32 GB DDR5 4800 SODIMM for TerraMaster NAS

This 32 GB DDR5 4800 PC5-38400 module uses a 262-pin SODIMM form factor and runs at 1.1 V with CL40 latency. It is a JEDEC-standard, non-ECC, unbuffered 2Rx8 upgrade validated for TerraMaster F2-424, F4-424, F4-424 MAX, F4-424 PRO and F6-424 units.

Who this suits and who it does not

Owners of the listed TerraMaster models who need a single 32 GB stick to expand memory will find this module a direct fit. Builders whose systems require ECC, registered DIMMs, a different pin count or a voltage other than 1.1 V should look elsewhere.

Deciding specification: 262-pin DDR5 SODIMM

The 262-pin DDR5 interface at 4800 MT/s is the single attribute that determines compatibility; only platforms designed for this exact SODIMM type and speed can use the module.
