briar]

Fully wiped drive did a full clean install, didn’t touch power plan,

[mental briar]

AIO is new, and the temps are fine

[mental briar]

It’s not a thermal issue

[mental briar]

Yes they’re newest version

Sorry guys I went to sleep

[quaint ledge]

Because its new and temps are low doesn´t mean it isn´t DOA or that it isn´t a thermal problem

[mental briar]

It’s fine while gaming

[mental briar]

It’s not a cooling problem, It’s been intermittent at times and I’ve had runs of cinebench going at max load at 70 C and then it starts

Plus if you watch the grainy video you can see that the second I click start on R23 the clocks die, it doesn’t even start the render before they all drop. There’s no temp spike as there’s no time

[quaint ledge]

Let me guess, if you run another bench right after the first one fails, it always "fails" and throttles immediately.

[mental briar]

Yeah, it always does it

[quaint ledge]

Do yourself a favour and save time, go and grab even some basic cooler like Deepcool AK400 and try again

or even a box AMD one

[mental briar]

Brother 🤦‍♂️

It’s fine under high gaming loads

[quaint ledge]

What do you consider "high gaming load"

Because playing COD, Fortnite or whatever AAA fps you are trying isn´t high load for the CPU

[mental briar]

High enough to bring temps up

If my cooler wasn’t working, it doesn’t matter what kind of load it would be it would still thermal throttle

It’s a 360 mm radiator with six fans

[quaint ledge]

That doesn´t foking matter, the plate on the CPU can transfer X amount of heat and the water can take up some amount as well before its too hot to transfer any more out. If you just load CPU lightly, it might not be enough to overwhelm the cooler on the CPU and water would take potentially hours before enough heat would transfer.

GO AND GRAB EVEN A BOX COOLER AND TRY IT FFS.

Its 4 screws

Instead you are gonna spend hours trying software and refusing to admit that AIO can be DOA

[mental briar]

I know how a cpu cooler works, I’m an engineering student I take courses on that shit

[quaint ledge]

Is grabbing a screwdriver and changing a cooler to test it too difficult then?

[mental briar]

I don’t have a second cooler atm, and also the cooler works

I’ll show you

Cold startup

Multi core, temps are good

Second pass

Temp is now 33 C

[quaint ledge]

They are good only because the CPU throttles all they way to 500mhz and generates barely any heat man

[mental briar]

I’m doing single core rn at 5 ghz, 59 C

Actually here let’s do more

Anyways I gotta go to work , if all you’re going to do is try and tell me it’s the cooler when it’s clearly not a thermal problem please stop responding to this thread as it’s not helpful

[quaint ledge]

If you refuse to try things out when everything points in one direction then there is no helping you.

Indulge me, how do you know that the AIO works.

[mental briar]

Also that’s not how heat transfer works. With a dead pump the CPU with throttle very quickly because as the water around the CPU block heats up the energy transfer rate slows down drastically. That is why you need a pump to cycle cold coolant through so that heat actually transfers. The whole water cooling loop does not heat up before your cpu throttles

[mental briar]

Heavy single core loads, gaming temps are fine, temps stay stable in a hot room, I can hear the pump running, and like i said before I’ve had full cb runs with max temp at 72 C

I also see the reported pump speed in bios

Also the thermal throttling indicator in hwinfo stays at no

And the inlet hose on the cpu block is cold, not warm, meaning new water is being cycled through

And another thing, if it were thermal throttling you would hear the fans going crazy trying to cool it down

[earnest bolt]

Apparently bit locker enabled can also cause this

Like I said it’s not an easy one to solve. Many issues can do this

It could also just be the motherboard and the VRMs failing though. It’s where I am hedging my bets

Maybe even knocked the board and a sensor dead when reseating cpu/aio

[mental briar]

I thought it was motherboard vrms but idk how to prove it

[mental briar]

Not sure if I have that, if it’s an app then no but if it’s a windows thing maybe

[mental briar]

I’m always extremely careful when doing stuff like that, obviously nobody’s perfect but I don’t think that’s what happened

[mental briar]

Where can I check this in bios? I’ll check when I’m home from work

[earnest bolt]

Throw your old cpu back in and see if it throttles

Is my best guess

[mental briar]

I sold it unfortunately, but I think it didn’t draw enough power to throttle the vrms, and now that I have a more powerful cpu they can’t keep up

[sharp jacinth]

You could try limiting the tdp of the cpu, and slowly raise it, until it doesnt work anymore.

Just a thought tho

[mental briar]

How do I do that?

Is it in the bios?

[sharp jacinth]

AMD Ryzen Master. Its an app you can use, officially from AMD

[mental briar]

Ah yeah I used to have it, didn’t like it

I’ll try that later tonight

I’m at work for the next eight hours

[sharp jacinth]

Okayyyy

Good luck :)

[mental briar]

Thanks

[mental briar]

where is the setting to limit tdp?

[sharp jacinth]

You can watch a youtube vid for rhat. I dont remeber as I aint have a amd cpu anymoew

[astral elm]

@mental briar are you stress stesing both cpu and gpu?

[mental briar]

No, just cpu

[astral elm]

good

let me thing whats next

think*

[mental briar]

Thanks for the help, I know this is a super weird issue

[astral elm]

well guess what

i am also learning new stuff

its interesting

can you try changing cpu drivers?

idk like just dont use the current one

use 3rd party app to either update them or use some older one

[mental briar]

OK, I’ll do that this evening. I gotta go to work.

Which driver should I use?

[earnest bolt]

You mean motherboard chipset

CPU has no drivers

[astral elm]

yeah ywah

[astral elm]

any except the current one

not sure if it will work or not but worth the try

[mental briar]

Okay I’ll try it

[mental briar]

people on reddit are saying its because of bugged bios or bugged chipset driver

https://www.reddit.com/r/AMDHelp/comments/sea2qf/5950x_at_default_settings_stuck_at_547mhz/

[astral elm]

thats what i said

[earnest bolt]

There’s a lot of reasons this seems to occur. Trying everything, everyone suggests is a good idea.

[mental briar]

Yeah

[mental briar]

I can’t seem to find an older chipset bios to install

Is there an archive website

[astral elm]

you mean chipset drivers?

see idk where to find them

someone said they use iobite to update their drivers, so maybe try that?

ask dethriguez if he knows any better

[mental briar]

Ok
Will do, I shouldn’t ttry to downgrade my bios right

[earnest bolt]

You will be able to get latest drivers through msi center

[mental briar]

I already have the latest drivers, we think they’re bugged and want to try an old version

[astral elm]

anything?
