I tried modprobe-ing all available kernel modules for cpus but none of them will attach
#ls /lib/modules/$(uname -r)/kernel/drivers/cpufreq
acpi-cpufreq.ko.gz cpufreq_stats.ko.gz pcc-cpufreq.ko.gz
amd_freq_sensitivity.ko.gz cpufreq_userspace.ko.gz powernow-k8.ko.gz
cpufreq_conservative.ko.gz mperf.ko.gz speedstep-lib.ko.gz
cpufreq_powersave.ko.gz p4-clockmod.ko.gz
cpupower frequency-info
analyzing CPU 0:
no or unknown cpufreq driver is active on this CPU
boost state support:
Supported: yes
Active: yes
Any suggestions? Im at a bit of a loss and don't want my cpu running at 100% all the time.

The "acpi-cpufreq" is the right one. Modeprobe it, see dmesg and check for errors.
Offline
modprobe says 'no such device' and dmesg shows no new errors.

please post the output of lscpu , especially the CPU MHZ, max MHZ and min MHZ values.
Is your processor overclocked ?

It is overclocked using an MSI bios feature. That has never stopped the governors before, but stranger has happened

There have been cases where enabling "turbo" mode on certain processors prevented the kernel from throttling the cpu.
The fact that lscpu doesn't output min / max Mhz settings, suggests that your case maybe similar.
Try disabling the overclocking bios feature and see if linux can thriottle the cpu then.

Well it seems that turning off the auto-overclock feature in my bios fixed this as was suggested. Ill try manual overclock later , but atleast I can keep form burning mine out now.
Offline
hm, i've never used any auto overclock to start with and running my cpu at stock speeds is not an option for me
edit: loaded optimized defaults in my bios and the acpi-cpufreq loaded but still i wouldn't call that a solution
edit2: it's possible to overclock only by using offset mode when adjusting voltages what sucks big time
