64GB DDR5 4800 ECC RDIMM Server Memory

This 64GB DDR5 4800 module is a registered ECC DIMM built for server and workstation platforms that require error-correcting memory. It operates at 1.10V with a CAS latency of 40 and uses a 2Rx4 organisation. The part replaces HP part numbers N20162-001, P43333-1A1, P50312-B21 and P56153-001.

Replaces HP DDR5 4800 Registered ECC Modules

The module is a direct equivalent for the listed HP part numbers and upgrades systems currently running lower-capacity or slower DDR5 registered ECC memory. The jump is worthwhile when the platform supports DDR5 4800 speeds and needs the 64GB density per DIMM to reach higher total memory configurations.

Check DDR5 RDIMM Slot Count and Maximum Capacity

Verify that your motherboard or server chassis accepts 288-pin DDR5 RDIMMs and that the memory controller supports 64GB single-rank-equivalent 2Rx4 modules at 4800 MT/s. Confirm the maximum supported memory per slot and the total population limit before ordering.

Questions about this item

Will this 288-pin DDR5 RDIMM fit my server's memory slots?

This module uses the standard 288-pin DDR5 DIMM form factor. It requires a server or workstation motherboard with DDR5 RDIMM slots that support 1.10V operation and registered memory.

What is the correct way to install this 64GB ECC module?

Power down the server and disconnect the power cord. Align the notch on the 288-pin module with the slot key, press firmly until both retention clips click shut. A common error is not fully seating the module so the clips do not engage.

When should I consider replacing this 64GB DDR5 4800 module?

Replace the module if memory diagnostics report uncorrectable ECC errors, if the system fails to POST with the module installed, or if a capacity upgrade is needed beyond the current 64GB configuration.
