ok guys, looking for some pointers again. I cant get this board to clock my CPU at all. Ive had this CPU in both a rampage formula and DFI P35 UT T2R and it does 4ghz @ 1.31v in both - 12hrs prime stable. This board wont even boot into windows @ 1.375v. I got the ram linked + synced @ 1600mhz (CPU is 10x400). NB ive had up to 1.6v, SB 1.55v. Ive seriously loosened all memory timings. LOL!

Any ideas?
