Kingston 4GB 512M x 64-Bit DDR3-1600 CL9 240-Pin DIMM is a 2Rx8 memory module based on sixteen 256M x 8-bit FBGA components. This module has been tested to run at DDR3-1600 at a low latency timing of 9-9-9-27 at 1.65V. The SPD is programmed to JEDEC standard latency DDR3-1333 timing of 9-9-9. This 240-pin DIMM uses gold contact fingers.
This document details the Kingston KHX1600C9D3/4G 4 GB DDR3‑1600 CL9 240‑pin DIMM memory module. It describes the module’s architecture, JEDEC‑standard voltage, timing options, and key features such as programmable CAS latency and on‑die calibration.
The manual provides full electrical, mechanical, and thermal specifications, as well as module dimensions and recommended operating conditions. It also includes a disclaimer about over‑clocking and a link for further information.
