POSIFLEX TX-5300 memory upgrade

This 16 GB DDR4 2666 SODIMM is built for the POSIFLEX TX-5300 Mini-PC. It targets IT teams and system integrators who need a single-slot capacity increase for point-of-sale or kiosk workloads. The module fits the platform's 260-pin SO-DIMM socket without modification.

Single 16 GB module simplifies installation

The package contains one 2Rx8 stick rated at PC4-21300 CL19 and 1.20 V. No heat spreader is included, keeping the profile low for compact chassis. Non-ECC unbuffered operation matches the TX-5300 memory controller, so the upgrade is recognised immediately at POST.

Verify the TX-5300 has a free SO-DIMM slot

Confirm the Mini-PC currently runs DDR4 2666 memory and that the single 260-pin socket is not already populated. The board must accept non-ECC unbuffered modules; registered or ECC sticks will not work. Check the service manual for the exact disassembly steps before ordering.

Questions about this item

Will the 16GB DDR4 2666 SODIMM need any firmware updates or re-seating over time?

No firmware updates are required. The module is unbuffered non-ECC DDR4 at 1.2V. If the POSIFLEX TX-5300 is moved or vibrated, reseat the 260-pin SODIMM to restore contact.

What limit appears first when the POSIFLEX TX-5300 runs this 16GB CL19 module at full load continuously?

The memory controller caps throughput at the JEDEC 2666 MT/s data rate. Latency stays at CL19. The 2Rx8 organisation and 1.2V supply prevent higher frequency or tighter timing operation.

How much heat and power does the 16GB 1.2V DDR4 SODIMM add when the TX-5300 operates all day?

The module draws 1.2V with no heat spreader. Typical DDR4 SODIMM power at 2666 MT/s is a few watts. Passive airflow inside the TX-5300 chassis is sufficient; no extra cooling is needed.
