G.Skill PI 2x2GB DDR3 PC3-12800 Review

Benchmarking Methodology:

With the lack of overclocking results our benchmarking is going to be a bit slim this review. We have in the past compared numerous DDR3 speeds to various DDR2 speeds with combinations of timings and all testing has shown higher bandwidth for DDR3 but only marginal gains in programs and games with few exceptions. Just a sample graph outlining where the results will be coming from in the up-coming benchmarks.Instead, we have decided to compare a 2x1GB kit of memory at the exact same timing set as our G.Skill PI 2x2GB kits XMP profile as well as the maximum stable overclock we were capable of at time of the benchmarking at 7-6-6 timings.

As always, the grey bar in the graphs (1) will indicate the rated frequency and timings of the G.Skill Pi 2x2GB kit of memory. These grey results will in fact be the XMP profiles that this system boots with on BIOS defaults. This means the ultra tight secondary timings programmed into this kit will kick in as well as the increases in the FSB. These features should provide very good performance, even at the stock frequency of DDR3-1600.

The middle blue results in the graphs, (2), will portray the performance of a 2x1GB kit of memory at the exact same settings as the XMP profile of the G.Skill PI kit with one exception. The 2x1GB kit will run at 1T instead of the 2T that our 2x2GB kit is running at. This is because all 2x1GB kits at these timings and frequency should be able to run stock at 1T despite many being SPD programmed for 2T operation. Our 2x2GB kit just can't run at 1T which is again, a motherboard chipset limitation we believe.

The last red result in the graphs (3) is reserved for the 'non-stock' settings. At the time of the benchmarking, our highest overall overclock wasn't that high but we have since improved upon that with some headway made on the P5E3-Premium. As predicted before in the overclocking section, the motherboard has been heavily holding us back as it has been a battle every step of the way. We will be showing benchmarking results from the highest semi stable overclock at 7-7-7 we are capable of this kit and memory at this time. The specifications for this setup can be found in the Overclocking Section as the highest dual 32M Super Pi stable at DDR3-1720.

For all of the benchmarks, appropriate lengths are taken to ensure an equal comparison through methodical setup, installation, and testing. The following outlines our testing methodology:

a/ Windows is installed using a full format.
b/ Intel chipset drivers and accessory hardware drivers (audio, network, GPU) are installed followed by a defragment and a reboot.
c/ Programs and games are then installed followed by another defragment.
d/ Windows updates are then completed installing all available updates followed by a defragment.
e/ Benchmarks are each ran three times after a clean reboot for every iteration of the benchmark unless otherwise stated, the results are then averaged.

We have listed the benchmark versions on each graph as results can vary between updates.
