When I buy my P4 2.6 (800) I want to OC it ti 3.2ghz. Now someone told me that they have the same setup as me but only run PC3500 RAM at like 1025FSB. When I posted this question on some other forums people are telling me in need PC4000 at 1000FSB. My question is who is right or are they both right. And what are the advantages/disadvantages of both and is it worth it to fork out $150 more for PC4000 RAM.
