Are my clock speeds too low?

[Borgus Bohr]

Is it normal that my ''idle'' clock speeds on a 5900x, would be in the mhz level? (see image) 

I never seen that low before...

 

 

thanks

what software is that so I stay away from it??

[xg32]

use ryzen master

[freeagent]

Its HWiNFO64, I think.

That's normal.

don't worry about the idle clock, the lower the better for your electricity bill.

what you want to check is the load clock.

I don't think AMD processor idle below there reference (or bus) frequency. I believe 800mhz is the lowest P-state of a 5900X processor.

@Borgus Bohr

With Intel CPUs, the Effective Clock data that HWiNFO reports is only meaningful when all cores of a CPU are fully 100% loaded. When not fully loaded, you might see MHz numbers reported that are well below the minimum speed that the CPU actually runs at. That appears to be what your screenshot shows.   

 

When running Windows 11 on an Intel CPU, you have to disable the new Windows 11 virtualization features so monitoring software has direct access to all of the CPU registers. Monitoring timers within the CPU might not be accessible if some of the virtualization features are enabled. I am not sure if this issue also applies to AMD CPUs. 

 

For Intel, things like Hyper-V, Virtual Machine Platform, Windows Hypervisor Platform, Windows Subsystem for Linux and Android and the Windows Core Isolation - Memory Integrity feature need to be disabled to give monitoring software full access to all of the CPU registers. When monitoring software does not have full access, some of what it reports might be completely wrong or make no sense whatsoever.

This is not the "physical" frequency of the cores. They change much too fast to be reported like that. It's an average over the polling period that accounts sleep at 0 MHz.

Maybe i'm reading this wrong by Ryzen Master is reporting quite low clockspeeds per core on my 5800x. Most cores are actually sleeping in this screenshot.

So it just displays "something"? 

The pulling rate on the software is typically 1000ms. I believe you can change that in hwinfo64?

 

So, help me out with terminology please.

 

Gated =

Parked =

Sleeping =

All refer to different levels of sleep.

C0 = Awake, executing code.

C1 = Core parked, still energized

C3 through C7 involve various states of power gating to save power. The "deeper" the state, the longer and more energy is needed to "wake" the core back to C0.

Right gotcha.

Sometimes I get a little taken off track because I often refer to C0 that utilizes the processor P-states. 

C3 and above is clocks off then. Should report 0mhz. 

 

So this software that reads temp sensors that aren't there, you just get some random number. Just it's doing it with a frequency, that isn't there. I'm saying gated cores aren't running = clocks off, cache off. 0mhz. 

 

(Am I close?)
