I've got a 2x1GB kit of this just sitting in it's box as i've decided to get 4GB of cheaper RAM. This RAM is legendary stuff easily capable of 1000mhz at 4-4-4-12 timings. It's no longer for sale as it was only available in small volumes last year when Crucial became 10 years old. Despite it being such a good overclocker, I've
never actually had an opportunity to overclock it due to changing boards and RAM so much.
