Bios
The bios used on the B365M Phantom Gaming 4 shares the structure and design with other ASRock motherboards. There is no EZ Mode page available, instead, the bios will boot up into the Advanced mode.
The interface is simple to use and the menu layout of each page is unchanged when compared to other ASRock motherboards.
Did you enable as Base Frequency Boost? Did it help increase the max turbo clock speed?
It was enabled and it did help, but not a lot.
