During my test for at least 4 days seems to be the Asus BoostIt causes the QCode 00. More so the CPU boosting the CPU past 5.7GHz. Also seeing the same with BIOS AI optimization also triggers QCode 00 which pushes the CPU to 5.875 so COD MWII would trigger it.
This error just got even more crazy for me. I'm on a completely new Asus Hero board and new 7950x. I will shutdown my computer at night; then the next morning I'm not able to even power it back on without doing a hard PSU power off.
HI have the exactly issue with my system. I got a 7900x with an x670e Hero and a Gskill 30cl 6000mhz.
I used to use the AI overclocker but I have now stopped to see if it's that. it's not crashed yet but its just really random when it happens. on a separate help page, someone mentioned that it could be the cooler is over-tightened on the socket I have a custom loop with strings for it to have even tension. I hope it helps, but I wish this gets fixed ASAP with a Proper Bios update or something.
I think you might be on to something, I'm currently troubleshooting my own 7950X build. It runs FINE on a test bench with an AIO, but the second I put it in my PC with EK's AM5 Quantum Velocity 2 block it codes 00 when I start a game. I think EK ****ed up and the mounting pressure is too much, going to do some more testing in the coming days. And BTW I have an ASROCK board and not an ASUS, so this problem seems to be across the board leading me to believe EK is to blame.
I have loosen the EK Velocite2 mount and basically it's the thermal compound holding it on the CPU. Set the BIOS to default via F5 and set set the AI OC, BIOS code 00 still happens via gaming after an hour or 2. It's not a tension issue but either CPU or BIOS on the Hero x670e.
It was loosen all the way, I kept a 360 turn on each screw in a cross pattern every time I was getting the Code 00 error. At the end it was completely loose, only the thermal compound was holding the cooler on the CPU.
