Question amd ryzen staying at 3.9ghz

[Questions3]

CPU is staying at 3.9ghz in CPU ID until I go to amd ryzen master and hit reset then it's back to fluctuating. I went into bios to core ratio and it stays at 3.9 after resetting to 4.2 ... goes back to that... why?

What power plan do you have in place? If on high performance it will stay near the top of it's ability.

I am using AMD ryzen high performance...

 

[Questions3]

if I change core ratio in bios it gets back to default 3.9 doesn't change to 4.2

So you change is not allowed, and/or, not valid.

some unknown mainboard with unknown BIOS version on an unknown chipset will not let you change a BIOS setting for some unknown setting pertaining to an unknown CPU, possibly a CPU/cache ratio?

Do I have the 'facts' straight here thus far??

 

[mdd1963]

Fluctuations in core speeds are normal, especially under an 'all-core' load; you may also have power/TDP limits that can be removed that might artificially keep you at lower clock speeds, as power usage/demand and TDP goes up quickly for each step above 4.0 GHz...

 

[Questions3]

is there anything I can do to change it?

This is normal when using AMD Ryzen High Power profile. Even thought it is clocked at those speeds at idle the CPU isn't under load so it's fine. Personally I use AMD Balanced and it is clocked a little lower while idle and boosts fine when needed for gaming.

Start with stating motherboard make / model / revision, BIOS revision, CPU. And why you think you should be able to do that.

Mine, as well @mdd1963' crystal balls are broken...

Try checking if AUTO OC is on in the bios, disable it if its on.
My motherboard OC my Ryzen to 3.9Ghz when set on Auto oc.
