It is good practice to manually uninstall the opencl package when upgrading to the next driver version. could you explain how to uninstall the opencl package? Is this done after uninstalling CCC, then reboot, then installing CCC again?

Nano, will try your suggestion if it does it again. Dont think it will help though. When I saw the stuck wu, I aborted it, boinc went to the next GPU wu and did the same issue again. I found more stuck today and it's because the driver was crashing. The driver would restart but the task didn't unless I suspended and restarted. Tried newest beta driver(12.9) problem was worse. 12.8 was the driver crashing so I rolled back to 12.6. So far so good. I downloaded 12.4 but after the install, it was actually 11.2. Even the file showed 12.4. Weird. Went ahead and downloaded 12.8 and installed. Waiting on boinc to download some GPU wu's to see if its fixed. Dam CCC was hell to uninstall. Took 2 uninstalls and reboots to finally get rid of all of it. 1st time I had this issue. Wish I would have left 12.4 I had in there as never had issues with betas before. Have a feeling 12.8 is the culprit. Nano, are you using CCC? If so, are your settings in overdrive maxed out? Still having driver crash issues with 12.6. Too late to play with it any more. All my other machines use 12.8 without issue. It's only the 7970 that's crashing. I never install CCC. Not that it's bad, I just try to install the minimum I need to run the tasks.

Woke up this morning to find 54 GPU wu's and stuck on one of them. Waited until it would hit 10 minutes, then aborted it. Boinc went to the next one, screen freeze, then a message of driver recovery pops up. Then it would stick on that one but not crunch (verified by watching CCC). Aborted all of them and unselected from HCC project until I can find out what happened. I thought it was posted (couldn't find it) that there was a limit per machine for GPU wu's. My other cruncher with a 5670 is still crunching fine though received about the same number of them too. So far, the GPU is functioning fine without crunching with it. Even had the fan kicked up to 50% to keep it cool so I know it didn't overheat. At a loss right now as to why but hope to figure out the issue. Anyone else with AMD cards having issues like this? Hi Bearcat! I recognize this behavior. This can happen when the catalyst driver has crashed and been restarted automatically and in this case you don't need to restart Windows, you just have to shut down BOINC and restart it. Most likely you stress your GPU too much, try to down clock it or if you running multiple wu's by using an app_info file try ro run less wu simultaneously or just stop using the app_info file. Hope this helps. [Edit 1 times, last edit by Simplex0 at Oct 14, 2012 10:50:04 AM] |

Also see boinc go from one to another smoothly so maybe it needed a reinstall. Nano, try dropping down to 2 at a time to see if that fixes it. Think your stressing the card out.

Is this done after uninstalling CCC, then reboot, then installing CCC again? During the uninstallation setup you must manually uninstall the AMD APP SDK. This is the package that provides OpenCL to your graphics card driver. When you experience problems running opencl programs that cause display crashes it is directly related to this package. Sometimes the automatic driver installation setup doesn't install this package correctly, or for some reason doesn't uninstall it. [Edit 1 times, last edit by mmstick at Oct 14, 2012 2:33:01 PM] |

When uninstalling, I see that AMD APP SDK is checked (I do a custom uninstall to insure all are selected) to uninstall. So do I find the folder to delete or run the uninstaller again?
----------------------------------------Since uninstalling, rebooting, installing yesterday, everything is working great. No continued crunching after reaching zero completion time, goes right to the next one when finished. One thing I have wondered is I was using 22 out of 24 threads to crunch. Am wondering if when it went back to the CPU there was some bottleneck going on. Have changed to 22 threads crunching to see if any difference, and so far no issues.

Sometimes you need to run the Microsoft Installer Clean Up utility and select AMD APP SDK and uninstall it there manually as the catalyst setup will sometimes not uninstall/install it even if it is checked.
