You will need an actual overclocking app like Quickclock or JRummy's Droid Overclock, SetCPU is used for setting frequencies and using profiles
JRummy's Droid Overclock can perform same function as SetCPU, including profiles and all that. Overclocking function does not work very well for me. I am actually using the profiles option only to underclock under certain conditions, which actually gives me on average 25% longer battery life compared to stock. I use jrummys as I had paid for it anyways already.
If you need profiles only, SetCPU is the way to go, if you want to try over/under-volting/clocking- droid overclock by JRummy. Again - D2G support is not stable, at best...
