Protect Components While You Push Performance
Pushing performance specs generates heat, and that can compromise reliability and component life. The advanced cooling ability of Dual-path Heat Xchange (DHX) heat sinks keeps your memory safe and reliable even as you push it to the limit. Under the name XMS2 DOMINATOR, this DHX technology will be showing up on both Corsair parts designed for extreme overclocking and on memory designed for performance computing and gaming.
Why Performance DDR2 Memory Must Have Superior Heat Dissipation
Heat is the enemy of your computer's key components. Heat will slow down your system and impact long term reliability. And the more you tweak components for performance, the more heat is generated. 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 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 Unique Dual-path Heat Xchange (DHX) Solves the Problem
Corsair's engineers have developed a unique design that maximizes heat dissipation, even in the most extremely overclocked DDR2 module. The results of recent benchmarks speak for themselves: A DOMINATOR heat sink assembly, using DHX technology and the addition of the Airflow fan, allowed a Corsair module to reach reliable performance at PC8888 or 1111MHz at CAS 4 settings.
DHX Technology uses two paths for the heat to escape from a memory module
1. Conventional dissipation through the front of the BGA chips into a pair of super efficient heat sinks
2. Additional dissipation through the back of the BGA devices and through the circuit board.
Forced airflow further enhances the performance of the moduleOptional DOMINATOR Airflow Fan Boosts Cooling Ability Even More
If you are really planning to push the envelope, choose a DOMINATOR module that includes the optional Airflow fan.
All Modules Feature Enhanced Performance Profiles (EPP)
Corsair and NVIDIA have jointly developed a new open standard that enhanced the Serial Presence Detect (SPD). This exciting new development simplifies the overclocking process while ensuring platform and component compatibility. EPP compatible motherboards can access and take advantage of added performance capability and information. The result: simplified overclocking for beginners and unparalleled control for experts. All XMS2 DOMINATOR modules feature EPP.
