KHX6400D2B1K2/4G
4GB (2GB 256M x 64-Bit x 2 pcs.)
PC2-6400 CL5 240-Pin DIMM Kit
DESCRIPTION:
Kingston's KHX6400D2B1K2/4G is a kit of two 256M x 64-bit 2GB (2048MB) DDR2-800 CL5 SDRAM (Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR2 FBGA components. Total kit capacity is 4GB (4096MB). The SPDs are 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. The electrical and mechanical specifications are as follows:
