I hope someone can help me with a problem I've been having with guiminer on a 890fxa-gd70.
I can run 3 6870s no problem. But when I install a 4th 6870, guiminer crashes when I start it with this error:
...
I'm running 11.5 ati drivers with 2.4 sdk. I ran the ati driver install with all the cards plugged into monitors. All four card show up in windows including gpu-z. GPU-z shows that OpenCL is available on all 4 cards.
1. Which version of Windows do you use? You may have problems with "Program Files" folder under 64bit Windows. Solution: move your guiminer to another folder or use 32bit Windows.
2. Connective two cards with two(!) CrossfireX cables and enable CrossfireX in Catalyst Control Center (Perfomance->AMD Crossfirex configuration)
3. Start GUIminer
If you have any questions - PM me.
