I have a hp pavillion 15 e026-ax and i have dual graphics(ATI radeon HD 7660G and ATI radeon 8670M). piriform's app 'speccy' displays that the crossfire is disabled. How do i find out if it is true?
How to check the crossfire status??

What those cards do is not exactly crossfire. Some details here http/www.notebookcheck.net/AMD-Radeon-HD-7660G-HD-7670M-Dual-Graphics.81173.0.html
