Akito Thunder2 Resetting Whole Macbook Under Load

So I have successfully been using my Akito Thunder2 (loaded with MSI AMD 560 OC) with my MBP late 2013 with purge-wrangler and purge-nvda (to disable the internal 750m). Today I started up my machine and launched Final Cut Pro X to get some work done, and the entire system locked up. The external screen was plugged into the eGPU. The fans went really fast on the Akito and the system rebooted a couple of times. This keeps happening.

My first thought was that it was a software bug, then I tried a different TB cable, and now I suspect the 9.5A power brick, or some other power-related problem (maybe the PCB in the enclosure is fried?) may be making it lock up. 

I would really like for it to not be a problem with the card itself, but does anyone have a similar story and figured out what the problem was?

Much appreciated.

Have you tried some other apps to ensure that the issue is with GPU load in general? I suggest running a benchmark to see exactly what happens. If your system is crashing, on next boot, you should see panic logs. Please share those. You can share additional logs from purge-wrangler as well (more options menu).

OK so this is weird. There is no log of the KP in the Console, I even googled precisely where to find it to be sure. When I reboot the Mac without the eGPU plugged in, it starts fine, but there is no dialog saying "your computer was shut down improperly" or whatever. Also, the multilingual Kernel Panic screen doesn't appear. before it glitches and reboots.

I have a Mac mini with thunderbolt which I use as a server. I used purge-wrangler to prepare it for the eGPU, and tried launching FCPX, and Obduction (in Steam), both apps which use a lot of eGPU horsepower. It crashed the computer and rebooted the same as my Macbook, so the problem is definitely on the enclosure side.  I'll look through the logs again.

Is it possible that because I have the OC version of the card, it is drawing too much power and fried the unit? 

Next is to try the 560 OC in a traditional PC and see if it is working fine I guess.

Let us know how this goes.

Hello. I had exactly the same problem with Gigabyte Rx 560 OC 4GB in Thunder2 box. Under MacOS was everything ok. But I mostly played games (Diablo3, Metro redux, and some benchmarks). Under BootCamp W10 it was crushing spontaneously. Last time when I played Bioshock the box was stopped and I sensed smell from burden. I fried a transistor FDC610PZ. Now I’m waiting for this component from Germany. I hope I will able to fix it. So be careful because this card is obviously draw more watts from PCIe port as 75w in some applications.

@branislav_benak This is good to know, I’m pretty sure mine is the same problem, or will be soon. Out of curiosity, if you fix it, what will you do to prevent it happening again? Will you add another PSU and use a card which takes extra power connections?

@goalque Thank you for linking to the info. I’m busy during the week but once I get a chance I will figure this all out and report back.

This is good question. I'm not decided yet. I ordered 6 pcs of this transistors. I will replace one and try with the RX560. If it will still crushing in BootCamp, I'll try the goalques bypass. If the crushing after bypass will not stop, I will return to using the GTX1050Ti. This card is not so demanding and I have good experience with it in MacOS also in BootCamp. But I will have to downgrade to HighSierra. I like this box because of its small construction.

Thanks for the info about the mod, I performed it on my Thunder2. Everything seems to work as before, but again when I put a load on the graphics card, even if I don't have a monitor connected, the computer seizes up and eventually it reboots or I have to reboot it. I'm starting to think that the graphics card may actually be the culprit, since I can't see any damage or problems with the Thunder2 PCB. I'm sending the card to a friend to try in his machine. If that answers the question then next job is to procure another GPU for the enclosure.

An update: I managed to acquire an NVIDIA 780 Ti and 500W PSU. I know this is a native card, so I wanted to see what would happen. I also reinstalled macOS from scratch, and then installed PurgeWrangler

macOS recognizes the GPU (which I am running headless for the moment), but putting any kind of a load on it crashes the system. This time, however, I'm getting the familiar Kernel Panic screen, and getting information in the logs. If you have any insight, I would really love to narrow down what could be wrong.

At this stage, chances are good I'm going to have to nab a new Thunder2 or equivalent. I've shipped my 560 OC to a friend and am still waiting to hear back, but it seems the problem is in the Thunder2.

 

Looking forward to any insight.

Could be an issue with the Thunder2 as you surmise, given that you eliminated all other variables already.
