Am confused about this, my computer reads 8GB of ram however only 4GB is available this copy of windows is indeed x64 so don't understand. I want to upgrade to 16GB of ram soon with a better speed rating/CAS latency however am worried about this problem of my computer not utilizing its full potential.

If you need any additional information just ask, thanks your help is appreciated!

Quoting from this thread: http://www.tomshardware.com/forum/275873-30-memory-please-read-posting

Q: My system does not recognize the full capacity of the modules I installed. How do I fix this?
A:
1. If the system memory appears to be off by several megabytes, then check to see if you have an on-board graphics processor on your motherboard. Often, on motherboards with integrated VGA, a portion of the system memory, such as 8MB, is placed aside for video memory.
2. If the system is recognizing only a fraction, such as 1/2 or 1/4, of the total capacity of the module, then the problem is most likely due to you using modules with memory chips that are too high in density. Many older systems require lower density memory parts. As memory modules with higher megabytes are developed, the density of the memory chips also must increase. Older, lower density memory parts are phased out and become harder to find. Current modules with high density memory components may not work with the older systems.

Also, Windows 7 32-Bit OS has a max memory limit of 4GB. So if you are using Windows 7 32-Bit OS then that is the reason behind the issue.

Hope this helps you. :)

Not too sure about this, in my settings they're defaulted so no set number of processors or memory. And my computer is using all four processors as of now so not sure why the same is not for the memory as well.

The above is irrelevant to my post, as I stated earlier I am running x64 and as per the question and graphic I provided this isn't related to small portion of memory being unaccountable. Rather 4gigs of memory, however to elaborate the on board graphics unit is disabled as per my boot settings which automatically loads PCI as the priority bypasses the on board unit so it would have no effect. The system I am using is relatively old in regards to industry standards however isn't quite an antique as of yet, the mobo (h57m01) /ram (DDR3, 1333 MHz DIMM)/processor (i5 - 2.67) is 5 years old. New PSU, GPU, and drives.

Pfffft, found this a tech bulletin on Microsoft site after I noted this was due to the Hardware Reserved portion of the graphic. Have program the memory outputs myself, thanks iJack you were onto something however in order for it to work I had to check the box xD
