7x Mobo

[techno8k]

Hello everyone. I want to build another mining rig, and I want to run 7 Radeon cards this time on one mobo. Is anyone running on a good mobo with 7 PCIe slots that supports 7x Radeons that you would recommend?  I don't want a list of boards with 7x PCIe. I know for a fact that just because a board has 7 PCIe doesn't mean it will run 7x GPUs. I want a board that has been confirmed experimentally to support it. Thanks
