"Packed full of promise, the latest modules in the Vengeance series of Corsair's DDR4 memory lineup deliver excellent performance when tweaked to get the tightest timings. Out of the box they come with 16-18-18-36 primary timings using just 1.2v to run the modules. By tweaking the applied voltage a little bit you can get the timings much tighter at the rated speed and even when running at my max overclock of 3200MHz. At this speed I was able to run the timings at 15-15-15-28 2T using over 1.4v applied to the modules. The modules were not 100% stable at that speed, but were good for benchmarks all day long, delivering some substantial performance gains when run with a heavily overclocked Core i7 5960X. Full stability was gained at 16-16-16-30, but could be run tighter if you want to drop the module's speed or increase the voltage a bit higher. Although for this test I stuck with 1.45v as my max voltage in the absence of more robust cooling methods.”
