I've reached out to Asus with a full report and a link to this thread. However I doubt they'll look into it, as the sTRX40 platform is discontinue= d. I'm not export on ACPI tables at all, but I'm wondering whether it's the mainboard vendor to blame for this. I believe the "AGESA" firmware which is part of the bios is responsible for setting up CPPC. And this firmware is provided by AMD to the mainboard vendors. For sTRX40 (which only lasted one generation), the latest version seems to = be 1.0.0.4. Perhaps this version is too old and doesn't provide the necessary info/specification for the ACPI tables. --=20 You may reply to this email to add a comment.
