128GB DDR5-4800 ECC RDIMM

This 128GB DDR5-4800 ECC Registered DIMM is built for servers that require high-capacity, error-correcting memory. The 4Rx4 organisation and PC5-38400 rating suit dense virtualisation hosts and database nodes. It is supplied as a third-party module with full HPE part-number equivalence.

Verify DDR5 slot count and maximum rank per channel

Before ordering, confirm that your server platform supports DDR5 registered DIMMs and can address 4Rx4 modules at the desired population density. Check the system documentation for the maximum supported capacity per slot and the approved memory-configuration rules for your specific model.

Suits HPE servers needing 128GB registered ECC

This module fits administrators expanding HPE systems that call for the P43334-K21 part number. It is not intended for workstations or desktops that use unbuffered memory, nor for platforms limited to lower-rank DIMMs or earlier DDR generations.
