Thank you! Your code works fine for me now. I briefly tried tuning the parameters, but couldn't get it to run faster than ~4150 c/s. So I cheated: XAUTHORITY=~user/.Xauthority DISPLAY=:0 aticonfig --od-enable --od-setclocks=1250,1375 This brought the speed to: Benchmarking: OpenBSD Blowfish OpenCL [BF_OPENCL]... DONE Raw: 5556 c/s real, 238933 c/s virtual which is about the same as the CPU - meaning we can double the speed by using both the CPU and the GPU at once (two instances of John). The card stays cool (71 C) since we're under-utilizing the GPU anyway. ...Oh, I got "ASIC hang" after: guesses: 345 time: 0:00:03:28 0.00% c/s: 5449 trying: 123456 - random Whatever. I'll bring it back to stock clocks (925 MHz core). BTW, 1300 MHz resulted in John's self-test failure, and 1250 MHz worked for 3.5 minutes as you can see. I don't know if the "ASIC hang" was related to the overclock or not. Alexander
