Should I turn "AMD Cool n' Quiet" on or off?

[MoonlightSylv]

So there's a setting in my BIOS called "AMD Cool n' Quiet" which is supposed to turn down the CPU clock speed and voltage when you don't need it similar to Intel speedstep. Should I turn this on or off? It doesn't seem to effect my Cinebench score but would it improve/decrease the lifespan of my CPU or make something unstable?

Dont think it would really increase lifespan of CPU much, but the fans would be quieter (Less heat for them to move). No reason not to do it.

I would keep it on personally unless you notice an affect on your performance. Having lower temps overall would be a boost when the chip doesnt need the juice and less noise... worth it IMO.

for some reason having it enabled messes up overclocking for me. like it'll suddenly downclock to 1550mhz and get stuck, only way to fix is rebooting. so i leave it off. the CPU runs at full clocks all the time tho

Well it basicly lowers the clock speeds on ur cpu when not needed. Its 100% worth it,tho if it messes ur overclocking  then if u turn it off u are shorting the lifespan (not much),and u are getting your coolers much louder. If u need an oc guide for fx series check out jayztwocents guide.

Task manager says it runs at 3.2-3.7GHz but HWMonitor says it's minimum and maximum is 3.8GHz, which one should I trust?

That is really a problem huh? I'd say go with task manager.... Reset ur cmos. And then start oc and tell mr what happens?

That's a bit extreme for this "problem" imo

 

Also I have a Ryzen CPU not an FX CPU.

Realistically, unless you notice a performance degradation such as really low FPS in games, bad benchmarking scores attributed to CPU usage etc.. leave it on.
