6.7.0. STM32H745 doesn't have "Power Regulator Voltage Scale 0" in the list

I selected LDO power supply

But frequency is still limited to 400MHz.

Set the "Product revision" to "rev.V" and read the AN5337.

try just for test: use smps supply, scale 0 should be possible then.

nope, I tried different regulators but 0 is never in the list

main thing is that according to specs 480MHz available only with LDO but no matter what I do, I couldn’t set frequency to 480.

REALLY APPRECIATE YOUR HELP!!!

THAT SOLVED MY ISSUE!!!

I am on NUCLEO board, playing with collecting data, lifetime is of no concern

though ST should add this to error message when I am unable to set frequency to 480 MHz
