Damnation Posted July 27, 2022 Share Posted July 27, 2022 @daniel_k Throttlestop did not help for this, my CPU is unsupported apparently. I think this ACPI0010 device is interfering with it in this case too. I can get you a screenshot of what I'm seeing if you want. @canonkong@daniel_k Do either of you have any systems with this ACPI0010 Device?

Damnation Posted July 27, 2022 Share Posted July 27, 2022 @daniel_k also, why are you getting angry at me and accuse me of faking my screenshot? when have I ever done that? I simply reported that an ACPI table mod that removed ACPI0010 resolved the issue. Link to comment Share on other sites More sharing options...
Damnation Posted July 27, 2022 Share Posted July 27, 2022 @daniel_k This is how my system is without the ACPI table mod https://ibb.co/d6nYN9z Those Unknown Devices are the CPUs - they have hardwareID ACPI\ACPI0007 which matches the ID shown in my CPU SSDT I'm not sure how else I can prove to you that I'm not lying to you, let me know if there is a way I can prove it to you.

canonkong Posted July 27, 2022 Share Posted July 27, 2022 (edited) @Damnation I can't find any systems with this ACPI0010 Device on my Gigabyte B550I AORUS PRO AX. Edited July 27, 2022 by canonkong Link to comment Share on other sites More sharing options...
Damnation Posted July 27, 2022 Share Posted July 27, 2022 (edited) @canonkong You most likely don't have it. It'll be called "ACPI Processor Container Device" on Win 10 and 11 and just "Generic Bus" on XP, and all your Processors will be grouped under it.

canonkong Posted July 27, 2022 Share Posted July 27, 2022 @Damnation After update the latest bios, I found ACPI\ACPI0010 which names Generic Bus in system device. Link to comment Share on other sites More sharing options...
Damnation Posted July 27, 2022 Share Posted July 27, 2022 @canonkong OK. Can you check to see if it is having any effect on how much power your CPU is using when booted into XP? Link to comment Share on other sites More sharing options...
canonkong Posted July 27, 2022 Share Posted July 27, 2022 (edited) I modified the CPU driver and install it. But only show one processor. Modify the *.inf file and add this line: %AmdPPM.DeviceDesc% = AmdPPM_Inst,ACPI\ACPI0010 Edited July 27, 2022 by canonkong Link to comment Share on other sites More sharing options...
Damnation Posted July 27, 2022 Share Posted July 27, 2022 @canonkong Sort "Devices by Connection" this should show any other Processors that also need a driver install. Link to comment Share on other sites More sharing options...
canonkong Posted July 27, 2022 Share Posted July 27, 2022 @Damnation I had tried it, but I can not find any other device need to install driver. Link to comment Share on other sites More sharing options...
Damnation Posted July 27, 2022 Share Posted July 27, 2022 @canonkong This might be a case of ACPI tables hiding devices from an older OS? I would need to check your ACPI tables to be sure. I don't know why they added this container to the ACPI spec, what was wrong with the old way of doing it? why the container? Link to comment Share on other sites More sharing options...
canonkong Posted July 28, 2022 Share Posted July 28, 2022 @Damnation Maybe AMI force to make this. Link to comment Share on other sites More sharing options...
Damnation Posted July 28, 2022 Share Posted July 28, 2022 @canonkong That seems to be the most plausible explanation. Link to comment Share on other sites More sharing options...
canonkong Posted July 28, 2022 Share Posted July 28, 2022 @Damnation And I don't think ACPI\ACPI0010 is Processors device. Testing on NTOS 6.2.7962 . Link to comment Share on other sites More sharing options...
Damnation Posted July 28, 2022 Share Posted July 28, 2022 @canonkong Just to be certain, can you do sort "Devices by Connection" and check whether or not if the Processors are grouped underneath the ACPI0010 device? Link to comment Share on other sites More sharing options...
