TerraMaster NAS memory kit

This OWC kit supplies 32 GB of DDR4 memory across two 16 GB UDIMM modules. It is built for TerraMaster U12, U16 and U24 NAS units listed in the compatibility table. The modules run at 3200 MHz with CL22 latency at 1.2 V.

Suits owners of compatible TerraMaster models

Builders who need ECC protection, registered DIMMs, or capacities beyond 32 GB cannot use this non-ECC unbuffered kit. Systems outside the listed TerraMaster part numbers should verify support before purchase.

3200 MHz DDR4 CL22 specification

The kit operates at DDR4 3200 (PC4-25600) with CL22 timing and 2Rx8 organisation. It is backward compatible with 2933, 2666, 2400 and 2133 MHz buses. This speed and latency combination determines whether the modules match the NAS memory controller requirements.

Questions about this item

What TerraMaster NAS models must I already own for this 32GB kit to be compatible?

This kit is validated for TerraMaster U12-322-9100, U12-722-2224, U16-322-9100, U16-722-2224 and U24-722-2224 systems.

Will the 3200MHz CL22 modules run correctly if my NAS currently uses 2666MHz memory?

Yes, the modules are backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds and will operate at the system's supported frequency.

How can I confirm the 32GB upgrade is recognised after installation?

Check the TerraMaster NAS information page or system BIOS; it should report 32GB total capacity running at the configured DDR4 speed.
