Hello,
Cliffnotes version: when I enable crossfire, screen goes black, does not come back on until manual reboot that disables crossfire. Endless loop.
I got my 2nd 5970 today so I naturally wanted to enable crossfire.
First thing I did was run the Heaven benchmark on my single card to verify it's stability. It handled the benchmark like a champ.
Secondly, I unplugged my original 5970 and plugged in the new one. I then ran the same test on the new card. The new card performed slightly better, but I attributed it to background processes that were not running.
Anyhow. I shut down my PC, put the old card in the 2nd slot on my motherboard and attached the Crossfire bridge. PC booted fine and I got into Windows. Opened up CCC and enabled crossfire by checking the box. Screen went blank and the noise sounded for "hardware disconnected". The screen stays blank and does not go to Windows or anything else for that matter.
After doing a hard reset using the reset button, everything loads up fine and I get back into Windows easily. The only problem is that now when I go to CCC, the box for Crossfire is unchecked again and I have to go through the same process.
I'm not sure how I can test to see what the deal is. I tried swapping the VGA cable to the bottom card and tried all the different ports, still no picture. I also swapped out the Crossfire bridge and tried two other bridges that I had (both ATI CF Bridges). Same thing happens.
Any ideas as to how I can test this to narrow down what the issue may be?
I appreciate any help that you can give, I'm getting back into the "game" with benchmarking and I'd really like to be able to run two 5970s with my new i7 980x.
Thanks all.
