Ryzen 5900x C&Q Stepping Down Frequency in Windows 11

 

Haya,  

            I`ve just upgraded my rig from a 7th gen I9 (sad...miss it) to an AMD AM4 build with Ryzen 9 5900x and I`ve noticed something very odd, the Task Manager as well as few other "spec" wise apps show my CPU frequency apparently always at high frequency.

I`ve also checked with Ryzen Master app and this one shows correctly the CPU stepping down in frequency when the load is minimum.

I`m not sure if it`s an Microsoft issue or AMD issue, but this is bugging me as I`m sure what app/reality to follow.

Just for reference, my MB is Gigabyte B550 Aorus Pro V2 (rev. 1.0)

Can you please help ?

Thanks,

Andy

Hi, fortunately, this is a crowded community and sometimes its easier to miss certain topics.

But here goes. Task manager is not the best place to check frequency. Sure, you can have a look at it sometimes but its far from ideal. Ryzen Master would be the best place for it but if you want to doublecheck, just get HWiNFO64 which is a bit more comprehensive.

Inside HWiNFO64 you will see per core clocks and per core effective clocks. You should follow the first ones.

If for some reason, they stay up there unchanged, go to power options and lower the minimum processor state, this should bring them down.

 

Good Luck

Wow.......nobody has an answer for this

eL3cTr1c4L, since MS has never said what the frequency in the Task Manager is for multi-core processors, there is no way to compare to Ryzen Master (RM). So if you really want to know the frequency, rely on RM only. Enjoy, John.

Not sure that it's still referred to as Cool'n'Quiet, but in my experience with AM4 most 3rd party apps such as CPU-Z and Core Temp will not reflect a speed lower than the processor base frequency, even when Ryzen Master indicates a much lower sleep speed.

As @misterj states, who knows what calculation Microsoft is using to reflect speed. Go by what Ryzen Master shows as the most accurate data.

Actually, coretemp give me lower than base clocks, but I just use it for quick look on the temps.

Thanks for all the replies fellas.

Seams like I don`t have to rely on the Task Manager anymore, it`s a shame because on Intel I didn`t encountered this issue, worked "out of the box" as they say.

HWiNFO64 does the trick, thanks again for the suggestion.

OP can close this thread.
