This document describes Kingston's 512M x 64-bit (4GB) DDR3-1333 CL7 SDRAM (Synchronous DRAM), 2Rx8 memory module, based on sixteen 256M x 8-bit FBGA components. This module has been tested to run at DDR3-1333 at a low latency timing of 7-7-7-20 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. The JEDEC electrical and mechanical specifications are as follows:
This document provides the detailed specifications for Kingston's KHX1333C7AD3/4G 4 GB DDR3‑1333 CL7 240‑pin DIMM. It describes the module’s electrical and mechanical characteristics, including timing, power consumption, and temperature ranges.
Key features include JEDEC‑standard 1.5 V operation, programmable CAS latency (9‑8‑7‑6), bi‑directional differential data strobe, on‑die termination, and a PCB height of 1.180 in. The sheet also notes that the module uses gold contact fingers and includes a heat spreader option.
