We ran our benchmarks using the configurations listed below, always configuring the memories with the lower supported latencies with stability.

CPU Clock	Memory Clock(DDR)
200 x 11 = 2.200 MHz	200 MHz (DDR400)
220 x 10 = 2.200 MHz	220 MHz (DDR440)
245 x 9 = 2.205 MHz	245 MHz (DDR490)
275 x 8 = 2.200 MHz	275 MHz (DDR 550)

If the memory was able to go beyond 275 MHz we controlled the CPU multiplier in order to keep its internal clock as close as possible from its original 2.2 GHz.

During our benchmarking sessions we used the configuration listed below. Between our benchmarking sessions the only variable device were the memory modules being tested.

We adopted a 3% error margin. Thus differences below 3% cannot be considered relevant. In other words, products with a performance difference below 3% should be considered as having similar performance.
