OWC 32GB (2x16GB) DDR4 3200 CL22 SODIMM for TerraMaster U4-423 U8-423 U8-450

32GB DDR4 SODIMM kit for TerraMaster NAS

This OWC kit supplies 32GB of DDR4 memory as two 16GB unbuffered SODIMMs rated at 3200MHz CL22. It is built specifically for TerraMaster U4-423, U8-423 and U8-450 models and runs at the standard 1.2V without ECC or heat spreaders. The modules use a 2Rx8 rank configuration on 260-pin DDR4 form factor.

Sustained throughput at PC4-25600 speed

At the rated PC4-25600 data rate the pair delivers consistent bandwidth for multi-user file serving, virtual-machine hosting and container workloads on the target NAS units. JEDEC compliance means the sticks operate within the platform's validated timing envelope so performance does not degrade during extended transfers or background scrubbing tasks. The dual-channel population keeps both memory channels active for balanced load distribution.

Low-voltage operation with no active cooling

Each module draws power at 1.2V and produces minimal heat because no heat spreader is fitted and the NAS chassis provides passive airflow across the SODIMM slots. Acoustic impact is zero since the memory adds no moving parts and the system fans do not need to spin faster to compensate. Power draw stays within the platform's original memory budget so the upgrade does not affect the unit's overall efficiency.
