Targeted NAS Upgrade

This 4 GB DDR4 module is built for QNAP TS-1273U, TS-1277 and TS-1673U NAS servers. It plugs directly into the 288-pin DIMM slots and runs at 2400 MHz with CL17 timing. The stick is validated for those models so administrators can expand capacity without compatibility guesswork.

Thermals and Power

Operating at 1.2 V, the unbuffered non-ECC design draws minimal power and produces no extra heat beyond standard JEDEC limits. No heat spreader is fitted, so airflow in the NAS chassis handles cooling silently. The single rank 2Rx8 layout keeps electrical load low for stable operation across all four sockets.

What the Kit Changes

The package contains one 4 GB DIMM, raising total memory toward the 64 GB maximum supported by the platform. Faster modules will automatically clock down to 2400 MHz, so this stick sets the effective speed floor. Installing matched pairs is recommended to enable dual-channel bandwidth for heavier workloads.

Questions about this item

How do I install this 288-pin DDR4 DIMM into my QNAP TS-1273U, and what step is often missed?

Power off the NAS, open the chassis, align the notch on the module with the slot key, press firmly until the side clips click shut, then verify the system reports the full 4GB at 2400 MHz.

What maintenance or replacement will this CM512642400DIMM module need over time?

No scheduled maintenance is required; the module carries a limited lifetime warranty from Computer Memory Solutions, so a replacement would only be needed if a manufacturing defect appears.

What limit appears first when this 4GB DDR4 2400 CL17 stick runs under sustained load in a TS-1673U?

The 4 GB capacity ceiling is reached before any thermal or voltage limit, since the unbuffered module has no heat spreader and operates at the standard 1.2 V.
