TerraMaster NAS memory upgrade

This OWC module adds 16GB of DDR4 3200 memory to compatible TerraMaster NAS units including the F2-223, F2-423, F4-223, F4-423 and T12-423. It uses the standard 260-pin SODIMM form factor and runs at 1.2V without ECC or buffering. The single-rank 2Rx8 design fits the memory slots in these specific models.

Sustained workload behaviour

The CL22 latency and 3200 MT/s data rate provide consistent throughput for file serving, virtualization and multi-user access over long periods. JEDEC-standard timings ensure the module maintains its rated speed without throttling during continuous read and write cycles. Unbuffered operation keeps latency predictable for the NAS operating system.

Thermals noise and power

Operating at 1.2V keeps power draw low inside the compact NAS chassis. The module has no heat spreader, relying on the system's internal airflow for cooling during normal operation. Silent solid-state construction adds no acoustic noise to the appliance. RoHS compliance confirms the absence of restricted hazardous substances.

Questions about this item

How much power does the 1.2V DDR4 module draw when the NAS runs continuously?

The module operates at 1.2V, the standard DDR4 voltage, keeping power draw and heat low during all-day operation in compatible TerraMaster units.

Which TerraMaster models accept this 260-pin SODIMM without extra parts?

It is validated for TerraMaster F2-223, F2-423, F4-223, F4-423 and T12-423; no additional hardware is required beyond an available slot.

Will this CL22 3200MHz stick work alongside the original TerraMaster A-SRAMD4-16G module?

Yes, it replaces the A-SRAMD4-16G and matches the same DDR4 3200 CL22 2Rx8 specification, so mixed populations run at the common speed and timing.
