Corsair DOMINATOR Twin3X2048-1800C7D 2GB DDR3-1800 Memory Kit Review

Corsair DOMINATOR Twin3X2048-1800C7D 2GB DDR3-1800 Memory Kit Review - PCSTATS
Abstract: Corsair's DOMINATOR Twin3X2048-1800C7D kit certainly has impressive specs; two 1GB sticks of DDR3 rated at DDR3-1800 (PC3-14400) speed, and a CAS latency of 7-7-7-20.

Dual Layer Memory Cooling

Each of Corsair DOMINATOR Twin3X2048-1800C7D memory modules is cooled by four individual aluminum heat spreaders that act as one. The system is called the Dual-Path Heat Xchange (DHX) system, and it's basically two large black heatsinks on the DDR3 BGA memory modules, and two smaller silver-cooured aluminum heat spreaders which conduct heat from the PCB itself. The heatspreaders are attached with a strong thermal adhesive, so there is no way to remove any of the heatsinks on this memory without damage.


The Corsair Dominator Fan frame cools up to four memory modules below with a steady stream of quiet airflow.

With the way BGA chips are designed, most of the heat generated in the DRAM actually travels through the solder balls at the bottom and into the PCB. With that in mind, Corsair redesigned the DOMINATOR PCB for board level thermal management and implemented thermal vias - areas where the copper trace lines serve to conduct heat from below the DRAM to the top of the module.

A large gold section along the top of the memory circuit board comes in contact with two the small aluminum heatsinks (one on either side). These heatsinks draw the excess heat away from the PCB itself, for more efficient cooling of the memory modules, and circuit board.


The Corsair Dominator Fan frame cools up the four separate heatspreader components on each memory module.

Corsair's approach does a much better job at keeping DDR3 memory cool than conventional heatspreaders do. To further improve the cooling ability of its memory, Corsair bundles (or sells separately) the DOMINATOR Airflow fan bracket. Equipped with three 40mm fans, this little aluminum device clips onto four memory DIMM slots and blows air directly down onto the DOMINATOR memory heatsinks. During testing the Airflow fan bracket generated little to no noise.
