QNAP NAS DDR4 Upgrade Kit

This 32GB kit contains two 16GB DDR4 SO-DIMM modules built for QNAP TVS-473 and TVS-673 series NAS servers. It delivers 2400MHz speed with CL17 latency at 1.2V. The unbuffered, non-ECC design matches the factory specification for these appliances.

Four-Slot 64GB Ceiling

The compatible platforms provide four memory sockets and a maximum capacity of 64GB. Installing this 32GB kit occupies two slots and leaves room for a second matched pair. All installed modules will operate at the speed of the slowest stick or the CPU limit.

Non-ECC Unbuffered Requirement

These systems require 260-pin DDR4 SO-DIMMs that are non-ECC and unbuffered. Buffered, registered or ECC modules will not function in the TVS-473 or TVS-673 platforms. Verify the existing memory type before ordering.

Questions about this item

Should I choose the 32 GB kit or fill all four slots to reach 64 GB?

The kit provides 32 GB (2 x 16 GB); the platform supports up to 64 GB across four sockets, so adding a second identical kit will reach the maximum capacity.

What does the 2400 MHz rating mean once the modules are installed in my QNAP NAS?

The memory will run at 2400 MHz (PC4-19200) with CL17 timings at 1.2 V; if mixed with slower modules the system will clock down to the lowest speed present.

Is the 260-pin SO-DIMM interface the right one for my TVS-473e or TVS-673 series NAS?

Yes — these modules are 260-pin DDR4 SO-DIMMs, the exact form factor used by the listed QNAP TVS-473 and TVS-673 models.
