## Long description

HP registered DDR3-1866 16GB (1x16GB) Dual Rank x4 ECC 240-pin DIMM memory module (CAS-13) is a server-grade 16 GB DDR3 module designed for use in compatible HP ProLiant servers and workstations. It operates at DDR3-1866 (PC3-14900) speed and incorporates ECC error correction and registered buffering (RDIMM) to enhance system stability and data integrity in multiprocessor and server environments. The module’s CAS latency of 13 and dual-rank x4 organization provide a balance between performance and reliability for service-critical applications.
Advantages
This HP registered memory module offers ECC support to detect and correct single-bit errors, reducing the risk of data corruption in server workloads. Registered buffering improves signal integrity on multi-module and multi-processor motherboards, contributing to system stability under sustained load. The 240-pin DIMM form factor and standard DDR3-1866 speed ensure compatibility with systems designed for PC3-14900 modules, while the 16 GB capacity helps increase memory density for virtualization, database, and compute tasks.
Suitable for
Upgrading memory in compatible HP ProLiant servers and enterprise workstations
Expanding RAM for virtualization hosts and hyperconverged infrastructure
Replacing faulty server modules to restore system reliability
Applications requiring ECC-protected memory for data integrity
Key specifications

How to use
Install the module into a compatible 240-pin DIMM slot on a supported HP server or workstation following the system manufacturer’s installation procedure. Power down the system and disconnect power before installing to avoid damage. Align the module’s notch with the slot key, press firmly until the module latches into place, then reconnect power and verify memory is recognized in firmware/BIOS. For systems with multiple channels, populate memory according to the motherboard or server documentation to maintain optimal channel balance and performance.
Usage recommendations
Use this RDIMM module in systems that explicitly support DDR3-1866 registered ECC memory. For best results in servers, populate memory channels evenly and pair modules of the same specification and rank. Consult HP ProLiant compatibility lists and system maintenance guides to confirm supported memory configurations before purchase or installation.
