I like using Corsair's products because every one that I've used has always just plain WORKED right 'out of the box". No fuss, no muss, just good quality components working like they are supposed to.
Corsair's been great company to go to for years, never had an issue yet. I've gone through a bit of their high end RAM, and lots of their basic economy RAM sticks for friends n family builds. All of them have always been reliable.
Corsair memory kicks ass because they use high qualilty, stable parts, they pioneer newer, higher speed products before JEDEC certifies it as a new standard, and historically they are stable and lenient overclocker's friends.
I only use Corsair memory in my high test boxes because it's my gold standard in RAM!
