Samsung-made PC2700 memory would also be a good bet, is the Corsair runs too much $$ for your tastes. Every review I have seen, and people who have bought it, can run it very high, probably at least 200MHz DDR w/ 2.7 volts. I believe the Corsair 3000 uses the same chips, just that they hand test every module to 'guarantee' it. So, it is up to you if the guarantee is worth it.
