no one can help you without seeing the settings you're using.

okay here some settings I'd tried:

cgminer.exe --scrypt -o "http://fc.ltcoin.net:6666" -u "username" -p "password" -I 13 -g 2 -w 256 -shaders 2048

cgminer.exe" --scrypt -u "username" -p "password" -o "http://fc.ltcoin.net:6666" --gpu-platform 0 -d 0 -w 256 -v 1 -I 20 -g 1 -l 1 -T --thread-concurrency 15508

cgminer.exe" --scrypt -u "username" -p "password" -o "http://fc.ltcoin.net:6666"

(cg miner with scrypt now crashes - tried 3.1.1 and 3.2.1 but same result)

minerd.exe --algo scrypt --scantime 99 --url http://fc.ltcoin.net:6666 --userpass username:password --threads 99 --retries -1 -P

Greetings!

I see that you are using the --gpu-platform argu do you have more than 1 gpu installed? are you pointing to the correct one?

cgminer.exe" --scrypt -u "username" -p "password" -o "http://fc.ltcoin.net:6666" - remove the extra " after .exe - wait, youre not actually using quotation marks for each value are you?

High thread concurrency would do it.
Delete *.bin files and try something low like:

Quote

-w 256 --thread-concurrency 4096 -I 12

That's my basic desktop usage 7850 settings, 7870 would handle it fine if the card is working fine.
7870's have 1280 shaders as well, but you already tried without that flag.

I have 2 x 7870XT Joker cards

My command line:

cgminer.exe --scrypt -o xxx:3333 -u user.1 -p x -o xxx:3333 -u user.1 -p x -I 12 -g 2 -w 256

getting 450 kh/s per card, total 900 kh/s. You could push them to 1000 Kh/s but they get too hot in my case.

I am doing the finetuning with MSI Afterburner

tried both, nothing changend - cgminer still crashes with scrypt (bitcoin is still working)

Apart from the slightly high value on thread concurrency and the fact that 7870xt doesn't have 2048 shaders, I can't see anything wrong with those settings. Did it connect to the pool? Is the OpenCL box checked in GPU-z?

yepp, got that but changend nothing - also checked is, openCL is available

Looks like I have a big driver problem - in case of mining other coins I would set up a new system, looks like that the settings are not the problem

crash details:
name: APPCRASH
appname = cgminer.exe
fail-modulname = amdocl.dll

How many memory instaled on your PC?
Double it and try again

installed 16 GB DDR3 1600 - should be enough xD

Might be that the card isn't getting enough power. Does it show 99% in CCC?

that could be the right way - ccc show 0% activity while scrypt - but 99% while sha256 - together it goes up and down - seems like scrypt doens't start the engine
any idea how I can force my card or the miner to go up to 99% ?

it would help if you pasted your command line here, sans private info.

I'd tried near every command, but maybe I missed one out

Why did you install 2 different catalyst versions?

bit by bit - so not 2 at the same time Wink

Hello,

while reading the subject you get my problem.

I mined with guiminer(scrypt version), cg miner 3.1.1 and minerd - nothing changed
I installed amd catalyst 12.11 and 13.4 bit by bit, but nothing changed

Can someone help me finding a solution?
