If you have the power, can you switch this thread over to the Z790 forum?
I thought I had it figured out last night after downloading and reinstalling R23 several times. If I ran it from a shortcut I got the 18K results. If I ran it straight from the installed directory it got way faster.
Power plan is set to Performance and the BIOS was set to Optimized Default to start with; then XMP Tweaked, that is it; I changed nothing else from defaults.
