Chew* this was the highest I could manage 06 stable, and it was done with 1.688Vcore. I could run all the way up to 1.85 vcore but not even the higher vcore could help me get more speed out of all 4 cores. The new pot manage to keep temps between 191C and 185C. NB speed was 3400 to 3500, and higher just would not function....boot. So I will not be able to get any better results wich mean - your result will be safe.
