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.

What sets the DXP4800 Plus apart
The model putting Synology under pressure: 10-gigabit networking out of the box, up to 64 GB of RAM, four bays. To actually saturate the 10GbE link you need four quick CMR drives here or the NVMe cache, otherwise the drive is the limit, not the network.
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; on the DXP4800 Plus you simply match the SO-DIMM spec and standard sticks are fine. 64 GB per the manufacturer

Frequently asked questions
What memory does the DXP4800 Plus use?
DDR5 SO-DIMM (2 slots), starting from 8 GB. 64 GB per the manufacturer It uses standard non-ECC modules.
Can the DXP4800 Plus's memory be upgraded?
Yes. The DXP4800 Plus has 2 slots, officially to 64 GB.
Is more RAM worth it in the DXP4800 Plus?
Yes if you virtualize. The DXP4800 Plus's Intel Pentium Gold 8505 (5 cores, 6 threads) can run several VMs and many containers, and those are what use the extra memory; for plain file storage the stock 8 GB is enough.
Can I put third-party drives in the DXP4800 Plus?
Yes. UGREEN locks no drive brand on the DXP4800 Plus — its compatibility list is guidance, not a gate — so any CMR NAS drive works.
