Compatible QNAP NAS memory upgrade

This 4GB DDR4 2400 SO-DIMM is built for QNAP TS-473 and TS-673 series NAS units. It arrives as a single unbuffered module rated at 1.2V with CL17 timing. The 260-pin form factor fits the factory memory slots in these servers.

Suitable for capacity expansion only

This module suits owners who need a straightforward capacity increase on supported QNAP models. Buyers who require ECC error correction or registered buffering for data-integrity workloads should look elsewhere. The stick is a 2Rx8 non-ECC design without a heat spreader.

2400 MT/s DDR4 speed rating

The decisive specification is the DDR4 2400 (PC4 19200) speed grade; the system will clock all installed memory to the slowest module present. Verify that your NAS accepts 2400 MT/s DDR4 SO-DIMMs before ordering.

Questions about this item

Does the 4 GB DDR4 2400 SO-DIMM arrive alone or with extra parts?

The package contains one 260-pin SO-DIMM module and nothing else.

Should I pick the 2400 MHz CL17 version or the faster 2666 MHz option?

The module is rated at 2400 MHz with CL17 timing; the 2666 MHz figure appears only in the manufacturer highlights for reference.

What does the 2400 MHz rating mean once the stick is installed in my QNAP TS-473?

The NAS will run the memory at up to 2400 MT/s, delivering PC4-19200 bandwidth at 1.2 V with CL17 latency.
