OWC 16GB DDR4 2666 ECC VLP UDIMM

This module is a 16GB DDR4 2666 (PC4-21300) CL19 2Rx8 VLP ECC unbuffered DIMM. It runs at 1.2V and uses a 288-pin layout without a heat spreader. The part is validated for Supermicro SuperServer 1019C-FHTN8, 1019C-HTN2, 1019S-MC0T, 1019S-WR and 5019C-FL.

Suits Supermicro 1019

Administrators expanding memory in the listed Supermicro SuperServer models will find a direct, JEDEC-standard fit. Buyers who need registered or load-reduced DIMMs, a different voltage, or compatibility with other server platforms should look elsewhere.

16GB module handles typical virtualisation

A single 16GB stick provides headroom for multiple virtual machines or large in-memory datasets on supported systems. Capacity runs out when the application set exceeds the total installed memory across all populated slots.

Questions about this item

Does my Supermicro SuperServer need a free 288-pin DDR4 UDIMM slot to install this 16GB module?

Yes, the module uses the standard 288-pin DDR4 UDIMM form factor, so an available slot of that type is required.

Can I add this CL19 2Rx8 stick alongside existing 2666 MT/s ECC UDIMMs in my 1019C-HTN2?

OWC recommends matching capacity, speed and manufacturer for optimal performance; mixing different ranks or timings may work but is not guaranteed.

How do I confirm the 16GB 2666 MT/s ECC module is recognised after installation?

Check the system BIOS or operating system memory report — it should show the new 16GB DIMM at 2666 MT/s with ECC active.
