Kingston 512MB HyperX DDR2 Memory KHX6400D2LL/512, DDR2-800 (PC2-6400), 240-Pin, Unbuffered

This document describes Kingston's low-latency 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 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.
