I have an i5 3570K that keeps stepping back to a slower clock a minute or so after booting into windows. Start up CPUz and there is my new 4.4 clock, them boom ! a few seconds it backs down. From say 44 to 42 or 41 multiplier
I running on a ASUS P877 V LK with Corsair Vengeance 2 x 4Gb 2133.
Any ideas ?
Here a my settings

If you have installed your cooler correctly, you may simply have a processor that is a bit slower than some. Did you play the overclock game?
A set multiplier and voltage to nominal
B run stress test Error?
C if error, increase voltage go to B
D if no error, increase mulitplier go to B
You should end up at a frequency that you cannot increase any further. This is it. Also you want to keep your processor at about 80C max so don't go so high in voltage and frequency that you exceed 80C
If desperate, you may consider de-lidding. It will allow your processor to run cooler and faster. If you want to do this, spend and hour or two watching de-lidding videos on YOUTUBE.
...... no one has mentioned this which is defiantly causing it disable c1e c3 and c6 and leave c state on auto then enable multi core enhancement and for bettter ocing put power phases to extreme/ultra high i had the same problem and disable epu etc......
