Gigabyte B550 AORUS PRO AC Bios Settings / DDR Speichersteckplatz Problem

Hi

which OS are you trying to install?

Edit

If you like use this EFI

It should work for your system till Ventura OSX

if it boots we have to add ethernet kext for your motherboard

So you have Gigabyte or MSI B550 motherboard?

This is a debug Opencore version

post log and if it hangs a photo where it hangs

on bios

Serial port (if you have it) Off

CSM off

4G on

UEFI on

Resizebar Disable

Morning,

thanks for your help. I'm installed the big sure os. The Efi don't work and have some errors on the log. So i think it's the bios settings.

here could explain better? What do you see on the screen?

always a cursor?

Have you a working EFI with your Gigabyte for older OSX system?

Are you installing from an USB pen?

have you an EFI partition and inside this partition a folder called EFI with two subfolder Boot and OC?

if you have in this way and if you want to try again try this

If it hangs a phot please (if it is different from a flashing cursor)

I assume you have a 5800xt and a 6900xt (CPU/GPU)

Load bios default settings

then Only

4Gon

CSM off

Uefi On

fastboot disabled

Legagy USB and Handoff Enabled you are trying to install Monterey from a full Installer, disconnect also your ethernet card till we can see icons boot loader menu

Ryzen CPU today is pretty simple to install

Those screen is with my latest EFI or from which one you posted as a link?

avus90 ich habe die EFI von denn Onkel_Mikke angepasst OpenCore 0.7.5 zu OpenCore 0.8.5 DEV DEBUG

Und erstmal das SMBIOS von MacPro7,1 zu iMacPro1,1 geändert.

Sollte es nicht starten log an uns

I'll probably look like crap what I will say , but if you use custom memory and latest restrictevents, you don't need to create the dimm modules map

For the 6900 xt the best SMBios is MacPro 7.1 (IMHO)

with it you can decide whether to boot arg pikera or not (along with whatevergreen) based on the outputs it sees from its board

Personally I don't use whatever green kext but it also works by using it with boot arg on the graphics card that has

however I hope it starts with that EFI the only doubt for me is if he has 4g On he should delete npci=0x3000 parameter or viceversa

The SMBIOs can still be changed ( Deepl )

I found this boot-args npci=0x3000 in your post #8 .

Post #10

You said that this on must be 4Gon

Then you should also adapt the EFI for it

OSX-Einsteiger

That boot arg was present in the old working EFI of other user with old bootloader

It is advisable to use 4g option in bios than that npci bootarg

And user should be arrive to bootloader menu also with both used

Ps no polemics for me

👍

You should not use a map of usb created for other user

Try disable usb kext (if you have it) and see if you see your keyboard and mouse (with usb cable)

If you use Bluetooth mouse/keyboard maybe you have to map properly your usb

Let see inside USBPort.kext in use:

original user mapped in this way based in his system use (ports used or BT)

Your is (could be ) different

For this reason you have no Mouse or keyboard avus90

Thanks, usb is now working. Great

you have to see if in your daily usage if you could have the need to map USB

I have no need of this..but your platform could have to work properly in some parts (USB or BT if connected to internal USB ports

Hallo avus90,

vielleicht hilft dir meine aktuelle EFI (Ventura ready) zum vergleichen.

Die FehlerMeldungen von OC liegen wohl an einer völlig falsch erstellten config.

Denke daran, dass du deinen Prozessor in den "kernelpatches" richtig angeben solltest.
