If the setting is not there, it's not there.

Try changing the BCLK setting from Auto to a manually set 100.0 MHz. The board might then in secret disable spread spectrum, even if it has no option for it. I'm suspecting this because on my ASRock board, the spread spectrum and the manual BCLK setting are on the same line in the BIOS screen. If I switch BCLK between Auto and Manual, then the spread spectrum setting disappears and is replaced with the input box for the BCLK speed.

That sucks, even my old FX system had the possibility to disable spread spectrum :/ Anyway I tried and seems to work, bus is 100 now, but with same setting on a strix x470 won't go above 99.8...

Done what deepor suggested andseems to work, also I'm not using docp, everything is manual.
This is a joke tho, 300$ mobo and there's still hidden options...

Do as deepor said. When you set BCLK manually it will be static, like with Spread Spectrum disabled.
Yep, it worked.

It should be in bios - tweakers paradise, first option.

Hi,
Think that sort of thing is triggered by using xmp profiles
Often if you enable xmp profiles you'd also get a popup asking if you also want to enable other enhanced oc features.

Another one is auto or easy oc bios features will likely enable stuff like this too.

HWiNFO64, cpu z shows fluctuations tho, from 99.95 to 100.12. So I guess spread spectrum is still actually on. RIP

The only thing I have in auto is the cpu ratio :/
