The Dominator Series Twin2X2048-10000C5DF 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 coupled with a Corsair Dominator Airflow Fan. This part is designed to unleash performance of the new NVIDIA nForce 680i SLI-based platform. This memory has been verified to operate at 1250MHz at latencies of 5-5-5-18. The Twin2X2048-10000C5DF 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.
