AMD Radeon Navi GPU

[Hackintoshron]

Hi guys i know its an old thread but i have simular issue on wat seems to be fully working rig , it freezes about 15 minutes in to bench marking , no oc , runs cool , otherwise works fine .

You'll need to give some info about your OS, boot loader, attached peripherals, benchmarking software, what point in the benchmark is the freeze occuring, and possibly more to get an answer, but I would suggest you go on over to this thread and post your question: https://www.tonymacx86.com/threads/...700k-amd-rx-580.267551/page-2884#post-2216285.
I have the same motherboard as you and same processor but different GPU and I never get freezes. If you are using radeon boost or the like, you may want to disable it temporarily. Something in your EFI is probably off or in your OS but need more info to try to narrow it down. Hopefully, it's not a hardware issue.

I've installed Big Sur on my 6800xt without issues. But you wont have acceleration.

It's a good start... what you have to set to work?

I just used someones opencore repo for my motherboard without anything speciall for RX 6000. GPU worked as it was.

The GPU Work but without hardware acceleration. If someone set the pci-id to 5700xt...can we use with hardware acceleration?

does it means all the displays rendering is done by the CPU ?
If so, is it better to put a cheap GT710 instead ? while there no hardware acceleration with RX 6800?

This is my gpu :

I try to load the kext of 5700 with a gpu-spoof-id.aml whit this code:

DefinitionBlock ("", "SSDT", 2, "DRTNIA", "AMDGPU", 0x00001000)
{
External (_SB_.PCI0, DeviceObj)
External (_SB_.PCI0.GPP8, DeviceObj)

Scope (\_SB_.PCI0.GPP8)
{
if (_OSI ("Darwin"))
{
Method (_DSM, 4, NotSerialized) // _DSM: Device-Specific Method
{
Local0 = Package (0x04)
{
// Where we shove our FakeID
"device-id",
Buffer (0x04)
{
0x1F, 0x73, 0x00, 0x00
},

// Changing the name of the GPU reported, mainly cosmetic
"model",
Buffer ()
{
"AMD Radeon RX6900XT"
}
}
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}
}
}
Scope (\_SB.PCI0)
{
Method (DTGP, 5, NotSerialized)
{
If (LEqual (Arg0, ToUUID ("a0b5b7c6-1318-441c-b0c9-fe695eaf949b")))
{
If (LEqual (Arg1, One))
{
If (LEqual (Arg2, Zero))
{
Store (Buffer (One)
{
0x03
}, Arg4)
Return (One)
}

If (LEqual (Arg2, One))
{
Return (One)
}
}
}

Store (Buffer (One)
{
0x00
}, Arg4)
Return (Zero)
}

}

}

Why my spoof doesn't work? I think is not loaded, becouse if I have an error with the drive I have a kernel panic... even I can log into my system with the 14mb gpu...

No it runs on VESA drivers or default non-accelerated drivers. It is the same as using Intel IGPU that is not set up correctly or is not supported.

I didn't know that
