The Total Micro 862974B21TM is an 8GB DDR4-2400 ECC desktop memory module for compatible systems that require ECC memory and support PC4-19200 speeds.
Recommended For
- Owners of an HPE ProLiant DL20 Gen9 or ML30 Gen9 seeking an 8GB ECC unbuffered DDR4-2400 DIMM replacement or expansion should check their server’s processor and memory configuration; HPE lists the matching 862974-B21 memory option for these systems.
- IT staff maintaining a supported legacy entry server who need to replace a failed 8GB module while retaining ECC error checking and the system’s existing memory configuration.
- Small-server operators adding a single 8GB DIMM to a compatible system with an available slot and a need for ECC unbuffered memory, rather than a higher-capacity memory upgrade.
