   Hello,

I wish to connect two nvidia 1080 ti GPUs on  z270 pro4 motherboard.

I use PCIE 2 (x16) and PCIE 4 (x2).

PCIE5 and PCI1 are not occupied.

The computer will not start with bth connected, in fact it wont start when a GPU is connected to PCIE4 (it works fine when one GPU is connected to PCI2E).

Is that possible - anything specific I should be doing?

Thanks!
RFat
