OWC 16GB DDR4 ECC VLP UDIMM

This 16GB DDR4 2666 module is built for the Supermicro MicroBlade 6119G-C2, 6119G-C4 and 6119G-T4. It also fits the Supermicro X11SCM-F and X11SCM-LN8F motherboards. The stick runs at 1.2V with CL19 latency and uses a 2Rx8 unbuffered design.

Who this suits and who it does not

IT teams expanding blade-server memory will appreciate the JEDEC-standard, ROHS-compliant build. Buyers needing registered or load-reduced DIMMs cannot use this unbuffered part. Systems limited to lower capacities or different pin counts should look elsewhere.

Capacity and headroom

A single 16GB rank adds meaningful headroom for virtualisation workloads and multi-application sessions. The 2666 MT/s rate handles typical server duties, though bandwidth-heavy tasks may saturate the bus before capacity runs out.

Questions about this item

Will this module work in my Supermicro MicroBlade 6119G-C2 without any other hardware changes?

Yes, it is a single 16GB DDR4 2666 ECC VLP UDIMM that fits the 288-pin slots of the 6119G-C2, 6119G-C4 and 6119G-T4 and runs at 1.2V.

Can I keep my existing DDR4 2666 ECC UDIMMs and add this OWC stick alongside them?

It will operate at DDR4 2666 CL19 1.2V; for best stability OWC recommends matching capacity, speed, rank (2Rx8) and manufacturer across all populated slots.

How can I verify the module is running at the rated 2666 MT/s with ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode to confirm speed shows 2666 MT/s, voltage 1.2V and ECC type reported as enabled.
