My computer says "4.99 GB Usable" HELP!

[lackjack5]

I recently got my 8gb ram and then i went to check my computer specs and i saw something weird.

It of course said 8.00 GB ram but right next to in in parenthesis it said (4.99 GB Usable)

What does this mean and what do i need to fix?

Is my computer wrong should i use a different software to check?

2. I pressed the 'Computer' button
3. I right clicked 'Computer' in files explorer
4. I clicked properties in 'Computer'

Is it Windows 7 32bit or 64bit?

Run msconfig exe / Boot / Advancced options and see if the max memory is limited there. If yes, delete that.

CPU-Z only read the SPD information and doesn't check if the memory is usable. The Windows Event Viewer might show additional information around the boot time.
