What type of system? 32 or 64 bit?
ah right i should have mentioned its a 64 bit.

Did you build this computer? What type of motherboard, RAM? Is this tri-channel? What have you tried?

What's OS? Windows 7 presumably. More info needed!

Just to confirm...
Is all of the RAM recognised by the BIOS, and it's Windows not recognising it or is it not recognised by the BIOS either?
Just as an obscure option try msconfig > boot > advanced options > check that there's no "Max Memory" option set.

This is a really common problem on the i7 platform.
i would ... remove memory and re set it one stick at a time. power on the PC each time you add a stick of RAM. also, you need to check the bios and look for the voltage and timings to make sure they are set correctly. Some times the bios will set these incorrectly.
Sometimes When enabling 3 Channel mode with three memory modules, be sure to install them in the
DDR3_1, DDR3_3 and DDR3_5 sockets I would do the above first.

Display FULL system specs. Also, download CPU-Z and take a screen shot and upload it here for me to see

Of course it's not the max memory boot option thing. Why would it be? It's unchecked by default and it went to 2GB usable when he reseated the hardware. So, let's think about what we have here;
We have a newly built system that has a processor with a common ram issue. We have the builder not really giving us much info at all, simply asking for shots in the dark to fix a problem that could have been googled for hundreds of answers. We have no information about if the ram was tested individually, using memtest. We don't have any information about what the user has tried themselves (like perhaps apply a bios update?).
This is basically an exercise in futility, as it is. SO....let's rule some things out, shall we?
First. The processor issue is likely not the issue, because it's recognized in the bios. That issue is usually a result of bent pins on the cpu socket that results in the ram not being detected in the bios at all. It should still be checked.
Second. The ram needs to be tested individually to make sure that each stick is good. Memtest should have already been used to verify in case a defective ram stick is gumming up the works.
Third. Has a bios update or anything else been tried? (V1 of that board has a bios update that addresses memory problems.) Have you looked up any information about setting the ram timing or voltage?
There's probably a "Fourth", too...but honestly I just don't care enough to go on.

I ran into this problem on my gaming machine at home. It is currently running windows 7 ultimate 64bit. If I'm not mistaken there is a little tweak inside the OS that you have to make for it to see everything. I'll have to look into it further when I get home. But do some research and check around on google.
