Dynamic Overclocking?

[KSP]

Hi guys,

 

So I just finished overclocking my 9700K. Stress testing right now but it seems to be stable running 4.8GHz at 1.25v. I could probably lower it down to 1.225v, but I’m happy with what it’s at now. However, this is a static overclock, like the overclock on my old 7700K was. I was wondering what specific things I should change to get this to be a dynamic overclock? I already have the windows power mode set to balanced, but what about the BIOS? 
 

Thanks!

I'm not 100% sure what you're referring to by "dynamic" overclock. If you're looking for the frequency to lower under less utilization, make sure that intel EIST (AKA SpeedStep) is enabled. C-states also play a role in reducing power utilization when the CPU isn't being utilized much.

not sure if this is an option but see if there is a frequency offset feature? if voltage is auto then it should work fine.

Yes, that’s what I mean. I don’t want all cores at 4.8 even at idle. I just enabled EIST and I’ll look into C-states. Thanks!

If you enable the C states, you do not have to be concerned about your CPU speed when it is idle.  Here is a comparison.

The screenshot shows a huge difference in CPU speed but no difference at all in terms of power consumption or CPU temperature when idle.

 

When a CPU core enters the C7 C state, its internal clock is stopped and it is disconnected from the voltage rail.  The core is sitting dormant at 0 MHz and 0 Volts when it enters C7.  Individual cores with nothing to do can spend up to 99% of their time in this state.  Even when the CPU is partially loaded, unused cores can be in C7 saving power.  Forcing Intel CPUs to run slow is not necessary when the C states are enabled.
