Nice BB - you've got a 2.4C right? Mine's a 3.0C - I just hooked up an exos unit and it's getting up to 3.7 easily, but I think the northbridge is overheating. The Asus board is passive and it's getting so hot I can barely touch it. I'm going to put a fan on it and see if that helps. I think I can get 3700 with HT on if I cool the NB down.
Yes, I have a 2.4C, although I'm tempted to try a 2.6C or a 2.8C in the near future. Definitely get better cooling on that northbridge. I've been looking at the northbridge on my IC7, but it seems to be cool. Abit has a pretty nice fan and heatsink on it.
