I just bought a new ASUS P4T533 and a PowerLeap PL-iP4. I plan on buying 1GB of pc1066 to use with this board and a new Bios from Mr.Bios so that I may run Hyper Threading cpu's, with the adapter of course. My question is has any one ever tried this type of setup before and worked? Mr.Bios techs tell me that with the new bios, I can run any and all 478pin cpu's.
