It won't affect the overclocking of the CPU as the RAM speeds are untouched.

But get 1.5v for sandbybridge as 1.65v is just out of intels specs for RAM for SB.

I had 1.65v memory and had no overclocking issues with my 2600k. Corsair XMS 3. Hit 5.0GH/z easily.

been running 1.65 ram for a few weeks now no problems here. You should be able to have a stable 5.0ghz with a good air cooler I have a ****ty water loop and can run benches at 5.3 temps never go over 80.

There isn't any difference. However, 1.5v is better if you're overclocking the RAM.

Intel's electrical specs for 2nd Gen Core i3/i5/i7 CPUs list the max RAM voltage as 1.575v, so run 1.65v RAM at your own risk. It might not damage the CPU noticeably or degrade it within a relevant time-frame, but I don't think anyone can know at this point. The risk is yours to take, but it should at least be an informed decision.
