#2 Can more RAM be added?
There is one ram slot on the motherboard of this device which is equipped with an 8gb stick of kingston ram. The other 8 GB are soldered to the mobo. You could theoretically swap the 8gb stick for a 16gb one, but you would lose the advantages of dual channel ram. I would also double check that the motherboard of this pc is capable of utilizing more than 16gb.
