With my newly created raspberry pi cluster being made out of the Raspberry Pi 2, I don’t want it to lag to far behind the freshly announced Raspberry Pi 3. To try and keep up with the new hardware without replacing all of my Pi’s I devices it was worth a go at overclocking them.

Overlooking my Pi’s should allow them to work a bit quicker, but it will reduce power efficient and increase the tempurature that the cluster runs at. Overclocking can be a dangerous game, as if you run the Pi’s to hard you could easily cause hardware damage to the boards if the tempurature gets to high. Thankfully there are plenty of guides on the Internet to talk you through sure tasks which is what I used.

All you have to do is edit the

sudo nano /boot/config.txt

I then added the following at the end of the file, which increase not only the clocking frequency, but also the sdram and core frequency. It also enables over voltage and sets an upper temperature limit.

arm_freq=1000
sdram_freq=500
core_freq=500
over_voltage=2
temp_limit=80 #Will throttle to default clock speed if hit

After which all there is to do is reboot the Raspberry Pi with

sudo reboot

Now time to test some code of my cluster and see what the performance increase is
