According to this video
https://www.youtube.com/watch?v=4bvIsI4QGEQ, it will accept 16 GB of RAM.
It apparently only has 4GB according to system properties and is running very slow under a Windows 10 64bit OS.
By the looks of the video, we may want to to have a shop put in the memory, but would like to come prepared with memory in hand.
We would like to buy two 8GB chips to give us the entire 16GB that it will take.
Suggestions for good pricing on memory for this particular unit and all the important specifications that are relevant to this unit are greatly appreciated.
