FSB = 250 HT Multi = 4x CPU Multi = 11x ram Frequency = 667 Ram voltage = 2.25V @4-4-4-10-15 T1 cpu voltage = 1.49V core 1, 1.45V core 2 Using the OP's formula I'm at 2.74Ghz, I can't seem to get my cpu to 2.8Ghz or higher. I don't know if I should lower the HT or CPU mult. I did cheat one time and just raised the fsb to 274 and left the ram timing on auto, it wasn't stable. It was fast, but I couldn't get it to stay stable. Someone help me reach 2.8Ghz and higher please.
