When I used to use integrated graphics on my AMD A-9600 I assumed that my memory only stated that 6GB of the 8 (2400MHz) inserted was available because I was using integrated graphics and the APU was using the RAM as its VRAM, however now that I’ve plugged in my GTX 660 it still shows up at 6GB available in my task manager. Is this normal or do I need to do something to start using my VRAM instead of RAM?
