Added Sapphire RX 5500 XT -> Random freezes and reboots

Recommended Posts

HI there,

New poster on this forum🙂

I have an issue with my hack since adding a Sapphire RX 5500 XT to my hack where the system will sometime freeze and reboot out of the blue, it also happen most of the time when waking the hack from sleep. I didn't have an issue when I was using the iGPU (UHD 630). I have no idea what could be the cause and I hope someone can help me fix it.

My specs

Monterey 12.1 - OC 0.7.7 - iMac 20,2

ASROCK Z490 Phantom Gaming ITX/TB3

I9 10850K / UHD 630

Sapphire RX 5500 XT

I'm using SSDTs extracted from my DSDT (generated under windows) except for USBX.aml which I got from the OC install guide

Let me know if there is anything else I could provide to help and I' happily do so.

Thanks!

Ok I'll try and report back

I've installed the EFI for Comet Lake, removed unused kexts and added my USBports.kext

Also edited the plist replacing iMacPro1,1 by iMac20,2 and added board id, serial, MLB, ROM and UUID (couldn't find Smcplatform value so left the one that was there) 

Now that I've done all this, what can I provide you with to check that everything is properly configured?

Thanks!
