MB DX79 SI: Is it possible to have a second graphics card in PCI-E-Slot "D" (last/5th Slot from Top)

Hello,

I've installed my new graphics card (GTX970) - as recommended - in the first PCI-E-Slot (named "I" in the Product Guide). Because of space issues I've installed my old graphics card (GTX570) to the last PCI-E slot, named "D" in the Product Guide. Although the fans are rotating and the card is getting warm the old card is not recognized by the BIOS. Is the third PCI-E-Slot not suitable for a graphics card? Or is there another problem? Any ideas?

Thanks in advance.

The third x16 (actually only x8) PCIe slot is indeed usable for a graphics card. Are you connecting the two boards together with an SLI bridge connector? I am unsure that two independent graphics cards will work otherwise...

After I've checked once again all connections (4th time) everything works flawless. It was obviously my fault. Sorry.

By the way: To have two different graphics card in a system (without sli/crossfire) works - until now - without any problem. Even driver installation was easy. The nvidia-package installed both drivers in one go.

Anyway, thanks for your answer and sorry for your effort.
