I have not seen the actual documention being released on AMD's site yet for the 133mhz spec'd CPU's. I believe AMD will release a 1Ghz at 133mhz FSB, as well as a 1133mhz/1200mhz/1333mhz TBird Core CPU's. When the Palamino releases it should start at 1.4Ghz and take off where the TBird stops with the 133mhz FSB, but that is all to be seen as of yet. But as far as the CPU's go, I have my 1.2Ghz CPU, which is a "B" model at 100mhz FSB, running at 1333mhz, 10x133mhz FSB with no problems. My Duron 700 and TBird 900 will also run at 133mhz FSB and above with no problem. So don't wait for AMD to release the "C" 133mhz FSB spec'd CPU's, as all will run at that speed I have seen so far.
