ASK NC

Hi, I would like to increase the RAM in my 251D from 2GB to 4GB by inserting another 2GB stick, but must I buy the expensive QNAP RAM for this, or can I buy, the MUCH cheaper, RAM from somewhere else, as long it has the same specs of course? Thanks

Yes, I recommend Crucial RAM.I have prepared a guide here: https://nascompares.com/ram/qnap-ts-251d-compatible-ram-memory-upgrade/I hope this helps.
