FricoRico Posted August 20, 2016 Share Posted August 20, 2016 I wonder if this also works under Windows. But this is great news for my AMD based eGPU plans! I hope it will also play nicely if a laptop is already equipped with the AMD M370X, I don't want it on the internal screen, but would love to power the external screen with an AMD RX480.

Possible with the help of my EFI app, not fully automated yet Quote Link to comment Share on other sites More sharing options...
FricoRico Posted August 27, 2016 Share Posted August 27, 2016 (edited) I went the same route and bought my first eGPU today based on the XFX AMD RX 480 XXX OC edition. Putting it together as I'm writing this. Hoping for an easy install! What is this 'EFI app' you are talking about?

euqlaog Posted August 27, 2016 Share Posted August 27, 2016 automate-eGPU EFI. I’m not sure if you’re able to achieve the same with the Thunder2 & demo app. You may have better luck with an iGPU only, pre-2015 MBP. Quote Link to comment Share on other sites More sharing options...
FricoRico Posted August 27, 2016 Share Posted August 27, 2016 It seems that your script is capable of finding the eGPU and it also adds the identifier to the AMDRadeonX4000.kext. Somehow Mac doesn't load this kext though, as it sees it as an 'display' device: Quote Link to comment Share on other sites More sharing options...
FricoRico Posted August 27, 2016 Share Posted August 27, 2016 @goalqueUsing your efi bootloader to disable the dGPU and enabling warm-boot enables me to load Windows whilst detecting the RX 480. Sadly Windows somehow reports the device to have 'too little resources'. Any clue what it might mean by that? Quote Link to comment Share on other sites More sharing options...
euqlaog Posted August 28, 2016 Share Posted August 28, 2016 Yes, these are known issues. The EFI demo works with an Nvidia card. AMD7000Controller.kext conflicts with the eGPU’s AMD9500Controller.kext and therefore the latter refuses to load. You can check this by kextstat command. There is a partial workaround: Quote Link to comment Share on other sites More sharing options...

There is a partial workaround: That is somewhat great news! Where can I find out more about this workaround? Bu the way, I thought that the RX480 used AMDRadeonX4000.kext? Does it need both the AMDRadeonX4000.kext and the AMD9500Controller.kext?

Both kexts are needed. 3 hours ago, FricoRico said: Yesterday night I tried fixing the error by following this guide. I was unsuccessful but hopefully I can make another attempt that fixes it. Try manually disabling and uninstalling the Iris Pro in device manager, then keep looping with warm-boot & disable dGPU options, with an eGPU monitor plugged in. Hold down the Option key between restarts and choose “EFI Boot”, it may work. The problem is that my app tries to keep Iris Pro enabled, but you can’t install the latest drivers from AMD if the iGPU is also active. I’m not sure how well the RX 480 is supported by Windows 10 built-in drivers. If you want the internal screen as well, you can try DSDT override approach as @Tech Inferno Fan suggested.

Aww it's really a shame you can't reveal that. Why can't you reveal it? Might I be so bold to ask you for it through a PM? Quote Link to comment Share on other sites More sharing options...

FricoRico Posted October 2, 2016 Share Posted October 2, 2016 @Tech Inferno Fan For how long did you run this setup? I'm wondering about the heat dissipation for your setup. To me it seems like it would overheat quite easily running no fans and having no cooling for the memory pads. Did you really stresstest the card without the stock fan attached?
