Best RAM for the QNAP TS-464
By Devin Chua · Data checked by Owen Nakamura · Updated The QNAP TS-464 ships with 8 GB of DDR4 SO-DIMM, no ECC (2 slots) and officially takes 16 GB. What benefits from the upgrade is specific to this box: the Intel Celeron N5095 (4 cores) hardware-transcodes and runs containers, and those — not plain file storage — are what more memory feeds.

What sets the TS-464 apart
The most interesting QNAP for self-deciders: the PCIe slot makes 10GbE an upgrade, and with QuTS hero the same box runs ZFS instead of ext4. If you choose QuTS hero, the RAID-Z calculator applies, not the RAID calculator. QNAP has no SHR equivalent: mixed drive sizes waste real capacity here.
What more memory buys on the TS-464
The TS-464 takes DDR4 SO-DIMM, no ECC (2 slots) up to an official 16 GB, across 2 slots, starting from 8 GB. Whether that upgrade earns its money is a question about this exact box: the Intel Celeron N5095 (4 cores) transcodes Plex and runs containers, and it is the containers, not the file shares, that ask for more RAM.
The TS-464 uses non-ECC DDR4 SO-DIMM, no ECC (2 slots), so a flipped bit is not corrected. That is rarely a problem in practice, but it is why DIY TrueNAS builders insist on ECC; on the TS-464 you simply match the SO-DIMM spec and standard sticks are fine. 16 GB official. 32 GB runs per forum reports but is not endorsed by QNAP.

Keep calculating
To see how much capacity is left after parity, the TS-464 capacity calculator is preset to its 4 bays and RAID types. For the TS-464, the wider basics of choosing a drive are in the buying guides, where we also explain why CMR rather than SMR is mandatory in any RAID array.
Frequently asked questions
What memory does the TS-464 use?
DDR4 SO-DIMM, no ECC (2 slots), starting from 8 GB. 16 GB official. 32 GB runs per forum reports but is not endorsed by QNAP. It uses standard non-ECC modules.
Can the TS-464's memory be upgraded?
Yes. The TS-464 has 2 slots, officially to 16 GB.
Is more RAM worth it in the TS-464?
Only if you run containers. The TS-464's Intel Celeron N5095 (4 cores) transcodes and runs Docker well, and it is the containers — not file shares — that ask for more than the stock 8 GB.
Can I put third-party drives in the TS-464?
Yes. QNAP locks no drive brand on the TS-464 — its compatibility list is guidance, not a gate — so any CMR NAS drive works.
