DESCRIPTION:
This document describes Kingston's low-latency 64M x 64-bit (512MB) DDR2-800 CL4 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 4-4-4-12 at 2.0V. 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:
