I have this issue with the motherboard detecting my Athlon XP 3200+ processor, or Corsair XMS DDR 3200LL. It only posts with XMS 2700 and detects processor at 2500+. When I put in one stick of the 3200, it starts to post but hangs at the graphics card bios display (GeForce 6800gt). On the PCChips site, I have the newest BIOS and it supports the 3200+ and DDR 400. What else can it be?
