I have a particular issue with my eGPU setup that prevents my Framework from POSTing.
My eGPU enclosure is the Sonnet Breakaway Box 650 with an RX480.
I get a POST code of 12 Green flashes (No hardware problems found), and the POST code bit is BBBGBGGG (11101000).
I’m not sure what to make of the POST code bit, but I can at least get the setup working if I make sure to unplug the eGPU before booting up.
Some other bits of information: I have the Core i7-1165G7 model. Issue occurs on both 3.02 and 3.03 BIOS. I’ve tried ports on both sides of the laptop already. Also, the screen does light up to show a solid cursor. The Framework logo never appears, however.
Don’t know if I’ll be much help, as I left the whole Windows scene in 2018, but I was quoted in that above Thunderbolt 3 post. I’ve tested my workplace’s Akitio Node and my own personal CoolerMaster EG200. The EG200 seems to play better with this device, as I’ve heard other intel-11th-gen laptop owners complaining about Sonnet boxes as well when I was at work.
