velvetlynx3 said:It’s pretty strange how they flipped their decision, especially since there isn't even an option in the BIOS to toggle it for lanes 1, 2, or 3... I haven't been following this closely, but does anyone actually know why they were messing around with the PCIe settings like that?
The most likely reason is probably this:

Here is the history of the BIOS updates:

I’m guessing that once they hit BIOS version 5220, they stopped mentioning "removes Gen 4 support when using Ryzen 3000 CPUs" because it’s just assumed now... talk about being lucky, right?
Though, looking back, I suppose I was actually quite fortunate that I didn't pick something like a 6650XT, otherwise I would have been stuck dealing with a GPU running at PCIe 3.0 x8 speeds.🤦
I ran a Blackmagic RAW speed test and the results confirmed it: 42 fps on x8 versus 66 fps on x16, so there is definitely a measurable impact there...
