I want to upgrade the memory for this desktop from 4GB to 16GB. I do understand that I have an Windows 32 bit version which I should upgrade before my RAM is upgraded.

I would like to know if the mother board supports 16GB RAM or not? If YES then which RAM is applicable (DDR4 or DDR3)? Will this have any implications on my PC?

If 16 GB RAM is not supported then how much RAM can I get this upgraded to? The RAM currently I have is from Samsung.
