I am at my wits end on this. I have been fighting with this Razer Blade Stealth and Core X Chroma for almost 2 weeks. Alternating between "Code 43", "Code 31", Blue screen error "Video TDR Failure" and Blue Screen error "DPC Watchdog Violation". If Razer support is watching, this is covered in Case #200517-001119. A lot of good that has done me. I will get it to work, and after between 2-5 hours it will freeze, I will reboot and it will come back with an "Code 43" error. After a few hours of fiddling attempting all the below: - Disable the eGPU - Uninstall the eGPU - Reinstall the drivers for the eGPU - power up the eGPU and the Stealth at the same time I have not been able to replicate a pattern that consistently works, it is very much act and pray each time. Once I get it booted with no error on the eGPU, I will get some green alien looking artifacts.
