Corsair DDR2-1000: Absolutely The Fastest

By far, the fastest modules we tested came from Corsair. The RAM runs at 500 MHz (DDR1000) and blew us away in latency timing tests with CL3.0 settings. This makes these expensive modules worth their cost. What we don't understand is why the company expects buyers to retain what's printed on the retail package. You can't handle these modules too often, because information printed on their labels isn't smudge-proof. In fact, the printed labels on our modules aren't legible any more. Alas, this makes resale impossible.
