32GB DDR4 kit for QNAP NAS

This 32GB kit contains two 16GB DDR4 2400 CL17 DIMMs built for QNAP TS-677, TVS-682T, TVS-1282T and TVS-1282T3 NAS servers. The modules are unbuffered, non-ECC, 288-pin parts running at 1.2V. They suit administrators who need to expand memory on these specific platforms without changing the existing configuration.

Upgrading from lower-capacity DDR4 modules

The kit replaces smaller DDR4 DIMMs in the four available slots to reach the 64GB maximum supported by these systems. The jump is worth it when workloads such as virtualization or heavy file serving exceed the current memory ceiling. Faster DDR4 modules will clock down to 2400MHz to match the processor capability, so buying higher-speed sticks offers no advantage on these models.

Check your NAS model and slot layout

Verify that your unit is one of the listed QNAP models before ordering. The server provides four DIMM sockets; populate them in matched pairs for best performance. Mixing with existing modules is possible but all memory will run at the speed of the slowest installed stick. No heat spreader is fitted, so ensure adequate airflow inside the chassis.

Questions about this item

Will the 288-pin DDR4 DIMMs fit the four memory slots in my QNAP TS-677?

Yes, each 16 GB stick uses the standard 288-pin DDR4 form factor and the TS-677 provides four DIMM sockets, so both modules install directly.

What is the correct order for seating the two 16 GB modules in the four slots?

Populate the first and third slots (or the pair marked for channel A and channel B) to run the kit in dual-channel mode; filling adjacent slots first is the common mistake.

If I later expand to the 64 GB maximum, do I need to replace these CL17 sticks?

No, you can add two more 16 GB DDR4 2400 modules; all memory will simply run at the slowest installed speed, so the original CL17 kit stays in place.
