There are many overclocking kernels available out there and each one being specific for each release of cyanogen mod 7.1.0 rom. While you may find that most of the Overclocking Kernels developed for other releases of cm7 also work with the latest and the stable version of cm7 released on November 17, the developer recommends that you use these overclocking kernels exclusive to the latest cm7 version as previous versions might not be fully compatible with the latest release of cyanogen mod rom. Also, these OC Kernels are full of features and I/O Schedulers so you are in profit.
So, here we begin. First of all, download and install latest cyanogen mod 7.1.0 on your galaxy mini/pop, if you haven't done it already. Then all you have to do is get right overclocking kernels for your device then flash them in clock work mod recovery. Download one overclocking kernel from below that can be handled successfully by your device and then follow the steps given to overclock your galaxy mini.
