Is the stock ram in the 27" iMac 1.35V or 1.5V?
I believe its 1.35
The OEM Apple RAM is 1.5V. The Intel Ivy Bridge i5/i7 CPU memory controllers are designed for 1.5V RAM, but will run stable with 1.35V. If you mix 1.35V and 1.5V RAM, it will run at 1.5V, which will not harm the 1.35V RAM, although it's best not to mix voltages.
I stand corrected ! is there any noticeable difference in performance between the 2 ? the crucial replacement is 1.35
Thanks for the replies!
So indeed the correct replacement ram to buy would be the corsair vengeance which is 1.5v?
