So I have a lenovo y510p and I was wondering if sli is automaticky enabled or do I have to manually turn it on, I notice a lot of people saying how hot it gets and it hasn't for me so it leads me to think sli is off and I've never done anything in the settings (to turn it on or otherwise) so is it on and I'm just lucky or do I have to enable it
Ps. I have windows 8
