G.Skill PI 2x2GB DDR3 PC3-12800 Review

Everest Ultimate is the most useful tool for any and all memory tweaking. Everest will reliably measure memory bandwidth of the system as well as latency. With this information, one can discover what is and is not improving bandwidth when tweaking or even just trying various timing and frequency combinations.

The bandwidth numbers are really nice cracking 10K in Everest Read with the overclocked G.Skill PI kit. There isn't really much else to say, at these timings and frequencies, these are the types of bandwidth numbers DDR3 should be putting up.

ScienceMark is an almost ancient benchmark utility at this point in time and hasn't seen an update in a long time. It is, however, still a favorite for accurately calculating bandwidth on even the newest chipsets.

The ScienceMark bandwidth and Everest copy result is a bit interesting with the 4GB kit out-pacing the 2GB kit at the same timings aside from the 2GB kit running at 1T. The larger density must be playing a role there.

The latest in a long line of system benchmarking utilities, PCMark Vantage has quite the heritage and following in the overclocking and benchmarking community. For this memory review, we will simply be utilizing the memory benchmark portion of the software.

The PCMark Vantage memories suite are pretty much what we would have predicted at these clocks but we weren't anticipating to see such gains shown to the 2GB kit over the 4GB at the XMP defaults. Switching between 1T and 2T does lower bandwidth slightly but 200 points in PCMark Vantage is way more than we were expecting.

Again, Everest Ultimate to the rescue in measuring memory latency. Like bandwidth, measuring latency can give us some insight into how the whole memory sub-system is performing.

Like the bandwidth numbers, the latency was also lowered slightly when switching from the 4GB kit at 2T to the 2GB kit at 1T. This is 100% expected and confirmed with these results.
