I noticed a thing with the warm boot issue on 2 different cpu's. A X2 3800+ and a Opteron 150. As soon as i have the vcore above 1.4, i'll get warmboot issues. At or below 1.4, it's perfectly fine. All kinds of speed and multis where tested to verify this. The problem for me though, is that all my cpu's need just above 1.4 to overclock the max :/. This is with the overvolting option enabled off course. X2's are pretty limited on vcore if i don't use the overvolting option.
