Targeted 16 GB DDR4 module

This 16 GB DDR4 2400 CL17 unbuffered DIMM is built for the listed Supermicro C7, C9 and X11 boards. It installs as a single 288-pin stick running at 1.2 V with 2Rx8 organisation.

Suits single-slot upgrades, not ECC needs

The module fits owners adding one stick to reach the 64 GB four-slot ceiling on these platforms. Builders requiring error-correcting code memory or registered DIMMs should choose a different part.

16 GB per slot, 64 GB total ceiling

Each slot accepts a 16 GB module so a full four-bank population delivers 64 GB. Workloads that exceed that capacity will need a board with more sockets or higher-density modules.

Questions about this item

What motherboard must I already own for this 16 GB DDR4 2400 module to be guaranteed compatible?

The module is validated for Supermicro C7B360-CB-M, C7B360-CB-MW, C7Z370-CG-L, C9Z390-CG-IW, C9Z390-CGW, C9Z390-PGW, X11SCQ and X11SCZ-Q motherboards.

How will this unbuffered non-ECC DIMM behave if I keep older DDR4 sticks in the remaining three slots?

It will run at the lowest common speed and timing across all populated slots; the board supports up to 64 GB total across four sockets.

How can I confirm the stick is operating at DDR4 2400 CL17 after installation?

Check the memory frequency and 17-17-17 timings in BIOS or a tool such as CPU-Z to verify the rated DDR4 2400 CL17 profile is active.
