Did you look closely in your BIOS ?

Look for a way to let the Operating System take care of the devices Addresses on boot.
Maybe Windows cannot see them because your BIOS could not address everything needed for them to work.
(you could search this way ...)

Hope you have an EFI ...

Think i was looking at correct Motherboard specs...that has Onboard Video .?..

For sure it is disabled in BIOS and win is not seeing that either??

I disabled every device that was non-essential. Onboard video is disabled. There doesnt seem to be a way to manually set resources, but I don't see why this would be a problem? I already have 8 GPU working on identical supporting hardware and OS, aside from 11.12 driver, but this is also with radeon 5000 series and not 7000 series.

You stated that you have 6 cards on the same hardware, but the same OS also?

From everything I have read Windows 7 only supports 4 GPUs.

Also another screencap showing 5 7970 installed and mining. 12.6 driver with SDK from 13.1.
