Oops! Don’t overclock your Raspberry Pi too far!

A polite warning for you all! Whilst preparing the last tutorial in a 3 part series on installing Nginx, PHP, MySQL and WordPress, I decided to push my test Pi a little further to squeeze every little bit of power out of it…

Taking it to 1.1GHz the chip went pop – Fail. The result – a dead Pi! Stick to the overclocking parameters in Raspi-config people, lesson learned.

    This is a very sad story…but a possible opportunity; is there a “What to do with a dead pi” tutorial in the works? 😉

    Sorry for your PI, where you using an heatsink?
    Actually you should install 2 heatsinks: CPU and GPU
    There are also heatsinks with a small 5V fan

    I experimented with overclocking as well but kept it reasonable. What I found with the Raspberry Pi B is that only a moderate overclock seemed to make a noticeable difference. I use 850 for the CPU and I don’t use overvolting. It doesn’t seem that you get much performance boost with the higher settings and I think I may have been getting a little less than my 850 CPU overclock. I think if it runs and doesn’t have crashing issues people assume it’s fine, but it could be running hotter and not even getting as good of performance as a lower overclock. Think race car running around track a little too fast and bumping the walls as a result. Either that or I don’t have a power supply able to properly power with that high of an overclock. They get fussier about that.

    I just got a Raspberry Pi 2 and I’ve only overclocked the GPU on that one. It doesn’t seem to need it. You might want to consider moving over to the Pi 2 if you haven’t already. Nginx can be configured to run a process for each processor.

    Also, if you are looking for more performance you might want to experiment with using redis. I never tried it with the Pi, but it’s what I’m using now on the NUC. Do a web search for “redis nginx wordpress.”
