8GB Installed 3.97 Usable


Ever since i built my computer a year ago I've had this problem where i have 8.00GB of Ram but only 3.97GB Is Usable.


I have a Legitimate copy of Windows 7 64-Bit Home Premium so that should not be the problem.
Memory Remapping is not an option in my BIOS Either :c

Here is a full list of my computer specifications.

More about 8gb installed usable
  1. Get Cpu-z, run it, click the about tab, choose "save report (.txt) and post the results here...
  2. Run DxDiag and check if you can run Dxdiag 64-bit and check your ram from there.
  3. also run memtest

    a faulty ram module can cause those exact symptoms
  4. i see nothings wrong with the exception of your problem, can you run msconfig?
    Win+R > Msconfig > Boot > advance options > untick maximum memory or tick it and set it to your max?
  5. Did not work either O_O

    If that doesn't help, try changing slots...but I believe something in your system is "reserving" RAM. Can you run your mobo without the graphics card as a test or is there no integrated video?
