Memory upgrades for QNAP NAS systems, listed by model. Every listing on this page is built for one specific QNAP platform — the TS, TVS, TS-h, TDS, ES, HS or QuCPE unit named in the title — with the DDR3, DDR4 or DDR5 module type, speed, ECC type and per-slot capacity that QNAP specifies for that hardware, in single modules and matched kits sized to its slot count. NEMIX does not manufacture memory: it 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.

Find your model

Pick the listing that matches your NAS model exactly (the model is printed on the label and shown in QTS or QuTS hero under Control Panel > System > System Status). Models that share a platform — for example the TS-464, TS-464U and TS-464eU, or the TS-873A and TS-873AeU-RP — take the same module, but each has its own page so the slot count and maximum are correct for that unit.

Single module or kit?

Single-slot units (most TS-x31, TS-x32 and TS-x35 models, and the rackmount TS-x32PXU line) take one module. Two-slot desktop and rackmount units run dual-channel with a matched pair, so choose the 2-module kit when replacing the factory memory or a single module to fill the empty slot. Four-slot TS-h, TVS-h and XU-RP units and the multi-slot RDIMM platforms (ES, TDS-h, TS-h1090FU/1290FX/2490FU, QuCPE-70xx) should be populated in matched sets for full bandwidth; the kit sizes on each page follow QNAP's slot layout.

ECC or non-ECC

Each listing ships the module type QNAP fits at the factory. Several AMD Ryzen and Atom C5125 platforms (TS-x73A, TS-x73AeU, TS-855, TS-1655, TS-h973AX and others) also accept ECC modules; those pages say so, and you can contact us for the ECC version.

Not listed?

QNAP memory is also matched by QNAP part number on the QNAP OEM part number page. If your model is not on either page, contact us with the model number and we will confirm the correct module.
