DESCRIPTION
ValueRAM’s KVR400D2D8R3K2/4G is a kit of two 256M x 72-bit
2GB (2048MB) DDR2-400 CL3 SDRAM (Synchronous DRAM)
“dual rank” registered ECC memory modules.Total kit capacity is
4GB (4096MB). The components on each module include
eighteen 128M x 8-bit (16M x 8-bit x 8 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:
