Corsair Introduces Revolutionary Dual-path Heat Xchange (DHX) Memory Technology

[strawroot]

Dual-path Heat Xchange (DHX) is the world’s most advanced memory module thermal dissipation technology. This Patent Pending heat sink technology substantially increases the memory heat sink is used to dissipate the heat generated by the RAMs on the module which has been conducted into the copper ground plane of the PCB.

The second, more typical thermal path is through the back of the BGA packages and into high-performance extruded aluminum heat sinks. Overall, the module has four heat sinks, two connected to the RAMs 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.

The thermal design of the DOMINATOR module is optimized for the use of impinging airflow. Forced air from directly above the module can be used to further enhance the performance of the module. Corsair has developed a DOMINATOR Airflow fan which is designed to be matched with the DOMINATOR heat sinks and allow even more heat to be removed from the DHX XMS2 DOMINATOR modules. This fan unit contains three 40mm tachometer-controlled fans to provide impinging airflow to the memory subsystem. The moderate RPMs required to provide adequate forced air mean the DOMINATOR Airflow fan is nearly silent.

The DOMINATOR heat sink assemblies using DHX technology, with the addition of DOMINATOR Airflow, allows Corsair to guarantee module reliability at over 2.5 volts (2.4 volts, +/- 5%). The combination of this extended voltage and reduced operating temperature allows Corsair to offer modules guaranteed to perform at PC2-8888, or 1,111 MHz, at CAS 4 settings.

As with all other new Corsair XMS modules, the DHX XMS2 DOMINATOR modules are also shipped with Enhanced Performance Profiles (EPP), the new open standard for the Serial Presence Detect (SPD) jointly developed by NVIDIA® and Corsair. EPP simplifies over-clocking for novice enthusiasts and provides unparalleled control for experts.

“The DHX XMS2 DOMINATOR Series is a culmination of all the latest performance module research and design conducted by Corsair” commented John Beekley, VP of Applications at Corsair. “This highly proprietary module design has the most advanced module thermal dissipation technology in the industry, providing unparalleled performance and reliability. The combination of DHX technology with DOMINATOR heat sinks and Airflow unit results in without question the most advanced memory solution available to enthusiasts today.”

“The DHX XMS2 DOMINATOR Series is a natural extension to Corsair’s award winning XMS DDR2 product line”, explained Richard Hashim, Director of Product Marketing. “Over the past few years, we have focused on developing and bringing to market cutting edge module technology. Our ability to manufacture a comprehensive, feature rich range of DDR2 modules that work across both Intel and AMD platforms is what is expected by the enthusiast community. We are really excited about the performance and added reliability our customers are going to see with the DHX XMS2 DOMINATOR Series. Expect to see products in the market as early as next week.”

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 $25.00.

I find those heatsink like heatspreaders immensley ulgy.
