Is that a dual-socket machine?
Because I have only the fam15h_power-pci-00c4 adapter. And mine goes
between 20W and 40W in idle.

Or is that an MCM box? I.e., a Multi-node CPU? Because:
Documentation/hwmon/fam15h_power:
"On multi-node processors the calculated value is for the entire package
and not for a single node. Thus the driver creates sysfs attributes only
for internal node0 of a multi-node processor."
And I remember Andreas did that should_load_on_this_node() thing.
If so, then 105W vs 167W should fit.

That's Trinity. That PCI device ID is not even in the kernel - I'm
guessing no one has even thought of enabling fam15_power on it. I don't
know even whether it supports the different PCI interfaces like TDP, TDP
limit, etc.
IOW, something like that might not really help.
Rui, you could take a look if you feel bored and if you have a TN system
somewhere lying around.
