Windows 10: I have 8GB of RAM but only showing 4GB

I have had my PC for about a month now and I have noticed my game felt choppy but I was still getting 180fps like usual. I checked nvidia and it was all fine so I checked how much memory I was using and it says 3.7 of 4GB. I still have both 4GB RAM sticks in but one isn't being used. How do I fix this as I should be using 8GB of RAM.

Windows shows 8GB RAM installed but 4GB RAM is usable

Hi There,

I've just upgraded my pc from 4GB RAM to 8GB RAM. Windows seems to have detected this upgrade but why does it show as only 4GB RAM available. The following is what I have tried so far with no luck:

• I have tried the msconfig method on ensuring maximum memory is not checked.
• physically removed the new RAM and reinstalled it

Any thoughts/suggestions on how i can resolve this matter?

Thanks

 

system shows 4gb usable instead of 8gb

System specs show 4gb ram but I have two 8gb ram sticks installed. How do I go about using the full 8gb on both sticks?

RAM shows 4GB hardware reserved insted of 8GB

Still no reply. Having the same issue. 8gb installed windows hardware reserved 4gb so I only have 4gb that i can use. installed 16gb or ram. windows has now hardware reserved 8gb of ram. Regardless of slots used. 3 different types of memory in as many
configurations as possible. all returning the same result. What the **** is going on. this has randomly happened on a healthy working install of windows 10. Have since done a fresh install with the same thing still happening....
