Hi i have a similar issue. Can i use the two pci-e slots of this motherboard simultaneously for mining? The board does not support crossfire and so i was wondering why they put two slots there for no purpose.
Any help is appreciated.

Solved. I think. I need crossfire cables eh?
Yes, I know the Days of GPU mining are numbered... buts its still all profit to me since I've got loads of machines running all day for my biz in any case.
I just assembled, after 14 painstaking hours in a southeast asian knockoff mall, to put together an extra desktop for my company with the best available resources.

Now, Guiminer is READING 2 cape verde GPUs, but while mining the second miner is only doin 50 mhash (haven't overclocked yet as I want to solve this first.
Is it a memory issue?
Do I need crossfire cables? The manual said nothing about needing crossfire, and my other rig on a asrock 990 doesn't need crossfire.
Any help, tips, advice would be much appreciated.
Thanks!
