Synology NAS 4 GB DDR4 module

This 4 GB DDR4 2133 UDIMM is validated for Synology RackStation systems needing a straightforward capacity increase. It targets administrators who want a single stick to expand memory without guessing compatibility.

No heat spreader or extra software included

The package contains only the memory stick itself, so installation relies on the NAS chassis airflow and the system BIOS for timing. There are no LEDs, spreaders or bundled utilities to configure.

Green PCB unbuffered stick

The 288-pin edge connector fits any DDR4 UDIMM slot keyed for 1.2 V operation. Absence of a spreader keeps the module low-profile for tight drive-bay clearances, while the 1Rx8 organisation ensures simple single-rank population.

Questions about this item

Will the CL15 timing on this DDR4 2133 module ever need adjustment or replacement?

The CL15 latency is fixed by the module's SPD profile and requires no maintenance; the memory itself has no moving parts and is designed to last the life of the system.

What limit appears first when this 1.20V UDIMM runs sustained workloads in a Synology NAS?

The 2133 MT/s data rate and single-rank 1Rx8 organisation set the bandwidth ceiling before voltage or thermal limits become a factor.

How much heat and power does this 4GB stick produce during all-day operation?

At 1.20V without a heat spreader, the module draws minimal power and runs cool enough for continuous NAS duty in standard chassis airflow.
