CPU frequency not stable after 'little' mistake

Hi everyone,

After many years of building pc's (>20) I decied to upgrade my closed loop to a custom loop. While unmounting the cpu (a i7-6700k) I contemplated if that black piece of plastic that was mounted in there with it (like a help thing i tried to use as it was recommended) was correct? I removed it and tried to 'manually' fit the cpu there like I've always done. Went like a charm.

Anyway, so I remove the cpu again to clean it and I see that like 2-3 pins on the motherboards cpu socket are bent. I didnt manage to really bend them back but after finished the custom loop I decied to try and start the cpu up and everything seemed normal except for the fact that the bios warned a new cpu had been installed.

My question is this. After booting into Windows and fire up the app CpuTemp (or is it CoreTemp? Can't remember) it shows the cpu frequency alternate between 800Mhz and 4.2Ghz. After bending the cpu socket pins, is this the result?

What do you think guys? Appreciate any insight I can get into this.
 
Solution
It sounds like intel speed step is working properly. It lowers the cpu clock speeds to 800mhz when idle (very little processing load) to reduce temps and power consumption. When need for processing power increases, it clocks up to its max/turbo boost speeds. It's not uncommon to alternate back and forth, that's how it's designed.

This is probably due to the fact that i tried to use a EKWB thermal paste solution called TIM and it didn't seem to work that well (the pase didnt spread)... So hopefully my MB isn't broken then and this alternating between 800 and 4.2 is due to bad cooling on my part.
