Summary: Average Performance Gain

Scaling Summary: DDR3 Memory On Core 2, Core i7, And Phenom II
Summary: Average Performance Gain

Overall, we saw some nice performance improvements on all three platforms, but, as expected, some configurations benefitted more from faster DDR3 memory than others.

Overall, it has to be said that single-digit performance gains are typically not worth the additional investment. Our recommendation still stands: mainstream RAM, which today is DDR3-1066 and DDR3-1333, provides sufficient performance. Spending a bit more money on low latency RAM is typically worthwhile, but faster clock speeds are only justified by better overclocking flexibility. If you have more money to spend, look into a faster processor or a solid state drive, or maybe even a beefy graphics card if you’re into gaming. All of these will yield better performance gains for the dollar than top-frequency RAM.
