Mid 2015 15-inch MacBook Pro eGPU Master Thread
No need of EFI trick, just de-install -> install amd drivers and use the eGPU-toggler with you own material ID (follow the instructions).
I works just fine, I can play Far Cry 5 in Ultra, 2K resolution on an external display.
I hope that it will work for you too
mhhhh, not for me! I had already done that all before.
Ok I just did it now again, still no success!
The eGPU-toggler did not help me. Maybe I did something wrong. I do not know, which is the right PCIE-Controller. I just choose the ID of that one over the eGPU. then run ... after a while toggler finished without any comment.
Ok I admit that I was a bit confused with the right Material ID to choose too. The first one is the root pcie port (something like 0D05, exactly like the one in the script). And the second one is the ID that you obtain when you right-click directly on "Vega 64" device. The multiple occurences of this port must be changed in the script.
Maybe didn't we pick the same drivers? :/
Well, today I tried it again. But it seems to me, that our Macs are different.
I had made some pictures. Do not wonder: it‘s a german windows version.
In Toggler, I changed the marked positions.
I hope that the selected points are the right ones!?
And here is my device manager:
I disabled and enabled all possible bridges.
Number 1,2,3 and 6 are only possible to deactivate. The rest is not possible.
And I tried these 4 in toggler too. Without success! 😞
I use the left Thunderbolt port on the left side.
Hi! Here are the ports i used:
And the script i used:
I'm pretty much sure that your adress number 1 must end in 0D05, it was the same for me than for the author of the script, and it is the number 8 in your picture i believe.
And what do you mean by "the rest is not possible to deactivate"?
And btw I use the thunderbolt port close to the USB port, it does not work with the other one...
@anonymousse, oh yes there is - after changing the thunderbolt-port - the above pcie bridge with 0d05.
Great! But I am not allowed to disable it. I do this as administrator - sure. And toggler just tells me that the device is not able to be disabled.
For a while I could see the card. But after a restart the system does not detect it anymore on right TB-port.
@anonymousse, so, I had made some changes. I had updated Windows to 1909 and changed the pci.sys.
Now I have the correct ID of the PCI Bridge. But I am not able to disable it.
so I am Right at the finish line. I just need to disable/enable the bridge.
But how? Toggler is not able to... 🧐
So last chance for me and maybe easiest way for most users, is to set the correct mm commands for different GPUs.
As far as I understood; these are best for Radeon VII:
And now I must change the first three lines of mm commands for getting my Vega 64 going. Unfortunately I do not know where I can get these data.
Is anybody able to help, please? 😩
