Hey All, I need some help.
Using an ASUS Prime Z270-A mobo and attempting to expand to 7 cards.
I have the 7th card in, but I get error code 43:
"Windows has stopped this device because it has reported problems. (Code 43)" on any card connected to PCIEX1_4
I think it has something to do with the PCIEX1_4 slot because each card works in every other slot but that one.

I don't think it's a riser or gpu problem because each works great in a different slot except
PCIEX1_4.
Has anyone come across this before? Do i have to do something to the motherboard? There is the SLI Bridge that came with the MOBO as well, do i use that? Do i need to reset my virtual memory maybe?
Thanks in advance and any advice is greatly appreciated.
