Testing Methodology: DDR3 RAM
At Benchmark Reviews we need to test memory without adding any other factors to the results. While testing stock speeds is usually easy, it only gets more difficult when we want to add overclocked results. We need to make some changes to the BIOS values and test each configuration to ensure maximum stability. First, I set the values on the BIOS and run Memtest to check if the kit is stable or not. After that, I test with OCCT Perestroika to check if the CPU is stable along with the whole system.
Finally, Benchmark Reviews decides which frequencies are going to be shown in the graphics in order to leave the CPU factor outside of the equation. This way you´ll probably see small differences between memory frequencies, latencies and voltage reflected on our charts without the CPU interfering in the results. Benchmark Reviews uses the following tests suites and applications:
As you can see, I tested the G.Skill ECO 4GB kit in a HTPC-like PC. Since the ECOs were done to achieve maximum efficiency and lower temperatures I thought it was a good way to test them. The CM Elite 100 doesn´t have any fans or great airflow, so it was a good way to see if this kit can work in small form factor cases and stay stable while doing some overclock. This configuration will reflect bigger results on power consumption since the system won´t consume as much as a high-end PC.
While we used a H55 based motherboard, as long as we enabled the XMP the motherboard worked at 1.35v without any problems. Unluckily, we could not raise voltage from this point, so either we worked at 1.35v or we disabled the XMP to start at 1.5v. Following this path, I had no other choice but testing different frequencies, latencies, and power consumption at 1.35v, 1.5v at finally 1.6v. A deeper explanation about the Overclocked results will appear on the next pages. The G.Skill ECO setup was the next for the benchmark and applications performance tests:
