I suggest that you put the dialogic PCIe card in the x16 slot.
Because once the x8 pcie slot is occuped, the x16 slot downgrade to x8 automatically, the two slots are both x8.
we can't as on x16 we have video card
but IF we use usual PCI video card (mother board has 2 PCI slots) it does not help....
Dialogic cards (one or two) works in x1 or/and x16 slots but as only we add third card to x8 - we have problem described in first message:
- either can't see card in bios
- start dialogic service hangs windows, only hardware reboot helps
I am sorry amd I think only intel can help you solve your problem.
I am also confused for GTX 460 no display output after I updated a new mother board bios
