TerraMaster NAS Memory Upgrade

This OWC DDR4 SODIMM delivers 8 GB of system-specific memory for TerraMaster F2-223, F2-423, F4-223, F4-423 and T12-423 units. It installs as a single 260-pin module running at 3200 MT/s with CL22 latency and 1.2 V operation. The non-ECC, unbuffered design matches the factory specification for these NAS platforms.

Replaces Original 8 GB Module

The module directly substitutes TerraMaster part number A-SRAMD4-8G when the factory stick fails or when a vacant slot needs filling. JEDEC compliance and ROHS certification keep the upgrade warranty-safe for the NAS chassis. The jump is worth it when the system shows memory pressure during file transfers or container workloads.

Sustained Load Behaviour

Under continuous operation the module maintains rated DDR4 3200 speed without a heat spreader, relying on the NAS chassis airflow for cooling. CL22 timing remains stable during extended multi-user access or background scrubbing tasks. The 1Rx8 organisation provides consistent throughput for the supported TerraMaster models.

Questions about this item

Will this 260-pin SODIMM fit the memory slot in my TerraMaster F4-223?

Yes, the module uses the standard 260-pin DDR4 SODIMM form factor required by the F4-223 and the other listed TerraMaster models.

What is the correct way to seat the module so it locks in place?

Align the notch with the slot key, insert at a slight angle, then press down firmly until both side clips click — the step often missed is pressing evenly on both ends until the clips engage.

Does this 1.2V non-ECC stick need any firmware update or pairing to keep running reliably?

No firmware or pairing is required; it is a JEDEC-standard 1.2V unbuffered module designed to run at the rated 3200 CL22 settings for the life of the NAS.
