Hi @Draft any luck?

I found a good deal for 6700 xt, but I am still in doubts if I should go for it and sacrifice, forgrt about ryzentosh or get a compatible one.
Not for now !
It is better to buy a compatible GPU.
6900 xt have a good prices now

Hello, I have my 6600xt working on Monterey
Since I just swapped 5700 for this, my hackintosh hibernation doesn't work but sleep, which it goes black screen after wake from hibernation
Sleep and hibernation works like a charm when using 5700
Anyone who knows the idea? Appreciate it a lot!

Here's my thing:
OC 8.4
Smbios: MacPro7,1
Boot-arg: agdpmod=pikera
HibernateMode=NVRAM
With whatevergreen and hibernationfixup kext enabled

Okay. Try adding this line to your RX6600XT device properties:

key: CFG,CFG_USE_AGDC
value: 00
type: DATA

Try removing agdpmod=pikera from the boot-arg and see if that helps. And don't forget to use ResetNVRAM or Shutdown before reloading the updated EFI.

I tried that once before, but still failed
With WEG enabled and boot-arg: agdpmod=pikera or agdpmod=ignore --> wake from sleep (good), wake from hibernation (goes black screen)
Without WEG and boot-arg: agdpmod=pikera or agdpmod=ignore --> wake from sleep (good), wake from hibernation (goes black screen)

Actually, i am thinking if that really just goes black screen (graphic card issue), but crashes system (as i notice network activity stops such as spotify remote control after wakes from hibernation)
:crazy:

I have bought an ASRock RX 6600 XT card as well and have kind of the same experience with it does sleep but wake with a black screen and a kernel panic. That has not happened with mu RX 590 which I use for years now. It seems that the card is sleeping better than the Mac, as in the kernel panic file it's stated as cannot find GPU. I'm using Boot args: agdpmod=pikera and SMBIOS iMac20,2.

macOSPanicString":"panic(cpu 0 caller 0xffffff7faad0c9ff): \"[3:0:0] GPU Not Found! PCI Config Access Fails!!!\n\" @AmdRadeonController.cpp:1998\nPanicked task 0xffffff954ea43670

May be someone can shed some light on this?

Try using MacPro7,1 as smbios?
My situation works well with wake from sleep but no luck with wake from hibernation

If the 5700 XT was working for you and sleep hibernation worked fine with it. Do you change anything since then ? can you back track any changes or steps u took when u got ur 5700 XT ? Maybe with the 6600 XT you have to undo changes you may or may not have made since getting your 5700 XT ? Please keep us informed !
