The normal speed is 50MHz, and the fast speed is 108 MHz, i saw that 350/7 = 50MHz and i only saw errors passing passing 346 so, maybe we can find a way to change that?

No, i mean the microcontroller, no the microprocessor, check the Raspberry Pi Pico, is a silicon maded by Rasbperry Fundation itself. Here the specs:

21 mm × 51 mm form factor
RP2040 microcontroller chip designed by Raspberry Pi in the UK
Dual-core Arm Cortex-M0+ processor, flexible clock running up to 133 MHz
264KB on-chip SRAM
2MB on-board QSPI Flash
26 multifunction GPIO pins, including 3 analogue inputs
2 × UART, 2 × SPI controllers, 2 × I2C controllers, 16 × PWM channels
1 × USB 1.1 controller and PHY, with host and device support
8 × Programmable I/O (PIO) state machines for custom peripheral support
Supported input power 1.8–5.5V DC
Operating temperature -20°C to +85°C
Castellated module allows soldering direct to carrier boards
Drag-and-drop programming using mass storage over USB
Low-power sleep and dormant modes
Accurate on-chip clock
Temperature sensor
Accelerated integer and floating-point libraries on-chip
