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 ?

[Matt_AMD]

Not as far as i am aware unfortunately. 

[mostafagamal]

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

maybe that option is visible in a certain versions.

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.

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

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

Windows usually gets the chipset drivers off windows update

check to see your BIOS is reset to optimal as a baseline

[murat28]

the problem is not just windows i am having problem on bios

[Matt_AMD]

I'd recommend contacting your motherboard manufacturer.

I applied to asus service, I am waiting for an answer.

TUF x570 does not have BCLK option. 
check it
BCLK and Spread spectrum options in bios : Amd 

mailed asus. i think a few ASUS x570s mobos has a that BCLK disable option. 
3700x  stock bus speed 99.8 it means 3.59mhz
if u disable Spread Spectrum / BCLK , bus speed raising 100 and 3700x works on 3.60

Asus SAYS only High-END MObos has BCLK disable option.

So DO NOT BUY low mid ASUS x570 mobo,

Cos u cant use your CPU %100

i never buy again Asus Mobo

Spread Spectrum and BCLK options are not available on my motherboard
