AMD Ryzen 3 3700x invalid base clock speed

Hello,

as far as i know the base clock speed of AMD Ryzen 3 3700x is :3.6 GHz

i have Windows 10 Education which reports Processor Base clock Speed : 3.59GHz

the question is: why doesn't windows OS reports the full base clock speed ?

My Specs :

-AMD Ryzen 7 3700x

-Gigabyte B450 Aorus Pro Wifi

-TeamForce DarkZ 3200 2x16GB

Most likely because your motherboard has an option called Spread Spectrum enabled. 

If your motherboard supports changing this option, it may show the true base clock as it does now on my system with Spread Spectrum disabled.

After doing some research, looks like you're correct about Spread Spectrum.

but unfortunately i couldn't find that option on my current BIOS.

so .. is there anywhere else that can be used to disable it ?

May i ask about your BIOS Version ? or AGESA Version ?

maybe that option is visible in a certain versions.

Spread Spectrum has not had any impact on my machines. A clean install of windows recently eliminated a lot of problems.

It's down to the motherboard than the Ageesa code. 


I am using an Asus Crosshair VIII Hero Wifi and this option is available on every BIOS release.

I don't have a Spread Spectrum option. And also shows missing clock speed in bios.
