BSOD after CPU swap (lemmy.world)
submitted 1 year ago* (last edited 1 year ago) by [email protected] to c/[email protected]
 

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.

I would recommend reseating before reinstalling windows. Is your cooling solution also capable for a high tier chip?

[–] [email protected] 1 points 1 year ago

I'll try that when swapping mobos.

Yes, the cooling is enough. I did say 85C was absolute max out of every core. And that's without fans ramping up much.

I had a similar experience before. I tried swapping a i3-2120 to a i5-3300 on a cheap Asrock H67 board. I have installed the latest BIOS and support page said it should work but it just kept blue sreening.

It was fixed after I replaced the MB to a slightly less cheap H77 board.

Friend who helped me fixed the computer said that MB manufacturers don't really test their MBs with all the CPUs they support. Some niche CPUs may not work, even though they are supposedly supported.

Since my lemmy crashes when trying to edit the post, I'll leave an update as a comment.

For now I've limited wattage supplied to CPU, which solved the issue.

So, basically, there are only 3 options which could be the cause.

  1. Wrong automatic motherboard settings. Which seems to be the most likely option.

  2. PSU protection gets wrongly triggered. That would be unusual, this particular model should be reliable.

  3. Faulty CPU. This is even less likely due to the way they're manifactured.
