Best RAM for QNAP TS-664



The QNAP TS664 is an impressive piece of kit. The impressive Intel Celeron processor is capable of handling up to 16GB of DDR4 RAM as supported by QNAP. This guide will showcase the best RAM for QNAP TS-664 as well as how to go about installing it.

What RAM is supported by QNAP TS-664

The QNAP TS-664 is either kitted out with an Intel Celeron N5095 or N5105 but both processors are almost identical aside from a few differences in clock speeds. Regardless of which processor you have with the QNAP TS-664, the RAM inside this NAS can be upgraded.

The TS-664 officially supports up to 16GB of DDR4 system memory and QNAP installs 4GB at the factory. Two SODIMM slots are available whereby the single preinstalled module can be removed and two new sticks installed.

4GB is usually enough for most use cases with the best NAS but more will be required for surveillance, virtual machines, and other tasks. Thankfully, QNAP makes it easy to pick modules to upgrade the NAS with both official and unofficial RAM kits available.
