Compatibility & Use Case

Intended for HPE ProLiant Gen10 class servers and other enterprise platforms that accept DDR4-2666 registered ECC DIMMs. Registered ECC memory is not interchangeable with desktop or unbuffered DDR4 modules, so the host board must list RDIMM support. Typical deployments include virtualization hosts, database servers, and application and file servers where memory error correction is required.
