Title: 7850 Slow Shares? Post by: fyubr on April 16, 2013, 10:33:06 PM I just bought a new radeon 7850 and I can get around 350-400 average hash running cgminer
But im connected to netcodepool and it says i'm only running max 50khs even after 3 hours of running it. My bat settings Code: cgminer --url http://netcodepool.org:8337/ --user fyubr.1 --pass x --scrypt --thread-concurrency 9999 -g 1 -w 256 -I 20 --vectors 1 Does anyone see anything I might have wrong there? FYI I am trying to mine litecoin and have 4gb of ram installed. Thanks to anyone who can help out. Title: Re: 7850 Slow Shares?

Your CG - pool variance can prolly be helped by reducing your -I a bit as it may be too high since only 50 on pool. Also, where did you decide the 9999 for concurrency? Is your card the 1gb or 2gb version? If 2 gb, maybe try 16384 or if 1 gb try around 12288.
See if lowering the -I and changing concurrency helps. Title: Re: 7850 Slow Shares? Post by: fyubr on April 16, 2013, 11:35:41 PM Still new here and to mining, but maybe can help some.

The 9999 was just a random number inbetween high and low Code: cgminer --url http://netcodepool.org:8337/ --user fyubr.1 --pass x --scrypt --thread-concurrency 12288 -g 1 -w 256 -I 1 --vectors 1 how does that look? (thanks for the help btw) EDIT: I tried what I posted above and it keeps crashing cgminer Title: Re: 7850 Slow Shares? Post by: Protagonus on April 17, 2013, 12:39:07 AM hmm, well 20 - 1 is a lot!. maybe try something like this
cgminer --url http://netcodepool.org:8337/ --user fyubr.1 --pass x --scrypt --thread-concurrency 12288 --intensity 16 --workspace 256 -g 1 See if that works Edit: if you you haven't enabled higher concurrencies yet; Open command prompt and type: setx GPU_MAX_ALLOC_PERCENT 100 and hit enter Title: Re: 7850 Slow Shares?

Title: Re: 7850 Slow Shares? Post by: Protagonus on April 17, 2013, 07:11:16 AM Hmm, is your card 512mb of ram instead of 1gb? If it's 512 by chance; try 8092. IF it IS 1gb maybe just try removing the -g flag; 12288 should be np for 1gb.
