Try using the '-t' flag to change the thread count (maybe one less than your number of cores as a starting point), so for a 4 core system you might put '-t 3' into your bat file.

My i7 950 CPU is at 100% (all 8 cores (4+4)) and speed is 3,5-4,5 kH/s per core (avarage total=40 kH/s)

Average is 32 kH/s, not 40.. xD

Btw, why on https://coinotron.com/coinotron/AccountServlet?action=myaccount it says that my Hashrate is 28 kH/s for my GPU? :/

Could the issue be related to cgminer not supporting cpu mining anymore (I believe guiminer is a front end for cgminer)? I think it would be easiest to run it the same way tmu does, using pooler to mine with the cpu instead.

Wow, it seams to works now, TNX! But I think I have a small problem.

I've found http://sourceforge.net/projects/cpuminer/files/ on Google and downloaded http://sourceforge.net/projects/cpuminer/files/pooler-cpuminer-2.3.2-win64.zip/download

Then I've created START.bat (c:\Users\Ivan\Downloads\pooler-cpuminer-2.3.2-win64\START.bat) with this content:

minerd -o stratum+tcp://coinotron.com:3334 -O MyWorker2:MyPass2

I've start BAT file and IT WORKS Cheesy

. My i7 950 CPU is at 100% (all 8 cores (4+4)) and speed is 3,5-4,5 kH/s per core (avarage total=40 kH/s)

But the problem is that cgminer.exe (GPU mining) starts to throttle/have disconnections Cheesy

. And current GPU speed is 100 kH/s (it was 130-150-170 kH/s).

I guess minerd.exe suffocate cgminer.exe? Altough, I can normally work in Windows even CPU is always on 100%.

Can I somehow little limit minerd.exe with some parameters in BAT file? Or change priority/affinity in Windows Task Manager?

No, you've understand it wrong. GUIMINER for GPU uses cgminer.exe, but for CPU setup it runs "guiminer-scrypt_win32_binaries_v0.04\reaper-bb\reaper.exe". I've post settings for cgminer just to show how this stupid GUIMINER made wrong settings for GPU also (but I've fixed cgminer for GPU with manual changes, with help at IRC (chat)).

OK, I will try this "pooler-cpuminer" for CPU. I am new in all this, this is my first day, so I didn't know that there are more applications

What happens when you try to run into without the 'sharethreads' and 'lookup_gap' parameters? Based on the output you are encountering, it would appear those lines are what the program is complaining about. Is it possible those parameters need to be equal to the value? (ie. sharethreads=32)?

Yea, I also guess that this is the problem (last 2 lines).

When I delete those 2 lines, reaper.exe starts and stops without any error. It's same when I left those 2 lines, but without "2" and "32".

I didn't understand that at the end ("equal to the value")? To put "=" sign before 32? I've try that and its the same.

i started mining yesterday for the first time using the following guide

http://cryptocur.com/litecoin/litecoin-mining/

Tnx, I will look if I can find something useful there

I couldn't either make guiminer to work with my i7-2670QM,
I have no recollection about the error messages.

I use pooler-cpuminer and cuda miner for 555M, win7.
Hash speed is not too good combined Hash is around 37-55Mhas/s.

I have .bat file to start mining:

minerd -o stratum+tcp://YOURPOOL.com:3333 -O WORKERNAME:PASSWORD

Slow but it works.

Teemu

Yea, "guiminer" also created bad BAT file for my GPU ATI 4890 ("guiminer-scrypt_win32_binaries_v0.04\cgminer\mine-Default.bat") so I had to edit it manually (someone helped me at IRC).

This was created by GUIMINER:

"c:\Users\Ivan\Downloads\guiminer-scrypt_win32_binaries_v0.04\cgminer\cgminer.exe" --scrypt -u MyWorker1 -p MyPassword1 -o stratum+tcp://coinotron.com:3334 --gpu-platform 0 -d 0 -w 256 -v 1 -I -g 1 -l 1 --thread-concurrency

and with that I was always geting error “cgminer.exe:–thread-concurrency requires an argument”

This was manually edited and it working OK (I'm getting 160 kH/s):

"c:\Users\Ivan\Downloads\guiminer-scrypt_win32_binaries_v0.04\cgminer\cgminer.exe" --scrypt -u MyWorker1 -p MyPassword1 -o stratum+tcp://coinotron.com:3334 -I 12 -g 1 -w 128

(I also need to manually start it with mine-Default.bat - If I run it from guiminer, guimner again put his bad parameters).

hi, I've started mining LTC's with GPU at coinotron.com, but I would like to mine with my CPU (i7 950).

when I run it, i've got error:
Warning: unknown property "32" in configuration file.
Warning: unknown property "2" in configuration file.

This is the content of configuration files. Does anyone know what is wrong?
