My son's computer had two 8GB RAM stick installed, but Windows 10 is only reading them as 4GB each. What's the issue here?

64bit OS

The BIOS shows also as 8GB

What I am really trying to find out is if the RAM is bad, or if it's the motherboard.

Running memory diagnostics tool now. - Checked out.
