DESCRIPTION:
This document describes Kingston's 32M x 64-bit (256MB) DDR2-675 CL4 SDRAM (Synchronous
DRAM) memory module, based on four 32M x 16-bit DDR2 FBGA components. This module has
been tested to run at DDR2 675MHz at low latency timing of 4-4-4-10 at 1.85V. The SPD is
programmed to JEDEC standard latency timing of 4-4-4-12 at 1.8V. This 240-pin DIMM uses gold
contact fingers and requires +1.8V. The electrical and mechanical specifications are as follows:
