A nice feature that Kingston has with the HyperX H2O 2133MHz DDR3 memory kits is dual XMP profiles. The first profile for this kit is 2000Mhz at 9-11-9-27 timings and the second profile is at 2133Mhz also at 9-11-9-27 timings. The reason for the two profile combination is to help those that do not have unlocked processors achieve great performance while maintaining stability. Since my test bench has an unlocked Intel Core i5-2500K 'Sandy Bridge' processor I was able to utilize the faster 133Mhz profile and boot the system with no problem...
