LOW hash on 7790

[Kinetic915]

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!

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.

damn okay.

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.

Hmm there must be another problem then as I tried those settings.  What hash do you get?  What drivers do you have installed?

[Kinetic915]

I installed the suggested 7790 performanced drivers on amd.  anyone else got these installed?

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
