I just got a new build going, but for some reason under System Information it says I have 8GB of installed memory but 2.92GB usable? Does anyone know why this is? How do I get the full 8GB?
 
If you have only a 32bits OS, you can use 4GB max but you also need to carve out chunks of it for memory-mapped IO for the video card and other devices, which may be how you end up under 3GB.

In that case, the only thing you can do is upgrade to a 64bits OS.
