Setup notes
Three high-speed modules, all toting 6GB capacity, and run on an Intel Core i7 965 Extreme Edition with a 143MHz BCLK, enabling the 2GHz kits to hit, well, 2GHz, by using a 14x DRAM multiplier. The HyperX modules completed a three-hour Memtest86+ burn-in test without failure.Comparison Crucial Ballistix Tracer was run with a 10x multiplier, leading to a clock-speed of 1,430MHz, or 170MHz below its rated frequency. The need to run a 143MHz BCLK clock means that this is the closest speed we can achieve without going over 1,600MHz. The next step up, using a 12x multiplier, would lead to DRAM operating at 1,716MHz.
We're looking to see what effect, if any, having slightly higher latencies has on performance. Going by historical results it will be negligible, but let's head to the benchmark section and find out.
