Extreme Overclocker Takes Raspberry Pi to 3 GHz

Some people will do anything for a speed boost, prying the lids off expensive i9s and subjecting them to all manner of chilly chemical concoctions to drag every last megahertz out of the silicon. We’ve not seen anybody do such an extreme overclock with a Raspberry Pi before, but there’s a first time for everything. Claude Schwarz has overclocked his Raspberry Pi Compute Module 4 to an extraordinary 3 GHz.

Schwarz, who’s no stranger to the Raspberry Pi boards thanks to his PiStorm project, took a Compute Module 4 – the Lite version, sitting in a PiTray mini carrier board from Sourcekit – and removed the heat spreader that usually sits above the Broadcom BCM2711C0 SoC. He applied a liquid metal thermal paste (Thermal Grizzly Conductonaut) based on gallium, tin and indium, then replaced the heat spreader. To reach the magic 3 GHz Schwarz had to use a few blasts of ice spray, so while this is an impressive feat, it’s not one for regular users.
