NEMIX RAM
A 16 GB DDR4 SODIMM kit (2 × 8 GB) running at 2666 MHz CL19, built for the POSIFLEX RT-2016-G2 terminal
This NEMIX RAM kit supplies 16 GB of DDR4 2666 memory in two 8 GB SODIMM modules built for the POSIFLEX RT-2016-G2 terminal. The unbuffered non-ECC design matches the platform's standard memory architecture.
Each module runs at 1.2 V with a CAS latency of 19 and a 2Rx8 rank structure. The components use major OEM DRAM from Samsung Micron or Hynix and carry no heat spreader, keeping the profile thin for the terminal's internal slot layout.
The kit replaces the original SODIMM pair in the POSIFLEX RT-2016-G2 when the system needs more capacity than the stock configuration provides. It is not suited for devices that require ECC registered modules or a different pin count.

Power off and unplug the terminal, open the memory compartment, insert each module at an angle until the gold contacts are fully seated, then press down firmly until the side clips click — the step often missed is not pressing hard enough to engage both clips.
No scheduled maintenance is required; the modules have no heat spreader and run at 1.20 V, so only replace them if a memory test reports errors or you upgrade capacity.
The CL19 latency at 2666 MT/s sets the throughput ceiling; under continuous load the memory bus saturates before thermal throttling becomes a factor.
