Kingston HyperX 2GB DDR3-1600 Dual Channel Memory Kit Review
 

Despite the Kingston HyperX 2GB DDR3-1600 dual channel memory kit having fairly loose timings (9-9-9-37), it manages to keep pace with other kits rated much more aggressively (7-7-7-18). The performance at 1600MHz and higher was just fine, the only issue I had was that getting there was not as easy as with other kits. Of the five kits used in this review, the one from Kingston was the only one to lack an XMP profile in SPD.
