Tegrak:

I have a feature request: Anyway we can do app specific profiles? For instance, for the games that really heat up the CPU and drain battery quick, I like to scale only to 1000 MHz or so. It would be great if Tegrak OC Ultimate could assign profiles to each app so that when the app is launched, the app would automatically set a (lowered/throttled) profile, and once the app closes, the default OC profile is reset.

Chainfire3D PRO allows for app specific driver settings, so I'm thinking this has to be possible with your OC app as well.

Many thanks!

Great idea, I was thinking the same this weekend. It would also be nice scale based on condition similar to SetCPU. Using the SetCPU you can say to scale the CPU back if temp is greater than 40 degree Celcius. Or set a profile when using the phone that min and max are 200 - 500 mhz. These features would be great to add to this application.

Yep, that would be great as a later add-on, but for now, app driven profile settings would be a great first step. I'm currently manually stepping down for the games that cause "excessive heat," would like that to be more automated.

Tegrak had said he doesn't like profiles. Also per app doesn't mean so much on a multi taking environment

You're clearly not understanding this request. Please try and understand what I'm asking for before responding:

1) Throttled/lower frequency makes a HUGE difference. In some games that overheat the SGS2 (especially at a OC'd max frequency), if I cap the highest frequency to only 800 MHz or 1000 Mhz, there is a huge reduction in heat output with no difference in performance. So your "multi tasking" bit is irrelevant.

2) Tegrak Ultimate already has profiles... just right now, you have to manually select them. I just want to see if Tegrak can assign them to only trigger per app like Chainfire3D Pro. So your "Tegrak doesn't like profiles" bit, also irrelevant.

cf3d is different because it redirects specific open gl calls per app. Cpu is different.

E.g lets imagine this function is working. i have feedr, text messaging, weather and facebook running in background to riptide in foreground. Which profile should tegrak use? I'd say riptide profile. Then i close riptide, what then? Default profile. The issue then is that tegrak will need to monitor for active apps at any time to detect which apps are running and prioritise the profile and he said he didnt want active cpu throttling to do that. If you can grab a moment and read back it is there somewhere.

You can always setup and pick your own profiles. Maybe a widget to set them manually is a better idea.

Chris

P.s. Less rude next time please

I'm not being rude, you're just being argumentative for the sake of argument. You're still not getting it: I already throttle the ENTIRE SYSTEM when I play a game that gets really hot (ie, Riptide)... the process is just manual. So, this doesn't need to be tied to the app as it is running real time, I just need it to throttle the entire system and revert to default OC upon open/close of a specific app. Yes, event based. This is not hard to do... in fact, if I had the source, I could probably do this rather easily.

Anyway, doesn't matter. I bought Tegrak Ultimate, I've asked for a feature add, and I'll wait for Tegrak's response.

I was wondering if there is any way in obtaining the ultimate version without going through the market (don't have credit card). I'd rather pay via paypal directly, is this possible ?

Tegrak. I cannot wait to get 5mv and 1mhz increments. :D Seriously, I would really like to have that for when I am at work with nothing to do but tune my clocks. Consider it please.

    Hello,

    After some day to day testing, here is what I think are the best methods to tune Tegrak Overclock :
    sorry for my poor english, I am french :)


    ADVICES
    • First of all, no matter how high your max frequency is, you have to put a low voltage @200Mhz. This is for battery life when your screen is off.
      You can try 800mV@200Mhz but on my device 825mV@200Mhz is 100% stable (I mean never EVER crash with no reason)
    • When your screen is on, most of the time (if using it), the frequency will be at max. So, if you plan on high frequency (like 1500+), your battery WILL drain faster.
      At high voltages (IE high frequencies), the difference is easily noticeable.
    • More than 1500Mhz is almost useless. The phone is already smooth at 1200-1300 and there are no lag at all. You will drain your battery for nothing more than your happiness to be at that frequency.
    • For games, prefer tweaking the max frequency of the GPU. Tegrak permit it, so use it ! It will be better for battery life when you are not playing games.
    • Don't forget to unlock your GPU freq after playing games like Asphalt 6. GPU drain more battery when locked at 267Mhz.
    • About Internal Voltage. I recommend to not scale it like Core Voltage because the difference between 850 and 1100mV is low on battery (I didn't notice a difference).
      For my device, I permit 25mV difference between each frequencies (950->1075). Also, it's easier to crash your phone at low frequencies.

    SETTINGS

    CPU Level 4 - 200 Mhz
    This is the critical setting of your phone because it will be most of the day at it (when your screen is off).
    No matter what are your other settings, I recommend 825mV but you can try 800mV. Most of the phones will crash at less.

    (Note : I have seen that if your max frequency is very high (1500+), it will be more difficult to put 825mV@200Mhz. I don't know why but on my phone, I had to put between 850 and 900mV when max frequency were more than 1500Mhz. If you are experiencing the same thing, please share !)

    Naphtaline recommends : 825mV@200Mhz



    CPU Level 3, 2 and 1 - 500, 800 and 1000 Mhz
    500, 800 and 1000 Mhz are frequencies who are used when you are using your smartphone normally : sending sms, using web browser, using home screen, etc.
    But, in fact, the max frequency is more often used.
    You can see that by yourself with a cpu frequency monitor (setcpu can do that). Just put your finger on the screen and you'll see that the frequency go max just for getting your finger position (like crypticc said, this is visible only for "on demand" governor).

    Anyway, theses frequencies are important because the phone will grind on them very often. So the voltage have to be low but not as accuracy as @200Mhz.

    With a calculator, you can scale the voltage on frequencies and then adjust for your device.

    Just remember that trying to put the lowest voltages on theses frequencies is pointless because you will increase your chance of crash.

    Naphtaline recommends : 900mV@500Mhz, 975mV@800Mhz and 1100mV@1000Mhz



    CPU Level 0 - 1200 Mhz and higher
    This CPU level is for overclocking. If you just want to stay at stock clock, you'll have to do the same as @200Mhz : As low as possible.

    So, there are three school for tuning here.

    School of battery life
    You want the best battery life no matter what the max frequency you can get.
    First, you have to find your lowest voltage @1200Mhz. Mine is 1200mV 100% stable (1175Mhz is ok but crashed one time on testings)
    Then, you can try to increase your frequency to find what is your max frequency for this voltage.
    As 1Mhz is nothing in performance, add 10Mhz every morning until you got a crash and go back to last frequency until it never crash anymore.

    For my device, it's 1200mV@1270Mhz.



    School of performance
    You want really noticeable better performance than stock and don't want your phone to overheat.
    In my opinion, 1500Mhz is the point.
    So, method is the same. Put 1500Mhz and try at 1350mV first. If it's okay after a day, try to lower the voltage 1325, 1300 (if your device is ok at less than 1300mV@1500Mhz, you got a gold CPU^^)
    When you got a crash, go back to last voltage until it never crash anymore.



    School of the biggest
    You want :
    - A kickass smartphone no matter battery consumption is AND no matter your cpu life will suffer
    - The best frequency your smartphone can beat

    Start by putting 1500mV at the Core Voltage. DO NOT try to do the same with Internal Voltage. 1100mV~1150mV is good.
    Next, try to start at 1700Mhz and increase by 100Mhz every hour. Between each test, do not keep your screen off. You can run a benchmark or playing games.
    Your phone will heat so be careful ! At this point, this is a little risky. You cpu may burn and die (I am not responsible blah blah...). Normally he can't (he will crash before) but who knows.
    When your phone crash, just go back to last frequency until it never crash anymore.
    Later, you can tune the frequency by steps of 10Mhz but well... Does it really matter ?

    I didn't tune a lot on this, but for my device, I can raise at 1500mV@1700Mhz with no errors.


    Naphtaline recommends : 1200mV@1250Mhz

    It has come to our attention that you have been asked to give access to the source code for your tegrak_overclock_galaxys_gingerbread.ko that is in your app. As this modual is covered under the GPL you are required to post the source code for this. IF you refuse to post the code for this modual (only one that needs to be posted) then you are breaking the GPL licence and I will be forced to move further on this.

    I got this message from zelendel, a moderator of xda.
    I don't have knowledge enough about GPL, so I didn't what he said.
    My job is a Windows programmer and I've never concern about the license except Microsoft Visual Studio and Windows.

    I'll start to study GPL deeply. then I'll open my source if I broke the rules.
    I think this post will be removed by him very soon.
    I'll send him links (that I posted) about this app.
    I'm sorry to developers who felt unpleasant by this thread like zelendel.

    Thanks to all for helping this thread.

    What is this?
    This is for family of Galaxy S devices and Galaxy S II devices.
    You can set maximum CPU frequency of your device on available models EASILY.
    This works with STOCK kernel, STOCK rom, (x)custom kernels and roms(x).
    You just need to rooting.

    (x) The latest kernel source of Galaxy S II on Samsung Opensource Release Center is not compatible with latest rom's kernel. So, this time, this app can't be used with kernels that built from source code.

    Ok, just ran the following through 20 minutes of stress test with Stability Test v1.5 (hammers both cores + memory simultaneously) with no failures. Max temp = 39C.

    Again, courtesy of Major_Sarcasm for his settings from Levels 1 ~ 4.

    CPU Level 0
    Frequency: 1308Mhz
    Core Voltage: 1225mV
    Internal Voltage: 1050mV

    CPU Level 1
    Frequency: 1000Mhz
    Core Voltage: 1150mV
    Internal Voltage: 1075mV

    CPU Level 2
    Frequency: 800Mhz
    Core Voltage: 1025mV
    Internal Voltage: 1050mV

    CPU Level 3
    Frequency: 500Mhz
    Core Voltage: 875mV
    Internal Voltage: 900mV

    CPU Level 4
    Frequency: 200Mhz
    Core Voltage: 850mV
    Internal Voltage: 875mV

    ===============================

    Could I have squeezed more out of the frequency at Level 0? Probably, but I got the phone to crash after 12 minutes with 1 notch lower on the voltage (-25) at 1308MHz, so I figured for ensured stability, 1308 at the current voltage will do.

    Could I have undervolted more on the other frequencies? Probably so as well, but that would take a whole lot of testing one parameter at a time, and I just can't be bothered. At the current settings, phone is going to and coming out of sleep, syncing up to my car's bluetooth with screen off, etc with no issues. So, it's good to go. :)

    Again, like I mentioned above, my goal is complete stability with a small overclock + some undervolting. Increased performance + lower temps sound like a win-win to me.

    Hope this helps. :)

    ok I have tried some UV settings and tested the settings with Quadrant and played Tekken 3 (FPse)

    I only use 1GHz max so I have not touched 1.2GHz or more UV settings, CV=Core Voltage, IV=Internal Voltage

    1GHz: CV:1125mV,IV:1075mV
    800MHz: CV:950mV,IV:1050mV
    500MHz: CV:875mV,IV:975mV
    200MHz: CV:800mV,IV:925mV

    These settings seems to work good atm, I think I can lower some more, but I will try these settings for a couple of days and see... btw, what is Internal Voltage?

    Hi Tegrak, what about setting I/O scheduler setting in next version... I managed to get 5200 in quadrant ay only 1280 MHz using deadline scheduler (400 points more than default cfq)
