Hello everyone,

Thank you for these many ressources, I would like to ask you for confirmation before upgrading my eGPU setup please.

 

So far I have happily enjoyed this setup thanks to the informations provided in the community:

MacBook Pro (Retina, 13-inch, Early 2015)

MacOS 10.12.6 Sierra

Sonnet Breakaway 550

Nvidia GTX Titan X (Maxwell)

I installed using the automate-eGPU script and connect through a thunderbolt 3->2 adapter. (it needs timed plug after entering password when starting my mbp).

The card and enclosure belong to my laboratory, I am now investing in my own setup which I wish to get working similarly.

 

I would buy a more compact Razer Core V2 and a more powerful Nvidia GTX 1080TI (Pascal). I read on the automate-eGPU page that Pascal cards should be supported. Can this setup work then ? And about the new installation, how shall I proceed ? Should I run the uninstall command and start from scratch a new installation ? Or would it be possible to run an update (I probably need new nvidia drivers) ?

 

Last thing, if I may take a 2080ti instead, would it be possible to use a Turing card too ?

 

Thanks in advance.

Best

Adrien

@adrien_chatton Nvidia never released macOS drivers for Turing cards so you won’t be able to use RTX 2080 Ti. GTX 1080 Ti would work as long as you don’t run newer version than macOS 10.13.6. Apple Thunderbolt USB-C/Thunderbolt 3 to Thunderbolt adapter and automate-eGPU script remain the prerequisite to make the setup work.

Thank you for your clarification ! I will go for a 1080ti then.

When I get the new eGPU box and Pascal card, I plug and run again the automate-eGPU ? Can it update or should I first uninstall ? (best actually would be to have both the previous GTX Titan X and the new 1080ti to work, not sure if that is possible ..)

@adrien_chatton I’d personally would recommend using @Mac_editor‘s purge-wrangler script in 10.13.6. Multiple Nvidia eGPUs may work but it’s not as straight forward. You may have to try different connecting methods.

thank you for pointing this out, the purge wrangler seems great as it is still actively developed !

I am still on Sierra, 10.12.6 ; right now I don't need to upgrade my OS but I might and it's good that purge wrangler has made it to 10.15 already.

I could start using it anyway, so when I get the new eGPU, I have to run the automate-egpu uninstall command and then do the installation with purge wrangler, is that what you would recommend me to please ?

@itsage   Coming back for a little update and asking an other advice if you can recommend please 🙂

I got a Razer Core Chroma and a RTX 2080TI ! With in mind to do a dual boot anyway on my macbook so I am no more bothered with limitations from Apple and issues for any OSX update.

 

If I may ask, should I go for Windows 10 or 7 ?

I suspect GPU compatibility may be better for Windows 10 and might go for that but I first double check if this is right.

Regarding taste, I never used any of them and will stick to some programming and using few specific softwares (MaxMsp/Ableton) so I dont think it will change so much. The common other things I will continue doing with the mac OS.

 

Thanks !

@adrien_chatton I would recommend Windows 10. Particularly Win10 1809 to be safe because 1903 can be trouble on many systems regarding error 12. Hopeful your RTX 2080 Ti will work without issues because Nvidia eGPUs typically have an easier time in Boot Camp.

@itsage  Thank you for the recommendation, I will get windows 10 and try to be on 1809 for the bootcamp.

I noted about the error 12, there is a reference on the forum, hopefully all work fine without too much hassle or I can try these fixes. Anyway, I need to bootcamp and I feel it's better to leave it to windows for the eGPU since apple lacks so much support.
