I have two of these VisionTek 6950s


They use 1.10V each and do about 300-400khs each (scrypt)

I have the stock BIOS


I was wondering if someone had some suggestions to optimize my power usage?  It seems 1.10V is really high.  Could I not somehow lower it to around 1V? Stock bios doesn't seem to allow me to go below 1.10V, so I probably need to flash it.  I tried the flashing to the sapphire 7970, but trying to mine just gave HW ERRORS so that BIOS didnt work on my (non-reference) card

Hi there.  I have a couple of mining rigs working well, but on one of my rigs, it seems that CGMiner is confusing the video cards.  

I have confirmed the same problem, and it even happens in cgminer 2.97 all the way to cgminer 3.11.
I am running 2x7950s here

The problem is, say GPU 1 is overheating, it will downclock GPU 0, and not help the situation, because its slowing down the wrong GPU.

Here is a screenshot of this issue in action


You can see clearly GPU0 is in use (from the temperature), even though it thinks GPU1 is in use.  I have tried gpu-map and gpu-reorder and could not seem to solve the problem.

I am running Catalyst 13.1
