Best RAM for the UGREEN NASync DXP4800 Plus
By Devin Chua · Data checked by Owen Nakamura · Updated The UGREEN NASync DXP4800 Plus ships with 8 GB of DDR5 SO-DIMM (2 slots) and officially takes 64 GB. What benefits from the upgrade is specific to this box: the Intel Pentium Gold 8505 (5 cores, 6 threads) hardware-transcodes and runs containers, and those, not plain file storage, are what more memory feeds. UGREEN does not publish enough to confirm any module for it, so the modules below are listed as fitting physically but not confirmed by UGREEN, with what it leaves unstated.

Fit not confirmed by UGREEN
Physical fit for the DXP4800 Plus: DDR5 memory. Every module below matches that. UGREEN does not publish enough to confirm any of these for the DXP4800 Plus (UGREEN does not publish the module form (SO-DIMM or DIMM); a 2-module kit; UGREEN does not publish the slot count), so none is listed as compatible. Check the part against your unit, or UGREEN’s support, before buying.

What more memory buys on the DXP4800 Plus
The DXP4800 Plus takes DDR5 SO-DIMM (2 slots) up to an official 64 GB, across 2 slots, starting from 8 GB. Whether that upgrade earns its money is a question about this exact box: the Intel Pentium Gold 8505 (5 cores, 6 threads) is strong enough for concurrent VMs, and on a box like the DXP4800 Plus the memory ceiling, not the CPU, is usually what limits how many you run.
The DXP4800 Plus uses non-ECC DDR5 SO-DIMM (2 slots), so a flipped bit is not corrected. That is rarely a problem in practice, but it is why DIY TrueNAS builders insist on ECC. so match the generation, the module form and the size, and standard non-ECC modules are fine. 64 GB per the manufacturer
