Big Sur 11.3 beta fail on Zenith II extreme

[fabiosun]

your thunderbolt has a patched firmware?

 

[ddk]

no I don't think so , can I patch it how ? but I tested it on windows error "Thunderbolt device functionality might be limited" no gpu detected but only usb 

[fabiosun]

in windows you have to add a proper driver for titan ridge

you can patch your Titan Ridge, but it is not simple

A patched card will work on OSX but it wont work anymore in windows

 

to patch

follow link i have posted before in this thread

you need some stuff (eprom programmer)

 

Gigabyte Titan Ridge on Proxmox/OSX baremetal (WIP) - General - MacOS86

[ddk]

is there another way without patch for OSX?

[fabiosun]

No (in my knowledge)

sorry

also Trx 40 designare board needs a patched firmware for OSX.

This motherboard has a firmware wich support Titan RIdge by default and you see with it thunderbolt menu on bios..

but without a patched firmware ..no joy in OSX

 

[ddk]

Thanks for your help appreciated .

you mean my trx40 bios need patch ? I can try that if possible how can I do that?.

I ordered Gigabyte GC-Titan Ridge Card and the programmer but according to ameyrupji Catalina 10.15.3 latest supported I'm afraid.

and the GC-Titan Ridge must be on PCIe slut 1 can't be on slut 3/4 for reasons .

No @ddk

titan ridge must be patched

not motherboard bios

And in my knowledge patched firmware for Titan ridge needs card to be inserted on slot 4

Hello @ddk,

 

sorry to tell you that, but I’ve downloaded and copied your efi folder directly to my USB with Big Sur 11.3 installer and it has worked properly for me...I didn’t change anything at all...just copy/paste...

 

I will send you some screenshots in a few minutes.

And here the fotos as promised.

 

Nvidia drivers are not working 100% (it shows no Metal) and processor is not at fully power, but it works with the same motherboard and CPU than yours.

 

Again, I just copied and paste, so maybe you should check your components I suppose...

 

I can share with you any other detail you require about MB config, NVME or any other.

Hello @Sakeador

Thanks for sharing your test.

The problem was I was using RX 6900 XT only to boot Big Sur 11.3 but it solved when I inserted supported GPU Radeon Pro WX 5100 along with RX 6900 .

It is weird that some Unsupported GPU can boot but others not.

@ddk

Apple removed vesa support for unsupported GPU (AMD).it is always possible to connect to your TRX40 via ssh or teamviewer if you want

..optimistic way to think is because they have separated old driver with new one we will have in future OSX version! 🙂

 

Pessimistic people say..no way..and apple will never deliver a proper driver for RDNA2

 

Strangely Nvidia has a minimal support also in RTX series GPU

but here optimistic and pessimistic people say no way apple produce a nvidia working driver support!

Finally Here we got it 11.4 Beta 1 has RDNA 2 drivers https://developer.apple.com/documentation/macos-release-notes/macos-big-sur-11_4-beta-release-notes
