Hewlett Packard Enterprise DIMM 16GB PC4-2666V-R 2Gx4 (850880-001-MOQ-30)

The Hewlett Packard Enterprise DDR4 Registered ECC 16GB 2400MHz memory module is engineered for server-class environments where reliability and consistent performance are required. This 16GB DDR4 RDIMM supports error-correcting code (ECC) to detect and correct single-bit memory errors, helping to reduce the risk of data corruption in compute and storage servers. With a rated frequency of 2400MHz and registered buffering, the module is intended for use in systems that demand stable multi-channel operation and predictable latency under sustained workloads.

Advantages

This Registered ECC DIMM provides enhanced data integrity through ECC support and registered buffering, which together improve system stability in multi-processor and high-density memory configurations. The 2400MHz speed offers a balance between throughput and compatibility across a wide range of server platforms. The 16GB capacity enables effective memory scaling for virtualization, database caching, and other memory-intensive tasks while maintaining low error rates expected in enterprise deployments.

Suitable for

• Enterprise and cloud servers requiring error correction and high uptime
• Virtualization hosts running multiple VMs or containers
• Database servers and in-memory caching solutions
• Compute clusters and HPC nodes that need stable memory scaling

Key specifications

• Memory type: DDR4 Registered ECC (RDIMM)
• Capacity: 16 GB
• Speed: 2400 MHz
• Form factor: 288-pin DIMM (server DIMM)
• Error protection: ECC (single-bit error detection and correction)
• Buffering: Registered (buffered) for improved signal integrity

How to use

Install the module into a compatible server motherboard DIMM slot following the server vendor's memory population guidelines. Power down the server and disconnect power before installing. Align the notch on the DIMM with the slot key, press firmly until the retention clips engage, and then reconnect power and boot the system. Verify that the server firmware recognizes the installed 16GB module and that memory settings in BIOS/UEFI are configured for ECC and registered operation if applicable.

Recommendations

Use matched memory modules where possible and follow the server manufacturer's supported memory configuration charts to ensure optimal performance and stability. Keep server firmware and BIOS up to date to maintain compatibility with DDR4 Registered ECC modules and enable ECC features in system settings for full error protection.
