Title: LOW hash on 7790 Post by: Kinetic915 on May 21, 2013, 07:45:46 AM Hello all,
I am mining with a 7790 with the following settings: --scrypt -o stratum+tcp://minewdc.dontmine.me:3334 -u Kinetic915.2 -p 1234 --worksize 128 --thread-concurrency 8000 --intensity 17 -g 1 -d 0 clocks 830 and 1500 I hash around 25.5 which seems a bit low even for this card. Any suggestions? Thank you! Title: Re: LOW hash on 7790 Post by: HellDiverUK on May 21, 2013, 10:17:55 AM Eh, that's broken. A HD7750 is doing 130K here, standard speeds. Similar to a HD7770.
Try turning intensity down, the HD7750 craps out and crashes the video driver if I run it anything above 15. 15 runs OK, only crashes once or twice a day. 12 is stable 24/7 but only pulls about 110K. I run it at 15 during the day while I'm at the computer, then 12 during the night when it's unattended. Title: Re: LOW hash on 7790 Post by: Kinetic915 on May 21, 2013, 03:52:47 PM Eh, that's broken.

I was trying these settings on the wiki which supposedly worked for someone else -I 17 --worksize 128 --thread-concurrency 8000 --gpu-engine 830 --gpu-memclock 1500 -G 1 ill keep trying thanks. Any other suggestions are appreciated.

What hash do you get? What drivers do you have installed?
Title: Re: LOW hash on 7790 Post by: Kinetic915 on May 21, 2013, 04:26:43 PM I installed the suggested 7790 performanced drivers on amd. anyone else got these installed?
Title: Re: LOW hash on 7790 Post by: Mhash pipe on May 21, 2013, 05:05:20 PM Don't use the 7790 drivers... They didn't work well for litecoin mining for me and caused bitcoin mining to crash when I added -v flag.
I'm using the latest beta drivers (13_4 I think) and the latest AMD APP SDK. I just installed my cards two weeks ago. I get 246 khash/s using the wiki settings. I use guiminer-scrypt and pull down the 7700 and change the intensity to 17 and worksize to 128 and use the flag --gpu-fan 55 --gpu-memclock 1500 --gpu-engine 830 |
