Title: [SOLVED] Can't get cgminer working
Post by: Varog on December 16, 2014, 03:22:09 AM
Hello All,
First of all, forgive my English, I'm not a native speaker. Please, also forgive if my request is stupid but I can't cope with my trouble and need at least a clue. My "CGMINER" won't mine. In fact, I have got not a single cgminer instance but about ten, and some of them are Sgminer, and till one moment they all worked. I haven't changed my hardware in the meantime. The major thing I've done was to reinstall Windows several times willing to downgrade from 8 back to 7 (just for my comfort). From my memories, I also played around some BIOS hardware settings but eventually I loaded the defaults which for sure worked before.

The basic output of the faulty cgminer is "clDevicesNum returned error, no GPUs usable  All devices disabled, cannot mine!" - I have googled and read everything around this error but nothing helpful.

The detailed output with -n argument derives the following:

[06:18:57] Failed to ADL_Overdrive5_FanSpeed_Get for default value

I also ran CompuBench CL and OCCT and everything went smooth. GPU Caps Viewer gave me a single error:

Otherwise it works OK..

And, of course, I've tried different versions of Catalyst under both Windows 7 and 8, and the result is the same at all my tries. Any help will be very appreciated.


UPD: Assuming that my efforts can help somebody else. As expected, the catch was very simple and difficult to notice.

I only changed one argument in sgminer.conf file "gpu-platform" : "1" -> "gpu-platform" : "0"

Apparently, before my reinstallations the iGPU was read as "0" and PCIe as "1". Now it's vice versa, for some reason.

You didn't put the most important info which is your GPU model. If you are using nvidia GPU then cgminer will not work.

ASUS HD7990 = 2xATI 7970
In the code field above you can see any details about the HW and drivers
Thank you.

check drivers and try lower version too.  8)
i find sometime you use lower version and better result.

that's neat, what do you use to watch the code ?
