PC won't wake from sleep - random restarts without BSOD in some games

[More Sly]

It's possible this worked. I saw a little barely perceptible screen flickering, but no restarts so far. Yesterday restarts were already pretty infrequent, though, so I'll have to test a lot longer.

After a few more nights of testing, I'm fairly confident this fixed the problem - but I'll come back if it shows up again. Guess my CPU wasn't getting enough power? Thanks for the tip! @Braegnok

Hey folks, I have an issue I've posted about previously that's ongoing and I'd like some advice if anyone's willing.

After installing a and Ryzen 7 5800x and B550 Aorus Elite V2 in August with a fresh Windows 11 install, my computer was unable to wake from sleep. On wake, the fans spin at what sounds like 100% but it never actually wake up. If I force a shutdown and start it back up manually it restarts as if waking. I've been in touch with Gigabyte's support and am slowly troubleshooting, but I just disabled sleep and figured I'd deal with it slowly. I've reset my BIOS with the B550's CLR_BIOS pins and tried a new installation of windows on a new drive - the issue persists. Next step is flashing to the new 15d firmware (I'm currently on 15c).

But another issue has come up and I'm not sure if it's related. In some games I'm getting random restarts. No BSOD, just a sudden restart and a kernel power error in the events log. This has consistently occurred in one game (Oxygen Not Included) but has only ever happened once in one other game (No Man's Sky).

My biggest suspicion is still that this is a faulty board with power delivery issues, but I'm exploring other options before I can RMA. The restart issue lessened when in-game actions in ONI reduced the memory load, so I wonder if this might be a RAM compatibility problem - I have 2x8 GB G.Skill DDR4-3000 DIMM CL16-18-18-38. BIOS reports both sticks running at 2133 MHz and enabling XMP gives me pretty much immediate BSODs.

I'm also wondering if this could be considered erratic CPU behavior? CPU stress tests don't cause the issue - I've run 3DMark and Cinebench with no problems - and I think this is probably just a little residual paranoia about installing an AM4 CPU since it was my first time plugging in a PGA chip. I've had a bit of high heat in very CPU intensive games where it's had odd peaks at 91 °C, but it was otherwise stable in safe ranges with an average temperature around the mid 60's to maybe 70 ° during long sessions.

I've attached a HWiNFO log leading up to one of the restarts in case that might suggest anything, the event log, DxDiag, and a log file from ONI (just in case). Any thoughts would be greatly appreciated!

Either your curve optimiser is too low or your SoC voltage is too low for your IF frequency (memory controller/ram speed)

You've got RAM that SHOULD be easy to run, but that doesnt mean weird shit cant happen
Turn XMP on, but chance the SoC voltage to 1.15v and see how it goes

SoC crashes can take out PCI-E, SATA, USB, or memory controller resulting in some seemingly unrelated errors like the USB disconnects, black screen freezes, reboots, etc etc etc

"I've had a bit of high heat in very CPU intensive games where it's had odd peaks at 91 °C"
that's the problem, or part of it - my memory controller gets less stable past 80, and it should be thermal throttling before 91
Higher SoC voltage increases the stability AND the temperatures, so it's not the perfect answer here - you need that cooling fixed too

Well, the issue is certainly less frequent but not gone. New RAM in running with XMP on now, too.

I'll check out the SoC voltage @Mussels, thank you. Think I'm at the point where I'm RMAing this mobo. The heat issue is dealt with since I'm still breadboarded - not running so hot. I've got a HWiNFO spreadsheet here with the last recorded behavior until a restart.
