Do I need PC2-8000 memory?

[cerebrex]

I'm doing a E6600 watercooled overclocking system w/ a gigabyte DS3... I've been having difficulty choosing memory, and I came across a deal on 2GB Buffalo Firestix PC2-8000 memory for a decent price. I had been eye-balling the PC2-6400 originally.. but I've been wondering if I need this memory for a better overclock - as I just switched from a E4300 to the E6600 recently and haven't adjusted my memory shopping.

Well if you want to overclock your E6600 past 3.6GHz (which is a FSB of 400 x the E6600 multiplier of 9), I'd go for the PC-8000 since it will be able to run at a higher clock frequency as opposed to the PC6400 (1000MHz vs 800MHz). Once you hit an FSB of 400+, you'll start overclocking your PC6400 ram.

If you have PC8000 memory, you should be able to safely reach 500FSB (assuming nothing else in the system stops it from working at those speeds) and 500FSB means 4.5GHz on your E6600.
