What cable are you using? Thunderbolt can be picky about cables and not every USB-C cable can do Thunderbolt. If it’s the cable that came with the dock, then that’s probably fine and the problem is something else, but otherwise try grabbing a new cable that’s specifically Thunderbolt capable.
Or if you want it right now, Apple’s Thunderbolt cables are fine and widely available at Apple stores and Best Buy and such.
So, I also wasn’t convinced it wasn’t the cable either. However, I tried the TB3 cable that it came with, I also tried an apple one that we use with the Mac - to no avail.
I went to Currys and bought a USB4/TB4 cable to be absolutely sure, it now sees the card and works fine.
So, to anyone in the future that has this issue and reads this…it may just be you need a more capable cable for your GPU - don’t trust the one that the eGPU comes with. I got a Logik USB4 cable for £25.
I am sure that is the case Cristian, and is a bit of an idiosyncrasy with this particular system. (although looking on other forums people have had similar issues and then just received replacements from Razer). This eGPU in particular was working fine from the person I got it off, and they used the supplied cable from Razer.
But this is the situation at my end…problem is solved with a new USB4 cable on the Framework 12G. So anyone in the future, if you get into bother with your enclosure, this may be a solution for you. Also, it works a treat, great performance for gaming!
