The truth is that the vast majority of them were not very useful. If you read a dictionary beforehand, like the one I sent you along with a simple guide, you would know what the main parameters are, and even which values are the most recommended for them.
If you lower the multiplier but increase the FSB (CPU frequency), you can reach the same figure. It's as simple as:
200 x20.0 = 4,00 Ghz
225 x18.0 = 4,05 Ghz
By the way, I told you earlier "for example 300" in the FSB but I didn't do the math, that would be 5,4 Ghz and I don't think it would be stable at first, you would have to touch voltage and more things. For now, go up as in the example I just gave you, something like 225-230 and keep going up little by little, you can lower the multiplier if necessary.
I don't know about voltages, so do a little research on google and when you know how much you can increase it, then you can deal with it.

and on top of that with the BIOS UEFI that will be the same but they change the look etc etc
