Registered CL3 ECC 184-Pin DIMM Kit
DESCRIPTION:
ValueRAM's KVR400X72RC3AK2/1GD is a kit of two 64M x 72-bit (512MB) DDR400 CL3
SDRAM (Synchronous DRAM) Registered ECC memory modules. Total kit capacity is 1GB
(1024MB). The components on each module include eighteen 32M x 8-bit (8M x 8-Bit x 4
bank) DDR400 SDRAM in TSOP packages and three 16-bit drivers in TSSOP packages. Each
184-pin DIMM uses gold contact fingers and requires +2.6V. The electrical and mechanical
specifications are as follows:
