DESCRIPTION:
This document describes Kingston's 32M x 64-bit (256MB) DDR400 SDRAM (Synchronous DRAM)
CL2 memory module, based on eight 32M x 8-bit DDR TSOP components. This module has been
tested to run at DDR 400MHz at low latency timing of 2-2-2-5 at 2.7V. This 184-pin DIMM uses gold
contact fingers and requires +2.6V. The electrical and mechanical specifications are as follows:
