Been up and running a few days now. I give it to the ROG team on this one. My c6hs were a nightmare on launch but I only had 1 issue with the zenith that was resolved flashing a later bios. On the shipped bios a 2nd gpu in slot 3 would bring a b2 vga bios error. That was sovled with a bios update. Other than that EVERYTHING WORKS. Aura, fan control, memory profiles. Felt like I was building on a tested intel platform lol.
Only thing now is to wait for more 128gb ram kit reviews w/ the 1950x, so far people have been hitting 3066/3200 with it at max, though its still Early adoption and motherboard updates are starting to come out, Gig was confirmed to support at least and asrock, hopefully the new Asus updates fix that. I really wanna grab the 128gb kit, though I'm worried about still being able to hit 4.0-4.2 on it, as easy as EK claimed it was I'm sure w/ the IMC stressing it'll plank on that, hopefully not, or I'm stuck going 64gb.
Direct from the manual:
4 x PCI Express 3.0 x16 Slots (PCIE1/PCIE2/PCIE4/PCIE5:
single at x16 (PCIE1); dual at x16 (PCIE1) / x16 (PCIE4);
triple at x16 (PCIE1) / x8 (PCIE2) / x16 (PCIE4); quad at x16
(PCIE1) / x8 (PCIE2) / x16 (PCIE4) / x8 (PCIE5))*

He shows the backside of the Fatal1ty X399 Professional and you'll see they are solder points for X8 lanes to two X16 slots
I get information is trying to be put out but multiple people have already posted the same information, I apologize that my comment caused this many duplicates... Already multiple comments prior of people explaining/showing, my comment after was merely poking fun at how they advertised it and that a rep at the company specifically stated that all were 16x capable, and then it further went into explanation.
