Thank you @CaseySJ and @Feartech !

If you're having problems installing macOS on an AMD Ryzen system, simply create a post in Installation --> Big Sur Desktop Support and reference my username.

Someone in this or the Z390 Designare thread managed to convert MBR to EFI. Will look for that post shortly.

Thanks, I appreciate everybody help.

I have followed the steps and now its shows Radeon RX 5500 XT, but still the temperature are not show.

I am using OC

Please post a screenshot of the HWMonitorSMC "Settings" window. It's possible that GPU monitoring is disabled there.

Update:

Please take these steps:

• In the Settings panel, uncheck "Use the IOKit monitoring for GPUs"
• Then exit the app by clicking the x as shown in screenshot 2.
• Then launch HWMonitorSMC2 again.
• In the Settings panel, check-on "Use the IOKit monitoring for GPUs"
• Then exit the app by clicking the x.
• Then launch HWMonitorSMC2 again.
• Now GPU monitoring data should appear...

I got a Blackmagic UltraStudio Recorder 3G. The first time I connected it I was able to capture a video recording. The companion software recognizes the device, and I can switch between SDI and HDMI. Every subsequent attempt at using it since then fails. The Blackmagic software continues to detect the device, and I can switch between SDI and HDMI. But no video stream appears in anything I try. It worked once and only once. I have tried booting with it connected and not connected. I have yet to revert to the F5 BIOS, and I have made no attempt to flash the TB chip. The Blackmagic app says it's capturing at 1080p 29.97. I was able to capture on the same box on Windows 10 using the same software, but Windows is having very annoying audio issues. And I hate to have to boot Windows every time I need a video capture. I'm on 10.15.7.

Please try replacing SSDT-GPRW.aml with the attached version, thanks to a good observation by @canyondust. Then see if Windows will boot through OpenCore when GPRW is enabled (both the SSDT and the Patch).

Unfortunately it did not work. Same problem. I have enabled the new SSDT, the patch, rebooted macos just to make sure that I could boot and sleep. no issue on the macos side. Then rebooted, picked up windows 10 from OC picker and reboot after a few seconds with the same acpi bios error.

Some questions:

• Which version of OpenCore are you running?
• If it worked once then no need to flash Thunderbolt firmware. Instead, it may be necessary to enable AppleVTD, which also requires enabling VT-d in BIOS. OpenCore 0.7.2 and newer supports AppleVTD.

There’s a second version of the SSDT in @canyondust’s reply a couple pages back. We should give that a try next.

Here is a link to a procedure for converting MBR to GPT, but it requires booting into Windows.

How to convert MBR to GPT drive to switch BIOS to UEFI on Windows 10

A PC with UEFI is more secure and faster than the legacy one using BIOS, and here's how to switch.

www.windowscentral.com

Have you tried a cold start (power down, flip PSU power switch to OFF for 10 seconds, then power back up)? If so, does Windows appear as a boot option in the BIOS Boot Menu (press F12 at Gigabyte splash screen)?

I’m not sure that second one will work without modifying the ACPI patch to only rename the function declaration and not references to it, and it was made from my DSDT which is Vision G bios F20. Also I should double check if SS1-SS4 are indeed IntObjs

And further: I'm returning from the method early, so I doubt the 2nd SSDT would work at all, period.
