Compatible TerraMaster NAS upgrade

This OWC 16GB DDR4 3200 SODIMM is built for TerraMaster U4-423, U8-423 and U8-450 units. It matches the original 260-pin 1.2V Non-ECC specification exactly. The module installs in the available memory slot without tools. Buyers using other NAS brands or desktop boards cannot use this part.

JEDEC and ROHS compliant module

The stick meets JEDEC PC4-25600 timing at CL22 and carries ROHS certification. OWC tests every unit in-house and backs it with a limited lifetime warranty plus free technical support. No extra software, drivers or heat spreaders are included in the package.

16GB single-module capacity

One 2Rx8 rank delivers 16GB of addressable memory for the compatible TerraMaster models. The system can run multiple containers, virtual machines or large file caches at DDR4 3200 speed. Workloads that need more than the installed slot allows will require a higher-density module not offered here.

Questions about this item

Will the CL22 timing require any future adjustment or replacement?

The module runs at JEDEC-standard CL22 with no user-adjustable timing, so no maintenance or replacement is needed for the latency setting.

What limit appears first when the U8-450 runs this 3200 MHz kit continuously?

The DDR4 3200 JEDEC specification and 1.2 V voltage define the sustained operating envelope; no higher speed or lower latency is supported.

How much heat and power does the 1.2 V SODIMM produce during all-day operation?

At the standard 1.2 V DDR4 level the module generates minimal heat and draws low power, requiring no extra cooling in the TerraMaster chassis.
