Kingston HyperX KHX9600D2K2/2G DDR2 2GB Memory Kit Review
The Kingston didn't come close to its enormous 1,200MHz rated speed on our Abit P35 test platform but neither did the OCZ we used for comparison. Of course that's disappointing but the KHX9600 was rock-steady and delivered sterling performance at a surprisingly reasonable price.
