Questions tagged [overclocking]

Overclocking is a method of trying to operate a processor faster than the manufacturer-specified clock frequency. Use this tag for questions about how to overclock the Raspberry Pi.

Overclocking may include increasing the operation voltage of the Pi. It might increase power consumption, thermal load, and may result in (permanent) damage to the system.

What are the overclocking capabilities?

I've not ordered mine (yet!), but I do some overclocking as a hobby to the extent that my netbook, Android phone, desktop, and even my wife's Blackberry are overclocked. Is there potential to overclock the RPi beyond stock voltage and speeds? I…

Why won't my Raspberry Pi overclock?

I edited the file /boot/config.txt to increase the CPU speed to 800MHz. dmesg includes the following line bcm2835-cpufreq: Freq 800000->700000 (min=700000 max=800000 target=700000 request=700000) Sure enough, my CPU is only running at 700MHz. Why…

Why is my Pi running at 700MHz all the time?

My RasPi is configured to 900MHz overclock using raspi-config, but it keeps running at 700MHz even under load. I have found this answer already, and my system is also running with dynamic for info in /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_* do…

Raspberry Pi Model B 3 Overclocking?

With the release of the Raspberry Pi Model B 3 today, I'm sure we're all very excited to see the speed of this new Pi. The standard clock is 1.2Ghz, but I'd like to push mine further. I know the Pi 3 uses the 64-bit BCM2837 processor, but I couldn't…

Overclocking via command line

I'm setting up a Puppet instance that will manage a bunch of RPis. This means I cannot overclock them one by one using raspi-config. Overclocking should be as simple as creating /boot/config.txt: root@rpi-032113 ~ # file /boot/config.txt…

Does overclocking affect the SPI (APB) clock?

The current config.txt allows one to change arm_freq, gpu_freq, core_freq, h264_freq, isp_freq, and v3d_freq. In addition, there is support for the kernel to change clocks on demand and based on thermal limits. On the other hand, the hardware…

"shutdown -r now" crashed after overclocking

How I hosed my ext4 file system in the first hour with Raspbian: I have always used shutdown -r now. I tried this after editing my overclocking parameters manually. I remember setting arm_freq to 900 and sdram_freq to something (!), carefully of…
