Pcie lane advice

[TheGodlyGecko]

Hey all,

I have an Asus Rog b650e-f motherboard and was wondering if I add a 3rd m.2 SSD will it run at lower speeds because it's the 3rd slot, also it makes note somewhere that it takes up pcie lanes on a slot somewhere when In use.

Does it mean that it would reduce GPU performance or is it the pcie lanes of the 2nd slot and not the main GPU slot?

Page 1-10 of the manual:

The M.2_3 slot shares bandwidth with the PCIe 4.0 x16 slot (supporting x4 mode).
When the M.2_3 slot is operating in PCIe mode, the PCIe 4.0 x16 slot will be
disabled

The PCIe 4.0 x16 slot (with just x4 lanes from the chipset) is the lower one.

Thank you very much!
