X10DAi (BIOS v3.0a) "PCIe Out Of Resource" warning pop-up after placing 1x GTX 1080Ti (slot 1) + 1x GTX 780 (slot 3).
I had enabled "Above 4G Decoding" in BIOS as below, but still got the same failure and stuck at BIOS screen, please advise.
- Advanced >> PCIe/PCI/PnP Configuration >> Above 4G Decoding >> Enabled
- Advanced >> PCIe/PCI/PnP Configuration >> Exclude Slot 1/3/5 >> Yes
Please noted, set "Exclude Slot 1/3/5" to "Yes", that means do NOT enable above 4G decoding in slot 1/3/5.
You have to set "Exclude Slot 1/3" to "No" to enable above 4G decoding in slot 1/3 (slots you installed GPUs).
Then, MB should be able to boot up well, thanks.
