## Summary description

HP 879505-B21 is an internal server/PC memory module with a single 8 GB DDR4 DIMM operating at 2666 MHz. It features ECC error-correcting functionality, 288‑pin form factor and CAS latency 19. Designed for system memory expansion and stability in servers and workstations, suitable for upgrading or replacing compatible DDR4 2666 MHz ECC slots.

## Long 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.
