@sergioad i'm not familiar with overclocking the pi 4, but in the documentation i found this about the overvoltage

CPU/GPU core voltage adjustment. The value should be in the range [-16, 8] which equates to the range [0.8V, 1.4V] with 0.025V steps. In other words, specifying -16 will give 0.8V as the GPU/core voltage, and specifying 8 will give 1.4V. For defaults see table below. Values above 6 are only allowed when force_turbo is specified: this sets the warranty bit if over_voltage_* is also set.

if this is correct, the maximum value of overvoltage is 8?

and what about force turbo do you have enable it?
