I believe you can only overclock a non k CPU by increasing BLCK, but you can not change multiplier. You might be able to change voltage to CPU but I am not sure, it has been a few years since I used a non k CPU so I forget. Maybe someone else can help you better regarding CPU voltage.
Volt I can set it manually without problems.
But I want to OVERCLOCK him.
One of the problems I observed was the XMP 3200MHZ
It gives me a bios 1.350 but in winds I reach 1.45V it is too much to my taste.
Is there no good bios and hacking for NON K processors to OVERCLOCK?
To motherboard Z270H?
As I said a non k CPU can only be OC by increasing the BLCK. The RAM can be OC either manually . Or by XMP, followed by tightening the Primary, Secondary and Tertiary timings including RAM voltage.
I doubt that your RAM voltage set to 1.35v in BIOS is actually getting 1.45v continuously. If so then it might be a software error? If your RAM is continually using 1.45v then you might need to try 1.2v for vccio and vccsa in the BIOS. But I believe it's normal for voltage to reach 1.45v for short periods when the RAM is under heavy load and the RAM needs or wants more current.
Not that I'm aware of. It is not a BIOS limitation, but a locked CPU multiplier limitation. I do not know of any hack or tool that can hack a CPU to unlock the multiplier.
I can only suggest to join the win-raid forum and ask if anyone has a modded BIOS for your needs. You need to subscribe to the forum and make a request for a BIOS Mod at https://www.win-raid.com/f54-BIOS-Modding-Requests.html
