Kingston's KHX6400D2T1K2/2G is a kit of two 128M x 64-bit 1GB (1024MB) DDR2-800 CL5 SDRAM (Synchronous DRAM) memory modules, based on sixteen 64M x 8-bit DDR2 FBGA components per module. Total kit capacity is 2GB (2048MB). Each module pair has been tested to run at DDR2 800MHz at low latency timing of 5-5-5-15 at 2.0V. The SPD is programmed to JEDEC standard latency 667Mhz timing of 5-5-5-15 at 1.8V. Each 240-pin DIMM uses gold contact fingers and requires +1.8V.

KHX:DDR2 - It's Here - HyperX DDR2 memory, the next-generation evolution of DDR memory technology. Like all Kingston HyperX products, HyperX DDR2 modules were specifically engineered and designed to meet the rigorous requirements of PC enthusiasts. HyperX DDR2 offers faster speeds, lower latencies, higher data bandwidths and lower power consumption. HyperX is available in single and dual channel memory kits.

Kingston's KHX8500D2K2/2G is a kit of two 128M x 64-bit 1GB (1024MB) DDR2-1066 CL5 SDRAM (Synchronous DRAM) memory modules, based on sixteen 64M x 8-bit DDR2 FBGA components per module. Total kit capacity is 2GB (2048MB). Each module pair has been tested to run at DDR2- 1066MHz at a latency timing of 5-5-5-15 at 2.2V. The SPD is programmed to JEDEC standard latency 800MHz timing of 5-5-5-15 at 1.8V. Each 240-pin DIMM uses gold contact fingers and requires +1.8V
