I have Intel i5 14600KF - ASRock Z690 Phantom Gaming 4 - 2X32GB (64GB) Patriot Viper 3200mhz DDR4 - Gigabyte GTX 1660 Super

Compared to my old PC that I had on my old PC X79 Extreme 3 motherboard, there are many differences and I'm trying to understand how it works better.

1.
In old pc in the bios I had set the frequency of the ddr3 and the system changed them or at most it didn't work and I just had to restart to change the parameters again, but on new pc even just by enabling xmp, before starting windows it remains on a black screen for a long time, even more than 10 minutes and sometimes I am forced to restart many times before being able to enter the bios. But after the first time that it starts, everything works normally.
Now if I want to change some parameters in the bios it can happen again that I am left with the black screen for a long time so I'm afraid to go in and change something.

2.
The voltages, especially that of the RAM, I changed it manually and it worked as I set it, now with the new PC it no longer corresponds, it is lower than the one set by me or by xmp. Even under stress the voltage remains less and less.

Mainly I would like to undervolt the CPU to heat less, but I would like to understand why the screen remains black for too long and if by increasing the voltage I would no longer have this problem, in any case I would like to do some tests but without being stuck every time without being able to enter the bios.
Thanks

What BIOS version are you on for your motherboard? Which slots are the rams populating on the motherboard? If you're manually setting the voltage for the ram to be lower than the one that comes baked into the X.M.P profile, what sort of timings are the rams under?

I'm using the latest version available "18.01", rams are on slot A2 B2.
I tried setting 1.30v and and they go to 1.28v...I'm starting to suspect that the power supply is starting to fail as I noticed that the 12v drops to 11.9...
