MP 1,1-5,1 No chance to run OCLP with RX560 on Ventura

[marqus]

Hi there,

I have a MP 5.1 2010.
When I try to install Ventura or down to Big Sur, I won’t succeed using a powerless RX560 next to an HD5770.

I use open core 6. I have both cards connected to two screens via hdmi and dvi.
The installer runs through. There are config windows on RX560 screen. But the one last step I am obviously doing wrong. I never saw the desktop.

Years ago, I did the same with RX480 and it worked fine. I’m my guts I feel sth like the missing power connector on the card is the culprit. But idk.

Is there a simple way to know when to unplug the hd5770? Do I need it after all?

I am slightly disappointed and am doubting my brains.

Thx
Markus

This has nothing to do with powered or non-powered RX560.

Two things:

• You can't mix a non-METAL supported card and a METAL one with modern macOS releases, this stopped working correctly with Mojave, when Apple started to require METAL for the user interface. High Sierra is the most recent macOS release that this combo of non-METAL and METAL GPU still works.
• Second, with unsupported macOS releases, the hack to provide accelerated support for non-METAL GPUs completely remove the GPU drivers for METAL supported GPUs, so this will never work, the moment OCLP removes the AMD drivers, the RX 560 (or any other AMD officially supported GPU) stops working.

You have to make a choice.

Thx, so, the combo 5770 and RX could run the latest with Mojave?
Or not at all? Sorry not understood completely…

Like I wrote, High Sierra is the most recent macOS release that you can mix a RX 560 and a HD 5770 without any problems.

Ah ok, sorry, my mistake. I do not want to use the old 5770 at all. Just thought I have to install it for installation.

All I really want is Ventura or little older with rx560 running fine. That’s all. But without boot screen I am lost..

you do not need a bootscreen to install a system or opencore!

How to select “efi boot” without boot screen?

How to select “efi boot” without boot screen?

this is done with the bless command in the terminal of the recovery mode
(or with martins script)

Read his entire instructions (or watch his youtube videos)

HERE you go -- you want version 0.8.9 (bottom right)

Should you have any questions/issues after you've got it running -- ask in THAT thread that i've linked.
