Ryzen motherboards question

[DELTAprime]

I'm thinking of getting a Ryzen 2700 or 2700X along with a Crosshair VII motherboard provided the reviews in a couple of weeks are positive. One issue I run into on my current Intel Z270 based board is I'm using up all HSIO lanes and so some PCIe lanes are disabled. I know we don't know about X470 yet but on the X370 AMD boards were there situations where the motherboard would turn off features or are they designed in such a way to never disable ports and slots?

You mean disabling SATA ports when some M.2 ports are used? Occurs on X370, doesnt seem to change on X470.

Oh ok, so at least on the X370 boards would a GTX 1080, Elgato 4K60, Samsung 950 Pro, 4 SATA drives, gigabit ethernet and about 8 USB devices be ok or would things start to get disabled?

 

I have no idea if AMD is using their own HSIO implementation where everything is shared or if every protocol is separated.

With Ryzen (even B350), one M.2 port gets it's own 4 PCIe lanes from the CPU. Therefore, ports wont get disabled until you start using more than 1 M.2 ports.
