Interesting stuff. You can improve reliability by running your system at a lower speed. Here's a blog post with a summary of some of the conclusions of the paper above: http://grano.la/blog/2012/06/improve-the-reliability-of-your... (Disclaimer: that's my company's blog)

One question I still have is whether the switching of CPU frequencies has any effect, or if it is only the average speed that correlates to the reliability. Anecdotal evidence suggests that this is the case, but it could be an area for further research.
