Thanks for pointing it out.
Sorry for wrong info. You are correct. The board has 2 x16 and 2 x8 with
one native x16. Anyway, as I am planning on single-gpu runs, that should
not be an issue.
Good news is that machine is rock solid and going non-stop for the past 3
months since I built it ( except some reboots due to OS updates)

Does not look like. It's saying "Providing 4 PCI Express 3.0 x8
connectivity". Details in section "expansion slots" at
