This kit is suitable for environments requiring increased memory capacity for demanding workloads such as virtualization, large databases, or high-performance computing.

Compatibility

This memory kit is specifically designed for HPE ProLiant Gen10 Plus and Gen11 servers that support PC5-6400B (DDR5-6400) registered memory.
