Title: Newbie Needs Help with 7950....stales or stuck on startup Post by: Draxus on April 18, 2013, 03:56:32 AM Hey all,
I just got my sapphire HD7950 and hooked everything up. I am now having serious issues... I am attempting to mine Litecoins, I got Guiminer script, I updated the drivers for my card from AMD's website, catalyst sweet 13.1 So if I do the Default High Intensity Setting I get a 530 Khash/s rate, but for my shares I had 27 accepts and 49 stales. I dropped to low intensity and got 286khash/sec and 9 accepted and 25 stalls. Now this only worked with pooledbits mining site, if I try to connect to anyother mining site I get stuck at "starting..." Any help greatly appreciated ;D Title: Re: Newbie Needs Help with 7950....stales or stuck on startup Post by: robi on April 18, 2013, 05:08:44 AM post your entire config so we can see where you went wrong.
Title: Re: Newbie Needs Help with 7950....stales or stuck on startup Post by: ks3rv3rg on April 18, 2013, 05:11:36 AM You may want to try cgminer. There is a ton of info on easily setting it up to mine litecoin. I have x3 sapphire 7950 and I'm getting about the same hash with litecoin. 550-600~. The regected thing may have to do with the pool you're using. Or are you solo mining?

Title: Re: Newbie Needs Help with 7950....stales or stuck on startup Post by: Draxus on April 18, 2013, 05:24:25 AM have you tried using reaper? I seem to have great results with my 7950s I actually was just setting up reaper, I am getting about 510 khash/s with it and 0 stalls...so I guess GUIminer is my problem. Would you mind posting your CONF file for it? Here is mine, just wondering if I should change anything: host ltc.kattare.com port 9332 user Draxus.1 pass xxxxxxx protocol litecoin worksize 256 vectors 1 aggression 20 threads_per_gpu 1 sharethreads 32 lookup_gap 2 gpu_thread_concurrency 21712 Title: Re: Newbie Needs Help with 7950....stales or stuck on startup Post by: Draxus on April 18, 2013, 06:34:40 AM Ugggghh Spoke too soon....
So it will run perfect for about 10 minutes....then it starts getting all stales (up to 20%) then my driver crashes...now the card never got over 75c Here is my reaper and litecoin conf files: kernel reaper.cl save_binaries yes enable_graceful_shutdown no long_polling yes device 1 mine litecoin host ltc.kattare.com port 9332 user Draxus.1 pass xxxxxx protocol litecoin worksize 256 vectors 1 aggression 20 threads_per_gpu 1 sharethreads 32 lookup_gap 2 gpu_thread_concurrency 21712 Title: Re: Newbie Needs Help with 7950....stales or stuck on startup Post by: robi on April 18, 2013, 06:37:51 AM the thread concurrency seems a bit high.. but I have a lower end card..
Title: Re: Newbie Needs Help with 7950....stales or stuck on startup Post by: LordTheron on April 18, 2013, 08:04:49 PM my 7950 overclocked runs at 620mh/s. guiminer works out of the box. Ive tried to play with flags but for me works best with default settings.
Title: Re: Newbie Needs Help with 7950....stales or stuck on startup Post by: Saka on April 18, 2013, 08:26:55 PM The configuration looks spot-on. I'd try a separate pool. I'm running 4x Radeon 7950's without a problem out-of-the-box via GUIMiner.
