Corsair Memory, a leading producer of high-performing memory modules, has unveiled its new series of memory modules called “Dominator” with modified heat-spreader and ball grid array (BGA) memory chips. The top-of-the-line product in the family works 1111MHz, currently the world’s highest speed-bin for DDR2.

“The DHX XMS2 Dominator series is a culmination of all the latest performance module research and design conducted by Corsair. This highly proprietary module design has the most advanced module thermal dissipation technology in the industry, providing unparalleled performance and reliability,” said John Beekley, vice president of applications at Corsair.

The new XMS2 Dominator modules feature Corsair’s new dual-path heat eXchange (DHX) radiators that cool down memory chips from the back and from the front, like any conventional heat-spreaders, as well as take the heat away from print-circuit board (PCB), which incorporates some additional elements to remove heat from BGA memory chips. In addition to that, Corsair offers to install Dominator airflow fan that provides extra cooling through airflows.

Overall, the module has four heat sinks, two connected to the memory devices and two connected to the PCB. These heat sinks were designed specifically for the personal computing environment, with fins oriented both in latitudinal and longitudinal orientation to take advantage of air provided by CPU fans as well as case fans.  The result is a module with superior thermal characteristics that will run cooler than a module with stamped or mesh heat spreaders, and thus have greater reliability and over-clocking capability.

Currently Corsair offers two flavours of XMS2 Dominator memory modules: PC2-8500 (1066MHz, CL5 5-5-15, 2T) and PC2-8888 (1111MHz, CL4 4-4-12, 2T) without and with additional airflow fan, respectively.

The new DHX XMS2 Dominator series and the Dominator airflow accessory will be available at retailers by the first week of September. Expected retail prices for these modules are from $600-$650 for the TWIN2X2048-8888C4DF and $380-$400 for the TWIN2X2048-8500C5D. The Dominator Airflow is expected to retail for under $25.
