QNAP | NAS | OEM COMPATIBLE SKU | CROSS-REFERENCE

Memory upgrades for QNAP NAS systems, matched two ways: by the QNAP memory part number printed on the module or on your invoice (RAM-8GDR4T0-SO-2666, RAM-32GDR4ECT0-UD-3200 and the rest of the RAM-xxx line), and by the NAS model itself. Every listing is a specific DDR3, DDR4 or DDR5 SODIMM, UDIMM or ECC module in the capacity, speed and ECC type QNAP specifies for that platform — not a generic laptop stick. NEMIX RAM researches, matches, and compatibility-tests each module against the QNAP platform it is listed for, and backs it with a lifetime replacement warranty and US-based support.

How to choose

Check the memory type in your NAS spec sheet or in QTS/QuTS under Control Panel > System > Hardware: the form factor (SODIMM vs. long DIMM), ECC or non-ECC, and the maximum per-slot capacity. Most desktop TS and TVS units take non-ECC SODIMM; the ES dual-controller units and many TS-h and rackmount models specify ECC. Match the listing to that spec, then pick the capacity. If your model is not listed or the spec is unclear, contact us with the model number and we will confirm the correct module.
