Like this? :-)



Well, I looked at doing it for my Radeon, but it turns out was already installed by default.
That's why I indicated that the recommended "GPU Caps Viewer" indicates that OpenCL is available, with one device. (I'm no graphics hacker, but this looks like an extremely comprehensive utility.) (I'd post a screenshot if it was allowed.)


Hmm, yes, but the error pops up before I have the chance to select anything.
Then it cuits.


I will give that a try; thanks.

You should post what hardware you are trying to do mining on when asking a question like this. I'll assume ATI GPU since that's about all that makes sense these days.

Those python errors mean the miner couldn't connect to OpenCL, which is the language for programming the graphics processor. I've had the OpenCL crash and needed to restart the computer to get it working again. If it's never worked though, download and install the OpenCL driver (http://sites.amd.com/us/game/downloads/Pages/radeon_win7-32.aspx#2) and/or ATI Stream SDK (http://support.amd.com/us/gpudownload/Pages/sdkdwnld.aspx) by itself (2.1 for pobclm or 2.4 for phatk). In guiminer, there's a drop-down where you pick your device, make sure you've picked your video card and not the CPU.

If guiminer won't go, try command line phoenix miner to be sure OpenCL works (once you see command line working, you'll want to run that full time since it gets more hashes BTW). Just download and unzip phoenix miner (http://forum.bitcoin.org/index.php?topic=6458.msg94376#msg94376) to it's own directory. Here's a start.bat file I made to start phoenix command line with one click, optimized for 58xx gpus:

phoenix.exe -v -u http://user:[email protected]:8080/ -k phatk VECTORS AGGRESSION=12 BFI_INT WORKSIZE=256 PLATFORM=0 DEVICE=0

or if you actually need to use your computer for something other than mining:

phoenix.exe -v -u http://user:[email protected]:8080/ -k phatk VECTORS FASTLOOP AGGRESSION=4 BFI_INT WORKSIZE=256 PLATFORM=0 DEVICE=0


(that's all one line, save it as a text file in the phoenix directory, then rename the .txt extension to .bat)

Change the user, password, address, and port above to your pool's settings and your worker username and password.

Here the function call of interest from guiminer.py.  It can't find your OpenCL device that you have selected in the drop down (this Assertion is that the number of devices found after it searches for the selected device in your device list is "not None").  Since it is none, then the AssertionError is thrown.  I would say that you need to double check your OpenCL SDK installation.

If you already had the GUI set up and then added another card, you might have to delete some of your config files in the app folder and reinstall. Just make sure you back up your wallet before you go doing anything crazy.

I setup it on 3 of my computers no problems 1 had a q6600 and 8800gt 1 had a e5300 with a 8800gt and my pc with a i7 and a 5970+5870 all 3 configs worked without any problems each had windows 7 64 bit.

I think GUI miner only works with OpenCuda cards - i.e. ati/amd cards. You might want to look into a ubuntu setup that supports nvidia.

Same here. Windows 7 SP1...
NVidia 9800GT (no smoker, I know)
The "GPU Caps Viewer" shows OpenGL, CUDA, and OpenCL" as being available.

I can't do anything! Any ideas?

yes, of course i've done that. i tried many different AMD drivers and several different versions of GUIminer, reboot each time and get that error every time. i'm thinking some kind of file in my system got corrupted.

Have you done all of the basics? (uninstall - reinstall, reboot, update drivers)

hi, since i can't post in Kiv's GUIminer thread, i'm making a new one in the newbie section. the newest miner won't open on my computer. every time i open, there's a error dialog that pops up saying: "See the logfile C:Users\Username\guiminer\guiminer.exe.log for details", and then the programs just crashes. then once i open that log file to see what's wrong, this is the log:


what does AssertationError mean? and how can i fix this?
