Doing the math so you don't have to; unless you want to

TechSpot is looking to define the relationship between memory and the Core i7 processor with four simple tests. The first and second offer a baseline, with their triple channel kit running default timings at 800, 1066, 1333 and 1600MHz; followed by the same test with all latencies set to the same values. The next two involve tightening the timings and a variety of channel set ups. Read through this rather long article for a serious amount of hard performance data.
"Today we are going to look at how various memory frequencies, timings, and configurations
influence the memory bandwidth and the real-world performance of Core i7 processors. This is
particularly important to not only help you get the most out of your Core i7 CPU, but to
potentially save you a lot of money.
After all, it is possible to configure a Core i7 processor with triple-channel memory operating
at 1066, 1333 and 1600MHz, or even faster. But what are the benefits of using more aggressively
With the new Core i7 platform, DDR3 should finally get its chance to shine. As noted before, the
Core i7 features an on-die memory controller with support for triple-channel DDR3 memory. In
other words, three DDR3-1333 modules operating together will provide a peak bandwidth of 32GB/s
matching the L2 cache performance of a Core 2 Quad Q6600 processor."
