Reached 660khash @ 730/810/0.95V  Cheesy.
The one who maximises my hash at 0.95v will get the reward Tongue

I'm also fighting with 5970, those GPU are not easy... Can you tell me which Catalyst and AMD-APP-SDK versions are you using and which cgminer options?

For reduce the VCC you only need to add the next option to the cgminer.conf file

    "gpu-vddc": "0.95"

But in my tests less than 0.97 gives very low hashrate... however maybe I messed it up in some other point.

I am using 13.1 and 2.7 sdk.
Yes i have added that option in bat file not in conf file.

Hello guys i have a miner consisting of XFX
1.6990 black edition
2.5970 black edition

Which is running @ 1.732 Mhash/sec.
6990 @910/1360/1.110v 491hash per core
5970 @820/1200/1.050v 373hash per core

I want to bring 5970 lower on 0.95v. Please tell me cgminer settings which will provide me max Mhash/J. Do tell me intensity TC g, work, etc etc.

1.05~1.10 is the lowest you can probably go and still get decent hash rates. Otherwise, running lower, you'll lose a good amount of hash rate.

You probably can go 850 mhz core on the 5970. Maybe 950 core on the 6990.

TC=8192, g=2, Worksize=256, I=18.

I want 650+khash on 0.95v

5970 @ 715 0.95v and 765 have helped me to reach 590. Testing TC now

700~725 khs on 0.95 is about the average at that voltage.

Can you please quote the exact settings of cgminer to get that much hashes @ 0.95v???
