SKT energy MSR reads on Atom C2750

Hi all,

I got a new server with an Atom C2750 (Avoton) an I was looking at the performance counters with pcm.x (IntelPerformanceCounterMonitor version 2.6, which should support this chip).

Most of the data seems OK, but the read for consumed energy seems wrong, as I see a roughly constant ~7.81 Joules consumption when running the tool every one second.

The read is proportional to the sampling frequency, so if I run

$ ./pcm.x 2

I always get ~15.6 Joules, regardless of the actual CPU load.

Is there anyone with the same hardware that can properly read the energy counter?
