3.45GB usable with 6GB RAm in Windows 8.1 (64bit) help.

[PsychSC2]

I have tried all the things to do like going to msconfig to untick the memory and max processors. I already switched the slots of my RAM and still I don't get passed the 3.45GB usable of my 6.00GB RAM.

Before I did an upgrade of my mobo. I had the Emaxx EMX-MCP61D3-iCafe with Windows 7 64bit as my OS and I was able to get the full 6.00GB RAM.

Now when I upgraded my mobo to the Asus F2A85-M LE since I upgraded my CPU to the A8-5600k APU, I installed Windows 7 and thats where I got a 3.99GB usable. I was fine with since I used dual graphics with my HD7750 with my A8 APU.

But now to get to the point, its really a waste to not use the extra RAM memory that I have.

I have a Kingston DDR3 2GB and an EMAXX DDR3 4GB RAM.

Any kind of help or other advises is really appreciated. Thank you.

It could be that the memory channels are just not seen properly. Basically you should use the same sized memory modules in the slots. So probably if you had two 4 GB modules the machine would correctly see 8GB of it.

How to set the channels properly? I apologize for this stupid question, this is really basic for us enthusiasts, it's only I'm not really good with setting it up in bios and stuff. My apologies. xD

You can't with the current hardware. You would need a 2nd 4GB memory module like the other one.

Is there an explanation why I was able to get the full 6.00GB ram with my previous motherboard? EMX-MCP61D3-iCafe. I was using Windows 7 64bit at that time.

Your ram is single channel and that motherboard is designed dual. Probably a compatibility issue.
