Hello, I am having issues with my RAM not being used to it's full potential. I recently built this PC and have installed 2x DDR4 8GB RAM into it and the motherboard is a DDR4 board and supports this type of RAM. I am running Windows 10, and I have tried the 'msconfig' boot options multiple times and I still get the same issue. The only amount of RAM that is 'usable' is 2.1GB out of 16GB. Anyone know what is causing this issue?
