The pool seems to be still hashing but site is down
both http://binarycoins.eu/ and https://btb.binarycoins.eu/

With two 7950s, 750W would do, but 850W is better.  Remember, you want this to be stable long term.

By the way, that smell, everytime it happened to me, it was my power supply.

 GPU 1: 73.5C 2551RPM | 427.3/443.0Mh/s | A:8 R:0 HW:0 U:4.39/m

Each column is as follows:
Temperature (if supported)
Fanspeed (if supported)
A 5 second exponentially decaying average hash rate
An all time average hash rate
The number of accepted shares
The number of rejected shares
The number of hardware erorrs
The utility defines as the number of shares / minute

I think this problem is fixed now that I reinstalled the drivers.  
Thank you everyone for your help
No i was not using crossfire.

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
