Maybe not exactly a cgminer question...

I have to identical cards. How can i examine which one is gpu0 and which one is gpu1??

Hi, I'm pretty new to cgminer, have been using it to mine LTC, connecting to pools, and it worked great. Now I've switched to p2pool and there's a problem with (some of) my rigs: when p2pool isn't running (like when I reboot the machine that runs p2pool) cgminer just quits! It just stops working (tried all 2.11.x versions in windows 7), the window disappears and cgminer never restarts when p2pool is back up. This has never happened with other pools, only with p2pool... is there some special option needed to make cgminer "try" to connect to my local p2pool until it's back online and not just quit?

Hi,

i have 4 zTex FPGA running with cgminer - on startup i get the following message:

HS FPGA configuration failed: DONE pin does not go high


The boards are calculating - but what does this message say?

From what I have read, it is my understanding that cgminer does not like user switching.

Theoretically yes, but only if the http proxy is very permissive, and none will by default. A socks proxy will definitely work though.

Any ideas? To update I changed TC to --shaders 1792 (from memory, whatever the 7950 shaders are) and it worked - but was only hashing at about 8 kh/s a card. I'm more than happy to try anything suggested. Cheers.

Ok. I've read the README again. I mean this respectfully because I know how frustrating it would be when seemingly someone is asking questions that are answered previously or in the README but as far as I can tell my specific problem isn't addressed. I've spent about 4-5 hours trying to get it to work, configuring with multiple APP SDK and Catalyst versions, read through the README and SCRYPT-README multiple times, but still can't seem to solve this issue.

Yes, I could still be missing something, and if I am I'll look like an idiot, but I'm just saying it's not like I haven't been trying before pestering the forums and asking for help. I'm also trying to be useful and provide diagnostic information (hence the output of ./cgminer -n), and if I like I can run it further in debug mode with -T and -D flags to help out. I've also tried to make sure I'm using the right export settings before I run the cgminer (GPU_MAX_ALLOC_PERCENT, etc).

I've made sure I've run "sudo aticonfig --adapter=all -f --initial", and also checked that it can detect my cards and temps with "sudo aticonfig --adapter=all -odgt" which is successful. I've tried following this guide here - https://docs.google.com/document/d/1Gw7YPYgMgNNU42skibULbJJUx_suP_CpjSEdSi8_z9U/preview?pli=1&sle=true with no success (errors I'm talking about now).

I've rebuilt cgminer lots of times, ensure the configuration file is ok, including the ADL SDK and enabling scrypt as per the README. I've tried mirroring settings in the hardware wiki (https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison) and I'm still getting poor hashrates.

I'm usuing Xubuntu 12.10, Catalyst 13.1, AMD ADL SDK 5.0, AMD APP SDK 2.8. I will provide the full debug of the mining when I get home (at work). I have 8GB of ram as I know LTC mining is RAM intensive.

I've tried multiple intensities (I know -I 13 is popular here), workrates, lookup gaps, GPU threads and shaders. I've gone through the 7970 tuning example.

Please, if you can give some actual advice to try I'd be really appreciative. Again I know it seems frustrating when someone comes in and possibly hasn't looked at the basics, but as you can see I've tried quite a few things and spent a lot of time on it. I'm not pretending I haven't missed something basic, I could definitely be at fault, but just point it out to me please instead of asking me to read the README again.

Hi Everyone

I have tried quite a few settings, but I cannot get cgminer to stop dropping the clock speed on one of the cores on my ATI 5970 dual GPU card.

Here is my startup string: (I know its scary but temps don't go over 80 degrees)

cgminer -o http://pool.com -u username -p password -I 9 --gpu-engine 930,930 --gpu-vddc 1.2 --gpu-memclock 300,300 --temp-hysteresis 10 --gpu-fan 85 --temp-target 100,100 --temp-cutoff 105,105

With these settings, cgminer seems to keep dropping the first core from 930 to 550 every few seconds for a second or two. From what I can tell, it is trying to maintain a temperature, but why when I have disabled all auto watch stuff from within the application?

Can anyone help or give suggestions? Thanks

Changing SDKs there is no need for a recompile, but you must delete any .bin files generated so they're regenerated. Note there is no clean way to uninstall though so be careful when removing the old one to make sure it really has gone. AMD seems to have taken its ideas for uninstall from windows where you just say it is uninstalled but leave half the files there.
