So can someone compare and contrast this kernel with the latest perseus???

The perseus kernel seems to touch upon updated wacom drivers and LTE modem improvements. I never game on on my note 2 and only care about performance and maximum battery life and pen usage.

So... which would be better suited for me? These kernels both have 1800 cpu and -100mv undervolting am I to understand that correctly?

Yeah can someone give me an overview of the under-the-hood stuff for a droid noob? Thanks.

The author completely disregards that the US versions have some hardware changes to them and using the 7105 kernel image on this device can be potentially dangerous as the GPIO pins between the US versions and the international version are different and things like battery charging can break. There are several power and charging differences between the two. It's lucky that this is only the AT&T version as on other carriers it would also break sound and volume. Use at your own choice but it's not something to be recommended.

I'd also like to inform some would-be users on some facts about this work.

this extreme kernel is a beast but gave me a soft brick and had a very difficult time getting odin to push stock firmware through. It took me several hours of wiping and pushing wiping and pushing lmao and it finally took. I was on cleanrom lite v1 with the persuses kernel and it was a good stable fast combo with benchmarks around 6700. I never had that set up crash or reboot ever . I flashed this kernel on cleanrom and benchmarks went up to 7500 to 7900 lol. Crazy never seen the test fly so quickly. But kept rebooting and loosing data. Then I couldnt get it in recovery or download mode. It took me about 20 mins of pulling battery and trying to get it in recovery twrp. THANK GOD it finally came back to life. Man this android game is so fun lol. Hope I help someone like the author says becareful and dont come crying to him when you have to go back stock lolol:good::laugh:

Sorry Im tired the whole process took about 2 hours and 30 mins or so. It took me 20 mins to get it into download mode and when it was in download mode it wouldnt take the firmware . I just kept going back into recovery wiping and pulling battery and pushing odin. It finally past. Im Dead tired going to sleep sorry for typing errors :silly:

While you may have a point there (though you didn't provide hard evidence to support your "accusation"), it would actually be insanely great if you could make it out via PM instead of cluttering up the thread by throwing arguments back and forth. You'll just spare us reports (about the tone of the posts - you're actually on the borderline of badmouthing) and the trouble to clean up.

Thank you for your cooperation.

Well day 2 using extreme v1 and still not 1 issue!!! I've rebooted several times, played games, watched movies, charged and discharged.

I use a rooted stock tw on bell with all bs bloat removed!!! I've ran stability tests, and what ever other test you can think of and again not 1 issue!!!

So I must say THANK YOU AGAIN! :D

There is not an option. Its clocked at 533 in the kernel, however the thresholds are tweaked to bump the clock speed up faster. What are you doing that you need a faster GPU clock?

VSync is already maxed out at 59, so im not really sure why you need a faster clock. We can bump it to 640, however the gain is very minimal.

I am playing a rhythm game called osu!. The note 2 plays it at a phenomal 58.5fps which is very good for 4.5 star beatmaps but a constant fluent 60fps is needed for 5 star play. If the gpu can be overclocked just a little to do this it would be amazing. Thanks for your support guys!

Hey commenting off topic...i noticed in another thread that you were asking about the camera and what not on Dagr8's rom, did you have these problems with the stock Kernel that comes with the rom or did you flash perseus or this one straight away?

I thought it was the rom but when I switched to stock rom an applied this kernal it did the same thing so it has to be the kernal not rom.

    Note2Core Kernel for Galaxy Note II N7100 / N7105 (LTE)​

    I am posting this here because it works on our LTE notes, since they all use a Qualcomm modem. I am running I on my AT&T note with no issues. All credit goes to g.lewarne - I am just posting here to so he doesn't have to maintain 2 threads. See his original post here

    For the moment, exFAT formatted SD cards are NOT supported.

    About this kernel
    This kernel is built from pure Samsung GT-N7100 source, with modifications and tweaks to provide the best user experience in reliability, performance and stability. Built upon my experience firstly with NoteCore and then HydraCore for the original Note, as many of you know, I strive for the best

    There are 4 versions of each kernel, for the International LTE model GT-N7105.

    This kernel has all debuging removed - logcat, android log, kernel log, schedular log, etc etc all disabled. This is for performance reasons, so if you are a developer this kernel is probably not for you



    Kernel Versions
    There are three variants of the kernel for each device

    STANDARD (STD) - 1.6ghz FSync() enabled
    OVERCLOCK (OC) - 1.8ghz FSync() enabled
    EXTREME (EX) - 1.8ghz FSync() disabled
    ASYLUM (AS) - 1.920ghz FSync() disabled

    The standard version, has no modifications to the processor clocks or voltages and can be considered a direct replacement for the stock kernel, and with FSync() enabled is completely stable

    The OC kernel automatically scales up to 1.8ghz, with the proven voltages and stability from the perseus kernel (the same frequency table is used), and with FSync() enabled is completely stable

    The EX kernel also scales to 1.8ghz, and has FSync() disabled. It offers by far the best possible performance. In rare circumstances you must be aware that this can lead to data corruption and the need to wipe / reflash a rom back to the phone. 99% of people will have no issues with this, as it has been extensively tested and proven on my previous kernel, but the risk is there. Dont go moaning to me if you lose your data and haven't got a nandroid backup!

    The AS kernel is meant for the crazy ones. People who come from an asylum, those from the Note 1 know I am crazy, so this was meant for them. If there is a demand for the 7100 I will build that as well. I am not responsible if you are able to cook bacon on your device after running. It features up to a 1.920ghz over clock, and 640ghz on the GPU, it will go up, however for the moment we will run with 640. The phantom bug is that voltages cannot be set with SetCPU. Neither myself nor gavin know why. The code is spot on. So we don't get it. Lol. The source code is on github.com/glewarne



    Kernel Features
    - Built from official GT-N7100 sources
    - 1.6 / 1.8ghz auto scaling
    - Optimised VM memory settings, and global readahead
    - Auto-rooting of any rom when flashed, even stock
    - init.d script support
    - CPU Voltage support through 3rd party apps
    - Modified GPU DVFS utilisation steps for maximum GPU performance, far better than stock (this is NOT overclocking!)
    - No logging / debugging of any kind for higher performance
    - Decreased CPU frequency transition latency
    - CRC32 slicing-by-8 algorithm
    - SLUB allocator
    - PEGASUSQ governor (default, others available)
    - NOOP schedular, (default, others available)
    - +50mb more free ram compared to all other kernels
    - lots of other minor tweaks and changes
    - ODIN TAR and CWM ZIPS available for all versions
    - TouchWiz roms only



    Download - Current Version v1.00

    We are talking about this at the moment. I have a sprint kernel to test when I get home from vacation.

    Also new source code had been pushed, lots a small fixes. I'm running v3.01 at the moment :)

    They will be released to the masses soon.

    I understand that the developers are happy with where it is, but giving an option to change it would make everyone happy. Besides if you werent out to please at all you wouldn't be sharing such an amazing kernel with the public. I think it is more of a general request, or an I'd like to see, than a demand from people. You guys are doing great work keep it up no matter what route you take.

    Very compelling argument. This is the kind of stuff we look for for support.

    I'll get with gavin about. I cannot guarantee anything, however I will talk about it, only because of this comment.

    It already supports the 64 gig, just not exFAT format. Which is beyond me why people need a 64gig SD card in their PHONE.

    Me and gavin both don't use exFAT so its hard for us to test it.

    As for those who are wanting "MORE" from your device. I have a treat for you, hopefully by this weekend I will be releasing an "asylum edition" version of the kernel(compiled by myself), which will feature an OC up to 2.0 and GPU @ 733. I believe 733 is a sweet spot, there is no need for 800, it netted me about 1 fps better over 733, where 733 is about 6-7 frames faster than 640. I've been testing it, and there is no real significant battery drain.

    However the 2.0 clock on the CPU, I will say 80% of you wont be able to run. My phone runs it, all day long. Guess I got a super chip lol.
