When you run out of addressing space, you cannot use all of your ram.
What can I do to change that?
I am using WIndows 32 bit.
I have 2x eVGA GeForce 256MB 6800GSs in SLi, so I guess that contributes.
But I am using only 3 GB of RAM total, 1 GB of video RAM.
If it says I'm using 2.5 GB of RAM, 1 GB of video RAM...where did the other .5 RAM go when subtracting the difference from my total memory to my "addressing space?"
