It was the FSB voltage, upped it to 1.25 from 1.20 and got my vcore down to 1.3** so far, I can probably go even lower..
The temp disparity was solved with re-seating my heat sink; now they are all on par with each other and are riding at the lower end of 40's at full load :D
Can't wait to put this thing through a good 24 hours run tomorrow.
