16 GB DDR5 4800 UDIMM for SuperMicro

This module provides 16 GB of DDR5 4800 memory in a single 288-pin UDIMM. It is built for SuperMicro systems that accept non-ECC unbuffered DIMMs at 1.10 V. The CL40 timing and 1Rx8 organisation match the MEM-DR516L-CL01-UN48 specification.

Suits SuperMicro DDR5 desktops and workstations

It fits owners of compatible SuperMicro platforms who need a straightforward capacity increase without ECC or registered buffering. Builders requiring ECC error correction, registered modules, or speeds above 4800 MT/s should select a different part.

Non-ECC unbuffered DDR5 at 4800 MT/s

The memory operates as non-ECC unbuffered DDR5 at 4800 MT/s with CL40 latency. This single characteristic determines whether the module will function in a given SuperMicro motherboard.

Questions about this item

Will this 288-pin DDR5 UDIMM fit my Supermicro motherboard DIMM slots?

The module uses the standard 288-pin DDR5 UDIMM form factor and is built for Supermicro systems; align the notch with the slot key and press down until the retention clips click.

What is the correct seating procedure for this 1.10 V 1Rx8 stick, and what step do builders often miss?

Open both slot clips, match the module notch to the slot key, press firmly until the clips snap shut automatically; the missed step is failing to verify both clips are fully locked.

Does the lack of a heat spreader on this CL40 4800 MHz module mean I must add active airflow later?

The module ships without a heat spreader; ensure your chassis provides adequate airflow over the DIMM area, as sustained loads rely on case ventilation rather than a dedicated spreader.
