P4C800-3 mobo, P4 3.0 malay, under Mach II r404a bowman modded prommy.
Virgin to ASUS bios...and having trouble getting above 250 fsb using either 1:1 or 5:4 straps for mem settings. I've tried turning off Hyperthreading, PAT, Spread Spectrum etc.
I know I'm missing something simple, I want to be running at or above 4 gigs with this chip and should easily be able to. HELP!!!
