I'm running Xubuntu (linux) and as mentioned before I installed the drivers via the public repos. If I'm only mining on one GPU with two OpenCL instances then wouldn't that be a configuration issue in cgminer and not my driver?
Fine, don't believe the person who wrote the application  Ya got me and you're most likely right. Eating my hat now....... (I was doubtful because I was installing the driver per the instructions of every tutorial I've seen so far.) I ended up trying Windows out since that seems to be what most folks on this forum are using (by my guess) and now I have both cards achieving their expected hashrates. My new problem is that with --auto-fan and --auto-gpu set along with the default target temps my cards now heat up until they hit my cutoff temp of 90C, disable, cool down, then re-enable, but DON'T take on any jobs after that and just sit at an idle 0 hashrate. Any thoughts? |

I'll see if I can find another linux driver but honestly I don't think that's the issue. I'll also try with Windows 7 just to make sure one of my cards isn't defective or something.
Any other thoughts folks? I was under the impression a lot more people were using linux on their miners but it seems like most of the folks who replied to this thread are using windows.

My configs are from scratch and the system is sitting in an open hallway with plenty of airflow. One of the cards in the case is towards the top but it has enough space to suck in air. I think this is some weird config issue or maybe a bug in cgminer. Here's my latest running config: {

Also check this out, the system has been sitting for a few minutes like this. GPU 0 is overheating and has the fan running yet it is in "REST" mode while GPU 1 is a nice idle 59C yet it's doing all the work. Make sense of that? cgminer version 2.11.4 - Started: [2013-04-18 23:48:12]

I installed the drivers via the reps: sudo apt-get install fglrx-updates fglrx-amdcccle-updates fglrx-updates-dev The system is headless at the moment so there aren't any monitors connected. I've read everywhere that the crossfire bridge only causes problems. Mods, can you move this topic to the appropriate section? Thanks |

I'm also starting to wonder if only one of the cards is actually being used since only one of them is getting hot. Here's an updated console output a few minutes later: cgminer version 2.11.4 - Started: [2013-04-18 19:00:02]

try adjusting the intensity to 9,9 (under GPU menu)
I have a similar setup with two 7970s in one rig (without crossfire bridge connecting them). Running Win7 x64 and BFGMiner with just the -I 9 flag, and am getting about 650 Mh/s per card with core clocks set to 1075 MHz.
Set intensity to 9 with the same results. Temps are lower because I've left it off: cgminer version 2.11.4 - Started: [2013-04-18 19:00:02]

***MODS, could you move this to mining support? Thanks*** I just got my system put together and I'm having troubles getting CGminer configured correctly. I tried starting out with a few example configs and eventually went through the readme and built my own from scratch but am still running into similar issues. My problem: I'm getting about half the performance I should be with both cards enabled. If I disable a GPU or give one a higher intensity than the other then the individual card starts outputting the hashrate it should be. I'm also seeing one of them hit 95C (OMFG!) even with autogpu and my target temps set ~70C. Any and all help would be greatly appreciated!!!!
