To sum up what we've observed from these tests, Corsair's XMS PC3000C2 is without a doubt some of the most high performing and overclockable memory you're going to find on the market. Not only does it overclock very well but it does so while maintaining aggressive memory settings, which is just as important to overall memory bandwidth and performance as a high FSB. Crucial's PC2700 performed well overall, edging out the XMS PC2700. However, you really can't utilize its full overclocking potential unless you decide to use conservative timings. If high quality RAM is all you need, either one of these sticks will definitely fit the bill. If killer overclocking is what you crave, then Corsair is definitely the way to go.
