Heya!

I write this thread in succesion of my "question about 2 sound blaster solutions" thread.

There i wrote in the ps, that i might gonna try switching pcie generations in the bios.
This i did now, but i find things a bit strange.

Ive read on Reddit and elsewhere that you can only swap the generations of all of them in one go.
But on the 3607 bios of the asus rog strix b550 wifi-ii it seems that at the advanced > onboard devices page, i can set everything of them seperately. And thats where my concern lies.

When i change all 3 of the pcie x1 lanes from auto, to gen 1, will they really only operate on gen 1 mode, and are not maybe still be in either gen 2 or gen 3?
And when i set the pcie x16 main lane to be in gen 4 mode (where my gpu is), will this not effect the other pcie lanes?

I mean, from what ive read online, when you wanna lower the pcie generations, then every pcie lane is affected, and my bios page claims you can set them individually. So whats the thing here?

Thanks in advance.
