Using the XMP profile with the newest GB bios worked ok at 8000mhz, but it is unstable. I obviously don't need it to run at 8000, and would rather just have it stable without learning mem overclocking and spending hours tweaking it for max performance. Is there a relatively straight-forward method to getting this to work on a new z790 board and 13900k? I really don't care if it runs at 7000 or anything close - gaming at 4k this is not really going to make a big difference.
