Hello guys,
I've tried today last cgminer(2.11.3win32), on my Win8x64/Radeon 5850 card/Catalyst 13.3 beta but it crash on start.

Code:

cgminer -o stratum+tcp://coinotron.com:3334 -u blabla -p blabla --scrypt --thread-concurrency 8000 -I 18 -g 1 -w 256

Can you help me?

On Ubuntu 12.10/Catalyst 2:9.000-0ubuntu3 works flawlessly.

It works now... solution is on bottom...

Hello,

since my roommate has a new notebook with a NVidia GT 670M i wanted to check if its useful to mine with it now. So i set up an account at pool.itzod.ru and used the standard commands they suggested.

I tried with -I 9 but it failed everytime. The driver crashed. But under 9 it works fine at least. But i wondered by its only 14MH/s. It should be 112MH/s judging from the tables. So i checked GPU-Z and found that only the desktop-GPU is working. Optimus isnt enabling the GTX. And this gpu works with 14MH/s. I then tried forcing the use of the GTX for the cgminer.exe. But it doesnt change. Its still using the desktop-gpu but with even less MH/s. Its 1-5 only.

What can i do to force the use of the gtx 670M? And is it maybe even possible to use both gpus at the same time?

I wonder why it crashed with -I 9 when its the standard. But maybe it will work with the normal GPU with such values.

Does one have disadvantages using stratum with gpu or isnt there a disadvantage?

Thanks!

Edit: I checked out the command -n  and got this result:

Intel HD Graphics 4000 is the normal GPU and GeForce GTX 670M is the fast GPU. Optimus should switch between it when speed is needed. It seems to not work.
So i tried the param -d 1 to use the second GPU but it told me there is no device.

Edit2: It works now. I used the param --gpu-platform 1 -d 0 and now the real gpu is mining... I will test if i can mine with the other too now. But at least it runs now...

Hi i have a problem. I have 2 hd7950 ans i want to mine ppcoin (bitparking) but it dont work. Someone can share me settings for 7950?

[jhd]

I setup it and i have only 600mhash for 2 7950 cards. Its very poor

[SebastianJu]

I have only 53MH/s for a 670M too. The Desktop 670 is with 112MH/s in the list. I tried everything but it remains there. Im not sure if it can be that its so much less only because its the notebook-gpu. But it wouldnt turn out to profit to mine with it anyway most probably.

[dresdenreader]

Was wondering if someone could help me troubleshoot my cgminer.

As I've stated in another post, for whatever reason I am unable to mine with any version of CG Miner past 2.10.3. I'm able to mine without any issue whatsoever using 2.10.3. But starting at 2.10.4 and onward, CG Miner just stops running shortly after it probes for an alive pool.

This is the command line I'm using: (same command line works perfectly with 2.10.3)

Code:

Lastly, I installed Dr Mingw debugger and this is the output text from cgminer when it crashes:

If you want I can try and provide more information if required, but this is what I'm currently experiencing.

Additionally, this is what I'm seeing when I run the -n command.

The first snipped is the output from 2.10.3.

I ran this with the newest debug version of cgminer.exe and got the exact same results (minus the newly added USB support of course.)

Most likely your driver version is the problem ...
But you haven't provided any useful information.
Could even just be a setting you've used ...

Hi Guys,

Does anyone know any flags that might assist in keeping GPU temps down with a small sacrifice to the hash rate? Its very hot where I live during the day and I noticed regardless if I run cgminer with low aggression and low thread concurrency the temp is the same as with higher settings.

Im running 2x 7950's with no flags at the moment just the profile in guiminer

Reduce --gpu-engine limits

Hello. Latest CGminer shows that my 7950 runs at about 650 k/h, but mining pools (i tried 4) show in stats (and pays so) that i make only about 150-200 k/h.
But if i use Reaper, pool stats shows real 600-650 k/h (and pays). So what it means? Technical problems, or CGminer stealing k/h for some backdoor pool?

Here, want to help on a problem with documentation? try this...

The problem is not the card as it was working before and is currently working under a different kernel.  As long as lspci can see the card I can use it... except on this one machine which is driving crazy.

Happy to try another OS though my experience with Ubuntu was that lspci didn't show multiple cards (same problem I'm having with Centos 6.4).  I know I have had cgminer operating under centos 6.3 with all gpu's operating on a multi card system and as I say I f'd up when I upgraded to 6.4.

Where is there some log file that can give more info?  ANY advice appreciated.

You can also reduce your temp target.  Read the executive summary in the first post for examples.  What temp are your GPU's running?  Mine are around 74C with a target of 75C.

Really?!?!

Don't be such a Drama Queen.

I'll take a look at this today after work.

Is there a reason that the AMD SDK APP I'm trying to install isn't properly taking hold? It appears to install and go through the entire install process and report as success but it looks like its still not the right now. Would you recommend a particular SDK?

[redmist]

For some reason when I open up cgminer, I get greeted with the error message:
ADL found less devices than opencl!
There is possibly more than one display attached to a GPU.

I'm pretty confused with this because I haven't done anything that would cause this. The only thing that I've done today is add my second GPU into my rig. I've got 2 5850's running at the moment.
Anyone know why this is happening, and what I can do to stop it?

Secondly, for some reason there are no temps being shown in cgminer any more. Anyone know why this is, and how I can get them back? Kind of makes it difficult to monitor

Out of curiosity, what is your monitor setup?
