OWC 16GB DDR5 4800 CL40 1Rx8 262-pin 1.1V SODIMM for TerraMaster U12-500 PLUS U4-500 U8-500 PLUS

16GB DDR5 4800 SODIMM for TerraMaster NAS

This 16GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1V operation. It fits the TerraMaster U12-500 PLUS, U4-500 and U8-500 PLUS as a direct memory upgrade. The unbuffered non-ECC design matches the factory specification for these NAS platforms. Builders who need ECC error correction or registered DIMMs cannot use this module.

Thermals noise and power draw

The SODIMM operates at the standard 1.1V DDR5 voltage without a heat spreader. Passive cooling inside the TerraMaster chassis keeps the module within JEDEC thermal limits during typical NAS workloads. Power draw scales with the 4800 MT/s data rate and single-rank 1Rx8 organisation. The module adds no audible noise because it has no moving parts.

Sustained load behaviour

Under continuous file-serving or virtualisation tasks the memory maintains its rated 4800 MT/s speed and CL40 timing. JEDEC-compliant signalling ensures stability during extended multi-threaded access across the 262-pin interface. The single 16GB rank simplifies the memory controller load compared to dual-rank alternatives. Workloads that exceed 16GB of physical memory will still trigger swapping to storage.
