DESCRIPTION:
This document describes Kingston's ultra low-latency 64M x 64-bit (512MB) DDR2-800 CL3
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 3-3-3-10
at 2.3-2.35V. The SPD is programmed to JEDEC standard latency 800Mhz 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:
