DESCRIPTION:

ValueRAM's KVR400D2S4R3K2/4G is a kit of two 256M x 72-bit 2GB (2048MB) DDR2-400

CL3 SDRAM (Synchronous DRAM) "single rank" registered ECC memory modules. Total kit

capacity is 4GB (4096MB). The components on each module include eighteen 256M x 4-bit

(32M x 4-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:

FEATURES:

Note: The module defined in this data sheet is one of several configurations available under this part number. While

all configurations are compatible, the DRAM combination and/or the module height may vary from what is described

here. However, in no configuration will the module height exceed 1.250" (31.75mm).
