Hello,


I have a sapphire 5770 and an asus 5770 is it possible to crossfire them or do they have to be exactly same make and model?

Should work just fine... They will default to the lowest speed if it is different.

You can crossfire them just fine. You want them to be the same clock speed though otherwise you will get a few performance oddities.

If the cards are different speeds, and you want them both to run as fast as the fast one does, you can flash the firmware of the slow card to make it as fast as the other. You'd want to test it in single card mode at that speed for a while first, obviously. If it gets too hot you'll get problems.

I lost some monitoring abilities when I mixed two cards of different make together. One card didnt have all the same stuff as the other.
