....backward compatible with 533 Mhz motherboards?
800 FSB CPU can run only @ 533 on 533 mhz mobo's. You can fit them in, but you won't get the performance. =bob=
I understand that ...right now I have the slowest 533Mhz FSB P4 but I'm itching to increase to 3 Ghz and not ready for new mobo just yet. So when I get a new 800FSB mobo in the future I can swap processors without buying a new one. Anyway thanks for the info.
