Best RAM upgrade for the UGREEN NASync DXP4800 Plus

Best RAM picks for the DXP4800 Plus

Three sensible ways to spend, from a single stick to a full 32GB pair.

Which should you pick

Why RAM matters on this particular NAS

The DXP4800 Plus ships with 8GB of DDR5 as standard, which is workable for basic file serving but starts to feel tight the moment you add Plex transcoding, multiple Docker containers, or a busy multi-user household. The Pentium Gold 8505 handles hardware transcode for Plex and Jellyfin without issue, but that CPU headroom counts for little if the system is swapping memory because RAM is exhausted. Moving to 16GB is a sensible baseline for most users, and 32GB (the platform maximum) makes sense if you are running several containers, a Plex Media Server database, or using one of the two NVMe slots as a read cache alongside heavier workloads.

Because this model uses standard DDR5 SO-DIMM at 5600MHz or 4800MHz, you are not locked into an expensive proprietary module. Any of the modules listed above will physically fit and run, though matching speed and timings across both sticks (if you fit two) avoids the system defaulting to the slower module's rated speed. There is no ECC support on this board, so do not pay extra for ECC memory expecting it to be recognised or to bring any benefit here.

One honest caveat
