Single 32 GB DDR5 SODIMM

This 262-pin DDR5 module delivers 32 GB of memory at 4800 MT/s with CL40 latency and 1.1 V operation. It is built for TerraMaster NAS units including the U12-500 PLUS, U4-500, U8-500 PLUS, T12-500 PRO and T9-500 PRO.

Check slot count and maximum capacity

Verify how many SODIMM slots your TerraMaster model provides and what total memory it supports before ordering. The module is non-ECC and unbuffered, so it must match the platform's memory architecture.

Steady throughput for multi-user NAS workloads

Under sustained load the JEDEC-standard DDR5 4800 interface maintains consistent bandwidth for concurrent file transfers, virtual machines and container workloads. The 2Rx8 organisation helps keep latency stable during prolonged multi-threaded activity.
