Gigabyte B450M S2H O.C. no display after overclocking

[xurmirac]

I have Gigabyte B450M S2H and Ryzen 5 1600 AF 12nm. I'm trying overclocking to 3,7GHz and +0,100 voltage for example, then reboot pc, while it is on windows loading screen, my screen shows me no display or signal. Keyboard and mouse are off but pc is still working. My headset is from front USB port and it's lights are on. I also checked the ethernet port's light and it is off. I mean all back panel has no electricity. I guessed it is due to southbridge, what do you think? Is there a solution? The values i give like 3.7GHz and +0,100 voltage are just an example. Even i try to increase too less voltage or frequence again same happening.

 

In brief, after overclock, on windows loading screen (mostly) no display or signal message occures and nothing on the back panel of mobo works. Only back panel of mobo. CPU, fans, fron ports and GPU working. Is the problem about motherboard, southbridge, or can it be about CPU? When i reset overclock, i can use without errors, without problems.

Are both of your 4 pin connectors in your 8 pin cpu power on your motherboard?

First of all 0.1 voltage upset for an oc is practically nothing I don't think it's gonna boot like this 

Second of all I don't recommend pushing that board all the much because it doesn't necessarily have the best mosfet/ vrms and capacitors layout

No, already max voltage is +0.3 voltage. Stock voltage is 1.166 sth like that, max is 1.425 voltage. Also people increase 4GHz and 1.350V with this motherboard. Although i have a good cpu cooler -arctcic freezer 34 esports duo- i cant do. As i said, these were an example, even if i increase the voltage to +0.300, again same happening.

I couldn't understand i'm sorry

And also i realized that when that error occured, monitor displays the no signal message and the "GPU" fans are working at %100. Why?

When i give more voltage than normal oc settings, it's working. I mean, this CPU is working 3.9GHz with 1.275V but I have to give 1.375V for 3.9GHz. 3.9 - 1.375 is working but why does it want too high?
