How to customize CPU frequency steps

Hey everybody,

here comes a brand new guide on an interesting topic: CPU frequency scaling. Not many of you may know that on newer generation Intel CPUs (Ivy-Sandy Bridge) the kernel governor may decide the most suitable frequency in a plethora of them. In my case, for example (i7 3720QM), I can range from 1200MHz to 3600MHz in steps of 100MHz. This might be exciting, but changing CPU frequency costs a little energy at every transition.
Furthermore it happens that in several high-end CPUs, which are the more power consuming too, they cut the lower boundary to 1200MHz, while the real minimum is 800MHz.
In this advanced guide I want to introduce you how to modify your BIOS to fully control CPU frequency steps.

Hi guys,

this time I'm making a small exception and submitting something cool in Windoze system. It happened few weeks ago that my 8GB microsd card got screwed up... with any sort of pic and video in it... my holiday pictures too.

Since it's always a pain recovering a very damaged memory card (mine was so f*cked that reading the first sectors made it invisible to the OS...) I tried any sort of program, till I came to CardRecovery.
