1.39vtt for 2000mhz, that might be why I get post code 26 half the time. I figured it wasn't enough vtt as I have read that is one of the reasons to get a post code 26 but I didn't think it required that much. Good to know though. Now I can come back at it with a different angle.

Is this a standard whether it is a C0 or D0 stepping or will each CPU vary?
