hi, i currently own a p45 biostar motherboard, im cinfused on what the jumpers are for? do they have something to do with setting crossfire? if no, how do u set crossfire? just plug in the second card?
Did you look in the manual?
There are 3 Biostar P45 boards. Which one do you have?
Perhaps you could share which Biostar P45 Mb you have? Have you read the manual yet? It has tons of useful information.
Crossfire should either be automatic or set through the BIOS.
