HPE 500660-B21 4GB DDR3 1066 RDIMM Server Memory

HP 500660-B21 – 4GB DDR3‑1066 RDIMM Kit

Overview :

The HP 500660-B21 is a 4 GB DDR3 server memory module intended for engineers and IT infrastructure professionals managing enterprise-class servers. It supplies reliable registered ECC memory with a 1066 MHz (PC3‑8500) data rate and quad‑rank architecture (4Rx8), making it suitable for fault‑tolerant and high‑availability deployments. The module is designed for deployment in server racks, blade enclosures, and dense multi‑node systems—particularly compatible with HPE ProLiant G6 generations and similar platforms. Its registered ECC function and low‑profile design help maintain signal integrity, system stability, and airflow in data‑center environments. The 1.5 V specification and traditional DIMM format ensure it fits standard 240‑pin memory sockets in supported HPE systems, enabling drop‑in upgrades or replacements under maintenance workflows.
