I am hoping you might know what's wrong with this ckolivas. I can use cgminer to mine literally any scrypt based coin, LTC, NVC, FTC, MNC, all with no problem what so ever. For some reason I just can't figure out I can't mine any sha256 coin at all, BTC, TRC, PPC, Whenever i start cgminer a windows pops up and says cgminer.exe has stopped working.
Here is a screenshot of the error from event viewer:
I am using Windows 7 Ultimate x64
HD6950 & 6970 not crossfired
And cgminer 2.11.4
I really hope someone can help because this problem even exists after a complete wipe and reinstall of windows. Thanks in advance!

How to auto-fan and auto-gpu interract? I'd rather run up the fan than drop the clock speed so I have been using only auto-fan but I'm wondering if that's the best way or not.
--auto-fan and --auto-gpu are the commands that tell CGMiner to control you clocks and temps to maintain your target temp. After these command you can then set your desired thresholds that CGMiner then attempts to maintain. Rarely does CGMiner need to drop the clocks. My target temp for one card is 75c and the other is 60c and they never have had the engine clock dropped.
Read the top post of this thread paying close attention to the executive summary examples. I hear, unsubstantiated rumors that there is a readme file, or several, that are actually included with the software. I have been too lazy to verify this for you but it may be worthwhile to look.
Good Luck,
Sam

Well for starters, that command line doesn't even make sense../cgminer -o stratum.ozco.in:80 -u user -p pass -I 8 -d 0 -o stratum.ozco.in:80 -u user -p pass -I 8 -d 1 --gpu-engine 820,820 --gpu-memclock 1000,1000 --temp-target 80,80 --temp-overheat 90,90

At least look at the examples in the README.

Dear ckolivas & kano!
I have an unusual request: I use cgminer to mine testcoins. The problem I'm having is that your software is too good and too fast even on a low-end laptop and causes an increase of difficulty. Competing with myself in mining doesn't make any sense.
Thus far I've used "--shares" switch to periodically mine a handfull of blocks, but the problem with this solution is that it causes thermal cycling and cycling of the fans on and off.
I was wondering if you could suggest a way to quickly detune the CGminer to a slower speed: I know how many miners I run and I culd just make sure that they in total don't go above 7Mhash/s (or the equivalent for scrypt).
If this is currently impossible to do, please let me know where to inserts the appropriate waits/sleeps in your code. I could then rebuild my own version.
Thank you for any suggestions you may have.

it seems that CGminer is splitting the load between my two cards so running each one at half speed. When i run one GPU at a time with the -d command i can get my left video card to run full speed. But when i try to run them together the feedback states the mhash but when ending a session i see it was just split between the two cards.. When i try -d 0 and or -d 1 only my left card seems to want to work, and crossfire is not enabled.
This is on an Alienware M17xR2 Laptop with two 5800 Junipers, they should be running at about 185 mhash each

Doesnt that model have dual ATI Mobility Radeon HD 4870 in it?
If so then the speeds are nearly dead on according to this https://en.bitcoin.it/wiki/Mining_hardware_comparison

I'm having a problem on a clean windows 7 install, mining using 2 Radeon cards.
Whenever I quit CGMiner the system reboots.

My settings: -o http://btcguild.com:8332 -u -p --gpu-memclock 1000-1300 -I 9 --gpu-engine 1100-1200 --temp-overheat 85 --temp-target 80
I think you need --auto-gpu before your engine speeds so that it will adjust them.
Also I've never seen a range for memclock. I would set it to the lower clock speed. At least that is the way I interpret this statement
--gpu-memclock
Edit: I would throw --auto-fan in there too

Hi,
Sorry if this question has been answered before but cgminer 2.11.4 is not working with slush pool stratum url ipv6.stratum.bitcoin.cz:3333. It gives me this error:

I have a question (BTW, thanks for keeping cgminer updated, you are a hero :3)
Just got my new 7870, and the mining hardware charts on the wiki here: https://en.bitcoin.it/wiki/Mining_Hardware_Comparison
shows that hash rates can be from about 480-520, and I'm getting ~420 hash rate.
My settings: -o http://btcguild.com:8332 -u -p --gpu-memclock 1000-1300 -I 9 --gpu-engine 1100-1200 --temp-overheat 85 --temp-target 80
is there something I'm doing wrong here? I would really like to see another 60-100 hashes/s out of it, because my old card (that I didn't get for mining) hashed at that rate, lol. What settings should I change? How could I improve here? It is a dedicated server, so I literally NEVER use the GPU for anything BUT mining. Help would be appreciated, no hurry though, this is not an emergency as it is working
