Unless you plan on overclocking, PC4300 will run 1:1, and will be sufficient. One advantage to some of the high-end RAM(PC6400+) is that you can run it at 533MHZ and very tight timings(3-3-3- 8 or better). But the extra cost of high-end RAM isn't really worth it on a C2D system.I plan on buying a dual core 2 2.4ghz which i think runs at a fsb of 1066.
Am i right in thinking that if i buy PC8500 rated RAM(1066Mhz) then my system will run it at that speed without any overclocking?
