Test Methodology and Overclocking

We're testing Corsair's 12GB Vengeance kit using the default XMP settings - that's 1,600MHz with latencies at 9-9-9-24 at 1.5V. The standard command rate is set to 2T.
Providing the comparison is a couple of 6GB kits that represent the opposite ends of the memory market; a cheap-and-cheerful 6GB ValueRAM kit from Kingston, and a high-end Dominator kit from Corsair.
The specification of each comparison kit, as well as a summary of our test system, can be found in the tables below.

Overclocking
If you're eyeing up a Vengeance memory kit, there's a good chance you're toying with the idea of overclocking it.
Sticking to the default 1.5V, we were able to raise the speed of the tri-channel kit to 1,740MHz without having to loosen the timings.

Pushing the memory a little bit further, we then kept latencies at their default 9-9-9-24, but raised voltage to 1.65V. Doing so enabled us to hit 1,870MHz - a boost of 270MHz. There's plenty of overclocking potential available, and users willing to sacrifice latencies will no doubt push the Vengeance modules to the 2,000MHz mark.
