OWC 16GB DDR4 3200 CL22 2Rx8 288-pin 1.2V Non-ECC UDIMM for TerraMaster U12 U16 U24

SKU CH-MBM6-S6A44

16 GB DDR4 3200 CL22 UDIMM module for compatible TerraMaster NAS models

  • Capacity16GB
  • Type288-Pin DDR4 Non-ECC UDIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.2V
  • ECCNo

Capacity 16GB

  • 16 GB capacity expands NAS memory for heavier workloads
  • DDR4 3200 speed with CL22 latency keeps data flowing smoothly
  • 2 V low-voltage operation reduces power draw and heat
  • 288-pin unbuffered non-ECC UDIMM fits TerraMaster U12 U16 U24 bays directly
  • JEDEC and RoHS compliant build ensures warranty-safe upgrade

TerraMaster NAS memory upgrade

This 16GB DDR4 module is built for TerraMaster U12 U16 U24 series NAS units. It fits the 288-pin UDIMM slots in models U12-322-9100 U12-722-2224 U16-322-9100 U16-722-2224 and U24-722-2224. The stick runs at 1.2V without ECC or a heat spreader.

Replaces TerraMaster A-URAMD4-16G

It steps in for the original TerraMaster part number A-URAMD4-16G with matching JEDEC CL22 timing. The upgrade is worth it when the NAS slows under concurrent file transfers or virtual machines. Backward compatibility covers 2133MHz 2400MHz 2666MHz and 2933MHz buses.

16GB single-module capacity

One 2Rx8 rank delivers 16GB of addressable memory for multi-user SMB shares and Docker containers. Headroom ends when total installed RAM hits the chassis limit or when workloads demand ECC protection. Non-ECC design suits the listed TerraMaster platforms only.

Questions about this item

Does the 288-pin DDR4 UDIMM fit the TerraMaster U12-722-2224 memory slots?

Yes, the module is a standard 288-pin DDR4 UDIMM and is listed as compatible with the TerraMaster U12-722-2224 among other U12, U16 and U24 models.

What is the correct orientation when inserting the CL22 2Rx8 module into the NAS?

Align the notch on the module's gold edge connector with the key in the slot, press down firmly until both side latches click into place, and verify the module sits level.

Will the 1.2V non-ECC memory need any firmware updates or replacement after installation?

No firmware update is required; the JEDEC-standard 1.2V non-ECC UDIMM is designed as a warranty-safe upgrade with a limited lifetime warranty and no scheduled replacement interval.
