Question Need help with overclocking CPU and GPU

[nawabkhan_u]

I have some doubts about overclocking. Pls help me

1. What are the softwares used for overclocking(pls give seperate list for intel and amd) ?
2. is overclocking safe with good cooler and acceptable temperature or it will decrease the life span of motherboard because of voltage increase even with good cooler?
3. how much performance increase by maximum overclocking cpu and gpu in percentage from stock settings ?
4. after overclocking while testing stability screen goes black because of not enough voltage.

I restarted the pc but screen remains black.

In windows 10 we have only option to enter bios inside of operating system.
There is no shortcut key like f8 f10 to enter bios.
Then how to enter bios if screen is black?

1. from which frequency I should start overclocking, base frequency or turbo frequency?
2. At which rate should I increase voltage?
3. Does graphics card overclocking improve performance?

If you restart and keep pressing delete it should let you enter a bios. Overclocking is safe as long as temps and voltages are kept under control. If exceed these then could lead to bad things happening. On Ryzen would not say there is a lot of room for OC. For me OC offer the way to undervolt cpu and bring temp way down but it still as fast.
