## Summary description

Server/PC memory module HP 815100-B21, 1 x 32 GB DDR4 ECC DIMM with 2666 MHz clock and CAS latency 19. 288-pin form factor designed for internal installation in compatible servers and workstations. Provides error-correcting code (ECC) reliability for critical workloads, virtualization and database applications requiring larger single-module capacity.

## Long description

HP 815100-B21 is a single 32 GB DDR4 ECC DIMM designed for installation in compatible PCs and servers. The module operates at 2666 MHz with CAS latency 19 and uses a 288-pin form factor suitable for standard DDR4 memory slots in workstations and server systems. With error-correcting code (ECC) functionality, this memory module is intended to improve data integrity for critical workloads such as virtualization and database applications that require larger single-module capacity.
Advantages
This 32 GB DDR4 ECC module offers increased single-module capacity to support memory-intensive tasks while providing ECC protection to detect and correct single-bit errors. The 2666 MHz clock speed balances throughput and compatibility across a wide range of server and workstation platforms. Built to the quality standards expected from HP server memory, the module is produced and tested to deliver stable operation under continuous load and to reduce the risk of memory-related downtime.
Suitable for
 Server virtualization hosts
 Database servers and transactional systems
 Workstations running memory-intensive professional applications
 Systems requiring ECC protection for improved data integrity
Key specifications
 Memory type: DDR4 ECC DIMM
 Capacity: 32 GB (single module)
 Clock speed: 2666 MHz
 CAS latency: CL19
 Form factor: 288-pin DIMM
 Error correction: ECC (single-bit error detection and correction)
 Intended use: internal installation in compatible servers and workstations
How to use
Install the module into a compatible 288-pin DDR4 DIMM slot on the server or workstation motherboard following the system manufacturer's instructions. Power down the system and disconnect power before installing to avoid damage. Align the notch on the DIMM with the slot key, press firmly and evenly until the retention clips engage. After installation, power on the system and verify that the BIOS/UEFI and operating system recognize the new memory capacity and ECC functionality. Consult the server or motherboard documentation for supported memory population rules and mixing guidelines.
Usage recommendations
For stable operation, use this HP DDR4 ECC module in systems that explicitly support 2666 MHz DDR4 ECC memory and follow the server vendor's guidelines for memory population and compatibility. When deploying in multi-module configurations, match module capacities and, where possible, use modules from the same vendor and specification family to ensure optimal performance and ECC functionality.
