hmm, maybe. but wouldn't we hear more widespread issues with using 1.65v? Asus/Corsair say "we've experienced no problems with up to 1.65v". and I would imagine cas7 2133MHz would push the IMC much harder. although thats with 4GB, I'm running 8GB, so but maybe you're right. I'll stick to 2T for now.
though on my most recent chip, I ran 1600MHz/1.65v/2T just to find max clock and still saw degredation. so, I dunno.
thanks for your input though, it's something to think about at least.
