Intelforums Kingston HyperX 4000 DDR Review has just compiled a thorough review of the Kingston KHX4000K2/1G kit (HyperX 4000): "For those users looking for a very overclockable memory solution, and aren't afraid to do a little tweaking, Kingston's HyperX 4000 memory is a good choice, with our HyperX 4000 reaching 260MHz stable 1:1. For those users unable or unwilling to make the aforementioned adjustments, there may be better memory solutions available. " -- Peter Giencke
