G.Skill ECO Low-Volt DDR3 Review
Test Setup And Synthetics
To make sure that we get the best performance possible out of the G.Skill DDR3 we ran with our i7 overclocked to 3.5GHz on the excellent MSI P55-GD85 motherboard. As we're testing memory performance rather than absolute system performance, especially on a medium GPU, we're running at 1680x1050 today.
CPU : Core i7 870 @ 3.5GHz
Cooler : Thermalright MX-120 with MX-3 Thermal Paste
Motherboard : MSI P55-GD85
GFX : ASUS GTX275
RAM : G.Skill ECO 1.35v 2 x 2GB @ 1600MHz CL7
RAM : Corsair Dominator 2 x 2GB @ 1600MHz CL8
As this memory is meant to be a low voltage ecologically friendly part we aren't running in an overclocked state for our testing. The speed and timings at 1.35v are sufficient that any overclock would require serious voltage and that is against the ethos of G.Skill ECO. To see how this lower voltage variant performance against a more standard 1.65v kit we're running against the Corsair Dominator.
PC Mark Vantage 64
For our PC Mark test we used the in-built Memory benchmark suite of tests which test the memory in various ways. As you can see despite the ECO nature of the G.Skill it's not short of throughput ability, managing to just edge out the Corsair in all our tests.
The Sandra test is purely about bandwidth and we saw a aggregate of 19.3GB/s. Not shabby at all and again just pipping the Corsair Dominator.
Everest Ultimate Edition
Everest also tests the memory but using a different method to Sandra, and so helps us get a more fulsome view of the capabilities of the G.Skill ECO. We have a nicely linear result with the Write test being the slowest as it always is, Copy in the middle and the Read being the fastest.
The main thing that shocked us was how much faster it is than the Corsair. Of course the CL7 vs CL8 will be a factor, but it's quite a comprehensive beating.
Super Pi XS 1.5
Finally Super Pi mainly is testing the horsepower of the CPU, but naturally as the Pi results need to be stored it does get affected by the write ability of the RAM. Once again the G.Skill ECO is making a mockery of it's "ECO" tag, besting the Corsair.
3D Benchmarks anyone?
