Hey everyone, I'm new to BOINC and Milkyway@home and would really appreciate some help. I have it running fine I think as I see activity on all 4 GPU's, I'm just looking for some help with settings. Specifically, what command line settings should I be running for the dual 4870x2's. Thanks so much for any help!

I'm currently having trouble with my Gainward 4870X2 on its own. Can't disable crossfire on it, so it's using only 50% of each GPU.

The way most of us have done these X2 cards, is to goto CCC and disable CrossfireX. Then put a dummy plug on a DVI port for each GPU so it's enabled by windows. Then just run MW as normal. Then it'll run all the GPUs as it should.

Again, usual setup is Catalyst 8.12 and the 0.19f application.

Like I said, my problem at the minute is that I can't disable CrossfireX between my two GPUs on one Gainward card.
