Overclocking the Vengeance Pro modules provided some added lift in the performance numbers while maintaining the stock timings of 11-13-13 with only an adjustment needed on the TRAS to 35 along with the prerequisite bump in voltage to 1.75v. Keeping the voltage static at 1.65v would not allow a boot even with looser timings, even up to 13-15-15-35 at 2800MHz, the next divider up from 2666MHz. The maximum clock speed I could pull out of these modules was just over 2900MHz using 1.75v and timings of 12-13-13-35. Any higher than that the performance drop off was not worth the effort for day to day use but would look great in screen shots.
