They say 'this is a "transformer" in cpu grade" , able to change any clocking you like .
Have better cooling skill it can smoke other brand or model quick !
try google AMD Phenom II TWKR Black Edition (mhz unknow?)

"As I was getting ready to post this information up this morning, I received an e-mail from AMD asking me not to disclose any information detailing the speeds and test results of the TWKR chip. I apologize for this teaser post instead. It seems that AMD does have a plan for this product after all. I will be able to disclose a full report after June 30th. What I can tell you is that the TWKR chip does OC beyond the limits of the 955 BE cpu. Unfortunately, that is also all I can tell you about it. For our test system we’re using the ASUS Crosshair III board and 4GB of Kingston KHX-12800D3K2/4G with a CoolIT Domino A.L.C. cooling unit. I will be giving away one of these special TWKR CPUs to a very lucky winner. Please check back often for instructions on how to enter to win."
