I currently have a QNAP 251D. I want to upgrade the RAM. Can I get any major branded DDR4 sodimm RAM to upgrade my NAS RAM or do I need specific brands or models for compatibility?
I recommend using Crucial memory if you want to go above Qnap recommended RAM size sticks. You can also go for other brands like Kingston or Samsung, just make sure you match the specs.
I hope this helps.
