This document describes ValueRAM's 256M x 72-bit (2GB) DDR3-1333 CL9 SDRAM (Synchronous DRAM), 1Rx8, ECC memory module, based on nine 256M x 8-bit DDR3-1333 FBGA components. The SPD is programmed to JEDEC standard latency DDR3-1333 timing of 9-9-9. This 240-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows:
This document describes the ValueRAM KVR1333D3S8E9S/2GHC 2 GB DDR3‑1333 CL9 ECC memory module, a 240‑pin DIMM built with nine 256 M × 8‑bit FBGA components. It is intended for server and workstation applications requiring error‑correcting code (ECC) memory.
Key features include JEDEC‑standard 1.5 V operation, programmable CAS latencies of 9‑6, an 8‑bit pre‑fetch architecture, bi‑directional differential data strobe, on‑die termination, and a thermal sensor (Grade B). Mechanical specifications list a PCB height of 1.18 in (30 mm) and a single‑sided component layout.
