HPE Server 16GB DDR5 4800 ECC RDIMM

This 16GB DDR5 4800 CL40 registered DIMM is built for HPE servers and workstations that require ECC memory. The 1Rx8 module operates at 1.10V and fits standard 288-pin DDR5 slots. It carries the HPE P50309-B21 part number for direct compatibility.

Who this suits and who it does not

IT teams expanding HPE systems with validated ECC registered memory will find this module a direct match. Buyers needing unbuffered UDIMMs, non-ECC modules, or different capacities should look at other parts.

Deciding specification — DDR5 4800 CL40 1Rx8 ECC

The registered ECC design with CL40 latency at 4800 MT/s determines whether this DIMM works in your HPE platform. Verify the server manual requires registered ECC RDIMMs before ordering.

Questions about this item

What does the 4800 MHz speed mean once the module is installed in a server?

The module runs at DDR5 4800 (PC5 38400) data rate when the system memory controller is configured for that speed.

How does the registered ECC interface affect usable bandwidth and error handling?

The registered buffer adds one clock cycle of latency while the ECC logic corrects single-bit errors and detects multi-bit errors without halting the system.

Will the 288-pin RDIMM fit in a standard HPE server DIMM slot without a heatsink?

Yes, the 288-pin DDR5 RDIMM form factor matches HPE server slots and the module has no heat spreader, so it fits in standard air-flow channels.
