Overclockers Club assigned themselves the daunting task of testing five different sets of DDR3 of varying speed and not only tested them against each other on a Core i7 2600K, ASUS Maximus IV Extreme Memory and HD5870 system but then proceeded to test overclocking.  Take a look at the final standings once the DIMMs cooled off a bit, as well as the specific features that differentiate them beyond their respective top speeds.

"Corsair’s Vengeance series modules are rated for operation at 1600Mhz with latencies of 9-9-9-24 using a low 1.5v. At 1.5v I was unable to get them to scale up to the next memory multiplier which was 1866MHz. However, at the rated speed, the latencies could be tightened up to 7-8-7-27. To reach the next multiplier step I had to increase the voltage to 1.65 with a bump in the TECD from 9 to 10. Once at this step I increased the BCLK of the 2600K to go further with this set, topping out at 1962MHz DDR. That’s a 362MHz or almost 23% bump from the base 1600MHz rated speed. A pretty stout bump in clock speed if you ask me."
