Where does it output that to?

Once you run that, the output will in the Terminal itself. Just export it as a Text and attach here. Also, attach the updated EFI, excluding theme.

Okay great. Have that all done now. Really hope you are able to spot something I may have missed in this.

Here are the issues.

- Disable the Delete CpuPm and Delete Cpu0Ist as that's not required.
- If you're not utilizing the IGPU, better to disable it from BIOS and delete the IGPU Device entry.

Once done, provide the new set of PR files to check further. Don't forget to check CPU states and clock speed.

Okay,

- Disabled "Delete CpuPm" and "Delete Cpu0Ist"
- Disabled iGPU from the bios and deleted the entry (faster boot time with this done)

Still not getting correct speed. Stuck at 3.7GHZ.

If I manually change the iMac description to "5.7GHZ I get that speed when it first boots for maybe 5secs then it clocks back. It is not a temp issue too as it runs perfect in windows

Updated files attached.

Provide your BIOS Settings and check with iMacPro1,1 SMBIOS.

Okay I’ve noticed something strange when I change the symbiosis it does not change under “about this mac” but does change under system report. Is that normal?

Probably, that's the cause of conflict. What tool are you using to set the SMBIOS?

 

[Cliff8410]

I am using GenSMBIOS-master.

I have tries a few and can get the Smbios name to change in "about this Mac" but still states at 3.7GHZ.

I have attached the config that gets the full 5.2ghz but with this I cannot get a serial to work.

Just says "default string"

Is there any workaround for this?
