The Raspberry Pi 400 can be overclocked to 2.2 GHz
- geerlingguy 6y agotl;dr - The Pi 400 can take a 2.2 GHz (2200 MHz) overclock, whereas older Pi 4s could only go up to a maximum of 2.147 GHz (at least for now—that may just be a firmware limitation). And the surprising result (for me) was that even after a couple hours of stress-testing the CPU, it didn't even come close to overheating, and the top surface stayed below 34°C, so it didn't turn into a little space heater for my fingers. Anyways, I thought I'd add some data regarding the overclock, performance, thermals, and power consumption since a lot of people today have been asking about them.
- rovr138 6y agoI'm really curious about the differences in the chips. I know you have a compute module too. Is that using the new chip on the 400 or the same as the RPi 4 B?
- geerlingguy 6y agoIt's using the new 'C0' chip as well. So I would assume the CM4 can be overclocked just like the Pi 400, though without the benefit of that massive keyboard-sized heat sink.
