Octane III CPU Frequencies in Idle

[David010203]

Hi guys,

So, I've been playing around with the CPU control panel after many good tips I've received on this awesome forum. I'm currently running this setup and it's stable.

My question would be about the fact that the CPU is running max frequency all the time, even when I'm not doing anything. Is this happening to you guys as well and I shouldn't worry about it? Or if there is a way, I'd like to learn how to get it to "adapt" clock frequency based on load.
Also, what is the Power Limit Option doing? I think if I turn that down, the clocks would go lower, but probably would affect stability.

Cheers!

Adaptive frequency should be controlled by Windows in your advanced power options. Try selecting "power saver" and see what your clock frequencies are. In standard mode it should drop as low as 2ghz when idling, in performance mode it will generally stick to 4ghz.

Power limit is basically a throttle option. It allows the CPU to take a certain amount of power over the capped normal (90w I believe) for a certain amount of time before dropping back down. There's no point in messing with it at this level though.

What is your goal? Is it to have the battery last as long as possible? You will find that battery mode already has all that in check, or at least it should if you haven't messed with it. I found it pointless though, it only netted me about 10 minutes extra usage

Hi The_Scotster,

Thanks a lot for the reply. I'll leave the Power Limit on the default 95W then.
What confuses me though is, that all the cores are set to 36x, but the clock frequency is 3960-4000Mhz. Since it's 36x, shouldn't the clock frequency be 3580-3600Mhz?
This happened to me yesterday: I was gaming with some friends and the laptop kept changing brightness and one time even wanted to go into projector mode for whatever reason and I was really confused. At first, I thought it might be the webcam adapting brightness to room lighting, so I disabled the webcam. This still didn't solve the problem and the brightness was still changing from time to time, randomly. Second idea I had was that the power cable might not be plugged in properly so I unplugged the cable and plugged in back in. I did this while in the game...bad idea, it messed up my fps and performance so I had to reboot the laptop.

Before the reboot, the CPU was running at 3960Mhz like in the picture I posted previously. After the reboot however, the CPU is running at 3580Mhz as a max, which makes sense considering the 36x setting. I don't know why it was running at 3960Mhz before. Apart from this, my temperatures went higher with almost 10 degrees in my CPU, cranking up my fans.

What do you think might be causing these weird things haha?

Thanks a lot!

I have no idea to be honest. Like yourself the only thing I can think of is that the power cable wasn't in properly. The brightness certainly shouldn't be randomly adjusting up and down.

Regarding the frequency, sometimes a reboot is required for certain settings to take effect. I don't know why this is but I have noticed the same. You should be able to set the frequency at whatever you like, I still don't understand why you would go with 3.6Ghz though, there's not really anything to be gained by holding the CPU back.... unless you plan on significantly dropping the voltage?

Is it temperatures that you are having an issue with? You shouldn't need to cripple your system to get them in check.

Pretty much, yes, I'm always monitoring temperatures and fan speeds trying to keep them in good limits. I'm sometimes doing longer play sessions of like 8 hours, Witcher 3 for example gets my CPU and GPU to ~70C with fans at around 4300RPM constantly and I am always saying to myself: "THIS IS NOT HEALTHY FOR THE LAPTOP!". But I tend to believe I'm overreacting and worrying too much over it and it shouldn't be a problem.

70C is perfect for a laptop. Anything inside 85C is perfectly fine for both CPU and GPU

You should be able to run your PC at 4.0GHz and -150mv without any issues at all.

As usual, thanks for all the help The_Scotster, changed my CPU to 40x and -160mv. Hope you have a good evening!
