Product information

Description

HP 16 GB DDR4 2666 MHz ECC 288-pin DIMM (1 x 16 GB, CL19) is a server-grade memory module designed for internal system memory expansion in compatible HP and HPE servers and workstations. This 16 GB DDR4 DIMM operates at 2666 MHz with CL19 latency and supports error-correcting code (ECC) to improve data integrity in critical applications, virtualization and database workloads. The 288‑pin form factor fits standard DDR4 DIMM slots used in many rack and tower servers, and the module is engineered to meet qualification and testing standards for reliable operation in enterprise environments.

Advantages

This HP memory module offers ECC support to detect and correct single-bit memory errors, reducing the risk of data corruption in servers and workstations where uptime and accuracy are important. Running at 2666 MHz with CL19 timing, it provides a balance of capacity and bandwidth suitable for multi-core processors and memory-intensive tasks. The 1 × 16 GB configuration gives a straightforward way to increase system memory without replacing existing modules, while the 288-pin DDR4 form factor ensures compatibility with systems that accept standard DDR4 ECC DIMMs.

Suitable for

  • Server and workstation memory upgrades to increase available RAM capacity
  • Virtualization hosts and hypervisor environments requiring reliable ECC memory
  • Database and in-memory applications that benefit from additional DRAM capacity
  • Replacement or expansion in systems that use 288-pin DDR4 ECC DIMMs

Key specifications

  • Memory type: DDR4 ECC DIMM
  • Capacity: 16 GB (single module)
  • Effective clock speed: 2666 MHz
  • CAS latency: CL19
  • Form factor: 288-pin DIMM
  • Error correction: ECC (single-bit error correction)

How to use

Power off the server or workstation and disconnect it from mains power before installing the memory module. Open the system chassis according to the manufacturer’s instructions, locate an empty compatible 288‑pin DDR4 DIMM slot or replace an existing module if needed, and align the notch on the module with the slot key. Firmly press the module into the slot until the retention clips engage. Close the chassis, reconnect power and start the system. Verify that the new module is recognized in BIOS/UEFI or by the system management tools and that ECC functionality is enabled where applicable.

Usage recommendations

Use this HP 16 GB DDR4 2666 MHz ECC DIMM in systems specified to support DDR4 ECC 288‑pin modules and follow server vendor compatibility lists. For best results in multi-module configurations, install modules in matched pairs or per motherboard population guidelines, and use HPE-validated memory combinations when deploying in HPE ProLiant Gen9/Gen10 and compatible platforms to ensure optimal reliability and performance.
