Crash! (AKITIO Thunder2 + RX480)
I'm new. Hi!
I purchased an AKITIO Thunder 2 from a user, already modified with an external DELL 220W power supply.
Inside it features an 8GB AMD Radeon RX 480. I have a Mac Mini Late 2012 i5 2.5GHz 16GB RAM (TB2).
Everything works properly.
After a few minutes of use, or during the benchmark, the monitor turns off and the Mac crashes.
Are you using a 4K display @ 60Hz over HDMI by some chance?
No, I only connected an ultra-wide monitor (2560x1080) in HDMI.
Tested with 2 different Macs (Mac Mini late 2012 + MacBook Air Early 2014).
The monitor works perfectly, I am now connected with Sonnet 350 + RX 480.
can you locate the crash report? Have you tried running the setup with the eGPU case completely open/ exposed? The GPU could be overheating.
Could it be because of that issue where the reference rx480's draw too much power from the PCIe slot? I know they fixed it on the driver side for windows but not sure what happens when you have a setup over multiple pci bridges and with TB2
2018 Mac mini I7 - Sonnet BB550W + Gigabyte RX570 4GB - Alpine Ridge AIC – (TB3 to TB adapter) – Apple Thunderbolt Display
2019 15" MBP i9 also works as expected in above setup
2012 15" rMBP works with purge-wrangler
All on 10.14.6 (18G84/b) for debug kernel...
iMac14,2, no Built-in LCD, GT 755M dGPU - Bricked after Catalina DP update tried to flash nonexistent T2 chip. Mucking around with Pomona clip, looking for BootROM dump if anyone has one 🙁
I have had that problem before. I really couldn't fix it other than stepping down to a low profile RX 560 4GB from MSI. The performance is actually not bad at all you will be surprised. I'm using it with a MacBook Air 13.3" 2012. If you found a solution to the problem please post. Thank you.
