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.
