"Effective Clock" changing dynamically while overclocking Ryzen 1700X

[AriGee50]

So Im trying to rebuild my super stable 4.0 Ghz OC. After upgrading the BIOS, and of course, forgetting that doing so will reset all of the BIOS settings...Im now at it again trying to get my bloody OC back!

 

So, on my way to getting everything sorted, and keeping a close eye on things in HWinfo, I noticed the "Core Effective Clock" readouts. Now I cant remember what these were doing in my last OC, I cant be sure, but certainly, this time, they are definitely jumping all over the place. 

 

Now its my understanding that the minute you set a non standard core multiplier, all dynamic core underclocking/undervolting stops. And yet, the "Effective Clock" will jump anywhere from the actual max clock (3991 MHz) while testing in Prime95 to 36 MHz at idle.

 

So whats going on here. I looked up what Effective Clock means on HWinfo's site, but it didnt tell me a lot, and if anything made me worry more. Am I worrying about nothing? Are my clocks actually being dynamically changed even though they should be locked because of a non-stock multiplier setting?

 

Thanks everyone!

Ari

effective clock is just actual clock rate * usage if you ask me

that doesnt seem to be what the HWinfo site says

 

"Hence a new approach needs to be used called the Effective clock. This method relies on hardware's capability to sample the actual clock state (all its levels) across a certain interval, including sleeping (halted) states. The software then queries the counter over a specific polling period, which provides the average value of all clock states that occurred in the given interval. HWiNFO v6.13-3955 Beta introduces reporting of this clock."

 

It seems like its actually polling that number, not merely calculating it.

 

Thoughts?

So it seems like it's calculating (still) the proportion of times spent in each power/clock state and the frequency used in that state to give you the effective clock number. Power/clocl state is still dependent on your usage tho

but shouldnt the clock state be locked when you overclock a Ryzen 1700?

no, Ryzen can turn off part of its cores to save power. Locking the multiplier leads to the clock generator to keep its pulsing rate, doesn't mean the rest of the core cares about it

huh, ok. thought all of that became locked when you overclocked, but ok. Thanks for all the help!

Yes, and it *is* locked on all cores in the screen shot you posted. 

 

clock ≠ effective clock 

 

Nothing to worry about just how that proc works

It's the amount of time your cores are in a sleep state, I guess c6 state.  In your case an effective clock of 400mhz would mean that core is spending 90% of the time in it's c6 state.
