Speaking of reviews, would you please link me to some low voltage memory overclocking showing poor results. This is the first I have heard of it, but would love some more reading material.

"So to begin with I overclocked the kit. With the intention of pushing the memory frequency up to the first milestone - 1866MHz. It's always a good idea to loosen the CAS timings when overclocking so that nothing affects moving up to the specified frequency. So I slackened the timings to 10-10-10-28. Immediately I ran into problems, so I increased the voltage from 1.25v to 1.6v incase this was hindering the frequency increase. Sadly, although the Sniper kit did boot into Windows and some of the benchmarks did run. It wasn't stable and 3DMark 11 and SANDRA revealed instability. All of our previously tested Sandy Bridge kits managed to move up from 1600MHz to 1866MHz without any problem of stability.

The next objective was to modify the CAS timings at the stock memory frequency of 1600MHz. The idea here is to get the timings as tight as possible and the lowest ratings that I could settle on were 8-9-8-25 @ 1.5v. So I was able to move the kit down to CL8, with a slight modification to the voltage.

With the performance modifications being established I was then able to begin benchmarking. So the Sniper kit will be tested in CL8 and at CL9 (stock) ratings, sadly due to the stumbling block with overclocking we won't be able to test the kit with an uprated frequency setting. The results are on the proceeding pages. To summarise here are the settings we will be testing on the G Skill Sniper's:
Stock: 1600MHz 9-9-9-24 @ 1.25v
Tight: 1600MHz 8-9-8-25 @ 1.5v"

We were able to increase the memory from its stock speed of 1866MHz to 1938MHz. We made sure that the memory was ran as intended using the stock voltage and timings as we generally see a performance decrease by loosening the timings to gain extra speed.

The increased speed from the overclock didn't make a great amount of difference and in certain tests including write and copy we saw a decrease in performance showing that this memory is already at its peak performance.
