No need for Xfire..it slows hash rate..

For 7 series cards use 2.5 AMD APP. It is faster.

MY 6870 on AMD APP 2.8 gets 230 Mhash | On 2.5 APP it gets a steady 305
MY 7970 on APP 2.8 gets 560 Mhash   | on 2.5 it humms along at 700 + Mhash

Your mileage may vary...lol

What is 2.5 AMD APP?

Okay, by disable do you mean disable in the software driver, or take the crossfire bridge physically off as well?

Dissable crossfire

I use 12.11beta, I've had nothing but problems with 13.x (I'm sure someone from Nvidia works in the AMD driver department!)

Just curious if crossfire is better for 2 radeon's for mining, or should I not even bother linking them together?

Is it better to enable or disable it, and should I use the beta drivers or not?

Thanks guys!
