VR1066D3N7/2G(2GB 256M x 64-Bit PC3-8500 CL7 240-Pin DIMM)

DESCRIPTION:This document describes ValueRAM's 256M x 64-bit 2GB (2048MB) DDR3-1066 CL7 SDRAM

(Synchronous DRAM) memory module, based on sixteen 128M x 8-bit DDR3-1066 FBGA components.

The SPD is programmed to JEDEC standard latency 1066Mhz timing of 7-7-7 at 1.5V. This 240-

pin DIMM uses gold contact fingers and requires +1.5V.

The electrical and mechanical specifications are as follows:
