Win 7 not using all 8GB of Ram

Microsoft Windows 7 Ultimate 64-bit
CPU
AMD FX-8320 22 °C
Vishera 32nm Technology
RAM
8.00 GB Single-Channel DDR3 @ 666MHz (11-11-11-24)
Motherboard
MSI 760GM-P34(FX) (MS-7641) (CPU1)
Graphics
HP S2031 (1600x900@60Hz)
NVIDIA GeForce GTX 650

Graphics has 1GB of it's own memory, and Win7 is still reserving 4GB of my 8 for Hardware when it shouldn't be. My MB supports up to 16GB max; I tried changing the RAM around, I've tried setting it in Advanced boot settings. Nothing works Any help?

Do you have 2 sticks of 4GB RAM? If so try inserting one at a time. Check the RAM settings in the BIOS to the default.

MSI boards are sometimes goofy.
Try resetting your BIOS, (pull the battery, use the reset jumper, etc etc)...
Then run windows and see what you get.

It didn't work, still not allowing me to set boot with no max memory.

When you first start the computer you will see the number in the top left or right corner, unless you have some silly full screen picture that covers everything the bios is doing during startup.

It reactivated that when I reset the BIOS; I tried to just download the update and it said it wasn't compatible with my version of windows

Easiest way to update ur BIOS is to take that file you downloaded and stick it on a flash drive/usb stick and restart into the bios and I believe if you pick the menu in your BIOS that is the far right hand one, it will show a menu that is "update bios" and you pick the file on the USB flash stick and it will update itself.

Alright I'll try that

Take the A7641AMS.HE0 file and stick it on a USB flash drive and restart into BIOS and go to Utility and M-Flash and it should find that file and update itself.

I've updated it. It still say's 4GB usable; do I need to reset and try and give it specific boot instructions again?

It should automatically give you the full 8gb and windows should see almost all of that, there wouldn't be any settings that you can change that would change how much RAM windows would "see".
The only other thing I can think of is one of the sticks of RAM was bad, or the RAM or motherboard is incompatible/doesn't like each other. Other than the BIOS update, there is little you can do but swap your RAM sticks out for different ones and see if that helps, if it doesn't then more than likely something is wrong with the motherboard.

Almost forgot, you have onboard GPU right? and a second GPU video card right?
Try disableing the onboard GPU and use just the video card.

It's all brand new; Motherboard, Ram, Graphics, PSU. Completely new build.
It see's the ram it's just setting 4GB of it for "Hardware"

Hmm, that is strange.
Unfortunately I'm out of ideas, I can't find much on the boards that describe your problem either.
You can try swapping out different ram chips and see if that helps.
Other than that, bad motherboard.
Sorry I can't help you more.

Got it, not sure what it was but I got it. I took out the RAM put it back in one by one, tried different slots, made sure each slot worked properly, at first it wasn't loading with the second slot, and I thought it was that; but I got it working, it's possible the seating may of been loose or just needed switched around again cause I'm running 8/8 now. Thanks!

Maybe I shouldn't have spoke cause now I'm crashing 10 way's from sunday, and I don't know why it seems to of stabilized now but before it was crashing moment I loaded windows went into BIOS played a nice loud sound if internal windows music for me. I just hope it can stay stable.

I ended up trying to make it save an extra GB and now it's back to 4GB usable... I don't understand what's wrong with this thing..

Wouldn't have any idea on that, would you?
