I can truly vouch to say that Corsair products have been the best I've ever owned or installed for friends. Very reliable but if there is a problem Corsair's RMA department is a pleasure to work with toward resolution.
With the above said, I'm a dedicated Corsair product user and owner. Yeah, I know, I gotta blow some dust out.
Holy Heatsinks, I want to pop those puppies in my X58 and ditch my OCZ crap that can't run it's rating specs. I've RMA's corsair RAM before - painless process and that's just part of why they kick ass. I'll tell you more about how much more ass Corsair kicks after I win me a set of some Vengeance.. (has a nice ring to it)
Corsair has been consitanty on top of performance shootouts and well within their rated specs. Getting some off the shelf perform just like the ones in reviews. Not being a one hit wonder is why Corsair kicks ass.
I love the 6gb kit that I have on my Core i7. Another set would give me a great reason to upgrade upon redeployment. Have not had an issue yet with this set of ram, unlike previous vendors I have used.
Been rocking Corsair memory for some time now, hell I even have a Corsair Heatsink (A50)..... They simply rock. No issues and they even reply back to questions when you email them. The only think sweeter is free... and I like free
