Failure to boot with RX 6600 - user error or incompatible GPU #38
Comments
what is device-id of this card? is it supported OOB? If so, try to add boot argument agdpmod=pikera. |
I understand RX6600 is supported from the Dortania guide So I should remove this: \VEN_1002&DEV_73FF&SUBSYS_E4471DA2&REV_C7\6&16822204&0&00000008 I've tried resetting the nvram as well. |
Yes, you should remove the AML file for sure as it is not needed for RX6600. |
No success as yet, I'll revert back to it in the morning. thx |
Update
On the classic Mac Pro forums, they suggest flashing the BIOS of this card. It was to be the next step if I did not manage to get it working. Glad this wasn't required. With Device ID = 73FF, where and how would that be entered into config.plist? Should I change this part of the config.plist do you think? |
Thanks for sharing this here! |
Apologies if this is the wrong forum to raise this problem.

I'm checking to see if this is user error or have a bought the wrong GPU.
I have had the OC 0.8.3 Preview for macOS Ventura Beta 3 working successfully on my Z590i VisionD, RX570 32GB for both 12.5 and Ventura Beta3 and maybe 4. With no changes to the config.plist, drivers or kexts.
Today I bought and attempted to use a new GPU Saphire Pulse RX 6600, instead of very reliable RX 570 and have not managed to get the system to boot.
I removed the SSDT-BR0-6900XT.aml - no luck kernal panic, see image
I attempted to revert to 0.7.8 with latest Lilu and Whatevergreen - the boot managed to go somewhat further but got stuck in a boot loop, after trying to load the OS for 20 seconds or so.
Booting into W10, everything works fine.
No changes to BIOS from RX570 to RX660
Open to suggestions or ideas to resolve. It might be something minor I've overlooked.
Thanks
