i5 4690k boosting higher than set multiplier

post #1 of 4
Thread Starter 
i have an i5-4690k with a msi h97 gaming 3 MB and kingston hyper x beast 1600mhz ddr3 (2x8gb)

i have set my core multiplier to 45 (fixed) and my voltage on 1.265 (adaptive; somtimes going to 1.288v) everything runs all fine and stable.
recently i discovered that my cpu sometimes boosts to 4.6ghz when gaming (light and heavy games) and sometimes during stresstesting aswell.
has anyone got any idea of how this is possible? im pleased it does boost that highbut im quite curious as i set the core MP to 45 fixed.


this is one i made today, it boosts to 4588mhz though sometimes it goes as high as 4611/4620

Is your base clock fluctuating? Those seem like odd numbers.

I know several years back AsRock was doing a thing where it would tweak the base clock, memory clock, and stuff so that it was all like synchronous for performance gains.
