CPU: 5600x
MB : Full ATX B550 Steel Legend
RAM: Ballistix RGB White 4x8GB 3600
BIOS: 1.20

Every time I try to go into the bios to enable XMP, boot fails and I get a post code of d0. Without XMP memory is running at 2667 without issue. I see that the Ballistix RAM is not on the QVL listing. Does this mean I can't use the XMP profile and need to manually add the memory timings into the bios?

After each failed post I pull the CMOS battery, reset and I'm fine. Do I need to update the bios to the most recent version, manually try to input the timings for the memory to achieve the speed I paid for, or just call it a day and tell myself that I'll never miss the minor performance difference?
