16GB DDR4 module for Supermicro systems

This 16GB DDR4 2933 UDIMM is built for Supermicro desktop and workstation platforms such as the SuperWorkstation 5039AD-I and motherboards like the MBD-C9X299-PGF. It arrives new as a single 1Rx8 rank stick running at 1.2V with CL21 timing. The unbuffered non-ECC design matches the memory slots on these qualified boards.

Sustained workload behaviour

Modules are stress tested under load to verify stability during extended compute sessions. The major-brand DRAM from Samsung Micron or Hynix maintains the rated 2933 MT/s data rate without throttling. Unbuffered operation keeps latency predictable for multi-threaded applications running continuously.

Build and connector details

The 288-pin UDIMM form factor fits standard DDR4 DIMM slots on the target Supermicro chassis such as the CSE-GS5A-754. No heat spreader is present so clearance inside dense enclosures remains unimpeded. Installation follows the motherboard manual and requires no additional configuration in the BIOS.

Questions about this item

How much power does the 16GB DDR4 2933 module draw when the system runs all day?

The module operates at 1.2V, the standard DDR4 voltage, so power draw stays low during continuous workloads.

What motherboard slot must I already have for this 288-pin UDIMM to work?

A DDR4 UDIMM slot — 288 pins, unbuffered, non-ECC — is required for installation.

Will this CL21 stick run stably alongside older DDR4 modules I keep in the other slots?

Yes, it is a standard DDR4 2933 CL21 1Rx8 UDIMM; the motherboard will negotiate a common speed and latency for all installed modules.
