Great set-up...I have the Abit KT7A-Raid with a T-Bird 800@1064, GlobalWin FOP32-1, WW BIOS, everything in BIOS set for max. performance....VERY stable...highly recommend....just get quality PC-133 RAM...I did have issues pushing up the FSB with good PC-100 RAM until I got some of that incredible PC-133 RAM from compuwiz1...that stuff's from another freakin' planet ...soon as I put it in...BOOM, no more issues...I can go up to 1100, but 1064 seems to be a sweet spot...no lock's, nothing....play UT for hours, and never go over 45C.
Just my $0.02
