I don't speak spanish.. but I recommend using a powered x1 to x16 riser ribbon cable!
thank you for the quick reply!
i have 3 x radeon hd 7950 on the system now on the x16 pci-e slots. will it work if i add one more in the pci-e x1 slot? will they work all together well?
No prob!
Yes, you should be able to add that 4th card in without any issues at all.
I sometimes have driver issues when adding cards (need to uninstall cards, then do a fresh install) but that's the only prob I have.
