Do you think I 'd be pushing it with my second eGFX with 1070?

I have only tried one eGPU on desktop motherboard because there's only one TB3 port. It would be cool to see two eGPUs!

I had opened a ticket with Gigabyte ... but they weren’t much help... when I reported back that the boot setting in the BIOS was key they said that they thought that setting auto updated the first time anything thunderbolty was plugged in... and were surprised I had to manually set it. Generally everything Thunderbolt seemed to scare them.

Fantastic troubleshooting thread!

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Question... I have to two more 1070s kicking around that I'd like to get into the pipeline for Redshift rendering... what would be a decent PCI-E card and enclosure setup for 6 cards externally? I get confused by the whole non-TB world 🙂

Rendering compute only.

Must be the Macboy in me.

Thanks!

I had a swap around - put two 1070s inside the PC and the two 1080ti in the eGPUs - all working fine and the temps inside the case staying a bit lower now. Do you thing there's enough capacity to put another 1070 inside or am I out of lanes ?
