16 GB DDR5-4800 ECC RDIMM

This 16 GB DDR5-4800 module is built for servers and workstations that require registered ECC memory. It runs at 4800 MT/s with CL40 latency at 1.1 V and uses a 288-pin RDIMM form factor. The single-rank 1Rx8 design is compatible with Micron reference parts for stable enterprise workloads.

Suited for registered DDR5 platforms only

This module fits systems that accept DDR5 RDIMMs with ECC and registered buffering. It will not work in platforms limited to UDIMMs, SO-DIMMs or earlier DDR generations. Buyers who need unbuffered memory or a different pin count should look at something else.

1Rx8 single-rank organisation

The 1Rx8 layout defines how the memory controller addresses the chips and affects maximum population rules on many server boards. Verify that your platform supports single-rank registered DIMMs at this density before purchase.

Questions about this item

What speed does the DDR5 4800 PC5-38400 interface run at?

The module operates at DDR5 4800 with a PC5-38400 designation and CL40 latency.

What physical slot and pin count does this 288-pin RDIMM need?

It requires a 288-pin DDR5 RDIMM slot on a server motherboard that supports registered ECC memory.

How is the module installed and what step is often missed?

Align the notch with the slot key, press firmly until the retention clips click, and ensure the motherboard BIOS recognises the registered ECC configuration.
