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

As far as I'm aware I should be able to go up to ~20000 TC, what's up?
Any help greatly appreciated.
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. README FAQs 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. 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. Ok, so going off that you're saying 2.8 is crap, roll back to 2.7 (given I need 2.6+ for 7xxx cards) and recompile cgminer? As I mentioned with the Xubuntu guide I did try 2.7 before, but I was having issues then with the 13.1 drivers. I'll try it again since I've got the 13.1 working now. Thanks for at least pointing me in the right direction.

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.

Ok awesome, thank you for your help. I'll report back with how it goes.

Here's an odd one I'm running into today after re-burning my USB stick's linux image from a clean copy, pulling in the latest git, compiling and firing up cgminer...
cgminer's interface ignores all normal menu keystrokes (p, g, and so on), UNLESS I neglect to specify a pool in the config file, in which case it works normally because it had to accept keyboard input to allow me to set the pool credentials. I can use ctl-c to kill it and get back to a prompt, no problem. I just can't adjust settings while cgminer is running.
This is latest git pull as of "Thu Apr 11 13:31:17 2013 +1000".

Hi Everyone

From what you describe later on it's probably the driver doing it, not cgminer. If you see that, you better start clocking your core down: if the driver is protecting the card by clocking its core down automatically it means you are slowly damaging the hardware: you'll fry the VRM eventually.

Got my first Debian Linux (squeeze) based rig online and working, so I have a completely Microsoft-free system now. :) Materials I found helpful: - the starting post of this thread - this post: https://bitcointalk.org/index.php?topic=3359.msg47174#msg47174The hardest part for me personally, as it was mostly undocumented, was understanding that I need to start "cgminer" as a regular user (not root) and issue the commands from a local X session (not SSH). Before that, I was vainly trying to understand why the following error occurred: Error -1: Getting Device IDs (num) clDevicesNum returned error, no GPUs usable All devices disabled, cannot mine! As soon as I changed to user instead of root, and local console instead of SSH, all the things which should have, started working.

Hi,
I switched from GUIminer to cgminer on my win7 based rig two days ago. I have two issues though that I can't seem to find the answers using the board search or google...
- The guiminer output does not show GPU temps and fanspeeds. I watch it via RDP. I noticed that I saw temps & fanspeeds once when initially configuring the box having a display connected to one of the cards. This is not a cgminer specific problem, as I have the same issue with other programs like GPUz. No clock, temp, fanspeed displayed.
- Tweaking GPU/mem clocks does not make any difference. Is this due to having CCC running in the background? Might that be related to my first problem as well?
thx Manfred

Nope. Unfortunately I didn't know about it yesterday, and besides, this particular mining rig will have to host other applications too, so perhaps a standard Debian is better for it too. Thanks for pointing it out, however -- on the next machine which is basically nothing but a PSU, mainboard and 5850 GPU (once I get a spare 5850), I'll definitely try this approach, a bootable USB stick sounds like a sensible way to reduce power consumption. :)

Running RDP to the mining rig kills the GPU and crash's CGMiner and requires a reboot of the whole mess. That's been my experience anyway.

Hello, I was wondering if anyone could help me with my problem posted here: https://bitcointalk.org/index.php?topic=174091.0Basically my second gpu is being detected, but I can't get temps or overclock with cgminer.

Server is being DDoSed so download links are broken again till it's over. Looks like DDoS is the new black.

I got a question API requests are persistent? So if I reopen cgminer it will use default config arguments? Or will it use the ones I used on via API (Anubis front end)?

I was going to paste a link to my site but don't want that DDoSed  So this should work better - 2.11.4 for Windows in 7zip format --> http://www.sendspace.com/file/s14bk2

Anyway you can add some of these files to a mirror? I'd love to get my hands on the latest linux .tar.bz2!

I meant it has all the info needed to install cgminer on USB or HDD with an older OS (Xubuntu 11.04) Looking through there would have answered your problem about SSH since it is in there also.
