Question PC crashing after CPU upgrade ?

[efbratcher]

I have been slowly upgrading the hardware on my PC over the last few years. This week, I upgraded to CPU from a Ryzen 7 2700X to a Ryzen 9 5950X. I updated the BIOS and chipset drives, and I switched my UEFI settings to CMS.

After upgrading the CPU, and only while playing games, will crash. I get a black screen, and my monitor notates no input and automatically shuts down. All RGB components stay lit, and all fans remain on. My power button becomes unresponsive, even when holding down the button to force a shutdown. The only way to progress is to switch the power off on my PSU. Once I switch that off, give it a moment and turn everything back on, it works fine.

At first, I thought it was a heating issue. I was getting into the 90C range, so I swapped in a new CPU cooler and got temperatures down. Now I game in the 60C range, but I still crash.

When I am watching browsing the web, chilling on discord, watching youtube etc. (anything non-intensive). It all operates fine with no issues. It only crashes when I am playing a game. It doesn't matter which game. Just any game at all. It doesn't crash immediately, either. Sometimes I can get a few hours in. Other times, I get 10 minutes.

Hardware currently installed is:

PSU: Corsair RM850X
GPU: MSI Gaming TRIO GeForce RTX 4070TI
Memory: Corsair Vengeance LPX 16 GB (2 8GB sticks)
MOBO: MSI B450 TOMAHAWK ATX AM4
CPU: AMD Ryzen 9 5950X
STORAGE: 1 500GB SSD, 1 4TB SSD, 1500GB NVME SSD

Welcome to the forums, newcomer!

I switched my UEFI settings to CMS
You should've left it at UEFI, disabling CSM.

PSU: Corsair RM850X
How old is the PSU in your build?

MOBO: MSI B450 TOMAHAWK ATX AM4
BIOS version for your motherboard at this moment of time?

You might want to see if aiming a fan at the VRM area of the motherboard helps prolong the time your system is up.

I initially had it in UEFI, but after installing the new CPU, it would only boot to BIOS. After a quick google search, I found that booting in CSM solved this for a lot of people. It also solved it for me.

PSU was updated last year. I want to say it has about 13-14 months on it, but I can't remember exactly.

BIOS version is E7C02AMS.1I0

Check with OCCT

Check with OCCT

I ran a default stability test for CPU and RAM for an hour with no errors.

 

[efbratcher]

After running a power test for 10 minutes, I got the following error probably 50 times:

Error - 3D Adaptive - 785808 error(s) found ( GPU #0 - NVIDIA GeForce RTX 4070 Ti )

I didn't export the report on accident, but I ran the test for another 10 minutes and got no errors.

hmm gpu is the culprit?

run occt cpu with memory test

run ram only test (maybe ram overheat?)

use unigine superposition for gpu (8k)

the last suspect is your psu, do you have another one to test?

I ran the CPU/Memory test for an hour with no errors.

I ran the 3D adaptive for 10 minutes with no errors.

Ram only test had no errors.

I have my old CPU, but I had no issues with it before I swapped it out. That was 3 days ago.

The superposition benchmark seems to have run fine? I got a score of 6259 when running the 8K optimized option.

thats really unfortunate, have you checked the vrm temp? and others like chipset.. could be a cpu issue, even the psu.. have you oced your system?

 

[efbratcher]

No overclocking anywhere in the system.

I'm not really sure how to check VRM temps. I'm willing to check anything, though.

check your temps like vrm, chipset, and others.
the 5950x is used or new?

 

[efbratcher]

Right now, it appears as if that temp is good. its sitting around 42C.

new CPU is brand new. Only the 3 days in my machine.

well, the other way to test this cpu is to use another mobo.. we need to know if your cpu is bad, do you have your old psu? do you have other ram to test?
try to use cpu warranty. its always best to have another pc components to test such things.

I have other components I can swap out from upgrading hardware over the years. I do not have a spare MOBO or PSU, though.

I played a game to the point of crashing. I monitored VRM temps the entire time. I didn't see any temps higher than 64C. It sat around 60-63C for the majority of the time.

 

[Eugene$$]

then its probably a cpu.

As in, the specific unit I purchased is bad? Or the CPU is not compatible with my rig?

the cpu is compatible, try newer bios maybe, since you dont have other mobo to test i cannot help you more.

try ram at stock without xmp.

BIOS version is E7C02AMS.1I0 which is the newest version.

RAM is running without XMP. It is DDR4, but I have also set it to run that way in BIOS.

I think I am going to put my old CPU back in and see if I can use warranty for new CPU

CPU is fine these CPUs do not play nice on air cooling.

I find if you undervolt the CPU and turn of the turbo boost function on the motherboard that the system is stable.

Memory at 3200 2 sticks is fine 3000 if 4 sticks.

It's probly still overheating because these chips keep battering that 1.5v ceiling

Monitoring software won't see both chips there are 2 chips under the CPU die and hwmonitor shows both. On mine one cc'd is 10c hotter then the other usually.

Even if your monitoring it in game it only needs to spike for a few minutes to shut off or hit a area where the CPU is being pushed hard.

I've not had any problems running a similar 7950X on air cooling in an old Lian Li case (circa 2006) with limited ventilation (2 x 120mm intake fans, 1 x 120mm + 1 x 80mm exhaust). The CPU sits at 170 to 190W for up to 36 hours on long 4K/UHD video renders with no system crashes. CPU temperatures stay in the mid-eighties (Centigrade) for many hours and peak at 92°C. I built this system in December 2022.

MInd you, I am using an X670E motherboard and not a B450, so the VRMs might be stronger. I'm not overclocking my 2 x 32GB Kingston DDR5 RAM on the 7950X (4800MT/s) but I do have a mild overclock on the 4 x 16GB Corsair Vengeance DDR4 in my 3800X (3000MT/s) and it's rock solid too. MemTest86 checks out fine on both rigs.

After running a power test for 10 minutes, I got the following error probably 50 times:

Error - 3D Adaptive - 785808 error(s) found ( GPU #0 - NVIDIA GeForce RTX 4070 Ti )

I'm running NVidia's Studio driver on the RTX 3060 in my 3800X rig and the RTX 4070 in my 7950X rig. In theory the Studio driver is more stable than the Game driver, but it might not cope with the latest games, or the FPS might be lower.

It might be an idea to uninstall all video drivers with DuD and reinstall a stable driver.

PSU: Corsair RM850X

I have an RM850x in my 7950X rig plus an RM750x in my 3800X rig and I've not seen more than 430W power consumption during long video renders (7950X/4070 system) so there's plenty of headroom.

CPU: AMD Ryzen 9 5950X

The 5950X will pull more power than the 2700X and if the new CPU is OK, it might indicate a problem with your RM850x, but at only 13 to 14 months old, it should carry on working for years.

With this type of problem, apart from installing a fresh copy of Windows on a spare drive, the next thing I'd do is swap components. This can soon get expensive with no guarantee of success.

A good real-world test for the CPU is a Handbrake video conversion, with GPU support disabled. You could also try WinZIp or WinRAR and archive a large folder full of files. If the GPU is not doing anything and the CPU remains stable under heavy loads, the CPU and VRMs are probably OK.

I don't run "artificial" stress tests for long periods because to my mind, they're not entirely representative of my normal loads. I run Prime95, AIDA64, FurMark, plus a few other tests on a new system, but not for more than 30 minutes.

7000 series is designed up to 100c the 5900x and up sweat when it hits 91c they turn off 3800x is 1 CPU die of 8 so it's fine on air cooling it's not great when multiple dies are under a air cooler it's like cooling 2 CPUs on one cooler.

Same with 2700x being a single ccd cpu die
