8.00 Ram (3.20 usable)

I have 8 GB of RAM, but only 3.2 is usable. It used to be way more than that, what went wrong?

Sounds like you have the 32 bit version of Windows 8.1 instead of 64 bit.

Right click on This PC and select Properties, what does it show:

it says 64-bit Operating system, x64 based processor

Bump!

Post a picture of Resource Monitor. Memory tab.

Open Task Manager, Performance.
Click on Open Resource Monitor at the bottom.
Click on the Memory tab.

Should look something like this:



What is the Hardware Reserved value?

Here is the Resource Monitor. Nearly 5 gigabytes is being used for hardware. Any idea on how to change that?

have the same problem here 4gb ram but only 3.57 usable

The amount of hardware reserved memory either defined in the BIOS/EUFI settings and/or in the system configuration (msconfig).

If you can, update your BIOS/EUFI to the latest version and check how much memory is allocated for the "AGP video apperture" (this could be called something different, depending on your system's BIOS). Try to lower this value, you can always change it back if you have issues.

In the "msconfig" window (run it as admin), check the advance setting under the "Boot" tab. If the "Maximum memory" is checked, uncheck it. Windows will allocate memory as the hardware needed, but you can also put back the check mark if you experience issues.

Both Intel and AMD CPUs with integrated GPUs reserve memory in the BIOS/EUFI and possibly in Windows, if the drivers/software package is installed.

32 or 64 bit OS? Sounds like 32 so 3.57 is normal.

Check BIOS and see if you have a setting for Memory Hole Remapping. If yes, try setting it to Disable. Save and reboot and see what ram usage looks like.
