Best RAM for the UGREEN NASync DH4300 Plus
By Devin Chua · Data checked by Owen Nakamura · Updated The UGREEN NASync DH4300 Plus's 8 GB (LPDDR4X, soldered) is fixed to the board and cannot be upgraded, so you choose this once at purchase. The ARM 8-core (Cortex-A76 and A55, 2.4 GHz) is an ARM file-server chip that would not use much more anyway: for file storage and backups the 8 GB is enough, and if you need headroom for containers or VMs, a model with memory slots is the answer.

What sets the DH4300 Plus apart
The affordable ARM version with four bays. The memory is soldered, so you decide once and for good at purchase: 8 GB stays 8 GB. That is exactly why the DH line is a file store, not a container platform.

Frequently asked questions
What memory does the DH4300 Plus use?
LPDDR4X, soldered, starting from 8 GB. Soldered, not upgradeable It uses standard non-ECC modules.
Can the DH4300 Plus's memory be upgraded?
No. The 8 GB is soldered to the DH4300 Plus's board and cannot be changed — a decision you make once, at purchase.
Is more RAM worth it in the DH4300 Plus?
Rarely. The DH4300 Plus's ARM 8-core (Cortex-A76 and A55, 2.4 GHz) does light file-server work; the stock 8 GB covers file storage and backups, and the chip would not make much of more.
Can the DH4300 Plus run Plex with hardware transcoding?
Only in software. The DH4300 Plus's ARM 8-core (Cortex-A76 and A55, 2.4 GHz) has no Quick Sync, so Plex transcodes on the CPU — enough for direct play, not for heavy 4K transcoding.
