Hi, I have a fedora22 SuperMicro system operating as a mail server that has no need to have the CPU throttled. I'm having trouble figuring out how to disable the throttling. There also doesn't appear to be any recent threads discussing this previously. It appears some are running at full speed while others are not: # cat /proc/cpuinfo |grep Hz model name : Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz cpu MHz : 1875.187 model name : Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz cpu MHz : 2188.687 model name : Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz cpu MHz : 2399.906 model name : Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz cpu MHz : 1475.812 model name : Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz cpu MHz : 2075.437 model name : Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz cpu MHz : 2340.750 model name : Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz cpu MHz : 1262.062 model name : Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz cpu MHz : 2111.812 I've searched for the programs I've used in the past, including cpuspeed and cpufreq-* but they appear to no longer exist. I've looked in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor and all are set to "performance". What is the procedure for disabling CPU throttling permanently? Thanks, Alex
On one of my machines: # cat /proc/cpuinfo | grep Hz model name : Intel(R) Core(TM) i5 CPU M 560 @ 2.67GHz cpu MHz : 2667.000 model name : Intel(R) Core(TM) i5 CPU M 560 @ 2.67GHz cpu MHz : 2667.000 model name : Intel(R) Core(TM) i5 CPU M 560 @ 2.67GHz cpu MHz : 2667.000 model name : Intel(R) Core(TM) i5 CPU M 560 @ 2.67GHz cpu MHz : 2667.000 Notice there is no throttling.
