Yes, the TH7-II can run 533MHz FSB P4's. One thing to note about the TH7-II, you will have a whale of a time trying to run PC1066 on it at high FSB. The modules will default to a 4x RD multiplier and the DRCG's on the board will be your limiting factor in an OC. However, that being said, the TH7-II is still my favorite RD solution, one can achieve really nice high FSB OC's with some good PC800 RDRAM and a 3x RD multiplier and not sacrifice the memory bandwidth if say, youre hitting in the upper 160's. Good board, good choice, I still wish Abit would have put some time into making an updated RD solution. Oh well, Granite Bay it is for the next step in the quest for memory bandwidth.
