The long story:
So i am running ubuntu 11.04, i had 3 6950 GPU's but couldn't run them stacked -sandwitched- the heat was killing the top card so i ran two GPUs and leaving the third on the box, and ordered the 16x extender and 14 days later -that's yesterday- i got it.
I was kinda shocked that the extender is so fricking short!!!!
Couldn't really get the GPU away from the MOBO, and since the crossfire bridge is short aswell i ended up laying the GPU on it's side...
Anyway i crossfired them and re-initiated X to rebuild the conf file then rebooted.
The third GPU was detected and i ran three instances of phoenix and everything was cool.
After many hours i came back to find only two phoenix instances have 1000+ shares and the other have only 100 shares, and no error messages, and for some reason i can't ctrl+c the bash screen..
Did it again and waited some hours -actually was @ work- and checked it again, same problem.
Note #1: GPU #0 is always fine, GPU #1 is the one doing that, GPU #2 is fine.
Note #2: GPU #1 -second- Won't get flashed, unlike the other GPU's
Note #3: The second -#1- GPU was working fine without adding the third GPU.
Note #4: The GPU's are identical MSI R6950 Twin Frozr III cards.
Note #5: GPU #1 -second- always has the lowest temp, and it is in the bottom position.
TL;DR version:
After added a third GPU the second one won't function properly and it won't mine after a certain time.
Thanks for any help on this.
