Hey,
I noticed while digging around in Winbox -> System -> Routerboard -> Settings -> CPU Frequency that I can change it to 'above spec' frequencies: 500MHz <-> 750MHz (in 50MHz steps)
Does anyone else up the CPU frequency on their devices?
Are there any downsides apart from potential increase in heat/Watts usage?
I've set it at 650MHz and rebooted the router, now it seems to be showing up in Winbox's Resources page as 650MHz. So I guess it hasn't exploded yet...
