CPU Underclocking itself

Hi guys

I have the Phenom 965 BE with an ASRock 970 Extreme 3 motherboard. Recently i overclocked my cpu to 3.8Ghz (19x) and noticed the CPU clock would drop suddenly on CPU-Z

So i have gone back to the BIOS and reset everything to defaults however it seems to still be causing this problem. Every 10 or so seconds the clocks will drop for a split second and jump back up.

Any Ideas

If you didn't disable Cool 'n' quiet then it will do that.

Even with Cool n Quiet disabled, even with C1E disabled it still does it. I can't seem to figure out why

Not to mention it does this at full load not when idle

Could be the thermal protection kicking it down because it is getting too hot.

It could be overheating, check your temps..

does it downclock while idle looking @ the desktop?

Yes, but much less often.

However I recently downloaded AMD Overdrive and that doesn't show any drops at all?

Maybe CPU-Z is just giving faulty readings?

usually CPU-Z is dead on. i would suggest that AMD overdrive was giving false readings over CPU-Z. that certainly is strange. maybe it has something to do with your motherboard? i really don't know.

EDIT: i also noticed that the multiplier is set to x17. not x19. try checking your BIOS again and make sure cool 'n' quiet is disabled. if it is, enable it, boot, shut down, disable it and boot.

the reason i ask is my i3-2100 downclocks itself, not matter what settings i have in the BIOS.
speedstep disabled, C1E disabled, CPU power management disabled, even the windows power setting moved from balanced to high performance

Here are the the images with it overclocked,

I have tried disabling and enabling CnQ a great amount of times, I'm just lost now

I have also installed AMD Overdrive which do not show any drops at all

So i thought maybe CPU-Z is wrong. So i decided to install a previous version of CPU-Z which is like AMD Overdrive, it didn't show any sort of drops

The latest CPU-Z faulty reading maybe?
