This document describes ValueRAM's 512M x 64-bit (4GB) DDR3-1333 CL9 SDRAM (Synchronous DRAM), 2Rx8 memory module, based on sixteen 256M x 8-bit DDR3-1333 FBGA components. The SPD is programmed to JEDEC standard latency DDR3-1333 timing of 9-9-9 at 1.5V. This 240-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows:
The ValueRAM KVR1333D3N9/4G is a 4 GB (512M × 64‑bit) DDR3‑1333 CL9 2Rx8 DIMM designed for high‑performance desktop and server applications. It complies with JEDEC standard 1.5 V operation and features on‑die termination, internal self‑calibration, and bi‑directional differential data strobe.
Key specifications include a 667 MHz memory clock, programmable latency settings, a 0.740 in (18.75 mm) module height, and operating temperature range from 0 °C to 85 °C. The datasheet provides detailed electrical parameters, timing values, and mechanical dimensions for system designers.
