One of my friends is getting his hands on a 19-slot mobo... Funny thing is he has no idea how to set up the damn thing.
What's the latest on Windows' support for more than 8 GPUs of the same brand? Would I have to set him up a Linux distro if he wanted to run 19 GPUs on that mobo? Or is 16 doable under Win10? I wasn't recommending that mobo to him due to the major point of failure risk... but hey ho he went for it. Now I can see myself setting it up for him...

That board needs 6 x P106 Mining card, as pre-req to work.
See full rig setup by BBT here -

Does it NEED those P106's though? Can it run 16 cards (8 nvidia and 8 AMD)?
If I remember correctly BBT started with p106's and started adding normal GPU's to max it out instead of the other way around. I would check the latest BIOS/chipset drivers for updates on compatibilty, but 8 normal Nvidia and 8 amd should work fine, or start with 13 AMD and add Nvidia one at a time. The worst part of that board is the crazy loading times and then trying to load OC values after that. Seems more feasible to stick with 8-13 GPU motherboards.
I agree, and that's what I told him. Easier to manage 2-3 smaller mobos than this juggernaught which will probably end up being a massive pain in the ass.
Everyone's jumping onto the mining bandwagon nowadays. Got colleagues at work flocking to me as they hear I'm into crypto. Helped one of them ordering parts. My plumber/electrician has setup a rig and I was walking him through how to get his mined coins out of Suprnova into his Coinomi wallet!
