QNAP TS-473 and TS-673 memory upgrade

This 32GB kit contains two 16GB DDR4 2400 SO-DIMM modules designed for QNAP TS-473 and TS-673 series NAS servers. The unbuffered, non-ECC memory runs at 1.2V with CL17 timing and uses a 260-pin form factor. It is a direct replacement for the factory-installed memory in compatible units.

Check your NAS model and slot count

Verify that your device is a TS-473, TS-473-4G, TS-473-8G, TS-673, TS-673-4G or TS-673-8G before ordering. The system supports up to 64GB across four slots, so confirm how many slots are free. Mixing with existing modules will force all memory to run at the slowest installed speed.

Ideal for expanding TS-473 or TS-673 capacity

This kit suits owners of the listed QNAP models who need more memory for virtualization or heavy multitasking. It is not suitable for systems that require ECC or registered modules, nor for platforms that use a different pin count or voltage. Buyers needing 64GB total should populate all four slots with matched pairs.

Questions about this item

What is included in the package and do I need to buy anything else to install this kit?

The package contains two 16 GB DDR4 2400 SODIMM modules. No extra parts are required; they plug directly into the 260-pin slots of the listed QNAP NAS models.

Should I choose the 32 GB kit or a larger capacity for my TS-473 or TS-673?

The kit provides 32 GB total. The supported NAS platforms accept up to 64 GB across four sockets, so you can add a second identical kit later if you need the maximum.

What does the 2400 MHz rating mean once the memory is installed in my QNAP NAS?

The modules run at DDR4 2400 (PC4 19200) with CL17 timing at 1.2 V. If mixed with slower memory, the system will operate at the lower speed.
