16GB DDR5-4800 ECC Registered RDIMM

This 16GB DDR5-4800 ECC Registered RDIMM is built for Dell servers that require PC5-38400 registered memory. It uses major-brand components and matches Dell part number AC865554 for drop-in compatibility. The module is sold new with a lifetime warranty.

Who this suits and who should look elsewhere

This module suits administrators upgrading or repairing compatible Dell systems that need 1Rx8 registered ECC DDR5 at 4800 MT/s. It is not for desktops or workstations that only accept unbuffered memory. Buyers who need a different capacity, speed, rank configuration or non-Dell platform support should look elsewhere.

Installation and common issues

Installation follows standard RDIMM procedures: power down the server, open the chassis, seat the module firmly in the correct slot and verify detection in BIOS. Common issues include mixing registered and unbuffered DIMMs, populating slots in an unsupported order or using a platform that does not support DDR5-4800 registered memory. Identical modules are supplied for multi-DIMM orders.

Questions about this item

Does this DDR5-4800 ECC RDIMM require a server motherboard with DDR5 slots and registered-memory support?

Yes. The module is DDR5-4800 PC5-38400 1Rx8 ECC Registered, so it only fits DDR5 slots that accept registered DIMMs.

Can I mix this 16GB 1Rx8 registered stick with other registered DIMMs of different capacities in the same server?

Mixing capacities is usually possible if every DIMM is registered ECC and the platform supports the total population, but the exact rules depend on the server model.

How do I confirm the module is running at 4800 MT/s with ECC active after installation?

Check the BIOS memory information or an OS tool such as dmidecode; both will show 4800 MT/s speed and ECC enabled for this part.
