I have a Dell Inspiron 15R SE (7520). It comes standard with AMD 7730m have used msi afterburner to push 7730m CORE from 575mhz to 680mhz and MEM from 900mhz to 1000mhz. It has 1080p screen so the card has to work hard to get playable FPS but temps sit around the 63 degree mark. I cant find any way to increase the voltage it there any way to do this???? I understand the risks of meddling with Notebooks =D
