16 GB DDR4 module for Supermicro workstations

This single-rank UDIMM adds 16 GB of DDR4 memory to compatible Supermicro desktop and SuperWorkstation boards. It targets IT professionals and enthusiasts who need a straightforward capacity increase for mission-critical workloads. The module is validated for the MBD-C9Z490-PG and MBD-C9Z490-PGW platforms.

Capacity and headroom at 2933 MT/s

The 16 GB stick runs at DDR4 2933 (PC4-23400) with CL21 latency, providing ample headroom for virtualisation, database caching and multi-threaded applications. Systems requiring more than 16 GB per slot or ECC error correction will need a different module configuration.

Thermals, noise and power draw

Operating at 1.2 V without a heat spreader, the unbuffered module adds minimal thermal load to the memory subsystem. Passive cooling from chassis airflow is sufficient under normal workloads. No active cooling or additional power connectors are required.

Questions about this item

Will this 288-pin DDR4 2933 module run alongside my existing DDR4 sticks in the SuperMicro MBD-C9Z490-PG?

The module is DDR4 2933 CL21 1.2 V; if your current sticks are also DDR4 the system will negotiate a common speed and timing automatically.

How can I verify the 16 GB 1Rx8 module is recognised at 2933 MT/s after installation?

Open Task Manager or BIOS and confirm the slot shows 16 GB, DDR4, 2933 MT/s, CL21 and single-rank operation.

What comes in the box and do I need any extra parts for the SuperMicro board?

The package contains one 16 GB 288-pin UDIMM; no heat spreader, cables or brackets are included or required.
