OWC DDR4 SODIMM for TerraMaster NAS

This 8 GB DDR4-3200 CL22 SODIMM is built to JEDEC standards and validated for TerraMaster U4-423, U8-423 and U8-450 systems. The 260-pin unbuffered non-ECC module runs at 1.2 V and uses a 1Rx8 organisation. It replaces TerraMaster part A-SRAMD4-8G and installs without tools in the accessible memory slot.

Suitable for owners of listed TerraMaster models

Buyers with other NAS brands or TerraMaster units not named above should look elsewhere because the module is qualified only for the three specified models. Systems that require ECC or registered DIMMs cannot use this unbuffered non-ECC stick. The single 8 GB capacity also limits maximum density per slot.

DDR4-3200 CL22 1Rx8 260-pin SODIMM specification

The JEDEC DDR4-3200 PC4-25600 CL22 timing and 1Rx8 rank organisation decide whether this module matches the memory controller of the target TerraMaster NAS. Verify the system documentation calls for this exact speed, latency and rank before purchase.
