Corsair H50 is rocking really well, would love to have their RAM in my rig sigged. (Note: My system won't benefit from the Triple Channel, if I could have a sweet Dual Channel kit that would be nice too)
Corsair RAM has always been on the forefront of superior quality memory. Super stable and overclocks very well. And now they add pizazz to the look of their product which is always a plus!
Corsair kicks ass because they make such a consistently good product. If I want to be sure the memory will work right, I buy Corsair. And usually, they're very competitive on price as well, but that's icing.
Still running my Corsair DDR sticks in my S939 machine... finally upgrading and would love to stick with a reliable memory maker. Those sticks have lasted me 6 years with no issues to date (nearly 100% run time).
