16GB DDR4 2666 UDIMM for desktop upgrades

This NEMIX RAM module delivers 16GB of DDR4 memory at 2666MHz with CL19 latency. It uses a standard 288-pin UDIMM form factor and runs at 1.2V. The kit is a single 16GB stick built with major OEM chips from Samsung, Micron, or Hynix. It targets desktop users adding capacity to a compatible motherboard.

CL19 latency at 2666MHz speed

The module operates at DDR4 2666 (PC4-21300) with a CAS latency of CL19. This timing figure determines how quickly the memory responds to read requests. It is a non-ECC, unbuffered design without a heat spreader or LED lighting. The 2Rx8 organisation is set by the manufacturer and cannot be changed.

Fits standard DDR4 desktop slots

Installation requires a motherboard with 288-pin DDR4 DIMM slots that accept non-ECC unbuffered UDIMMs. The single-stick layout leaves additional slots free for future expansion if the board has more than one. No extra power cables or cooling are needed beyond the slot itself.

Questions about this item

How fast will my desktop run with DDR4 2666 CL19 memory installed?

The module operates at 2666 MT/s with a CAS latency of 19, so data transfers peak at the PC4-21300 rate once the motherboard enables the XMP or JEDEC profile.

What does the 288-pin UDIMM interface limit in my system?

The 288-pin DDR4 UDIMM slot caps memory speed to the board's maximum supported DDR4 frequency and prevents use of ECC or registered modules.

Will this stick fit in a standard desktop DIMM slot without a heat spreader?

Yes, the bare 288-pin PCB measures the standard UDIMM height and requires only a regular unbuffered DDR4 slot; no extra clearance is needed.
