Wow, this ram is just awesome big thumbs up from me. One of the best looking ram out there. Good features with a very nice heat sink to keep it from frying ;D.
Easy to slot into motherboard without any problems.
They are 1600MHz RAM but can fit in any lower then that, it will be just limited to your motherboards max ram(In my case it was limited to 1333MHz) check the motherboards max RAM before you buy this just to make sure it wont slow down the rams performance.
Overall awesome looking ram, easy to install, well done Corsair for making this amazing RAM.
