16 GB DDR4 UDIMM for Desktop Upgrades

This NEMIX RAM module provides 16 GB of DDR4 memory in a single 288-pin UDIMM. It runs at 2666 MT/s with a CAS latency of 19 and operates at 1.20 V. The stick is non-ECC and unbuffered, making it suitable for standard desktop motherboards that accept PC4-21300 memory.

Check Motherboard DDR4 Slot and Speed Support

Verify that your motherboard has a free 288-pin DDR4 DIMM slot and supports 2666 MT/s operation at 1.20 V. Confirm the board accepts non-ECC unbuffered UDIMMs and can run at CL19 timings. Consult the motherboard manual for maximum capacity per slot and populated-channel rules before ordering.

Fits Standard Desktop Builds Without a Heat Spreader

The module installs directly into any compatible 288-pin DDR4 slot and requires no additional power connectors. Its low-profile design without a heat spreader clears most CPU coolers and leaves adjacent slots accessible. It frees up capacity headroom for future expansion while delivering the specified 2666 MT/s throughput.

Questions about this item

Will this module work in a motherboard that only supports DDR4 2666 speeds?

Yes, the module runs at DDR4 2666 (PC4-21300) with CL19 latency and 1.20V, matching that speed exactly.

Does the 2Rx8 organization require a specific CPU or chipset to function?

Standard desktop platforms that accept non-ECC unbuffered UDIMMs will recognize the 2Rx8 layout without special CPU support.

Is a heat spreader needed for stable operation at the rated 1.20V?

The module ships without a heat spreader and is validated at 1.20V; typical case airflow is sufficient for standard workloads.
