CPU at max frequency while idle

[MYX]

I have a ryzen 7 1700 OC at 3.65 ghz but even at idle the cpu stays at 3.65 ghz, is this normal? or is should the CPU go back to its base 3.0 ghz clock?

Thanks

At idle it should go much lower than that, like 800MHz? not sure on the exact value though

 

Did you turn off C-state / Pstate when overclocking?

Check the advanced power settings in Windows is the minimum CPU state is set to 100%, if yes, change it to 5%

where do I find advanced power settings?

I found it and it says its still at 5% minimum

I just used the asus AI overclocking tool

Using performance power plan?

Yes. Once you manually overclock, it's my understanding Ryzen 'should' automatically disable most power saving features (regardless of bios setting), including those that allow Windows to reduce voltage and frequency at idle. I've overclocked my Ryzen 5 1600 to 3.9GHz and it stays there regardless of load or Windows Power Plan. This doesn't mean that your system is consuming great amounts of power. Idle is idle.

 

I'll provide you with a few links that have helped me understand how Ryzen works. Much of it is beyond me, though. Maybe you or someone else can benefit from them.

so since my cpu is always at 3650mghz, could this hurt the system in any way? if I'm not benefiting from it should I just put it back to its base clock?

Well, overclocking in general hurts a system. This is just how overclocking works. You push the system beyond spec and force it to work harder and consume more power than intended. It's a matter of weighing the benefits received versus the damage caused. Nobody will know the actual numbers, but your CPU overclocked to 3.65 may last 10 years now instead of 15. Is it worth it to you?

 

Your Ryzen 7 1700 has a base clock of 3.0GHz. At Auto settings, it'll automatically overclock all eight cores to 3.2GHz. If your temperatures are within safe ranges (likely below 80c), one or two of your cores may boost to 3.7GHz with AMD's XFR technology adding an additional 50MHz on top of that. But at full load, you're likely to see 3.2GHz most of the time.

 

So your CPU already over clocks two cores to 3.75GHz. If that's good enough for you, or if you're worried about damaging something. Click the "Reset bios to defaults" setting and let it run at stock settings.
