Detailed Specifications
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.
