I’ve been struggling to find an AM5 board that can run three MI50s at 4x. This is perfect thank you.

Him are you sure about some of the PCI slots? I think some marked as 4x get downgraded to 1x on these boards…

Further edit - this maybe accurate - how are you getting this / confirming it?

I would normally figure this out by reading motherboard manuals. Which for SKUs you can buy standalone tend to be on the manufacter's site with no account/paywall. They tend to include all the "if you populate this slot you lose xyz" language. Along with how to change PCIe lane bifercation in bios if nessesary.
