Howdy,
After successfully initializing and listing the 4 GPUs on my system, I take a look to see what candidates are available:
root@localhost:~# aticonfig --lscc
Master Adapter: 0. 01:00.0 AMD Radeon HD 7900 Series
Candidates: 3. 06:00.0 AMD Radeon HD 7900 Series
Master Adapter: 1. 02:00.0 AMD Radeon HD 7900 Series
Candidates: 3. 06:00.0 AMD Radeon HD 7900 Series
Master Adapter: 2. 05:00.0 AMD Radeon HD 7900 Series
Candidates: 3. 06:00.0 AMD Radeon HD 7900 Series
Master Adapter: 3. 06:00.0 AMD Radeon HD 7900 Series
Candidates: 3. 06:00.0 AMD Radeon HD 7900 Series
I am confused by this output as it seems that I cannot setup 4-way crossfire.
This was attempting using the proprietary driver (per thread) on both Debian/Squeeze and on Debian/Wheezy, using Xfce4 environment with same result for both.
Does Catalyst 12.3 allow crossfire on HD7970 GPUs? If so, does it allow 4-way? Am grateful for feedback. I kept my listing short, will gladly provide other diagnostic info.
System:
GA-990FXA-UD7, AMD 8120, 8GB RAM, 4xASUS HD7970
