I have successfully installed Big Sur on a Latitude 5490, almost everything works fine.

I noticed that when I turn it on for first time, the DRAM value is always higher than 1, if I restart these values when idle drop to values lower than 1.

Someone has any clue of what can be happening?

IOReg
EFI

Thanks

EFI link is having error.

CPU PM seems to be enabled. Voltages are controlled via BIOS and ACPI. The memory voltages should range between 1-1.5v and that's completely normal.

Sorry for EFI link, google has marked as malicious.

Here is a new one EFI.

Configuration is not as per the guide but is good. Try to disable OC Work SSDT and then check. However, as mentioned previously, you don't need to worry as it's normal.
