Crossfire not working

So i just got a second Radeon 7970 but when i put them in crossfire they run worst than a single 7970. Why could this be?

Is it something with my motherboard?

 

Specs:

GPU : 2x radeon 7970 black edition 

CPU : AMD Phenom II X6 1075T

MOBO : Asus crosshair iv extreme

RAM : 12 gb

The right man in the wrong place can make all the difference in the world.

What game were you playing?

I can't even start Counter strike global offensive but i've played Star wars battlefront but its literally unplayable.

I've also tried Gmod, and GTA V but with same results

It should, and i dont get why its not working either. Are you using a crossfire bridge?

Update!

Just started up Gta V and got Blue screen when it launched!

You should REALLY check out what exact pau you have. That seems to be the only possible explanatiin right now. Also install the latest drivers again

Just thought about something. What was the error code for the blue screen?

That might help us find the problem
