I have an old Neo2 mobo (865pe) that is housing a P4, 2.4ghz processor (533 FSB). I was recently given a 3ghz, P4 that has 800 FSB. I use 2 sticks of pc2700 memory running in dual mode. Since I plan to overclock the new P4 (haha...new P4), can I replace the memory with pc3500 to take advantage of the increased FSB from overclocking? The mobo only supports pc3200 memory. Thanks for all responses to this elementary question.
