Best RAM upgrade for the UGREEN NASync DXP4800

RAM picks for the DXP4800

The DXP4800 has two SO-DIMM slots and a hard 16GB ceiling, so every sensible pick here is an 8GB stick to add alongside the factory module.

Which should you pick

Why 16GB is the ceiling, not a limitation to fight

The DXP4800 runs an Intel N100, a quad-core chip built for efficiency and light-to-moderate workloads rather than heavy virtualisation. UGREEN caps this board at 16GB DDR5 across its two SO-DIMM slots, and that ceiling is a hardware limit, not a firmware restriction that might lift later. Buying anything beyond a single 8GB module to pair with the stock 8GB is wasted money, because the board simply will not address more.

In practice, 16GB is plenty for what this NAS is designed to do: file serving over its dual 2.5GbE ports, Plex or Jellyfin with hardware transcoding taking the load off the CPU, and a handful of light containers or a Time Machine target. If you are finding 16GB tight, the bottleneck is more likely the N100's four cores than the memory, and no RAM purchase fixes that.

Matching speed and timings to the existing module matters more than chasing the fastest kit on the list. Since the DXP4800 ships with a single 8GB DDR5-5600 SO-DIMM, buying another 5600MHz module keeps both sticks running in harmony rather than the system downclocking to match the slower one.

One honest caveat
