Difference between all the Corsair XMS series?

[Cancer12]

I'm surfing Newegg looking to pick up a 512MB stick of Corsair 3200. The problem, however, is that there are tons of different sticks of this stuff with different suffixes. I want to overclock it and run aggressive ram timings. Does anyone know what all the different versiopns are and what the best for overclocking is?
