Hello I have a rig with 3x 7970, Gigabyte GV-R7970C-3GD...
I have tried everything on the internet to get these cards working at 650+, actually they won't mine above 580 kh/s... I have noticed a strange thing running settings that people over here post... I would usually get more kh/s if I remove the -g 2 ! Which people say is needed for speeds over 700 kh/s.. I have Catalyst 13.4, latest App SDK 2.8.
Quite annoying thing, I have spent more than 10 hours trying to set it up but no progress so far !
Currently running at 550 kh/s using stock settings at -I 13

What's your thread concurrency? How much ram does your system have, and how much usable do you have if you right click on my computer and click properties?

Try engine at 1080 and memory at 1500. thread-concurrency at 8192 lookup-gap at 2 and (very important): gpu-threads at 2.

This is very interesting, because over 1085, my impression was that the performance drops.

What's your thread concurrency? How much ram does your system have, and how much usable do you have if you right click on my computer and click properties?
TC 8192, I have 8 Gb ram on win 7 64 bit

It is possible to flash them with modded BIOS. The question is whether they will remain stable at a lower voltage.
