Title: [Feathercoin | Scrypt] 7870xt does only 15KH/s - Bitcoin works 400MH/s+ Post by: vanycon on June 10, 2013, 11:00:07 PM 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?

Does it show 99% in CCC?

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 Title: Re: [Feathercoin | Scrypt] 7870xt does only 15KH/s - Bitcoin works 400MH/s+ Post by: baka on June 11, 2013, 09:16:54 AM no one can help you without seeing the settings you're using.

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 Title: Re: [Feathercoin | Scrypt] 7870xt does only 15KH/s - Bitcoin works 400MH/s+ Post by: baka on June 11, 2013, 11:23:18 AM 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?
Title: Re: [Feathercoin | Scrypt] 7870xt does only 15KH/s - Bitcoin works 400MH/s+ Post by: trdiablo on June 11, 2013, 11:44:13 AM 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 Title: Re: [Feathercoin | Scrypt] 7870xt does only 15KH/s - Bitcoin works 400MH/s+ Post by: TheSpiral on June 11, 2013, 11:48:06 AM 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.

Will try it at home in few hours Title: Re: [Feathercoin | Scrypt] 7870xt does only 15KH/s - Bitcoin works 400MH/s+ Post by: Bitcoin.Greece on June 11, 2013, 04:37:28 PM How many memory instaled on your PC?
Double it and try again Title: Re: [Feathercoin | Scrypt] 7870xt does only 15KH/s - Bitcoin works 400MH/s+ Post by: vanycon on June 11, 2013, 11:01:19 PM How many memory instaled on your PC? Double it and try again installed 16 GB DDR3 1600 - should be enough xD Title: Re: [Feathercoin | Scrypt] 7870xt does only 15KH/s - Bitcoin works 400MH/s+ Post by: vanycon on June 11, 2013, 11:47:16 PM High thread concurrency would do it.

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 Title: Re: [Feathercoin | Scrypt] 7870xt does only 15KH/s - Bitcoin works 400MH/s+ Post by: Rawted on June 12, 2013, 03:35:30 AM C:\Miner\cgminer-3.1.1-windows\ 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 - shaders wrong 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 - thread concurrency wrong and extra " after .exe 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?

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? |
