TerraMaster NAS memory upgrade

This 32GB DDR5 SODIMM module is built for the TerraMaster F6-424 MAX, F8 SSD, F8 SSD PLUS, T9-500 PRO and T12-500 PRO. It targets owners of those systems who need more capacity for virtualisation, heavy file serving or multi-user workloads. The stick is unbuffered, non-ECC and runs at the standard 1.1V.

JEDEC DDR5 4800 CL40 2Rx8

The module plugs into a 262-pin SODIMM slot and operates at PC5-38400 speed with a CAS latency of 40. It requires no heat spreader and draws power at the JEDEC-defined voltage, leaving headroom for the system's own thermal design. No extra cabling, firmware steps or BIOS tuning are mentioned in the specification.

Sustained throughput for multi-tasking

Under continuous load the DDR5 architecture keeps bandwidth stable across the 2Rx8 organisation, letting the NAS serve concurrent streams without the dips seen in single-rank layouts. The 32GB capacity means larger working sets stay resident, reducing swap activity during prolonged backup or transcoding jobs. The part is validated to JEDEC and RoHS standards for long-term reliability.

Questions about this item

Does the CL40 latency limit bandwidth when the NAS runs sustained workloads?

The module runs at DDR5 4800 with CL40 timing, so latency is fixed by the JEDEC specification for this speed grade.

How much heat does the 1.1V SODIMM produce during all-day operation in a TerraMaster unit?

Operating at 1.1V without a heat spreader keeps thermal output low; the module is designed for continuous NAS use within standard SODIMM thermal limits.

Which TerraMaster models must I already own for this 262-pin DDR5 SODIMM to be compatible?

Compatible systems are TerraMaster F6-424 MAX, F8 SSD, F8 SSD PLUS, T12-500 PRO and T9-500 PRO.
