DESCRIPTION
This document describes Kingston’s 256M x 64-bit 2GB
(2048MB) DDR2-800 CL4 SDRAM (Synchronous DRAM)
memory module, based on sixteen 128M x 8-bit DDR2 FBGA
components per module. This module has been tested to
run at DDR2 800MHz at low latency timing of 4-4-4-12 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:
