4870x2 problem

hey everyone! I am new at folding. Just tried to set up this amazing thing, but it's not working properly. I run smp,gpu0,gpu1. smp and gpu0 work fine, but gpu1 no way. I set forcegpu on rv_700... simply said, can't fold on both cores. still got the same thing like: "at present your GPU is not supported or you need a current driver. you may wish to consider running our standard client, which you can download at foldin.stanford.edu"
I got latest drivers installed yesterday.

Any idea? thanks

You may need to disable crossfire in order to fold on both GPUs. I am not an ATI expert so I am not sure if that will work. You can also try using the GPU3 client if you have not tried that yet.

I am not sure what you mean now, because this is 4870x2, no 2x4870. its single pcb, and crossfire bridge is on board, you can't disable crossfire in CCC as you could with two GPUs. I found the same answers in other discussions, but I think its impossible. The question is, how people fold on dualcore GPUSs than

We are use to nvidia GPUs personally and the Nvidia control panel lets you turn off SLI so the multigpu card can work as 2 individual cards regardless of it being on one pcb or not. This is what he was getting at. We have never used ATI and thus dont know how to use CCC.
