@jendrik_reis a bit more info would be good... what Mac? What have you done to get past error 12? 

Error 43 is often power/hardware or driver.

@eightarmedpet I've encountered error 43 lately with different AMD eGPUs in Boot Camp too. In some instances the eGPU would be working at first then all of a sudden Windows would yellow-bang the eGPU claiming the drivers have issues. It's hard to determine whether it's Windows or Radeon drivers are acting up.

Super odd. Is it always Navi cards? I never had any issues with Polaris or Vega.

@eightarmedpet Error 43 happened on an RX 580 for me a couple of times. I did try switching to macOS right after to observe whether it's possibly a hardware issue. Interestingly enough the Thunderbolt connection was not detected in macOS. I had to disconnect and reconnect a few times for it be detected and the eGPU started working again. This was a VisionTek mini eGFX + RX 580. There were mouse and keyboard as well as Ethernet connected. None worked so it wasn't the RX 580 hardware issue. Maybe it's from the Thunderbolt 3 controller on either the enclosure or laptop? Thunderbolt 3 cable was the standard issued .5m one.

@jendrik_reis and which drivers have you installed? You may need to use DDU to clean up any old/corrupt AMD drivers and instal some nice clean fresh ones.

@itsage that only makes it a bigger mystery... is this something you've found recently or has it happened over the last few years? I'm kinda nervous about switching anything out in my system now as (tempts fate) everything has settled back down and is relatively stable.

ive installed bootcampdrivers, still error 43, then uninstalled the drivers with DDU, and then installed the AMD Drivers from the homepage. nothing changed.

repeated this steps but with no effect

@eightarmedpet This error 43/Thunderbolt connection issue is something I only experienced in the last couple of weeks. I'm testing this 2017 13" MacBook Pro with a different eGPU [ASUS XG Station Pro + RX 5700] now to see whether it's the laptop's Thunderbolt 3 controller/port causing the detection issue.

@jendrik_reis If the card works in macOS then it's not a hardware issue. RX 5700/XT drivers are not very good for external graphics use atm so it's hard to determine the right fix in Windows.

in MacOS the rx 5700 xt gets detected correctly and runs flawless.

 

dont know if waiting for the error to get fixed ( new drivers, win update etc. ) or buying a other AMD Card ( Vega 64.. )
