I have an asus crosshair extreme x670e. It runs rock solid with the 7950x as loneag as my memory is at 4800 mhz. I had some gskill expo but every time I try to run it at 6000, it will run for a bit, then start stuttering and crash. I found out my memory is not on the QVL for my board, so I found some that was (Kingston Fury Beast 6000) and tried that. Runs great at 4800, but again problems at 6000.
I tried a memory stress test on Aida64. At 4800 no problems. At 6000 it gives a hardware failure.
I'm running on bios 0705
