6800 CL32 with 2x32 GiB A-die
I had to manually change ODT settings to pry open a window of stability with regard to voltages.

I did get it stable once at 6800 using the older A92 bios but that bios was a nightmare to work with since it was very inconsistent, you could enter the same settings again and suddenly have something very unstable. I also used too loose tRP (34 instead of 32) resulting in poor bandwidth:
