Some of you readers probably were thinking why I would use such weird settings for performance tests. I need to say that the G.Skill ECOs are one of the most interesting kits I´ve ever tested. This kit simply doesn´t care about the CL or tRP settings. It´s all about tRCD and that´s how Benchmark Reviews chose the settings. Since I did not knew which ICs were beyond the hood all I had to do was to test every setting possible and compile all my results. This quickly lead to me to discover the key for overclocking this kit was simply raising the tRCD while keeping the rest of the timings as low as possible. Let´s have a look to the chart:
Starting with 6-6-6 timings, we could achieve 1260MHz at 1.35v. Raising vDIMM to 1.5v gave us 1333MHz and finally 1.6v didn´t add that much. The G.Skill ECO kit doesn´t really shine with high frequencies but it does a pretty good job on low latencies. The kit was even able to work at 1333MHz 6-6-5-21 Timings!
After that, we moved to 6-7-6-21 1T and this configuration is really where this kit rocks. Reaching 1333MHz was easy with barely 1.35 volts (while the kit is rated at 7-7-7-21 2T with the same voltage). Raising vDIMM up to 1.5v gave us 1600MHz and finally 1.6v didn´t help that much. Please notice that 1600MHz 6-7-6-21 1T was the best configuration for all our performance results, so, even for motherboards which doesn´t support low-vDIMM voltages this kit should be a nice pair for your processor with low timings and just 1.5 volts.
Finally, rising latencies to 6-8-6 let us start at 1600MHz with barely 1.35 volts! This one could be a nice setup for low-vDIMM motherboards since you´re paying for a 1333MHz kit. This time we could only achieve 1730MHz but that´s almost 400 extra Megahertz from default. While Benchmark Reviews tested 6-9-6 settings they didn´t helped anywhere on frequencies, so we just decided to leave that setup out of the chart.
Please keep in mind that while all memory kits are different, some kits could do better or worse than this, but considering the G.Skill F3 10666CL7D kit was done for mid/high-end P55 motherboards paired with i5-i7 processors, there are big chances on achieving higher frequencies than I got, especially considering my setup was based on a low-end H55+Intel Core i3. Now, before you start asking why I chose this setup, remember I wanted to show you how good could this kit be for HTPCs, where you use very "basic" components and the airflow and heat dissipation is very limited because of the small form factor cases. Also, this way I can show you the advantages of power consumption in a better way rather than utilizing a system that consumes 150 watts or more on idle mode. Let´s head to the Power Consumption paragraph to see the results.
