G.Skill 6GB PC3-12800 Triple Channel DDR3 Kit Review

Memory Benchmarks

Everest Ultimate is the most useful tool for any and all benchmarkers or overclockers. With the ability to pick up most voltage, temperature, and fan sensors on almost every motherboard available, Everest provides the ability to customize the outputs in a number of forms on your desktop. In addition to this, the memory benchmarking utility provides a useful tool of measuring the changes to your memory sub-system.


In the Everest Bandwidth test it should come as no surprise that the CL10 result leads the way, but the slightly disproportionally high CL10 result is due to the fact that the Uncore/Integrated Memory Controller is running at 3733Mhz, which is the minimum selectable speed when running at DDR3-1866, while the other configurations are held back a bit by the stock 3200Mhz Uncore frequency. In the other results, we see quite linear read and copy speeds, and nearly identical write speeds due to the fact that they all share the same Uncore frequency.


We were surprised to see the CL10 achieve such a lower latency than CL7, the massive clock speed difference overcomes the inherently loose timings, and evidently the Core i7 processors respond very well to increased memory frequency.


Although last updated almost 3 years ago, and despite its rudimentary interface, ScienceMark v2.0 remains a favorite for accurately calculating bandwidth on even the newest chipsets.


As in Everest, we see a very linear bandwidth increase across the board, with a slightly disproportional CL10 result due to the aforementioned higher Uncore frequency. These synthetic benchmarks do suggest that the Core i7 processor can achieve some remarkable numbers with highly-clocked triple-channel DDR3 memory kit, but does actually translate into faster real-life performance? That is what we are going to find out next.
