MacbookPro crashes shortly after connecting eGPU
I've been trying to get my new eGPU working with my Macbook Pro for a while now without any success.
The short version is that the MBP crashes a couple of minutes after connecting the eGPU. Sometimes it just locks up, other times it reboots. The time varies depending upon which monitors are connected - 24" can last 5 mins, 35" ultrawide 2 mins, both at once doesn't even display the wallpaper on the external screens before dying.
I am strongly of the opinion that the Razer Core Chroma is faulty. However, after returning it to Razer they have just sent it back saying no fault found.
For what its worth, I've tested with a friends 13" 2018 MBP, also running 10.15.2, tried 2 different thunderbolt 3 cables and two different GPU, although both are identical Gigabyte 8GB RX580s.
I still have the same problem though and I'm open to ideas before I get into an argument with them!
Assume you are using a standard (short) TB3 cable?
Does your Gigabyte RX580 have a BIOS switch?
There are reports of frequent crashing with Gigabyte RX580 cards.
Some Windows users say they have to download MSI Afterburner to reset the RX580 fan curve to ramp up early to 100%.
Since you’re running Catalina, I would test for a day swapping out the RX580 for an RX5500 XT (assuming you live near Best Buy or Microcenter).
Thanks for the suggestions.
I've been using a 6ft Startech TB 3 cable as well as the 2ft (I think) that came with the Razer. The longer cable is supposedly Thunderbolt certified. Either way I see the same problems though.
The RX580 doesn't have bios switch. I flashed it with the latest official Gigabyte bios before I started as I wasn't sure what the friend who gave it to me had done with it previously.
The fan speed is an interesting point though. I hadn't noticed if the fans on the card were spinning at all as it was facing the other way. The quicker failure with the more pixels being driven does point at card over-heating although it does go very quickly.
Unfortunatly I left my MBP in the office today so I will have to check that tomorrow!
I'm in the UK so no Best Buy or Microcenter. There is always amazon though...
