Okay, so I've been running i7 920 and Corsair Dominator GT 1866 C7 (3x2gb) for over 1.5 years on VTT 1.475v for my 24/7 setup. Anything less, and the ram is not stable. So far no problems. I was under the impression that 1.4v to 1.6v VTT was needed to run high-spec'd memory of its time.

I've been out of the loop, but is it considered 'safe' for 24/7?
