I was just looking at my options, speed isn't so important to me when it comes to ram although I might consider some better sticks at some point. They just seem like a good price, they look ok, and they can o/c reasonably well, plus the fact that they're g-skill is alway a plus in my books! So no info on the ram volts then? I'll have to take a peek in the manual - see if it's in there
