Basically I got it to run at 3.2 (not primed) and it seemed fine...however I just couldn't hit 3.8 (would go into a reboot cycle).
Eventually I got 3.8 with the following settings:
1.35v CPU
1.255 QPI
1.64 RAM
X36 QPI
x13 uncore
6 RAM divider
190bclk
It seemed fine - again not primed. I went to work yesterday and came home, turned it on and I got the reboot cycle again. Now it won't post with 3.8 as it just goes into a reboot cycle.
I did get 3.8 and it primed fine for 3 hours before I had to turn it off...but next day on a cold boot it just cycled and I had to reset the CMOS
