Well, things started locking up on me at that speed- so now I'm back to stock speeds.
I'm thinking that I won't be doing any OC'ing at all untill I can get my CPU temps down to reasonable levels (like mid 30's idle instead of low 50s). I'm gonna' go for some AS5 and if necessary- a better cpu cooler. Heck, if I can fit it I'll even go for a ram cooler.
For now, no oc'ing unfortunately.
