Target QNAP NAS Upgrade

This NEMIX RAM module adds 8GB of DDR4 2666 memory to compatible QNAP systems. It is built for owners who need extra capacity for virtualization, caching or multi-user workloads. The single 1Rx8 SODIMM fits the RAM-8GDR4T0-SO-2666 specification directly.

Straightforward SODIMM Install

Installation takes minutes by opening the chassis and seating the 260-pin stick into the empty slot. No heat spreader is present, so clearance is rarely an issue. The main risk is mixing speeds or ranks; keep all modules at 2666MHz CL19 1Rx8 to avoid boot failures.

Verify Slot And Firmware First

Confirm your QNAP model accepts DDR4 SODIMM memory and has a free 260-pin slot before ordering. Check the current firmware version, as some releases require an update to recognize new capacity. The module runs at 1.2V and is non-ECC unbuffered, matching the factory spec.
