GDS

yes I agree about separate all OS and ProxMox

How much space would you recommend for Proxmox? 

website says 1 Gb mini, and you have 256Gb (if I remember) 
 

concerning a SSD or an USB flash drive I don't see any huge differences

(the last one can have 440/330 in read and write and there fits perfectly on the back of the computer) 😉 
So i will go through a speedy USB key

@GDS

Could clarify better your motherboard model?

Is an Asus?

because Aorus master should be gigabyte 🙂 🙂

 

you are DEFINITELY right it is a Gigabyte AORUS MASTER 
I am soooo used to have ASUS for Hackintosh that I wrote ASUS and not GIGA 😄

Thx a lot 

So i am studying your flow to have everything fine

About ASUS, GIGABYTE, I don't think it will make crazy troubles, let see how it goes but I am pretty confident concerning the compatibility

I will go through CLOVER that I know well and I love, OpenCore looks super nice but i guess too early for me to use it 

and with CLOVER I can overclock the Radeon VII (Power Table Generator injected in Clover) to have a beast on water 😄

About dual GPU yes tricky tricky but I love challenge and I guess it can help the community:

I thought to approach the problem in clean way, I mean I need the 1080Ti only for Win10 and the radeon VII only for Catalina 

I can of course put flags in CLOVER to not activate the Nvidia so no conflicts as CATALINA will consider the 1080Ti not existing at all

and having on WIN10: 1080Ti and Radeon in Windows 10 but this solution will be a huge source of conflicts for sure soon or later 

but I thought to use PROXMOX for each VM:

activate the PCI of the radeon VII for the CATALINA VM
activate the PCI of the 1080Ti for the Win 10 VM

I guess it is the cleanest way, what do you think?

I have a tiny question:

i am not a Linux expert at all, and I ask to myself which hardware configuration (passthrough) could be the best:

I have 2 NVMe, one would be dedicated to CATALINA and the other to WIN10
but about PROXMOX? is it possible and reliable to install everything on a 32Gb USB3 key and leave it as it 
or better to buy a new NVMe of 128Gb dedicated to PROXMOX (I dont think that divide one of the 2 NVMe for PROXMOX is good idea 😞 
 

anyway it is very exciting to see how my rig will work and share with the community how it goes 

Hello All,
Just going to say thank you to @fabiosun to this guide, and all of the people who participate on this discussion and have same rig as me

a huge step forward to OS X lovers and Threadripper users

(btw fabiosun, we had long discussions by PM,  years ago on another forum about OS X, I was using a 2699v4 with 2 Titans X, don't know if you remember) 😉

About my rig used for this project:

a 3970X + GigaByte TRX40 Aorus Master 
RADEON VII + 1080Ti Extreme 
128Gb DDR4 2400 

2x m2 NVMe + 2x SSD + 6 x 10Tb HDD 

EVERYTHING will be fully water-cooled in EKWB (thermal dissipation more than 1500W) and OC to have the best of each part! 

Again thx to all and I will post my different steps and results concerning the programs I use:

3D modeling, VR, AR, XR: Blender, Unity, 3DCoat, Reality Capture, ...
But also others like: DaVinci, Adobe suite etc etc
