Random freezes, reboots and sleep not working after adding Graphic card

[EliteMacx86]

I will try disabling the quirks in a minute and seee if it works, just wanted to confirm if I need to enable CFG-Lock and VT-D in BIOS as I'm modifying the plist or leave them disabled?

Let's see how this goes first

My advice is to keep them Enabled in the config.plist, regardless of your BIOS Settings. It can be a pain during debugging, once you update or flash the BIOS

PS: the other entry in DeviceProperties is linked to the sound, if I remove it I need to add the proper alcid boot argument to keep the sound right?

Yes, correct. That's mostly required when using IGPU, mostly for Laptops. Or when you need to spoof your Device ID.

I've been able to boot with the quirks enabled I now need to see if it will freeze; the thing it's that it's totally random. It can happen while browsing the net, watching a video/movie and can sometimes freeze on its own; I'll report back.

I'll try sleep with the following pmset settings and see if the system wakes instead of it rebooting

Set the Sleep/Wake function to default in the System Preferences. Keep doing the activity and check for any freezing. Also, make sure to remove the preference files from Library/Preferences/System Configuration, except for com.apple.Boot.plist file.

Empty bin and build a kextcache. Restart and then monitor. Report

which command do I use in terminal to build a kextcache?

sudo kextcache -i/

Thanks! I restored default power settings in system preferences, trashed the system configuration files, rebuilt the cache and rebooted the hack. I'll report back

Perfect. There should be no such issues now.

Hack went to sleep but when trying to wake it with a mouse click it rebooted, so sleep is still bothering and I have disabled it again.

Will now see if the system freezes while under use

Off-topic.

Hi there,

actually sleep is not off topic as before adding the dGPU so only using UHD 630, The system had no freezes and sleep was working properly.

I went through the guide "how to create OC config.plist" and for Comet Lake it mentions that "Sleep/Wake function is broken on Comet Lake Desktops when using IGPU as a Graphics Device."; it's funny that I'm facing the opposite scenario where sleep worked with the iGPU only but stopped working after adding the dGPU so this is still something to address.

Going through the guide I changed the ACPI patches by deleting the ones that come bundled with the config.plist as I do not seem to need them and added Rename PEGP to GFX0.

I also added Rename HECI to IMEI and Rename MEI to IMEI as from the notes I don't understand if I need to use these together with Rename PEGP to GFX0 or not; could you tell me if I need to keep the IMEI patches or not? Thanks!

So far I'm happy to report that I have not experienced freezes since yesterday so that's awesome

Concerning sleep, I have tried adding SSDT-USBW.aml+USBWakeFixup.kext but the system still reboots instead of waking up when pressing the mouse key. I could try adding the "ACPI-wake-type" under DeviceProperties like so:

PciRoot(0x0)/Pci(0x14,0x0) : acpi-wake-type : <Data> : 01

But I'm not sure it's the proper way so I still need to work on this

So still some research to do on sleep but everything is definitely more stable after the tweaks you suggested

Thanks!
