Product information

Description

HP 879505-B21 is an internal server and workstation memory module: a single 8 GB DDR4 DIMM rated at 2666 MHz with ECC error-correcting functionality and a 288-pin form factor. The module is intended for system memory expansion and improved stability in compatible servers and professional workstations, providing standard DDR4 performance with CAS latency 19.

Advantages

This 8 GB DDR4 2666 MHz ECC DIMM combines error-correcting capability with industry-standard 288-pin compatibility to maintain data integrity under load. ECC support reduces the risk of single-bit memory errors that can affect server uptime and application reliability. The module’s JEDEC-compliant frequency and timing make it suitable for mixed-population upgrade scenarios where matching DDR4 2666 MHz ECC memory is required.

Suitable for

  • Server memory upgrades where ECC is required for data integrity
  • Workstation systems used for professional applications and data processing
  • Replacing or expanding DDR4 2666 MHz ECC DIMM slots in compatible boards
  • Environments prioritizing stability and error correction over consumer desktop features

Key specifications

  • Memory type: DDR4 DIMM
  • Capacity: 8 GB
  • Frequency: 2666 MHz
  • Error correction: ECC (error-correcting code)
  • Form factor: 288-pin DIMM
  • CAS latency: 19
  • Intended use: server and professional workstation memory

How to use

Power down the system and disconnect it from its power source before installing the memory module. Consult the server or motherboard manual to identify supported DIMM slots and the correct slot population order for ECC modules. Align the 288-pin edge connector with the slot, press firmly and evenly until the module latches into place. After installation, reconnect power and verify that the system BIOS/firmware recognizes the new 8 GB module and that ECC functionality is enabled where applicable.

Usage recommendations

For stable operation, pair this DDR4 2666 MHz ECC DIMM with identical or manufacturer-recommended memory modules. Use modules of the same capacity, speed and ECC capability when populating multiple slots. Keep system firmware up to date and refer to the server or motherboard documentation for supported memory configurations and maximum supported capacity.
