Re: Ryzen 5800x system crashing into reboot while under gaming loads unless 2 cores are disabled

Unfortunately, I've tried disabling Core performance boost and have not achieved stability

Re: Ryzen 5800x system crashing into reboot while under gaming loads unless 2 cores are disabled

I have tried this and it does not solve my particular problem... the only stable solution remains to run the processor at 6 cores only unfortunately. Disabling Core performance boost does not help in my case.

Re: Ryzen 5800x system crashing into reboot while under gaming loads unless 2 cores are disabled

Is there anyone having this issue on a different motherboard brand? Everyone I have seen having a problem is on a gigabyte board

Re: Ryzen 5800x system crashing into reboot while under gaming loads unless 2 cores are disabled

Yes. I have a 5900x on an ASUS ROG Strix X570-e and having the same WHEA BSODs and self-reboots. 
I never have them under load but only AFTER a heavy load. Like I stopped a game or a burn-in and in several seconds there is a BSOD. 
Sometimes (seldom) it can happen 2-5 seconds after starting a game.

And yes, CBP disable helped. But of course I really hope for a normal solution from AMD and/or ASUS. Using the brand new CPU at half power is frustrating.

Re: Ryzen 5800x system crashing into reboot while under gaming loads unless 2 cores are disabled

Hey Tim, any chance of being able to see what the voltage is doing when it is coming off of a heavy load? It sounds like it’s undervolting aggressively when coming off boost and causing the system to become unstable.

Hey! 

If you can tell me the utility to use (will AIDA64 do?) and which voltages to check then I can check this.

If you can consistently reproduce the crash in aida64 that will be perfect. Watch the voltage across all cores and see if any dip below 1.04 or go above 1.4 when the crash happens

Re: Ryzen 5800x system crashing into reboot while under gaming loads unless 2 cores are disabled

Hmm...Thank you that you made me look there. 
I didn’t even have to reproduce the crash. I see only one core voltage parameter. But in idle it jumps from 0.2v (!!!) to 1.0v, sometimes even up to 1.4 for a moment. Under all cores burn in the voltage is steady 1.0v +-0.02.

PBO And Core Boost are off, so this is even with stable system settings. 
I can reproduce the crash turning Core Boost to auto, but what the sense if the voltage jumps like crazy even now?

What is this crap and is it possible to do something about it?
