How We Tested
All memory modules were tested under dual channel configuration (2x 1,024 MB). Since the goal of our review is to measure the memory performance, all benchmarks were conducted with the CPU as close as possible from its original clock speed of 2.2 GHz (Athlon 64 3500+). This insured that the results from our benchmarks were influenced only by the memory clock and by the memory latency.
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.
