Hello there !
Im new to the site, third message, and got last week an eGPU with a Vega 56.
I managed to do some decent undervolt profiles in Wattman and they are running stable in Windows.

I'd like to do the same in macOS but I really dont know if this is possible and how. I'm running it in a Macbook Pro 2017.

Thanks in advance.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Hello? Someone ? Nobody ever answers me, not even to buy or sell...

@ezequielfriscia I believe I may have answered on another thread about the same. You can refer to this build thread for more information. Same mechanisms mentioned there would apply to the Vega 56 (56/64 are essentially have very minor differences). Hope that helps.

In many cases people don't answer posts as they may not know the answer. With this topic that might often be the case. I also suggest using the forum search function and search with keywords. It's a little bit more effort but I have had satisfactory results in most cases.

Yes sir, I did a search before and I found this message:

@donluca Haven't had time to investigate it, and it seemingly relies on retrieving a soft power play table from the Windows registry first (which I'd want to remove as a dependency). Details:  https://www.insanelymac.com/forum/topic/325120-vega-frontier-edition-on-high-sierra/?page=6

In the above link, I'm not sure if modifying the controller is needed (could override with codeless kext). Anyway, patience is all I can offer at this time ;p

Meanwhile you can try the method mentioned at that link.

But I really have no idea how to continue or doing it.
Tried to sign-up to Insanelymac but the form / validation email doesnt work at all.

That is a different question. The process involves editing system files (specifically AMD10000Controller). Just dig through the insanelymac page and you should be able to find what to add/edit. Once the edits are complete, you will need to invalidate/rebuild the kernel cache, which can be done using some commands (see Command Line Swiss Knife in my signature) or using an application like Kext Utility. SIP will have to be disabled.
