"Translation Lookaside Buffer (TLB) Error in Original Phenoms
Before Phenom's release, a flaw was discovered in the translation lookaside buffer that could cause a system lock-up in rare circumstances. Phenom processors up to and including stepping "B2" and "BA" are affected by this bug. BIOS and software workarounds disable the TLB, and typically incur a performance penalty of at least 10%. This penalty was not accounted for in pre-release previews of Phenom, hence the performance of early Phenoms delivered to customers is expected to be less than the preview benchmarks. "B3" stepping Phenom processors were released March 27, 2008 without the TLB bug and with "xx50" model numbers." (from wiki)
So what we do it just disable a workarounds and get original Phenom perfomance back. BUT IT COULD CAUSE SYSTEM LOCK-UP IN RARE CIRCUMSTANCES.
But we running a hack dont we?
