So, today i've installed my 2 Hd7770s in crossfire on my Asrock Extreme 4 970 motherboard. (Amd phenom II x6 1090T processor) In certain games i'm experiencing immense lag, for example CS:Go and LoL.

Do i have to set anything else up besides that CCC activates it automatically?

You must enable Crossfire if you haven't already.

AMD CCC asked something for crossfire, if it isn't the only option where do i need to enable it?

I have no experience with CCC. If you didn't explicitly enable it, check to make sure it is enabled in CCC.

Honestly I don't even know if the 7770's support crossfire do they?  I only thought it was the 78xx and 79xx series that supported crossfire.

 

even so, its just a switch in CCC.  Once you enable it, poof it should work as long as the game supports it.

Please spend as much time writing your question, as you want me to spend responding to it.  Take some time, and explain your issue, please!

I've enabled crosfirex for applications that do not have profiles. not much difference.

 

And they should indeed be elligible for crossfire, why would they otherwise put a connector on the top D;

What games have you tested?

Run valley benchmark, or have any gpu monitoring software open and see if both are under load while gaming
