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 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 screening.
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.
