Width of both cards are differents. RTX is a 3 slots, and GTX is 2 slots.
Width of PCIE1 is 3slots, width of PCIE3 is 2 slots, and I have an ASUS Essence STXII sound card on the last slot.
Then, I can't swap cards.

At compile time, it's a beast. Can't wait for a Ryzen 3950X :)

Hi all,
I have a very powerfull X470 Taichi Ultimate R7 2700X Linux station.
I do have 2 GPUs, an old GTX 980Ti, and a new RTX 2080.
The larger RTX2080 is plugged on PCIE1.
The thinner GTX980Ti is plugged on PCIE3.

At this moment, the system starts on the RTX2080 slot 1.

How can I start the system on the GTX slot3 ?

Thanks for your hints
