Corsair TWINX1024-4400 and Kingston HyperX PC4300 Dual Channel Kits
 

As PC performance enthusiasts hit new overclocking heights, enthusiast memory
companies, like Corsair and Kingston, respond by releasing even faster memory to
feed the hunger of the hardcore overclockers. For quite some time, DDR550 or PC4400
was the fastest RAM available. Faster RAM is available now but only from a couple
companies. Very few motherboards can handle these extreme overclocks though, so as
everything gets faster, the selection of usable components gets smaller.
