Windows 10: New 16GB RAM only 3.9 GB usable

I just installed a 16GB ram into my computer and its showing only 3.9GB usable. I have been looking for solutions on how to fix this issue. Let me know if you need anything else. I'm not really an expert with computers. I just want to play Modern Warfare with stable frames!

I have AMD FX 8350 Eight Core Processor on a Windows 10 64 bit computer.

4gb RAM but only 3.47 gb usable


Hi, I have an ASRock H61M-VG3 Mother board with a maximum RAM amount of 16gb. I have 64bit Windows 10 Pro. I have 4gb of RAM but only 3.47 gb Usable. Does anyone know how to help because I would like it fixed because I am upgrading to 16gb Ram, and it would be ridiculous to have 16gb of RAM but only 3.47gb Usable.

 

Installed RAM 16GB (7.18 usable)


I downloaded CPUZ. Here are the screen shots:

Thanks for the advice, hope this helps resolve this issue.

 

Why 2.66 GB usable in 4 GB ram?

Thanks to everyone for their valuable suggestions. I guess the problem was with the OS.Because after increasing my ram from 4 gb to 8 gb still the usable memory was 2267 mb out of 8 gb, then I did a clean install of Windows 7.Now everything is fine and smooth, and usable memory is 7.9 gb out of 8 gb.
