Compatible Supermicro Memory Upgrade

This 16GB DDR4 module is built for the Supermicro MBD-C9Z390-CG motherboard. It targets system builders and IT staff who need a validated memory upgrade for that specific platform.

Unbuffered UDIMM With Standard Pin Layout

The stick uses a 288-pin unbuffered design without a heat spreader, so it fits standard desktop DIMM slots and leaves clearance for large CPU coolers. Major OEM chips from Samsung, Micron or Hynix are used throughout.

Low-Voltage Operation At CL19

Running at 1.2V and DDR4 2666, the module draws minimal power and produces little heat during typical workloads. Passive cooling is sufficient because there is no spreader to trap warmth.

Questions about this item

What DDR4 standard and peak transfer rate does this 2666 MHz module use?

This module runs at DDR4 2666 with a PC4-21300 rating, so the peak transfer rate is 21300 MB/s.

What physical slot and pin count does the UDIMM require?

It is a 288-pin DDR4 UDIMM that fits a standard desktop DIMM slot on the Supermicro MBD-C9Z390-CG motherboard.

How is the single 16 GB stick installed and what step is often missed?

Power off the system, open the case, align the notch on the 288-pin UDIMM with the slot key, press firmly until both retention clips click, then verify in BIOS that the memory is detected at 2666 MHz.
