    I'm wondering if someone can explain this setcpu profile to me. I'm following the recommended setting from this guide: http://www.droidforums.net/forum/hacking-faqs/47871-overclocking-101-a.html#post507815

    The person is using a 1000 GHZ kernal, but the highest mhz is only 800. If that is the case, why not just use a 800 kernel? If people are wondering why I need my clockspeed to be so high, it is because I'll be using psx4droid on my trip later this week.

    Also, I can't seem to get 125. Is this because I'm using a different kernel?

    Thank you

    screen off 400/125
    temp 44.9 500/125
    charging/full 800/125
    battery <21% 400/125
    battery <41% 600/125

    the highest should be 1Ghz - did you do autodetect? and i havent used a kernel in a while but it might not be one of the preset spots on that kernel

    Different kernels have different slots. For example, the kernel he's talking about may have 7 slots, as follows.
    125mhz < 400mhz < 500 mhz < 600 mhz < 700 mhz < 800 mhz < 1000 mhz
    While your kernel may have 7 slots, ranging from 300 mhz to 800 mhz.. (not actual values, just examples..)
    The reason he might be using a 1000 mhz kernel and only be using 800 mhz is because of the slot values..
    Does that make sense?

    Yes, it is on auto detect. I will try to on device selection and see if I can choose 125.

    Also, the highest is set to 800 in charging/full option, but 1000 for time in state is still increasing... I'm kind of confused by this.

    Further explanation will be greatly appreciated.

    Agh, I don't know how to explain this!
    Each kernel has a set number of different slots, each slot holding a certain value. Not all kernels will go down to 125 mhz, just like not all of them will go up to 1.25ghz.
    So say he SPECIFICALLY wants 125 mhz.. Well, the kernel that only goes to 800 mhz might not have 125 mhz as an option, but the one that tops out at 1.0 ghz does go down to 125.. That's why he would choose 1ghz over 800mhz

    OK, so you've got the idea that a kernel has 7 slots...7 speeds it can select. If you want a good way to compare different kernels (min speed, max speed, and intermediate speeds) I recommend looking at psdroid's list, it makes shopping for a kernel pretty clear:

    P3Droid Kernels

    I'd strongly suggest you pick one out (probably this one if you want to go from 125 to 1000: 1000 = 125/400/500/600/800/900/1000) and install it. It's very easy to do...just come on back if you're not sure how.
