Best price for Corsair DDR3 I've seen! The good stuff not the overpriced 1333Mhz.
The TW3X2G1600C9DHX is a 2048 MByte matched pair of DDR3 SDRAM DIMMs built using Corsair's latest high performance heat sink with Dual-Path Heat Xchange (DHX) technology. This part delivers outstanding performance in the latest generation of dual-channel DDR3-based motherboards. It has been tested extensively in popular DDR3 motherboards to ensure compatibility and performance at its rated speed. This memory has been verified to operate at 1600 MHz at the low latencies of 9-9-9-24.
