Kingston`s KHX6400D2/2G is a 256M x 64-bit 2GB (2048MB) DDR2-800 CL5 SDRAM (Synchronous DRAM) memory module, based on sixteen 128M x 8-bit DDR2 FBGA components. This module has been tested to run at DDR2 800MHz at latency timing of 5-5-5-15 at 1.85V. The SPD is programmed to JEDEC standard latency 667Mhz timing of 5-5-5-15 at 1.8V. This 240-pin DIMM uses gold contact fingers and requires +1.8V. The electrical and mechanical specifications are as follows:
