Overclocking the G.Skill Ripjaws Z F3-17000CL9Q-16GBZH was very easy, 2400 MHz was reached with some simple primary timing adjustments, and no voltage changes. We were unable to get the next memory multiplier to boot, and BCLK adjustments failed to boot, or failed to net any performance gains once the 125 MHz BLCK divider was enabled. Even so, reaching a full 266 MHz for an overclock under default voltage is nothing to scoff at, and is far more headroom that we expected, considering G.Skill does have several different 2400 MHz kits too.
The G.Skill Ripjaws Z F3-17000CL9Q-16GBZH work really well with the ASUS P9X79 Deluxe board, so if you decide to purchase either this memory, or the ASUS board, you really should consider buying the two together. We cannot stress enough how well each played with each other.
Overclocked Performance Summary
SuperPi showed to be nearly a full second faster using the overclocked settings, and the same CPU speed.
wPrime got a small boost as well, but the gains are not really all that large at all.
AIDA Read Performance got a 500 MB/s boost nearly as much as the difference between the two different JEDEC profiles.
Latency improved by 1.5ns, not a lot, but certain apps will show decent gains from the lowered latency.
WinRAR also got a small boost, but like wPrime, it was very small.
Shogun 2 finally showed decent gains, and allowed the G.Skill Ripjaws Z F3-17000CL9Q-16GBZH to finally beat out the Mushkin kit.
