Buy the 1.5v rated kit and don't look back.

Why 1.5v? Doesnt 1.65v offer the best performance?

 

[bryanl]

No memory is rated 1.65v unless it showed failures when tested at 1.50v.

DDR3 Memory is designed for 1.5V. 1.65V puts too much stress on the memory, and it dies fast.

Been there. Done that. I built a whole bunch of comps with "overclocking" 1.65V RAM - 12 months later every single comp had 1 or more sticks go bad.

Swapped to 1.5 V, and not had a single problem since.
