NEMIX RAM
A 16 GB DDR4 UDIMM running at 2133 MHz with CL15 latency and 1.2 V operation
This 16 GB DDR4 module runs at 2133 MT/s with CL15 latency and 1.2 V operation. It fits standard 288-pin UDIMM slots on compatible desktop motherboards. The single-rank 2Rx8 organisation suits general office workloads and light multitasking. It is sold as a single 16 GB stick for straightforward capacity increases.
The module uses unbuffered non-ECC chips from major OEM suppliers such as Hynix. Absence of a heat spreader keeps the profile low for tight clearances around large CPU coolers. Gold 288-pin contacts ensure reliable seating in the DIMM slot. Day-to-day installation is a simple press-in action without tools or cables.
Swapping an 8 GB or slower DDR4 stick for this 16 GB CL15 module doubles capacity and can improve responsiveness in memory-bound tasks. The upgrade is worth it when the motherboard supports 2133 MT/s DDR4 and the system currently runs with less than 16 GB total. It does not suit platforms that require registered ECC memory or DDR5-only slots.
