Memory Module Specification
KVR266X72RC25L/512D
512MB 64M x 72-Bit DDR266 CL2.5
ECC Registered 184-Pin DIMM
DESCRIPTION:
This document describes ValueRAM's 64M x 72-bit (512MB) DDR266 CL2.5 SDRAM
(Synchronous DRAM) low-profile Registered ECC memory module. The components on
this module include eighteen 32M x 8-bit (8M x 8-bit x 4 Bank) DDR266 SDRAM in TSOP
packages. This 184-pin DIMM uses gold contact fingers and requires +2.5V. The electrical
and mechanical specifications are as follows:
