    Thanks in no small part to rbheromax, we now have a working overclocked kernel with 10 governors to choose from. This thread is the place for all discussion related to overclocking the Victory, and which governors give you the best performance to battery-life ratio.

    What is overclocking?
    Your phone has a CPU in it (basically a computer), and it is set to run at a maximum speed of 1.2ghz. The interesting thing about CPUs is that the manufacturing process leaves a lot of errors in every single chip. This doesn't mean the chips won't work, it only means they cannot always work to their maximum design efficiency. So how do manufacturers sell chips with errors in them and not have them all returned by consumers? They do it by under-clocking the CPU's speed. This allows the chip to use less of it's own physical resources, avoiding bad sectors on the chip, and working around errors. They do this for entire batches of chips, even though each chip has different errors in different places. What this means to us is that there is potential to overclock every single chip out there, and gain better performance as a result.

    What are the drawbacks to overclocking?
    Pushing your phone to a higher limit that the manufacturers set it to has the potential to cause you issues. These issue range from kernel panic causing a freeze or reboot, to actually damaging the processor or other internal components. It takes a bit of time testing your settings to find the sweet spot for your CPU, just like humans they are all different to some degree. Note- some chips will overclock better/higher than others, that's just the luck of the draw!

    What is a governor?
    The governor is a small program (usually less than 1,500 lines of code), that controls the clock speed (and sometimes the voltage) of the CPU. When your phone begins to do something that takes up all the processing power it has at a particular speed, the governor will speed it up. When your phone is idle and doesn't need to be running fast to maintain everything, the governor will slow it down. The main advantage is battery life, the secondary advantage is chip life (since slower speeds mean less heat generated, hence a longer life for the chip).

    How do I control the overclock and governors?
    There are several apps in the Play Store that will allow you to set your clock speed, and in some cases your voltages. While I don't recommend it over other apps, I personally use No-frills CPU Control. Be warned that some of these apps could play havock with your phone, so ALWAYS BACKUP BEFORE TESTING!

    I have been very busy getting overclocking working on the Victory, and have not had much time to test out each governor and/or which clock speeds are best. Please post your thoughts, opinions, and settings for the best combination of preformance and battery life. Together we can find the optimal settings for our Victories!

    To find the highest stable clock speed your phone can support, set it high and then do something very intensive (games are great for testing stability). If your phone crashes, then back down the max speed by one notch and test the same way again. Once you find a speed that doesn't crash, back it down one more notch, and you should be stable. Note- Antutu has a stability test that can show you how smoothly each governor/clock-speed is performing.

    So post questions, comments, tips and tricks, and together we will get the most out of the Victory!

    Do you think we'll get something that gives us like 1.7 ghz? Your new kernel is great by the way. Also what is planned for the future of vaevictus?

    I'm posting a 1.8ghz overclocked version right now, in a new thread, kinda posted out of order, meh. Let's keep questions other than overclocking and kernel issues in the VaeVictus thread, and keep this one for discussions about overclocking. ;)

    Still experimenting, but so far conservative works the best for me. No browser, keyboard or ui lag. Lose ~7% battery/hour browsing the web normally through wifi, minimum brightness. Power save mode seems to knock the max freq from 1.8 to 1.2. According to no-frills, my cpu spends 1/3 of the time idle, 1/3 clocked at 1.2, and 1/3 scaled somewhere in between. Battery stats are with PSmode on.

    Powersaver makes my PSX emulator lag horribly, so it's out.

    Performance gives me a 12721 in Antutu, which is so far the best score I've seen on this phone, but the battery heats up.

    I really wanted to post this morning, but had to run off to teach my class... now that I'm on lunch I thought I would add 2 important points to the discussion here.

    First Battery life and drain percentages. I have found a surprising amount of ignorance (not on the forum, but just in general) when it comes to Li-ion batteries, and people still treating them like they are Ni-Cad... so just a few quick points for testing purposes and ensuring the data we get is as reliable as possible.
    1. Li-ion batteries tend to drain the FASTEST BETWEEN 100%-80%, and from 20%-0%... this may be an aha moment for those of you that didn't know this. That's why it drains so fast right after charging, or once it starts "dying"...
    2. Try to compare with your own phone, and the same battery. Try to use the same percentage ranges when possible (or just try to always test in the optimal drain range of 21-79%). Keep as many factors controlled and equal as you can if you want to get good results.
    3. Try to be consistent with battery temp as well. A hotter battery will drain faster! So a test in an Air Conditioned room, and a test done in a hot car are not equal!
    4. This one has nothing to do with testing, but is worth mentioning in case you don't know... you don't have to drain your Li-ion battery before charging it. Charge it whenever you can charge it (unless you are testing battery drain, like we are here). These batteries are designed to be topped off, and don't use up a full charge cycle by topping it off, so don't worry about shortening battery life.

    Now onto Governor related info... I found this great post with a nice list of governors and what they are supposed to do. You might find it good reading if you are wondering what the differences are between the governors (in laymans terms anyways).

    Li ions should, ideally, never go below 50%. Ask anyone who has had an iPhone 4 turn into a bag of popcorn.

    I get consistent readings on this phone, anywhere from 100% down to 30. Never let it get below 30%. Actually takes 30mins of heavy use to go from 100% to 99%. After that it's stable.

    Reset my no-frills stats 12 hours ago.

    Since then, with conservative governor, Powersave mode off, 55% of the time @ 384mhz (idle); 23% of the time at 1.8; the other 22% of the time between the two, evenly spread 1-2% per clock interval.

    Sounds about perfect for a governor; power when you need it, idle when you dont.

    Sup. Just got this phone today, coming from the Evo V 4G. Running this kernel with stock rooted room at 1.512/384 interactive/noop, it's lightning, but this phone is anyways compared to the evo. Good stuff! Thanks!

    Since installing VaeVictus Kernel I have experienced random discoloration in widgets and app icons, within texts, videos and more. This is a result of Kernel. I reinstalled RedSpot's Kernel and everything goes back to normal. Is there a fix for this or is anyone else experiencing this issue. Again the issue is with the Kernel not the Rom itself.

    This happened to me as well. I had power save on when I flashed and as soon as I turned it off out started bugging out. I flashed the backup and it went back to normal.

    Um and no one thought to say this earlier?!?!? Its a voltage issue. Ima fix that ASAP.

    never happened to me, I've had 0 issues.

    It hasn't happened to me. Also, conservative wasn't so conservative when it came to clock speeds, ondemand used much lower clock speeds. I'm testing smartassv2 now

    rbheromax Android Expert

    Well Ima go off on a limb and say 1.62 and 1.7 are the borked freqs. Up to 1.5 are correct as they are stock and 1.8 is on par with other board types...

    I haven't experienced any problems on Conservative or Powersave.

    I'm trying to test each governor for a full day. Not much point in testing for less IMHO. ;)

    Those are stock govs so they'll work fine, u need to test the ones that were added....
    When I get home (tomorrow) ima push some I/os to master unless u beat me to it :p

    Well this just happened within the last two hours. I spent a while trying to find the cause
  21. rbheromax

    rbheromax Android Expert

    Well we'll fix it soon... so any limitating govs lag ur phone I guess. I think because most of them default to 48x mhz no matter what u put it at...(power save, conservative, lagfree, etc)

    I had my phone on badass for most of the day until my phone shut off in my pocket. It reapplied on demand after I rebooted, since it had crashed. Then it crashed again about an hour later while in my pocket again.

    After that it was fine the rest of the night. Was out and about partying tonight so wasnt able to troubleshoot.

    edit: I'm fully updated btw, and was also in power saving mode in the options.

    Okay so basically minor stability errors. Debugging will be fun :)

    I won't be adding much to this thread (I am not a super heavy user) other than thanking everyone for adding their experiences. There is already a ton of info in this thread and it's only been around for a short time. The link to the "Governors Explained" thread over at the XDA Forums really helped me decide what governor I would like to try myself. Plus it explains what the "Scheduler" does. Highly informative!!!

    The fact it was in my pocket might be the big clue. Now that I'm rested up it seems like a pretty big clue, might have just shut off from heat (since it was in my pocket). I might try testing some lower voltages. What would I need to edit to change the voltages? I have some time this weekend to play around with it and report back.
