Seems to be a lot of problems with this board. See the large# of 1-star ratings on this Amazon listed product.

This board has lane sharing with the PCIx16 if you use any of the 2 M.2 slots that share bandwidth btw. The effect isn't all that much, but just something to be aware of. Most X870E boards have this problem because AMD mandated USB4 lanes go off the CPU.

As far as I'm aware, only MSI and AsRock got around it. MSI Tomahawk/Edge TI/Gaming Plus Wifi and Asrock Nova/Taichi/Taichi Lite are the only ones I'm aware of that you can use all M.2 slots without taking lanes from the PCI slot.

wow, really? I would expect that by 2025 we wouldn't have $300+ motherboards that still lane share like that.

Yeah unfortunately...it's due to AMD's USB4 mandate.

B850 is where it's at if you don't want any lane sharing. My Gigabyte B850 Ai Top has been great, solid as a rock. Far more sensible lane splitting arrangement than nearly all x870 boards.
