CPU Frequency and Voltage fall every 10 sec

[Turtvaiz]

So I have been running 4,5 GHz on my Athlon II X4 760K but recently it has been falling for like 3 sec to 1,8GHz and 0,9 voltage every 10 sec. My mobo is MSI FM2-A55M-E33.

What is your temp? Could be thermal throttling.

Max 53 and fan isn't even spinning at full speed because it automatically adjusts speed.

What happens if you bring it down to std clocks? It could be your VRM's on the motherboard forcing thermal throttling which is a known issue with many MSI boards.

This only happens on 4,1GHz or above. I am running now with stock clocks and turbo enable which boosts to 4 ghz and this doesn't happen

Pretty sure it is your boards VRM's since they are not heatsinked, here recommended to add cooling for the VRM's to overclock http://www.overclock.net/t/946407/amd-motherboards-vrm-info-database

Well can you tell me what do I need to attach heatsinks to then?
