Overclocking question regarding downclocking.

[Morata]

I have my binned and delidded 8700K running at 4.8, -1 AVX, oh, and 1.2V, I wanted to know how to get it so when it's running super low usage, because I run 24/7, how to allow it to lower its clock speed dynamically.

Generally unless you are forcing an overclock it doesn't run full on, what clock does it say in task manager idling?

I don't know what you mean, but I set it to run, and it runs at 4.76 all the time.

turn on c-states will allow the clock speed to drop. Using adaptive voltage/offset voltage rather than manual allows the voltage to drop.

Okay, I am trying to figure out how to get it so my CPU doesn't run 4.8 24/7 like it is now, and I think I need to increase the voltage a tad bit because my Sony Vegas render blue screened today. This chip is binned, delidded with LM, and can run 5.1 at 1.41V with -2 AVX.

 

What V should I run at, and how do I get my CPU to downclock on idling because it runs 4.8 24/7.

Try auto voltage first and check the core voltage under full load (say, Prime95's 'In place Large FFT' test). Might want to check the temperatures as well. Go to offset mode and apply the offset you want if needed, say auto voltage gives 1.3V, you apply -0.05V offset, the CPU will receive 1.25V next time.

enable c-states and EIST

So I turned on Balanced mode and it is now running anywhere from 1.3G all the way to 4.8G, but I do not want to pump all this voltage unless it is under load so what should I change, this is an MSI SLI Plus Z370 board.

leave CPU core voltage to auto first

How can I monitor voltage while booted, because it is probably going to blast.

It says 1.336 on CPU-V and it doesn't move... The clock does, but the voltage doesn't.

Update, I enabled adaptive mode and when it downclocks, voltage is usually around the 0.8 range, sometimes a bit higher, and when under AIDA64 load, 4.7G, adaptive on, no manual voltage set, it runs at roughly 1.28 I believe.

 

If you think this is what I originally wanted, then I am good. I am trying to figure out that if I put in 1.22 or 1.23, will it still use adaptive so when it is not under full load, it will undervolt the CPU, or will I need to use offset mode, my board also has an adaptive + offset mode.

 

Have 1 more question, why is it when I switch to high-performance mode, even when I set the minimum processor state to 0%, it still runs at 4.8G 24/7?

not sure how adaptive works, never get to use something new enough to have it. You can try a -0.05V offset though and see what happens

 

high-performance mode do that because that can theroretically give better performance by removing the need to raising clocks when there is load.

Hey, if you want to pop back in here and see if you can help at all, I am looking for whoever has an idea about this haha!

 

I put in a bunch of new information so people can help me with a better understanding of my view.

[itisme911]

ok cntrl x task manager performance what clock is your cpu running at?

Also it seems you already have dynamic clock speed or the setting that does the same enabled in your bios, mt suggestion is set it to power save mode or turn down max your cpu/gpu? canboost up to unless you know you will be needing it. (Or let windows decide and just let it be)
