Original was : 3,3 GHz with temperatures idle = 25-30 Celsia, load = +-50 Celsia. I OC to 4GHz with 1,1V temperatures are idle = 30-35 Celsia, load = 60-65 Celsia. Is that ok? What you think? And i have two questions. 1/ What about CPU ratio mode? Fixed or Dynamic? Is good when CPU will be always on 4GHz? Or dynamic freq. but that will changing every time i dont know what i need using for better experience and life of my CPU. 2/ What about turbo mode when CPU is OCed? Off? On? Why? Thank you for your answers.

I favor dynamic settings, but with those temperatures you'd be just fine using a fixed ratio. Turbo wouldn't significantly boost these speeds; I'd skip it for more stable temperatures. For everyday overclocking, I usually stick to a 75c guideline, though anything below 80c works just as well.

I enjoy the 4Ghz voltage though I dislike the heat. What's your cooler setup? The CPU seems capable of reaching 4.4Ghz easily with strong cooling.

I appreciate the 4Ghz voltage but dislike the heat. What cooler are you using? The CPU seems capable of reaching 4.4Ghz with good cooling. I'm using a Ninja 4 air cooler and believe 4,4 is achievable.

Hello, sorry my English isn't very good, so here in a few words:
Original was : 3,3 GHz with temperatures idle = 25-30 Celsia, load = +-50 Celsia. I changed to 4GHz with 1,1V temperatures are idle = 30-35 Celsia, load = 60-65 Celsia. Is that okay? What do you think? And I have two questions.
1/ What about CPU ratio mode? Fixed or Dynamic? Is it good when the CPU is always on 4GHz? Or dynamic frequency but changing every time I don't know what I need for a better experience and CPU life?
2/ What about turbo mode when CPU is OCed? Off? On? Why?
Thank you for your answers.
You can easily go up to 4.2 GHz with 1.1 voltage. I did it with mine, and it was completely stable. Are you overclocking for gaming? If so, what GPU do you have?

4,2GHz with 1,1? I dont know if will be stable but it be more hotter (more temp) and im now in full load in +-65 i dont want to go more. GPU GTX1070. And i OC because i streaming and rendering videos.

I checked 4,2GHz at 1,1V and it works stably within -70°C. It's unclear whether I stay here or switch back to 4GHz with lower voltage. For testing 4,3GHz at 1,1V, my PC fails to boot into BIOS. I need to press the CMOS reset button on my motherboard to reset the BIOS settings.

I would keep the 4.2Ghz setting. In reality, using that lower voltage would mean needing improved cooling, aiming for 4.5Ghz instead.
