Can't get Furmark to work in Crossfire mode...
I'm running the multi-core Furmark, and it is only stressing GPU3 and GPU4, so GPU1 and GPU2 aren't being stressed. Every other stress test works with all four processors, so I can't figure out what is going on. I don't have Catalyst Control Center enabled, as I'm just using MSI Afterburner to handle fan speeds and such... so I have Catalyst drivers, just no utilities.
I really want to use Furmark as the "base" stability test, i.e., the one that I initially run for really short time frames (maybe two minutes) just to see if there is no way the overclock will work. Furmark sends my GPUs straight to 99% capacity; the best I can get on others is 92% (of course, maybe that will drop if all GPUs are involved).
