Voltage and timings: What's the best value?
Last response: in Memory
I'm curious about the relative importance of voltage and timings, and how each affects real-world overall computing experience.
I'm building a system around an i7 930 processor, and am in the market for a 3x2GB set of DDR3. CAS7 seems to be right within my budget (not willing to pay the premium for CAS6), but there's a lot of variety still: 1.5V vs. 1.5-1.6V vs. 1.65V, frequencies from 1033 to 1600, command rates of 1N vs. 2N, etc. Which factors are most important? Should I always go with the tightest timings or always the lowest voltages, or is it a case of diminishing returns? Does lower voltage allow for more aggressive overclocking or cooler temperatures under load? Is 2N really that much slower than 1N?

The best price/performance RAM IMO is DDR3 1600 CAS 7 RAM with the lowest voltage rating possible. This RAM is excellent, it's DDR3 1600 CAS 7 RAM that runs at 1.5v.

Interesting, I've had that set recommended to me before. Not a bad price point, but are there any potential issues with the 2N command rate? Does this mean it's not possible/recommended to bump up the command rate to 1N?
I also found this set from Mushkin with slightly tighter timings and better price, but with higher voltage and lower frequency. Is it better or worse value per dollar in terms of real world performance?
