Computer Memory Solutions CM512642400DIMM 4GB DDR4 2400MHz CL17 1.2V Non-ECC DIMM memory upgrade

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.
