OWC 16GB DDR4 3200 SODIMM for TerraMaster NAS

This 16GB DDR4 3200 CL22 SODIMM is built for TerraMaster T12-450, T6-423, T9-423, T9-450 and U12-423 units. It replaces the TerraMaster A-SRAMD4-16G part and runs at 1.2V without ECC. The module targets owners of those specific NAS models who need more memory for virtualization or heavy file workloads.

Tool-free slot access makes installation

The 260-pin SO-DIMM slides into the memory slot after removing the chassis cover. No heat spreader is present, so the module fits tight bays without clearance issues. The main risk is mixing capacities or speeds; OWC advises matching all installed DIMMs for optimal stability.

Single 16GB rank handles typical NAS duties

The 2Rx8 organisation delivers 16GB at PC4-25600 speeds, enough for multiple Docker containers or large ZFS caches. Capacity runs out when several heavy VMs run simultaneously or when deduplication tables exceed available RAM. Buyers needing 32GB or more must populate additional slots with identical modules.

Questions about this item

How do I confirm the module is running at DDR4 3200 CL22 after installing it in my TerraMaster T9-450?

Enter the NAS BIOS or use the TerraMaster OS storage manager; both will report the installed memory as 16GB DDR4 3200 PC4-25600 CL22 2Rx8 at 1.2V.

What ships in the box and do I need any extra parts for a TerraMaster T6-423 upgrade?

The package contains one 16GB 260-pin DDR4 SODIMM; no tools, brackets or additional cables are required for installation.

Which capacity should I choose if my TerraMaster U12-423 currently has a single 16GB stick and I want matched pairs?

Add another identical 16GB DDR4 3200 CL22 2Rx8 module to create a matched 32GB pair for optimal dual-channel performance.
