The TWINX2048-3200C2PRO is a 2 GByte matched memory pair specifically designed for motherboards using chipsets with dual memory channels. This memory kit consists of two CMX1024-3200C2PRO memory modules that have been tested together on either an 875P or an nForce2 Ultra dual channel DDR motherboard at DDR400 (200 MHz, 2-3-3). TwinX memory kits are designed to provide the ultimate in performance and stability in dual channel boards. As part of Corsair's new XMS ProSeries, each module includes the new high-efficiency aluminum XMS heatsink, and 18 activity LEDs that show the level of memory activity on each bank.
