    Trying to set up a SetCpu Profile on my phone.

    Moto droid with sapphire1.0 stock kernel(7×125-1000LV)

    any tips?

    also wondering how i should set max/min for the default mode.
    should i just leave it 125/1000 as it is?

    You could do that for default. To really take advantage of setcpu, set up profiles for sleep, charging, and temp thresholds.

    I thought having the cpu settings in the main menu meant there wasn't any point in installing setCPU?

    Is setCPU built into the ROM, or would it override the settings in ROM? Wondering how CPU scaling works.

    I prefer using SetCPU because it the profiles setting mode so cpu overclocks automatically in accordance to the profile settings.
    wanna know the 'suitable' Min/Max frequencies(speed) for my fone+ROM to set on each profiles(when charging, sleeping, etc) and also for default.
    I dont think SetCPU can override, so decided to disable the stock CPU control scaling.

    In order from highest priority:
    All ondemand

    Main 900 or 800/125 (I feel the performance diff between 800/900 and 1ghz to be negligible but the battery drain to be quite noticeable. idk my opinion)

    1. Screen off 125/125 (ppl complain about this but my phone wakes fine from calls)
    2. CPU Temp > 63.0C 550/125 (chip has rated threshold of 75C :D)
    3. Temp > 43C 550/125 (battery heats up slower and has lower threshold)
    4. Charging/Full 550/125 (I dont think this has much a difference because AFAIK 2.2 kernels automatically go to third slot when OC'ing which is 550)
    5. Battery < 21% 400/125 (I throttle down as battery gets low to buy some time)
    6. Battery < 41% 600/125 (same rationale as above)

    Hope this helps :)

    EDIT: This gets me about 7 hours of heavy use and more than 20 hours with light use.

    I believe SetCPU will override the ROM scaling limits.

    This is a good starting point and very close to what I recommend in my overclocking thread. I use a 1Ghz LV kernel and get 24 hours with no issues.

    yes, especially if you disable scaling in gem settings.

    appreciate it. just set my profiles same as above.
    also little bit concerned about the setting 125/125 for screen off cos iv found my phone lags when i try to answer the fone by scrolling the answer button.
    i dont no if that has something to do with cpu settings. it happend before and after the phone got rooted. i will give it a try though.
    never knew that chip threshold of 75C. good info.
    i think its really good settings for profiles! thank you!!

    I actually use 125/400 when in Sleep/Standby if I want to make sure there is very little lag waking up. I use 125/800 for no lag waking up.

    Not to mention I believe ive read that battery threshold is close to 50C in which case you'd want to start throttling down a little earlier (i.e 45C)

    Thanks ibebyi and skull one. I adjusted my profiles similar to what ibebyi posted. This is my first time playing with profiles since I have been feeling that battery life can be improved. And I've been hearing good things about Sapphire 1.0.0's battery life.

    Having taken a look at this I realized there is a problem with my settings. lets say the battery temp gets to 44 (not impossible) but is also under 20%. In this case it would go to 550 instead of 400 as the temp profile is of higher priority. So I think it should look like this:
    In other words, as you decrease the clock speed you should keep it higher in your priority queue. Have fun ;)

    thanks again for your info. just changed the priorities.
    i found my phone lagging a bit on waking up, such as showing black screen for like a second while the phone is ringing. well guess i can corp with that when i know that i am saving a lot of battery life. right? was considering set screen off to 800/125. thought its too much. what should i do on this? i mean i do wanna save battery life but also want my phone to run smoothly.
    also, just installed WaterMark theme and had my default on 125/800.
    it lagged a bit when i tried to open the main menu and in general. so increased the speed to 125/1000. worried about the battery not running long but seems to be fine. its probably due to the profile settings, i guess.
    do you think increasing it to 125/1000 will give a big damage on the battery life?

    FUNNY you should ask that question! LOL

    Do I have a post for you to read :)

    Sleep/Staby with 125/1000Mhz during a 20 minute period using ondemand and interactive governors

    You will see in the top part of the chart, that I ran your very question. The results were very surprising. Now this is only a 20 minute run but I bet when I do the 8 hour test later this week or next I get similar percentages.

    That may not help you. Basic tasks should not be lagging at 800 or 900 MHz. So this may not be the best kernel for your phone.

    If the lag doesn't stop, try another kernel! Believe it or not, there is a difference between using an 800 MHz kernel and using a 1.0 GHz kernel maxed out at 800.

    Every phone is different. Mine runs great with 1.0 GHz, but many tasks are actually snappier on the 800 MHz kernel!
