dumb question for crossfire

post #1 of 5
Thread Starter 
how do you overclock? does changing speeds in afterburner automatically do it to both cards?

Not a dumb question at all, a very good one. Card 2 will defult to card 1s clock. Say i got 2x 5850s.

5850 1: 800mhz
5850 2: 820mhz

5850 2 will underclock to 800mhz.

Now, for a OC, you can overclock both cards in ATI overdrive, easy. you need to be stable on both cards.

5850 1: 850mhz
5850 2: 850mhz

All goood!

it can be set to do it if u make the slave sync with the master bringing the main one will bring the other one up too

if u see the second card having low shader clocks and **** its normal once you go into a game it will boot up to what u set it
