With regards to the Raspberry Pi, customers locally love pushing the boundaries of what this tiny laptop can do. At present we’ve received a maker who’s demonstrated this effort in his newest hack with some notably spectacular outcomes. Ivan Kuleshov, aka Merocle, has deliddled (eliminated the built-in warmth spreader) a Raspberry Pi CM4 and managed to overclock it to succeed in a most pace of two.5 GHz. Overclocking any mannequin of Raspberry Pi is feasible, it simply want the proper config, and loads of cooling.
In keeping with Kuleshov, he not solely overclocked the CM4 but in addition managed to keep up a great diploma of efficiency stability. The one caveat for guaranteeing the efficiency is managing the warmth. Kuleshov explains that the temperature should be stored below 6 levels Celsius (42 levels Fahrenheit). You could find an in depth take a look at the overclocking benchmarks over at pibenchmarks.com.
Delidding the SoC shouldn’t be for the feint of coronary heart. Requiring a gradual hand and a pointy blade to fastidiously take away the lid and get entry to the SoC beneath.
From a software program viewpoint, the overclock is actually 5 strains in a config.txt file. The true talent is in retaining the Pi cool.

This isn’t the primary time we’ve seen a maker overclock the Compute Module. Final 12 months we coated one other overclocking venture put collectively by maker Claude Schwarz who managed to succeed in 3 GHz with the CM4. Each of those overclocking efforts are spectacular as they each at the least double the preliminary processing pace of the Raspberry Pi CM4 which normally caps out at 1.8 GHz.
