## Summary description

Server/PC memory module HP 879507-B21, single 16 GB DIMM designed for internal use in compatible systems. DDR4 architecture with 2666 MHz clock speed and ECC support provides error-correcting capability for improved data integrity. 288-pin form factor and CAS latency 19. Suitable for server and workstation upgrades where ECC DDR4 2666 is required.

## Long description

HP 16 GB DDR4 2666 MHz ECC 288-pin DIMM is a single-module server memory designed for installation in compatible HP and OEM systems that require ECC DDR4 modules. The module provides 16 GB of capacity with a DDR4 interface running at 2666 MHz and CAS latency 19, intended for use in servers and workstations where data integrity and stability under sustained loads are important.
Advantages
This memory module includes ECC support to detect and correct single-bit memory errors, reducing the risk of data corruption in critical applications. The 2666 MHz transfer rate offers a balance between performance and compatibility with many server platforms, while the 288-pin DIMM form factor ensures compatibility with standard DDR4 server memory sockets. CAS latency 19 is specified to match platform timing for stable operation.
Suitable for
 Server memory upgrades requiring ECC DDR4 2666 modules
 Workstations running error-sensitive applications such as databases or virtualization
 Systems where stable long-term operation and data integrity are priorities
Key specifications
 Capacity: 16 GB (single module)
 Memory type: DDR4
 Speed: 2666 MHz
 Error correction: ECC (single-bit error correction)
 Form factor: 288-pin DIMM
 CAS latency: 19
How to use
Power down the system and disconnect it from mains before installing the memory module. Open the server or workstation chassis to access the memory slots, consult the system manual for the correct slot population order and orientation, and align the module with the 288-pin socket. Press firmly and evenly on both ends until the retention clips engage. After installation, reconnect power and boot the system; verify that the new memory is recognized in firmware/BIOS and that ECC is active if supported by the platform.
Usage recommendations
Install memory modules in matched pairs or according to the motherboard manufacturer's guidelines for channel population to achieve optimal performance and ensure ECC functionality. Use compatible modules supported by your server firmware; check system documentation for supported module types and maximum memory capacity.
