Some people will do anything to increase the speed, pry open the lid Expensive i9 And put them in various cold chemical mixtures to drag every megahertz out of silicon.We haven’t seen anyone do this Extreme overclocking and raspberry pie In the past, everything had a first time.Claude Schwartz Overclocked his Raspberry Pi Compute Module 4 to an extraordinary 3 GHz.

Schwarz, he is no stranger to Raspberry Pi boards, thanks to his storm Project, taken Computing module 4 -Lite version, sitting PiTray mini Sourcekit’s carrier board-and removed the heat sink normally located above the Broadcom BCM2711C0 SoC.He applied liquid metal Thermal paste (Thermal Grizzly Conductonaut) based on gallium, tin and indium, and then replaced the radiator. In order to reach the magical 3 GHz Schwarz, several ice sprays must be used, so although this is an impressive feat, it is not the ability of the average user.
Schwarz’s earlier efforts allowed him to overclock the Compute Module 4 to 2.89 GHz, which is still a great speed increase for the 1.5 GHz stock. In addition to using liquid metal thermal paste, Schwarz also uses active cooling in the form of heat sinks and fans designed for Raspberry Pi (possibly a 52Pi model cooler) on Compute Module 4.Take steps to further overclock Schwarz. Disable the power management function to unlock higher overclocking, resulting in CPU speeds than we used Typical overclocking. At this point, we should probably say that anyone doing this is their own behavior, because these extreme behaviors will definitely invalidate your warranty, and if you try to do this, we are not responsible for anything that happens.
A bit of fumbling in the Pi’s firmware-Schwartz calls it “remove all safety nets”-the CM4 runs at an impressive 2.4GHz at 26.2°C (79.16°F). Not bad for circuit boards that start life at 1.5GHz and do not require cooling.
