Title: Unable to detect second GPU in Ubuntu.... tried a dummy plug Post by: bobbobobbo on May 22, 2013, 08:22:10 PM Not sure whats going on.... 1 card works fine, yet the second I add another 7950 I get this readout from CGminer:
[2013-05-17 16:46:01] ADL found less devices than opencl! [2013-05-17 16:46:01] There is possibly more than one display attached to a GPU [2013-05-17 16:46:01] Use the gpu map feature to reliably map OpenCL to ADL [2013-05-17 16:46:01] WARNING: Number of OpenCL and ADL devices did not match! [2013-05-17 16:46:01] Hardware monitoring may NOT match up with devices! and can't get any temp/speed monitoring. I've tried this dummy plug guide here http://blog.zorinaq.com/?e=11 yet still have no luck.... frustrating. Any ideas? I have export display=:0, gpu_max_alloc_percent =100, and gpu_sync_objects =1 before my cgminer input.

Code: aticonfig --adapter=all --lsa Title: Re: Unable to detect second GPU in Ubuntu.... tried a dummy plug Post by: bobbobobbo on May 22, 2013, 10:08:23 PM What do you get with: Code: aticonfig --adapter=all --lsa I tried Quote sudo aticonfig --adapter=all --initial -f not sure the differences using initial and f but that did the trick, so basically what you posted. Unfortunately now... I get GPU 1 failure within 2 secs of connecting to a pool. Error -5: enqueueing kernel onto command queue then gpu failure and disabling Title: Re: Unable to detect second GPU in Ubuntu.... tried a dummy plug Post by: Ultraviolet on May 23, 2013, 05:29:05 AM I had to switch to Xubuntu 12.04 and 12.8 Catalyst drivers.
You could try just the 12.8 Catalyst drivers if you don't want to reinstall. |
