Question Prime95 - Instant Failure

[tylerpastorick]

Specs:
13700k
RTX 4080
DDR5 32 Gbs (Ran memtest86 and found no errors)
ROG Strix Z690-E (Just updated bios to latest update)
Windows 11

Decided to run this test as War Thunder keeps crashing, and anti-cheats for 3rd party software (FACEIT anticheat for CS2) is giving an error due to a hardware error.

When I run the Prime86, instantly the "Worker #2" fails. Need advice as to if this means my CPU is cooked, or what should be my next steps. Keep in mind, I am not overclocked, and I attempted to turn on "XMP Profile 1", and then still failed the test.

Thanks for your help,
Tyler

Look in Reliability History/Monitor and Event Viewer.

Either one or both tools may be capturing error codes, warnings, or even informational events just before or at the time of the failures.

Reliability History is much more end user friendly and the timeline presentation may reveal patterns.

Event Viewer requires more time and effort to navigate and to understand.

Take a look at what is being captured in the logs. Any given entry can be clicked for more detailed information. The details may or may not be helpful.

Hey there,

Prime95 puts a tremendous load on the CPU. It is mainly used for checking for absolute stability of a given CPU with a given voltage. It's not indicitive of real world usage in any way. It will run your CPU at max voltage and will keep your CPU pegged at 100c for the duration until it throttles or a core fails.

Did you clear CMOS after the bios update? If not, you will need to do that before testing further.

You can use Cinebench R23 to run a heavy but moderate load to test the CPU. Check what clocks the CPU is hitting whilst it's running. You can use HWInfo to monitor temps.

Hey, thanks for the reply.

I cleared the CMOS and ran the two programs as you said. I am assuming Cinebench doesn't show errors but is more of stress testing?

Clock speeds: https://ibb.co/Y3LFwSH
Temps on HWINFO: https://ibb.co/PWcTwQq (3rd column was max, basically was running in the lower 90s the whole time and hit max 96)

Hey, thanks for the reply.

I have not seen any details in event viewer/ reliability history that seem to be related to the problem, or have occurred when issues have arose as well as the Prime95 test.

Just wanted to add that the failure in Prime95 is always instantly, and is always on Worker #2 if that means anything. Since Faceit anti-cheat is not working due to a "hardware error". I believe it is catching the same error that Prime95 is catching.
