    there's a certain setting in the bios that allows the m.2_2 to work, but it will make your GPU run at x8 speeds. I think it's better off just using the first slot and the last two slots if you can.

    i too have just noticed this as i just got my maximus xiii hero with i9 11900k cpu.. i have 4 m.2 slots on mb.. since im running a 11th gen cpu im able to use the m.2_1 slot.. and like was said if you enable the bios under advanced/onboard device config.. pcie to say pciex8+pciex8+ m.2_2 your x16 slot turns into a x8 slot.. so i put my other nvme drive in m.2_3.. i am posting my own thread on what im running into on my hero board.. adding cards disables all sorts of stuff.. mostly sata drives. but yes.. if you enable the m.2_2 slot your x16 turns into an x8 which for me was unacceptable since i just spent a ton of cash on a evga 3080ti ftw and didnt want it not running at what it is supposed to run at. i believe all the 590 boards are this way... hope that helped.

    You simply fail to understand how PCIe lanes allocation works.

    No.
    The Pcie lanes are given by the intel 11th gen cpu that has 20 lanes. not the board

    Note: the board read pcie4.0 on the gpu, but will run in 3.0 speed with 10th gen.
    Learn, Play Enjoy!
