It's great to see how individual memory stacks up against the competition under stock configurations, but we're also going to show how it compares when overclocked. With performance in mind, we're going to compare the maximum overclocked results of the various DDR-2 memory modules PCSTATS has tested in the past which are listed below. Remember, just because memory is clocked fast doesn't mean it's the best thing for a computer. Timings are also important, and getting the right ratio of both is the real key to performance based overclocking!

The Corsair DOMINATOR Twin2X2048-9136C5D is not designed for low latency use (4-4-4-12) which is why it only does moderately well in the low latency testing. High latency, high speed is where the DOMINATOR Twin2X2048-9136C5D shines, and it's pretty darn fast! I think in this case the memory is being limited by the motherboard, it could go faster...

Corsair's Smoking Fast Memory!

Virtually all DDR-2 memory comes with heatspreaders, unfortunately the parts were designed for standards two generations old. In order to effectively cool DDR2 memory at high temperatures the conventional heat spreader design is quickly loosing its usefulness.

Corsair's new DOMINATOR Twin2X2048-9136C5D memory is a prime example of fresh thinking. Not only has Corsair redesigned the heatspreaders, it's also redesigned the circuit board. Much of the heat from the DDR2 BGA DRAM modules actually conducts through the BGA DRAM solder balls to the circuit board below. With that in mind, Corsair uses copper trace lines and thermal vias to move the heat to a heatsink specifically for the PCB. This system allows the memory to run cooler than if it were just using a conventional heatspreader.

The Corsair DOMINATOR Twin2X2048-9136C5D is meant for overclockers, the memory doesn't discriminate, the price tag does that for it. At $530 CDN ($459 US, £234 GBP) only hardcore overclockers with an nVidia nForce 680i based computer system need apply. Simply saying that you get fast memory with the Corsair DOMINATOR Twin2X2048-9136C5D is an understatement, I don't think there's anything faster available at the moment.

At stock speeds the Corsair DOMINATOR Twin2X2048-9136C5D performs very well, on par with the other DDR2 memory that we've tested recently, but overclocking is this memory's specialty.

With tight 4-4-4-12 timings, the Corsair DOMINATOR Twin2X2048-9136C5D was able to reach a respectable 1040 MHz. Loosening up the memory timings allowed the Corsair memory to fly like no other before, hitting a staggering 1240 MHz with just 2.2V! I'm sure that those of you who are patient will be able to squeeze even more out of the memory, it's just dying to be overclocked.
