Posted January 29, 2021 Hi all, I'm trying to diagnose some random crashes I've been experiencing with my new PC. They happen out of nowhere, once every few hours, mostly at idle or light use, and require a hard reset of the PSU switch to fix. The screen suddenly goes black, no IO, power/reset buttons don't work, motherboard Q-Code says "00" - ROG Crosshair 8 Dark Hero - 5950x - Reference 6900XT - 64GB Quad-stick DDR4 - Sabrent Rocket 4 - AX1500i new/refurbished. What causes this type of crash? 1. My first thought was PSU since I felt that it might've been an interruption in DC power. I pulled out the AX1500i, disconnected everything, and the self-test turns green and fan spins if I hold the self-test button down for ~0.5s. If i just tap the self-test button, nothing happens, is that normal? 2. My main question: Is a bad memory OC/bad RAM known to cause this type of crash? I've always associated bad RAM with random BSODs and refusal to boot, but this thing boots without a hitch and has never BSOD'd on me except that one time I went wayyy too unstable on the ram-OC and it BSOD'd on boot. It crashes the same way every time as described above, prolly 5-6 times now. The RAM has passed overnight memtest86 twice now (4-pass runs), even with an beyond-XMP OC. For now, I've removed even XMP, and am just testing at pure stock 2666MHz 20-19-19-43 with a brand new HX850i. 3. Motherboard? Ugh that would be a PITA. 4. GPU drivers? It's a new install, but I haven't ruled it out yet.

Posted January 29, 2021 What bios version are you using? But yes a bad oc could do this.

Posted January 29, 2021 Author @DoctorNickNewest v3202. And yup, stock RAM hasn't crashed on me yet, but it's only been a few hours and the crashes happen randomly, so I'll keep an eye on it for the next few days. I did change 2 variables at once (HX850i + Stock RAM), so if I don't get any more crashes i'll try stock RAM+put my AX1500i back in. The few similar cases I could find pointed in all sorts of directions, with some claiming new RAM fixed it, others concluding a faulty CPU, and some pointing to the Mobo since the power/reset buttons no longer worked. Everything's new on this system so I have no idea at this point. The only known good I can test with it is my old RM1000 PSU.

Posted January 29, 2021 Author wow what dumb, unfortunate luck. I updated the BIOS the day i got the motherboard, downloading the version marked "3204" from asus' website. Turns out someone fumbled the file upload and uploaded the unstable beta bios 3202 instead to their website. 3202 doesn't even exist on their website! Now i've gone back and reupgraded to the proper 3204 BIOS. Here's to hoping that this solves all my random black screens! fingers crossed.

More importantly, 3204 still needs to prove to me that it's the solution to my woes.

Posted February 15, 2021 Author Aight, final update: disabling global C-states in the 3204 bios fixed it. 3204 out of the box was noticeably more stable compared to 3202, but still crashed on me a few times. Hypothesis: with C-states enabled, when the system is at low load or idle, the CPU aggressively undervolts the CPU to the point where one of the CCD's becomes unstable (since 5950x's all have one good-binned CCX and one poorer/average binned CCX -1usmus), hence explaining why the system only crashed at low load/idle and never under load. Disabling C-states has fixed the issue, or so it seems, after going through 2 weeks of not having a single crash. memory OC has been put back in place too with no issues so far.
