Well, I've only ever owned G.Skill RAM, because this I've only made one build, and it's serving me well. Currently running it at ~ 1333MHz at 7-7-7-20-1T. Could probably run it at 2000MHz 9-9-9-27-2T, but do not feel a need to right now. Reason I got this? It was cheap, and the lifetime warranty is nice. The Ripjaws heatspreaders seem to do their job well, and look great while doing it.
