CGMiner Ubuntu 12.10 x64 - mining starts for 15 seconds and stops

[Acrossfy]

Hi guys, please help me. All day I suffer with CGMiner =(
I have a very strange situation. I have two HD 7950. Proprietary driver and APP SDK and ADL SDK installed. I used this tutorial for make CGMiner.
When I run it, I get the following log:

Code:

I think you have to specify configuration for your card, take a look here https://en.bitcoin.it/wiki/Mining_hardware_comparison on the right you have specific configs that people use.

for example:

Code:

./cgminer (connection parameters) --gpu-engine 1130 --gpu-memclock 1900 --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256

Anyway, I recommend following steps from this tutorial: https://docs.google.com/document/d/1Gw7YPYgMgNNU42skibULbJJUx_suP_CpjSEdSi8_z9U/preview?sle=true It worked for me very well.

for example:

Code:

./cgminer (connection parameters) --gpu-engine 1130 --gpu-memclock 1900 --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256

I get:

Code:

cgminer: --thread-concurrency: unrecognized option 
cgminer: --shaders: unrecognized option

I run CGMiner w/o this options - for 30 second he worked(but on very low speed for my cards) and accepted 4 shares, and then speed falls to 0 and no more shares accepted..

P.S. Sorry for my bad English.

Antekh, with your tutorial i have the same problem.. mining starts for 10 seconds and stops...

Is this running ./cgminer without any arguments? Clear your .conf file (back it up first) and see what settings it autoconfigures. Double check that you have OpenCL installed properly as well.

Have you tried finding a cgminer.conf from a similar miner? There are hundreds of people Using Ubuntu + cgminer and I'm sure many of them are using 7950's. Just edit the .conf file to connect to your workers and give that a shot. If I used 7950's I'd help you out, but I'm running 5770's and 6870's.

Try starting with Intensity 8 or 9, otherwise set it to dedicated. I also suggest keeping your Memclock to 300MHz - 325MHz, as most guides will tell you.

Yes.

Installed OK.

Can't find..

Well a number of people have posted their scripts, look at the Hardware Comparison Charts to see what flags people ran via certain cards and software.

If anything, just delete the current cgminer.conf you have and then restart. And check that you have the latest proprietary drivers installed in Ubuntu. They have been better about getting AMD Radeon updates.

I tried it all. I used many configuration flags, but cgminer always stops. On Windows all work fine. On ubuntu i tried use the same configuration, but it still stops.

On ubuntu i installed DiabloMiner and it works fine, but only with one GPU..

2Moderator, can you please move my thread to "Mining" forum?

I've been seeing a number of people having problems with multiple 7950's. Try BFGminer or poclbm.

If anything try to recompile your cgminer and see if there are any minor errors that it throws out during.
