I am writing to you guys to see if anyone can help to figure this out. I was checking with AMD overdrive that the Turbo Core engine is set to 3.8 Ghz instead of the 4.1 Ghz that is supposed to provide. I have tried to set the Turbo Core -> Boost Level field to 0 instead of 1, but it is reverted back to 1 always. This must be a BIOS flaw I guess.

Does any of you have a similar problem with your Vishera CPUs?
