That article is almost two years old and probably predates Samsung TCCD chips on Brainpower PCBs. I've said it before and I'll say it again, review sites have always favoured companies such as Corsair and Asus and XFX and other crap because they're the most popular parts in the mainstream consumer market.
I will tell you I have the OCZ Rev2s that were listed in that review (or I think they are anyways), and I have been able to hit 270MHz on them easily and I'm confident they can go even higher. And these are using TCC5 chips which are apparently inferior to the older TCCDs
I've had experience with the chips and I've seen the opinions of people with even more experience than I, and the answers are always the same. Corsair are trash with a flashy name.
