A quick update here...

I've tried playing a bit and I could get stable at 425 x 8 = 3.4Ghz @ 1.4v

A huge improvement since I kept the clock and even raised the fsb.

vcore = 1.4000v
vmch = 1.75v

Something weird though. My sticks can do 800mhz 4-4-4-12 @ 1.9v. I've ran memtest and orthos when I had a better cooler and ran the CPU @ 400 x 9 daily.

Right now I have to run my memory at 4:3 @ 318mhz

If i try 1:1 which would mean 425mhz it won't get Orthos stable even after i've crancked the vmem up to 2.2v and changed the timmings to 5-5-5-15.

Pretty weird..

Any suggestions?
