Got the board today, tests with 4GB 8000 Reaper X and Q9650.

To start board does not like 9 multi
8 is ok but max fsb =5% over stock base FSB so 1333+5%, 1600+5%, more with duals but not much more with quads.

4GB running memtest clean V2 (brutal) 1000MHZ 1.85V, TRFC 52 was key

early findings on new bios I can't share
