I am trying to add a 4th card to my mining rigs, but I keep running into some kind of driver issue.

And before you say search: "No results found"

I'm using 6950's, and everything works great. As soon as I boot into windows after adding the 4th card, it looks ok, but OpenCL is not working. GPU-z crashes, Guiminer Crashes, MSI Afterburner crashes with a message about "failed to connect with driver wrapper" whatever that means.

Try using Linux, Linux supports more GPU's.  See if you encounter the same problem.

The problem with linux is getting started. I tried linux but was never able to get a miner working. (Tried with my 5870x2's, not the 6950's yet)

Edit: Alright, I tried the updated guide for 11.04, worked like a charm!

Anyone able to get a 4th card working in Win7???  Is there another program out that allows over/under clocking control and fan control?

can you please point to the post-# you followed in this guide?

I tried #2, but actually something must have gone wrong as phoenix could not start (some opencl issues).

How exactly do you run your miners on Ubuntu? just start them in a terminal by hand, or did you write or found an easy to understand script for that purpose?
