CPU running too fast

[Danny Harriman]

Ive just built a pc with a ryzen 5 3600 on a strix b450-f motherboard with a stick of 16gb ddr4 ram but when i turn it on taskmanager says the cpu is running at 4+ ghz when the base clock is 3.6  ive changed nothing in the bios, does anyone know how i can set the cpu speed back to 3.6ghz?

This is how ryzen and all cpus run, your cpu will boost to boost clocks as much as it can even while idle. Thats normal, you want such things. Its rather quite odd seeing base clock, outside when a core goes to sleep, or when youre thermally throttling, no need to worry mate.

Okay, thanks for clearing it up.

i think theirs a chance you have an option in the bios to turn off boost or you might need to manually set CPU settings to make it stop boosting (i take its your doing it for power savings if you know you never need to do anything super fast?)

I have the same motherboard but Intel (so it might differ slightly). Default settings should work. Check for Power Mode in BIOS (Auto should work) and ASUS Performance Enhancement (should by off by default)

 

Windows power schemes also affect clock speeds.

 

And like previous users said, it's rare to hit base speed. Try turning off background programs and don't move your mouse and wait a couple of minutes while watching the speed if you want to see it hit lower rates.

 

If the clock already jumps up and down - that means your power settings are on and you're fine
