Title: crossfire and opencl?
Post by: bitcoin2 on November 09, 2010, 01:10:13 PM
Is it really impossible to work with opencl and crosfire together? Or is there a way ? Maybe there are windows or linux driver which make this possible. Or is this from a hardware impossible ?

If you are using m0mchil's OpenCL miner, you should disable crossfire.  You can run an instance of the miner for every GPU, so it is better to keep the gpus independent for best performance.

I have to use crossfire because I've got only one pci-e slot and would like buy a second ati-card for my computer to generate bitcoins. Any idea?

New motherboard? Where were you planning on connecting the second ati-card to start with?

Ok, my mistake. I thought that I could take crossfire as replacement for pci-e . it's a pity, no matter what - thanks
