NEMIX RAM 32GB DDR4 2666MHz UDIMM

This 32GB DDR4 module runs at 2666MHz with CL19 latency and 1.2V operation. It is built as a 2Rx8 unbuffered non-ECC UDIMM using major OEM chips from Samsung, Micron or Hynix. The kit targets Supermicro desktop and workstation motherboards such as the MBD-C9Z390-CG for memory capacity upgrades.

288-pin unbuffered design without heat spreader

The standard 288-pin DDR4 UDIMM form factor fits directly into compatible desktop DIMM slots without registration or buffering. Absence of a heat spreader keeps the module low-profile for tight clearance around large CPU coolers. Single-module packaging allows flexible population of available slots on supported Supermicro boards.

Verify DDR4 2666 support

Confirm the motherboard accepts DDR4 2666MHz non-ECC unbuffered UDIMMs and supports 32GB density per slot before ordering. Check the system manual for qualified vendor lists and population rules that may limit rank configuration or total memory. Ensure the platform does not require registered or ECC modules for stable operation.

Questions about this item

Does the DDR4 2666 PC4-21300 interface cap real-world throughput at the rated speed?

The module runs at DDR4 2666 MT/s (PC4-21300). Throughput is limited by the motherboard memory controller and the slowest DIMM installed.

What physical slot and clearance does the 288-pin UDIMM need?

It requires a standard 288-pin DDR4 UDIMM slot. No heat spreader is fitted, so low-profile CPU coolers will not interfere.

How is the module installed and which step is often missed?

Align the notch with the slot key, press down until both retention clips click. The step often missed is verifying the clips fully lock on each side.
