Often when I play Crysis 3, my computer comes with an error and says that the game takes too much memory. In the task manager i can uses more then 90% of my memory and often I can not do anything but press the reset button.

My computerspecs.:

and the 2 default 120mm intake fans with white led's in front
Graphics Card: Sapphire Vapor-X HD 7970 GHz 3GB
PSU: Corsair AX860i Digital

Max temp. while playing Crysis 3:

Can anyone tell me what's wrong??
