The Dominator Series Twin2X2048-9136C5D is a 2GB matched pair of DDR2 SDRAM DIMMs built using Corsair's latest high performance heat sink with Dual-Path Heat Xchange (DHX) technology. This part is designed to unleash performance of the new NVIDIA nForce 680i SLI-based platform. This memory has been verified to operate at 1142MHz at latencies of 5-5-5-15. The Twin2X2048-9136C5D comes with Enhanced Performance Profiles (EPP), the open standard for performance module SPD's jointly developed by Corsair and NVIDIA. EPP SPD,s on Corsair modules allow users to automatically configure EPP enabled motherboards with aggressive memory performance settings, for maximum memory and system performance. Performance of these modules incorporating DHX can be further enhanced by using the optional Dominator Airflow Fan, for even more cooling and protection.
