Memory Module Specification
DESCRIPTION:
ValueRAM's KVR667D2D4P5K2/4G is a kit of two 256M x 72-bit 2GB (2048MB) DDR2-667
CL5 SDRAM (Synchronous DRAM) "dual rank" Registered w/Parity memory modules. Total
kit capacity is 4GB (4096MB). The components on each module include thirty-six 128M x 4-bit
DDR2-667 SDRAM in FBGA packages. Each 240-pin DIMM uses gold contact fingers and
requires +1.8V. The electrical and mechanical specifications are as follows:
