UGREEN NASync DH2300 RAM: upgrade limits and alternatives
By Devin Chua · Data checked by Owen Nakamura · Updated The UGREEN NASync DH2300's 4 GB (LPDDR4X, soldered) is fixed to the board and cannot be upgraded, so you choose this once at purchase. The Rockchip RK3576, ARM 8-core (Cortex-A72 and A53) is an ARM file-server chip that would not use much more anyway: for file storage and backups the 4 GB is enough, and if you need headroom for containers or VMs, a model with memory slots is the answer.

Is 4 GB enough on the DH2300?
For what this model is built to do (file serving, device backups and everyday storage), yes. RAM on a NAS is mostly a disk cache, not a speed dial: the UGOS Pro system and its file services run comfortably in 4 GB, and the Rockchip RK3576, ARM 8-core (Cortex-A72 and A53) would not do meaningfully more with extra memory even if it had a slot. Where more RAM genuinely earns its keep is heavy multitasking (running many Docker containers, virtual machines, or ZFS, which uses memory as a read cache) and the DH2300 is not built for any of those.
Because the memory is soldered, this is a buy-once decision with no upgrade path. If you already know you want a container or virtual-machine platform, choose a model with SO-DIMM slots instead: the drives-by-model index shows which do, and how much RAM a NAS needs sets out the real requirement by workload. For its intended job the DH2300’s fixed 4 GB is not the wall you hit first: capacity is, so put the planning into the drives with the drive calculator and the live CA$/TB table for the DH2300.
Drive policy: UGREEN locks no drive brand on the DH2300; its compatibility list is guidance, not a gate. The DH2300’s full compatibility rules.
Keep calculating
To see how much capacity is left after parity, the DH2300 capacity calculator is preset to its 2 bays and RAID types. For the DH2300, the wider basics of choosing a drive are in the buying guides, and CMR versus SMR explains why SMR drives do not belong in a RAID array.

Frequently asked questions
What memory does the DH2300 use?
LPDDR4X, soldered, starting from 4 GB. Soldered, not upgradeable It uses standard non-ECC modules.
Can the DH2300's memory be upgraded?
No. The 4 GB is soldered to the DH2300's board and cannot be changed: a decision you make once, at purchase.
Can the DH2300 run Plex with hardware transcoding?
Only in software. The DH2300's Rockchip RK3576, ARM 8-core (Cortex-A72 and A53) has no Quick Sync, so Plex transcodes on the CPU: enough for direct play, not for heavy 4K transcoding.
