Raspberry Pi CM4 (delidding or scalping)
I scalped the Raspberry Pi CM4 and reached 2.5GHz
Of course, it's not safe; you definitely lose your warranty and can damage the device.
I used Compute Blade RC2 of my own design. CM4 Power 5.1V up to ~4.5A
It was necessary to keep the temperature no higher than ~6 degrees Celsius. Compressed air was used for cooling.
