Corsair XMS2 Xtreme Performance 4GB PC2-6400 DDR2 DIMM Dual Channel Memory Kit
We're not sure why CORSAIR doesn't make 1066MHZ memory anymore for DDR2 devices, though our guess would be the top memory maker has already moved on to DDR3 for the most part. Regardless, one thing CORSAIR perhaps wins out on compared to any other memory maker in the business is their longstanding reputation as not only a top memory maker, but also one with quality as a top priority. As a result, even if it isn't the fastest DDR2 memory out there, CORSAIR's 4GB 800MHZ DDR2 memory is still a fantastic set of chips for your PC. Depending on your budget and clock speed interests, CORSAIR promises performance for all and offers some of the best 800MHZ DDR2 memory out there.
