System RAM

Heya People

I'm just writing as i am abit confused about i've seen about my System RAM. I'm currently running 64bit windows 7 Professional, AMD 9500 Quad Core Processor, 2x GeForce 98000 GTX SLI'ed and 6Gb of RAM installed in my computer, but windows says only 4.75Gb of this RAM is usaable. Does this mean that windows cant access the other 1.25Gb of RAM from my computer indicating its broken or incompatable somehow, or does this mean that windows has allowcated that RAM to the running of windows itself or other programs, if so, will i be able to add more RAM to my system or will it be a waste of time and money.

Thanks for you help

If you are looking in task manager I think it means that the system is already using 1.25 to run.
