Micron 16GB DDR5-4800 ECC UDIMM

This 16 GB DDR5-4800 module delivers error-correcting code protection in an unbuffered UDIMM form factor. It targets administrators who need reliable memory for single-socket servers or workstations that accept unregistered DIMMs. The single-rank 1Rx8 layout keeps electrical loading light on the memory controller.

Check motherboard DDR5 UDIMM support

Verify that the platform accepts DDR5 unbuffered ECC UDIMMs at 4800 MT/s and can operate at the rated 1.10 V. Confirm the board has enough free slots for the desired total capacity and that the BIOS recognizes Micron server DRAM part numbers. No heat spreader is fitted, so ensure case airflow reaches the modules.

Replaces slower or smaller DDR5 ECC UDIMMs

Upgrading from lower-capacity or lower-speed DDR5 ECC unbuffered modules is worthwhile when workloads hit memory capacity limits or bandwidth bottlenecks. The jump makes sense for virtualization hosts, database nodes, or compile farms that benefit from the 4800 MT/s data rate and CL40 timing without moving to registered DIMMs.

Questions about this item

Does the 16GB DDR5-4800 UDIMM come with any cables, brackets or tools, or is it just the memory module?

The box contains only the 16GB DDR5-4800 ECC unbuffered UDIMM module itself; no cables, brackets or tools are included.

Should I pick the 1Rx8 CL40 version or look for a different rank or latency for my server?

This module is a single-rank 1Rx8 design with CL40 timing; choose it when your platform specifies 1Rx8 unbuffered ECC at 4800 MT/s.

What does the 4800 MT/s rating actually deliver once the DIMM is installed in a live server?

At 4800 MT/s with 40-39-39 timings and 1.10 V, the DIMM provides 38400 MB/s peak bandwidth per module.
