Re: mcelog

The internal CPU PROCHOT sensor is seeing a temperature above a preset threshold and is throttling the CPU back to help lower the temp.  Check the system cooling,  and/or the CPU heat sink. The heat sink could be installed improperly, or  possibly no enough thermal grease was applied to the CPU. 

 

If the hardware is OK, you may need to change the system cooling setting to increased or maximum cooling.  I've seen a few cases where optimal cooling and just the right workload would trip CPU throttling as iLO wasn't ramping up the fans quite fast enough

Re: mcelog

Thank you Jimmy. I will apply the thermal greace and monitor the server behavior
