RAM Testing Methodology

As with any hardware test, we begin by eliminating as many variables as possible. All benchmarks are conducted using the same system and the same memory modules. Each benchmark begins after a complete system restart and is repeated five times with the averages presented in the results section. To ensure system stability and the reliability of our results, each change to memory speed is fully tested with Memtest86+ and Prime95.

For this review, we are using an Intel Core i7-870 processor. This processor is limited to a memory multiplier of 12. Therefore, to achieve the manufacturer-specified settings, the system bus must be overclocked. Unfortunately, this also affects the CPU frequency. To compensate for this, the CPU multiplier is reduced to bring the CPU frequency as close to the stock frequency as possible.

Below is a table summarizing the hardware settings used in this review. Our benchmarks begin with JEDEC standard frequencies and timings to establish a baseline. Next, we move on to the manufacturer-specified settings, utilizing XMP profiles when possible. Once these benchmarks are completed, we raise the system bus again while keeping the memory timings and voltages at manufacturer-recommended values. After the maximum stable frequency is found, the benchmarks are run one last time.
