Very Low Usable RAM AGAIN

[FelixCSGO]

So in my last post I had an HP machine that was using 7.70GB of 10GB in Windows 8. Well I recently upgraded to a Gigabyte GA-970A-D3P. The first time that I got the mother board, it was a bad board. USB ports weren't working half of the time, and then it would randomly restart. I sent the board in for RMA, and I got a new one. But now I installed everything correctly, and My PC is only using 3.97GB of the 10GB that I have installed. Here are some screenshots. Please help.

is there any chance you got thermal paste on one of the pins on your cpu or that there was dust in your socket? It is not uncommon for that to cause this issue.

Nope, the entire build went smoothly. Execpt for not being able to use all the ram...

[Altecice]

There was a BIOS update that addressed some DRAM issues, Have you checked that you are on the latest BIOS?

What speed of RAM are you using and is it in the QVL of the motherboard/CPU?

[FelixCSGO]

The speed of the ram is 1600Mghz I didn't have this problem the last time. Should I try, and update the bios?

In which slots are the DIMMs?

[FelixCSGO]

The slots are farthest away from CPU so it goes 4X2X4

I have the same problem, 8.5GB of my 16 GB was "hardware reserved" a few days later I simply removed them from the slots and put them back in and now it's only about 50MB. I'm still not sure what the problem is myself but I know that I've seen a lot of people have similar issues.

This might be the answer to my problem, I only had this problem after taking them out to clean out the dust in my computer, which I did a less than perfect job on as I did not have the proper tools. I'll try to see if there's any dust in the socket later.
