I’ve swapped a CPU going from 5600g to 5900x, unfortunately the system seems to bluescreen from time to time (usually takes hours in-game, otherwise stable)

For some reason it gets slightly worse when I enable XMP. Significantly worse if I undervold the CPU even a bit. Temps go no further than 80-85C under full load.

Would appreciate your thoughts on potential reasons.

Specs:

  • 5900x
  • B550m DS3H (Swapping tomorrow to B550 Tomahawk)
  • 3600Mhz 2x16Gb Kingston Fury (2400mhz if JEDEC)
  • 6700xt Saphire Pulse
  • 750W Zalman GigaMax

Will also be reinstalling Windows after motherboard swap.

    Overheating, maybe? Are your fans picking up right before it happens? You might run with a temperature monitor app to watch for rising Temps.

    If that’s the issue, check your cooler. Make sure your thermal paste is applied and has good coverage. If using a pre-applied thermal pad that came on the cooler, make sure you pulled off the plastic cover (a common mistake). Make sure you didn’t leave your cooler fans disconnected by mistake. You didnt mention changing anything else in the case, but just make sure your case fans are facing the right way and that nothing is restricting airflow inside and outside the case. If you had bad airflow before but your cpu didn’t run as hot, could be that you got away with it before and just aren’t anymore.

      Did that, it’s in the post. 85C max out of every core under full load. That’s without fans ramping up.

      Stock temp is also normal, 40-45C.

      Plastic cover’s off, thermal paste is sufficient. Fans are properly connected, they are facing the right way (at least I hope they are, w/e, will be finding that out soon anyway)

      I did swap the fan with the CPU. Current one is Thermaright PA 120.

      I am a bit concerned about VRM temps, however. It could be that they give in under extended load. I wonder if undervolting puts an additional strain on those, but why would it if all I do is lessen CPU voltage? (Am new to undervolting, BSOD happens even at stock settings, though)
