On my old X299 Prime Deluxe, I had mine in slot 5, and I had to re-do the AML for it. Then I moved it, and again I re-did the AML again. So you can move it around, but to get the best out of it, your TB AML should be adapted to the slot it's placed in. It might work without the AML correctly compiled for the designated slot, but you must have at least an X4 slot for it. It works in an X8 or x16 slot as well.
This was what I thought as well! I’ve already changed the TB.aml to my specific slot, have no TB-cable to try it out yet though. Will post here about the result later!

Thanks.

HI @engineer.sek, I have a very similar build with a 10920x and single 5700xt. I'm having issues booting installer w/ clover config in this post. Can you please share your EFI folder?

Hello folks, I have been reading your posts about Asus x299 for months and I'm still looking for an exhaustive guide on this argument. I guess it's not expected in all this Forum although I don't know why... at least a buyer's guide :)
Whoever has a good and kind heart could help me likely for a stable version of X299 with ASUS Sage 10, a compatible GPU and noiseless bundle. I don't have any company and I cannot afford such a big wallet flush from Apple. :)
Happy 2020 to all of you!

Hi! I'm wondering if anyone would be able to help me? I recently upgraded my system from a GTX 1080 Ti to a Radeon VII in order to update to Catalina. I've been able to get it updated to Mojave without issue, but it locks up during boot when trying to install Catalina. This includes both a fresh install as well as updating from Mojave. In case there's an issue with my profile, I'm on an ASUS Prime X299-Deluxe and an XFX Radeon VII. I also tried the open core EFI folder and the results were similar. Any assistance on this would be very much appreciated.
