Thunderbolt 3 Cable Connection Pretty Loose/Wobbly on eGPU Boxes
Does anyone else have this same issue and can help out?
First, my Setup:
- MacBook Pro 2016
- Sonnet Breakaway Box 550W
- AMD Radeon RX 56
- Choetech 2m 40Gbps active Thunderbolt 3 cable
- Both macOS and Windows Bootcamp usage
From time to time the eGPU seems to disconnect from the OS, both on macOS and Windows 10. During games on windows this would crash the game of course, whereas under macOS non-game usage the system notifies me that the GPU was disconnected without proper ejection.
I realized that the TB3 connection on the eGPU side sits pretty loose. What I mean by that is that compared to the MacBook side, where the cable end is 100% inserted in the MacBook chassis, on the eGPU Box the connected cable end sticks out quite a bit. As a result it can be bend pretty much upward and downward while being connected.
That is when I realized when I bend it a bit the connection breaks up. I can reproduce this any time.
I even tried this with the very short cable that comes with the eGPU box.
So I sent the box in to Sonnet after their support told me that this shouldn't be the case.
In the meantime I purchased a Razer Core X to play around and see if it works better for me. But here comes the weirdness. It behaves exactly the same way as the Sonnet Box.
I think the fact that the cables don't get inserted 100% is pretty bad in terms of connection stability as the wobble factor is too high.
Anyone else experienced the same thing?
I've had the same problem on my Razer Core X, but also on the TB3 ports on my 9575. Ended up just adding a thin layer of super glue on the connector to make it fit more snug in the connector and has been working fine. Was having random TB3 disconnects if I moved the laptop before which sometimes caused pretty bad crashes.
Just an update for anyone who might have similiar problems: The signal disruptions seems to have been caused by the 2m active TB3 cable I was using by Choetech. I approached their customer service and they didn't even hesitate to send me a new one without even requiring the old one back. So either they are very customer-friendly or they know that their cables cause problems sometimes.
I've had this problem with the Mantiz Venus. If the cable is touched even slightly, it disconnects and my PC crashes.
I emailed Mantiz - they say the cable has over 30 pins, just don't touch it.
Different cables didn't help.
I'm necroing this thread because I've had the same issue intermittently for more than a year (Dell XPS 9550, Mantiz Venus, Cable Matters 2m). Have any of you found an alternate cable that doesn't disconnect if you look at it wrong?
