NEMIX RAM 16GB DDR4 3200 CL22 1.2V 2Rx8 UDIMM memory upgrade

16 GB DDR4-3200 UDIMM for ASRock B660M boards

This 16 GB DDR4 module runs at 3200 MT/s with CL22 latency at 1.20 V. It uses a 2Rx8 unbuffered non-ECC design on a 288-pin UDIMM form factor. The kit targets owners of ASRock B660M-HDV, B660M-ITX/ac and B660M-ITX/eDP motherboards who want a straightforward capacity increase.

Verify DDR4 slots and maximum supported speed

Your motherboard must accept 288-pin DDR4 UDIMMs and be able to run memory at 3200 MT/s or scale it down automatically. Confirm the board has a free slot and that the BIOS recognises 2Rx8 modules. Systems limited to lower frequencies will still work but will not reach the rated 3200 MT/s.

Fits a standard DDR4 desktop build alongside CPU

The module needs one vacant 288-pin DDR4 slot and draws 1.20 V from the board. No heat spreader is fitted so clearance under large air coolers is generous. Adding this stick leaves remaining slots open for further expansion and does not occupy M.2 or PCIe resources.
