DESCRIPTION:
Kingston's KHX4000K2/1G is a kit of two 64M x 64-bit (512MB) DDR500 CL3 SDRAM (Synchro-
nous DRAM) memory modules. Total kit capacity is 1GB. The components on each module include
sixteen 32M x 8-bit (8M x 8-bit x 4 Bank) DDR500 SDRAM in TSOP packages. Each 184-pin DIMM
uses gold contact fingers and requires +2.6V. The electrical and mechanical specifications are as
follows:
