DDR5 4800 SODIMM for TerraMaster NAS

This 8GB DDR5 4800 CL40 SODIMM module is built for the TerraMaster F6-424 MAX, F8 SSD, F8 SSD PLUS, T12-500 PRO and T9-500 PRO. It installs as a single 262-pin unbuffered non-ECC stick running at 1.1V. The upgrade adds memory capacity to those specific NAS appliances.

Suits owners of listed TerraMaster models.

The module is validated only for the TerraMaster units named in the compatibility list. Buyers with a different NAS, laptop or desktop should look elsewhere because the firmware and slot keying may reject this part. Systems requiring ECC or registered memory cannot use this unbuffered non-ECC stick.

8GB single-rank DDR5 4800 CL40 at 1.1V

The decisive specification is the 8GB capacity combined with DDR5 4800 speed, CL40 latency and 1.1V operation in a 1Rx8 layout. If your TerraMaster model accepts this exact density and timing, the module will work; if it needs a different capacity, speed or voltage, it will not.
