OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[-ck]

If the driver is broken for mining, what do you expect cgminer to do about it?

no idea, its why I asked. Despite what my search said, I couldnt be the first one with the problem. I was genuinely hoping for a workaround or fix I missed.

The readmes go to great pains to say many times over that drivers and sdk are everything. I really wish people would pay attention to documentation.

Yeah there was a time when we could ONLY use 1 11.x driver.

Is it possible to use cgminer with HTTP proxy that have username and password autentication?

[bitpop]

proxifier?

Hei!!

I am having strange problem. I use CGminer 2.11.3 and on my 5970 I do not have a display after starting to hash. On the pool site I have a output for khash / s but I cannot see and change anything on the fly in CGminer.

Has someone an idea, what could be wrong?


Tnx in advance ...

Hy,

i have a Sapphire 7970 and try to mine LTC but i come in the best case to 400 to 500 kh/s has anyone an idea what i am doing wrong?

First i was on Sabayon 11 Linux with the amd beta driver 13.3 and sdk2.8 somehow i managed to change the driver to 13.4 and also tried sdk 2.7 no change.
Once i started to try other drivers like 12.10 my system crashed totally, right now i switched to xubuntu 12.04,  with sdk 2.6 but still with very low kh/s

when i try to change the engine clock and memory clock it has more or less no effect at all, kh/s does not really increase or decrease, the only effect is that at some point th gpu crashes and thats it.

with these options i start, which do bring the best result so far
--scrypt --auto-fan --temp-target 70 --intensity 13 --worksize 256 --thread-concurrency 22272 -g 2
Another question i have is, when i change the sdk and or driver, do i need to recompile cgminer or can i use the same binary?

thanks a bunch for any help.
cheers

Having big problems with cgminer 3.1.0 on windows 7 64 bit.

Using HIS HD 7970 x2 with catalyst driver 13.1

Direct 3D 9.14.10.0945
OpenGL 6.14.10.12002

I tried to setup cgminer 3.1.0 with the simpliest settings

cgminer.exe -o http://pool:port -u username -p password -scrypt


Cgminer directly crashes with the windows screen, that the programm is not working any more.

I have absolutely no idea what i can do :/

The HIS control center is installed too, should i deinstall?

I recently changed from nvidia to Ati card.

cgminer.exe -o http://pool:port -u username -p password -scrypt

Try --scrypt instead of -scrypt

I AM AN IDIOT! i think i can figure it out an post the result here.

just what is "intensity"?

Did you see this?

--intensity|-I <arg> Intensity of GPU scanning (d or -10 -> 10, default: d to maintain desktop interactivity)

and what does that mean? how does it affect miner output?

GPU-README (yeah another of the files people don't read)

INTENSITY INFORMATION:

Intensity correlates with the size of work being submitted at any one time to
a GPU. The higher the number the larger the size of work. Generally speaking
finding an optimal value rather than the highest value is the correct approach
as hash rate rises up to a point with higher intensities but above that, the
device may be very slow to return responses, or produce errors.

NOTE: Running BTC intensities above 9 with current hardware is likely to only
diminish return performance even if the hash rate might appear better. A good
starting baseline intensity to try on dedicated miners is 9. 11 is the upper
limit for intensity while BTC mining, if the GPU_USE_SYNC_OBJECTS variable
is set (see FAQ). The upper limit for sha256 mining is 14 and 20 for scrypt.

well, the intensity was set a -1 on the little machine that i am playing with. moving it to 5 raised the hash rate from 6Mhash to 10Mhash. moving it to 6 looked like it  caused the rate to drop a little, so 5 it is.

ok something was messed up with the driver installation.

Iam getting "only" 550 khs right now. I need now to find out how to implement a config file into all this and which settings for the card to put in

What hardware are you using for mining?

What hardware are you using for mining?

I'm using an Asus C60M1-I AMD C-60/ AMD FCH A50M/ DDR3/ SATA3/ A&V&GbE/ Mini ITX Motherboard & CPU Combo

The goals for this little miner were low cost an low power. as it sits it cost $180 dollars and is using about 40 watts. i'm going to be adding a sapphire 6570 video card tomorrow. that will bring the cost up to about $240.

Are you CPU or GPU mining  currently?  Not that it matters at this point I guess.  Since you'll be mining 80 to 100Mhs tomorrow.

10Mhash/s? how do you get the Mhash ? ty

GPU mining, but this board doesn't have a traditional Video card. I think it is attached to the CPU.

Did i mislabel? isn't Mhs, Mega Hashes? I've only been into this for about 2 weeks so it would be easy for me to mispeak.

Hi!

I have a smaller issue I have tested with  2.11, 2.11.2, 3.0 and 3.1 to date. I mine Scrypt coins, namely feathercoin and litecoin.

I have noticed that seemingly random, Cgminer crashes after Stratum disconnect. Usually, the server looses connection and cgminer will restart work after Stratum at pool 0 requests work restart.

Sometimes, after the disconnect, Cgminer crashes completely.


I use a Gigabyte 7970, Windows 8 professional, Ati driver version 8.982-120727a-144338C-Rage 6.

I use the following commands : --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256

Hi guys. Quick question : i'm trying to solo mine CHNcoin and when I run my freshly created solomine.bat, I get error -61. WHat does it mean and how do I er...." decrease TC or increase LG" I don't know what those two settings even mean.

Is it because overclocking software was started at boot or some other process is interfering with CG miner ?

thanks in advance for replying.

TC = Thread Concurrency
LG = Lookup Gap
