CGminer crashes on start, multiple graphic cards [Solved]

[daggeteo]

I got problems getting CGminer to work at all, it shuts down directly.
I've tried several different versions of cgminer 3.1.0 and 3.0.0
Different flags have also been tried with no success, program just shuts down directly all the time.
I tried running just one of the cards with the "-d 0" flag but it didnt work.

here is a version of what I have tried in my .bat file

cgminer  --verbose -o http://stratum.d7.lt:3333 -u [myworkername] -p [mypass] -d 0 -g 1 2>logfile.txt

The output to the logfile is

I had the latest drivers (13.4) for the gpus 5850s from the start, so i uninstalled them and wiped the system clean(with AMDs uninstall utility), reinstalled a older version (13.1, I think, can't remember if it was 12. that seemed to work for others but no luck for me.

Now after failing in basicly every turn i take i went back to the latest drivers so atleast can mine at slow pace with Bitminter-client which works now.

However i'd really like to get CGminer to work so i can start tweak the settings and get more out of these cards.

I appreciate any advice, thank you!


I had nvidia cards prior but all drivers and programs associated with nvidia has been uninstalled.

TLDR

• Tried different drivers
• Tried different versions of CGminer
• Can mine with the Bitminter client, it works
• Tried different versions of CGminer
• Rig consists of two HD5850s
• Powersupply is a Corsair AX850
• Googling has not yielded any results and my troubleshooting is at a standstill, need your help!

Edit: The solution was to uninstall current drivers. Delete certains files (read msg #3 for which ones) and then reinstall 12.8.

The issue may be the 2 after the -g parameter.  I think CGminer will parse this as wanting to use 1 GPU thread and then will see the 2 and see that as an extra argument.

Whenever I make changes to my CGMiner configs and I get immediate exist, I open a DOS windows to that folder and run the batch file.  It usually complains of some incorrectly parameter.

Hi,

That part is just for writing the logfile but CGminer will not work even if I remove that.  But I'll give the CMD idea a shoot later on and see what'll come out of it.

I received some help through the chat at one of the pools.

Basically what he/she said was that I'd have to se and older "SDK runtime" (12.8 for example). I'd have to uninstall the current SDK Runtime and then manually remove the files "amdocl.dll" and "opencl.dll" from  C:\Windows\system32 and C:\windows\Syswow64.

After that install SDK Runtime from Catalyst 12.8. Apparently uninstalling catalyst even with the tool will not remove these files and therefor they have to manually deleted.

At the time I'm writting this I haven't had the chance to try these things out. I'll update when I know more.


Disclaimer: If someone reads this and tries to remove the files, please remember that you do so at your own risk

I have used Driver Sweeper with some success to help with this file deletion as well, if this helps...  Uninstall the driver, boot into safe-mode, run Driver Sweeper, select AMD-Display, Analyze, Clean, reboot and then reinstall the new driver version you want.

Great tip! I'll try that tomorrow!
