Memory Module Specification
KVR266X72RC25L/2G
2GB 256 x 72-Bit DDR266 Registered
CL2.5 ECC 184-Pin DIMM Module
DESCRIPTION:
This document describes ValueRAM's 256M x 72-bit (2GB) DDR266 CL2.5 SDRAM (Synchronous DRAM) Registered ECC memory module. The components on this module include
eighteen stacked 256M x 4-bit (thirty-six 128M x 4-Bit) DDR266 SDRAM and three 16-bit
drivers in TSSOP packages. This 184-pin DIMM uses gold contact fingers and requires +2.5V.
The electrical and mechanical specifications are as follows:
