Hi, any folks know if there is some limit?

Every time I plug in a third egpu, whole thing locks ups and reboots.

Hi, this thing has 4x TB3 ports.
I am wondering if I can hook up 3x egpus to this?

What is the speed of the ports? 4x x4?

I can't seem to find this info anywhere about the mac minis.
I know the mac pros can do 4x x4

@ad65, You can hook up as many eGPUs as you want. The limitation is macOS which stops using anything more than 4. I tried 6 eGPUs and only the first 4 eGPUs are usable. Bandwidth is limited by the two Thunderbolt controllers (22Gbps each). You can read more about the state of eGPU on macOS.

@itsage, thanks for the quick reply.

I am assuming if I use all 4 TB3 ports, it will end up being 4x x2 (4x ports with x2 pcie lanes each)

I plan to use bootcamp and windows. Hopefully it helps.
