NEMIX RAM 16GB DDR4 2666 Kit

This 16GB kit contains two 8GB DDR4 UDIMM modules rated at 2666MHz with CL19 latency. It is built for the SuperMicro MBD-C9Z390-CG motherboard and other compatible SuperMicro desktop workstations. The modules are non-ECC and unbuffered for standard desktop use.

DDR4 2666 CL19 1.20V specification

The decisive specification is the DDR4 2666 (PC4-21300) speed combined with 1.20V voltage and CL19 timing. Your system must accept DDR4 UDIMM memory at this exact speed and voltage for the kit to function correctly. Verify the motherboard supports 288-pin unbuffered non-ECC modules before purchase.

Standard voltage low-profile operation

Operating at the standard DDR4 voltage of 1.20V, these modules draw minimal power and run cool without a heat spreader. The bare PCB design keeps the profile low for tight slots while silent passive cooling handles normal workloads. No active cooling or extra airflow is required for typical desktop operation.

Questions about this item

What does the DDR4 2666 speed mean once the modules are installed in a SuperMicro MBD-C9Z390-CG system?

The kit runs at 2666 MT/s with CL19 timing, delivering the standard DDR4 2666 data rate the board’s memory controller expects.

What does the PC4-21300 label on these UDIMMs tell me about the interface limit?

PC4-21300 is the JEDEC designation for DDR4 2666, confirming the modules operate at the 2666 MT/s ceiling of that standard.

Will the 288-pin UDIMM form factor fit the DIMM slots on the MBD-C9Z390-CG motherboard?

Yes, the kit uses the standard 288-pin DDR4 UDIMM layout that matches the desktop DIMM sockets on that board.
