Disabling CPU throttling on fedora22

[Alex]

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
