SpeedStep worked good in ML, get stucked in high step in Mavericks

This is what shows MSRDumper:

10/27/13 5:26:08.000 PM kernel[0]: MSRDumper CoreMulti(12)

Looks like in a loop from 12 to 22

Your log says that it can reach 12 22 26 29 30, 12 on idle, 22 on normal, it can get turbo boost too.

I think it's normal.

I thought that my browser (Firefox) was hungry for CPU but I did the same test for PStates with Firefox opened and went fine (stable at 12 without doing anything alse). HWMonitor in Mavericks looks broken or having abnormal CPU usage.

HwMonitor has always been somewhat of a pig. Last I checked, it polls for new data far far too often. Not really appropriate to run at startup while on battery. I don't run it unless I need to look at something.

Is a pity not to have some monitoring to see if your CPU is not burning.
Thank you anyway RehabMan.

I think you'd know something was up with the fan running full speed + the heat under your left palm.

I use iStatMenu and no problem so far

nguyenmac thank you for the recommendation.
I think there is also something weird in Mavericks, most of the time is at PState 22 (normal) and rarely is at 12 (idle) even when doing nothing.
In Mountain Lion most of the time was at PState 12 even with VLC reproducing a movie or another task and HwMonitor was showing this.
Maybe HwMonitor could benefit from compiler optimizations for osx 10.9?

P.S.
Another problem that I have now is that I cannot see anymore in Console the output of MSRDumper.

10/27/13 11:24:20.436 PM com.apple.kextd[12]: kext com.flaked.kext.MSRDumper  100009000 is in exception list, allowing to load

Are you still monitoring via HwMonitor?

 

[hackatos]

Not anymore. I'm thinking about a downgrade.

 

[RehabMan]

Not anymore. I'm thinking about a downgrade.

Downgrade of what?
