ASUS ROG X570-F Gaming PCIe Lanes operating mode

Hi,

is it possible to put my M.2 SSD via adapter (PCIe 4.0x4 -> M.2 x4 (PCIe 4.0)) into the PCIe 4.0x16_2 (2nd slot) and PCIe 4.0x16_3 (3rd slot) beside my graphics card and run on full 24 lanes?

In the manual (1-6) it says





















PCIe 4.0x16_1 x16 (PCIe 4.0)
PCIe 4.0x16_2 N/A
PCIe 4.0x16_3 N/A
M.2_1 (PCIe Mode) x4 (PCIe 4.0)
M.2_2 (PCIe Mode) x4 (PCIe 4.0)



I just ask because I don't want to order the hardware if it's not compatible. And I don't want to give it this expensive try.

You got 24 lanes total provided by the CPU. The PCIEx1_1 and PCIEx1_2 slots stay available, because they are provided by the X570 chipset.
