I guess thats pretty decent.. now that I added all my Fans I'm doin ok. I actually have a really good Mobo for OC'n stuff.. the eVGA 750i. has some good features.. like a Auto Voltage option. so I just set my FSB to 1333 (Only for my board, don't try same) and set the Voltage to Auto, and the RAM to unlinked, and left the RAM timings at Default.. and without even adjusting my Voltage my board on Auto sets the oc from 2.66 to 3.33GHz all stable and on it's own, I just have it set to always be on that, so when I turn it on. It's already runnin 3.33. actually worked pretty well. I'm thinkin I'll mess around and move it up to 3.6 or 3.8 and see how hot it gets.. otherwise I'm leavin it at it's current OC to 3.33GHz cuz for it to be there, stable, and without me personally adjusting the Voltage.. thats pretty good.
you should be able to get yours to 3.4 pretty decently.. let me kno how it goes...
