DESCRIPTION:
This document describes Kingston's 64M x 64-bit (512MB) DDR2-800 CL5 SDRAM (Synchronous
DRAM) memory module, based on eight 64M x 8-bit DDR2 FBGA components. This module has
been tested to run at DDR2 800MHz at low latency timing of 5-5-5-15 at 1.95V. The SPD is
programmed to JEDEC standard latency 667Mhz timing of 5-5-5-15 at 1.8V. This 240-pin DIMM
uses gold contact fingers and requires +1.8V. The electrical and mechanical specifications are as
follows:
