Hello guys,

I have my i7 6700k overclocked to 4.6ghz through the ez-system-tuning feature on my z170 deluxe. It overclocked my multiplier from 42 to 45 and the bus from 100 to 103. On CPU Z under 100 load it says that the core is at 4.6ghz (bus 103, multi 45) but does that actually mean that my CPU is overclocked to 4.6 or is it 4.5 since only the multiplier gives speed to the CPU?

Thanks.

@basroil already explained this. Your CPU speed (core frequency) is equal to BCLK multiplied by the CPU multiplier (hence the name). So in your case, CPU speed = 103 MHz x 45 = 4635 MHz = 4.635 GHz.


Your CPU speed is the product of the BCLK and multiplier, so they both affect the final speed equally.

the bus overclocks other components aswell such as the ram and pci-e etc, whereas the multiplier overclocks the cpu only which is why I asked whether it's actually 4.6 or 4.5Ghz
