DESCRIPTION:
ValueRAM's KVR400D2S4R3K2/1G is a kit of two 64M x 72-bit (512MB) DDR2-400 CL3
SDRAM (Synchronous DRAM) "single rank" registered ECC memory modules. Total kit
capacity is 1GB (1024MB). The components on each module include eighteen 64M x 4-bit (16M
x 4-bit x 4 Bank) DDR2-400 SDRAM in FBGA packages. Each 240-pin DIMM uses gold contact
fingers and requires +1.8V. The electrical and mechanical specifications are as follows:
