Thanks guys -- I think I get it, though I'm a bit confused about which is better and why. While looking into it, I had read a post from a guy building his own system where someone recommended he buy a lower voltage RAM, and it was mentioned overclockers prefer lower voltage chips all else equal.
Just for my own curiosity -- do I have this straight?:
- lower voltage chips are considered higher quality RAM and so can be run at a higher voltage than default for an overclocked system (i.e. a 1.35v stick on a 1.5v board is better than a baseline 1.5v chip of otherwise equal specs for this purpose)
- or is it the other way around -- a higher voltage chip is preferable in an overclocked system, because they can boost the voltage on the board to over 1.5v (I don't think that is what you guys said)?
- On the 1.5v board of the mid-2011 iMacs, both will be running at 1.5v anyway; the 1.35v stick may be of higher quality, but it's negligible
- Though they are both the same price, given the 1.5v sticks are in stock, and the 1.35v sticks are not (or maybe they haven't been released yet), you guys wouldn't bother waiting for the 1.35v chips -- won't make any difference in performance, heat build, or stability of the iMac
other random question for someone who's been out of the loop for a bit on this -- is the trend always toward lower voltage chips for the same specs, same as a smaller processor die is? i.e. the lower voltage version is likely a result of a move to a new manuf. fab?
