CubeMX 6.4.0 STM32H750 Clock Issue

There seems to be a bug in the clock configuration for STM32H750XBHx. D1CPRE clock should be able to go up to 480MHz, but Cube won't take anything higher than 200MHz. HCLK is affected as well, can't set it to anything higher than 100MHz

No such issues here.

Probably your VOS value is not compatible with 480 MHz. Should be VOS 0.

Ahh. It’s my first time playing around with the H750 and didn’t know there was other settings involved with the CPU frequency. Thanks!
