Hi

I have a Z97X-Gamning 5 board and have 4 GPU (HD7970) running nicely in x16 slot and the 3 x1 slots in Utbutu 14.04

Problem is when I add a 5th GPU to PCIE x4 it turns off the x1 slots I know that but cant seem to over ride it in the BIOS, but when I add another GPU to the remaining x8 slot the machine wont boot.

Any pointers...

Cheers

Rob
Your motherboard likely doesn't support using all of the slots at once. Many boards we've tested in the past only support 4 GPUs. Other possible issues: you do not have enough PCI-e lanes on the CPU and your board doesn't have a PLX chip; you do not have 64-bit PCI-e addressing enabled in the BIOS, or your BIOS does not support 64-bit PCI-e addressing.
