Windows 7 not using all RAM

[CpuFixrMan]

As Disco said. Regardless of what the CPU is, unless you installed a 64-bit version of Windows 7 the most you will get is about 3.2GB usable to the OS.

I know you said 64-bit..... Just double checking.

When you right click on my computer and select Properties, under system it says:

"System type: 64-bit Operating System"

I've seen people who had 64-bit capable procs load 32-bit versions of windows and get confused.

Are you using windows 7 pro? Home edition might not utilize all ram.

newegg shows that other people are having the same problem with your motherboard

When you say "only 3GB is usable", how do you determine that?

I have 6GB of RAM installed and system recognizes it however there is only 3GB usuable. I have tried going into msconfig => system config => boot tab => advanced options => unchecked the "maximum memory" option" but it still doesn't work for me. I've also gone into the BIOS and don't see anything there as well.

My build is Windows 7 (64bit), 6GB Cosair RAM, MSI X58A-GD45 motherboard, 2 x Sapphire 1GB 5770, intel i7-950, etc...

Memtest? Maybe it's dead..
