Test System
Memory kits on test:
G.SKILL ARES 16GB 9-11-10-28 2133MHz
Patriot Division 4 Viper Extreme 16GB 9-11-9-27 1866MHz
Corsair Vengeance 16GB 9-10-9-27 1866MHz
G.SKILL RipjawsZ 16GB 9-10-9-28 1866MHz
Overclocking
Above are the SPD settings of the memory kit in today's review.
Enabling XMP saw the timings and frequency correctly set to 9-11-9-27 at 1.65v.
Overclocking the Kingston DDR3 set was not particularly easy. With the voltage raised to 1.65 to run X.M.P settings, this gave little headroom as we didn't want to fry the kit. Regardless we did push it a notch higher to 1.7v in the hope of reaching 2133MHz. Sadly, with the stock settings maintained at 9-11-9-27 (1T) this resulted in a BSOD and despite various tweaks with the subtimings including slackening off to 2T, we were unable to hit 2133MHz with any stability until the main settings were relaxed to 11-12-11-32 2T. Not the best overclocking results we have had but not a bad performance either. Tightening the timings up we managed 8-9-9-24 but with a drastically reduced bandwidth of 1600MHz. For the purposes of showing the effect of our best overclock on bandwidth we have included those results with the stock settings of the Kingston kit...
