I don't see how you need 1.45 V at only 4.25 on a 6100. I'm at 4.56 GHz on a 8150 and I only need 1.4375
I think the issue here is FSB...I have mine at 250 and can not run under 1.47v @4.6 stable. Heck...i have not gotten it stable at 1.47 either. It would be nice to post screen shots of our settings so we can see what is goin on.
