The XMS2 family is Corsair’s mainstream line of performance DDR2 memory. These modules allow users to experience outstanding memory performance and stability. Available in signature black XMS heat spreaders, each module is built using carefully selected RAMs. The Twin2X2048-6400C4 is a 2GByte matched pair of DDR2 SDRAM DIMMs. This part delivers outstanding performance in the latest generation of dual-channel DDR2-based motherboards. It has been tested extensively in multiple DDR2 motherboards to ensure compatibility and performance at its rated speed. This memory has been verified to operate at 800Hz at the low latencies of 4-4-4-12.

The DOMINATOR family of memory represents the ultimate in performance technology engineering from Corsair. The DOMINATOR was designed to have the highest performing IC maximum over-clocking capability and efficient DHX cooling – all the while being stable and reliable. Very few components make it into the DOMINATOR family. Corsair performs rigorous testing and screening on all components to select only the best for the DOMINATOR modules. The tests check for high frequency and/or low latency capabilities for each IC. Then, they are thoroughly tested for maximum interoperability and reliability as a united group to meet the stringent design criteria demanded by performance computing and gaming users. Heat is the enemy of your computer’s key components. And the more you tweak components for performance, the more heat is generated. Heat will slow down your system and impact long term reliability. With traditional DDR2 memory, the standard method of chip packaging involves a BGA (Ball Grid Array). In a BGA, small balls of solder, organized as a grid, are the leads that connect the device to the module circuit board. A Micron Semiconductor study shows that in a BGA memory device as much as 50% of the heat generated by the chip is actually conducted into the circuit board. Since traditional heat sinks are only attached to the front surface of memory chips, there’s no easy thermal path for the heat coming from the back of the chips. Corsair’s engineers have developed a unique technology that maximizes heat dissipation while improving reliability, even in the most extremely overclocked memory module. Dual-Path Heat Exchange (DHX) technology utilizes two methods to effectively remove heat from the memory circuit board - Convection and Conduction.

The Dominator Series Twin2X2048-8500C5D is a 2048 MByte matched pair of DDR2 SDRAM DIMMs built using Corsair’s latest high performance heat sink with Dual-Path Heat Xchange (DHX) technology. This part delivers outstanding performance in the latest generation of dual-channel DDR2-based motherboards. It has been tested extensively in multiple DDR2 motherboards to ensure compatibility and performance at its rated speed. This memory has been verified to operate at 1066MHz at latencies of 5-5-5-15. Performance of these modules incorporating DHX can be further enhanced by using the optional Dominator Airflow Fan, for even more cooling and protection.

Sporting Corsair’s signature fin memory heat sink and patented heat-removing printed circuit board design, the new XMS2 DHX products feature mainstream performance while promoting increased stability. DHX technology allows this memory to have superior thermal characteristics to enable it to run cooler than a module with stamped or mesh heat spreaders. The result is enabled superior reliability, stability and performance capability.. It has been tested extensively in multiple DDR2 motherboards to ensure compatibility and performance at its rated speed.
