To test the G.Skill Eco Series memory modules, they will be put through a series of benchmarks designed to see how well they perform under load. With the set having lower power requirements, I am curious as to how well they will stand up among other sets designed for raw speed. They will be compared to other sets of memory designed for the Intel Socket LGA 1156 platform. The CPU is run at a clock speed of 200 x 16 on the Patriot modules, while the balance of the modules are run with the CPU at 160 x 20 with the memory multiplier of 10 to keep the modules at their rated 1600MHz speed. For the overclocking test, I will use a combination of voltages and timing increases while increasing the base clock on the CPU to increase the clock speed of the modules to see if they are capable of reaching higher speeds to deliver additional performance.

When I put these modules in, I was thinking just how far would they overclock with a paltry 1.35 volts running to them? The short answer is, they do quite well, thank you! The stock timings are 7-8-7-24 with the aforementioned low volts. They easily reached 1804MHz (902MHz Actual) without adjusting the timings or voltages to the modules. I see potential here! Seeing this, I tightened up the CAS latency and TRP to 6 and decided to see where it got me. With 1.35 volts, I didn't go to far, but by increasing the volts on the modules a bit to 1.42v, I was able to reach 1824MHz (912MHz actual). This looked really promising, so I kept moving the volts up and finally had to adjust the TRCD setting to 9, reaching 1946MHz with the timings set to 6-9-6-24 with 1.55 volts, still far from the Intel specified max of 1.65 volts. At this point, I was pretty stoked and figured 1.55 was good so 1.60v should do better. Unfortunately, Memtest stability could not be reached, so I left well enough alone and did not even try to boot into Windows. CAS 6 at almost 2000MHz with 1.5 volts! Not too shabby for a $130 set of modules.
