So,
We've all got our Xooms, what are you experiences with each kernel, which one do you find the best? (and with what governors?)
Secondly, What are your UV values? Whats the best you've got when trying to undervolt?
Ive just got my Xoom (32gb, wifi, uk) and im just on the brink of experimenting with the undervolting, i searched but couldn't find a relevent topic.
So please, do post values, kernels and your experiences
ah okay, I thought this would be quite an important issue,
I've managed to get the xoom to handle 1.6 undervolting each state by 100mv
I am however having trouble getting both cores to stabilse at 1.6. Using os monitor I can see that only one core sticks, the other goes down to 300 mhz,.

I haven't fooled around with over/undervolting, but I like the oc gpu version of the Tachi kernel.
Zero problems and very smooth. I am very stable at 1504MGh

what you using for OC?
Setcpu or pimp my cpu or anything else.
Which governor you use?
I had lots of rebooting with setcpu especially after applying voltages.

I use CPU Master for oc and setting profiles. I do have the oc set on boot, because 1504 is my sweetspot and is stable.
Just installed Moray+tachi
Mobo player freezed few times,rest ok.
Edit: Trying "No frills" discarded Set Cpu for now.

No Frills is good, but I don't know if you can set profiles, which are good to save battery, control overheating, etc...
Hello all, I was just wondering if there is any way of increasing the voltage to Trinity kernels, without compiling it myself?
I read through some searches and it looked like that was the only way but I don't know how to compile a kernel... I just wish that I was allowed to raise voltage to my heart's content, since it appears to be the snappiest kernel I have tried but they are all too low voltage for my CPU which needs a bigger boost than most.
Thanks!

the only other way to get your voltage raised, without compiling the kernel yourself, is to ask morfic to build you a version with a slightly higher voltage.

Yeah... I don't think there's live voltage changing on trinity.
Yeah that's what I thought.
Is there any reason why Morfic doesn't like supporting the Proton App? Given the other enhancements he's made, it'd make it a really perfect kernel that'd be able to custome tune for any nexus out there... it must be hard for him to try and strike a balance between what his personal phone does, and what's best for everyone else

sorry for the noob question, since i can't post on the development thread yet, so i figure i'll try look for the answer here
i've installed the CM7 for fit and also the OC kernel along with it. my question is, what is a UV/GPU module for and how to use it? i've seen my friend's device also with CM7 (not galaxy fit) and there's an extra option in his cyanogenmod settings for UV. it says that it can save battery but make unstable performance. well CM7 in galaxy fit is currently still very battery consuming, i think i need this.
i've tried to install Myrt UnderVolt GUI but it says "unsupported kernel. cannot find undervolt table. click ok to exit". but i'm sure i've installed the kernel supporting UV and GPU module from here.
any suggestion? thx before

UV means under volt module and GPU means graphics processing unit the Kernel is modified to deliver extra performance and Overclock the stock frequency to 801(Till now) About battery and all I don't know if this saves battery(Since you are running your processor at higher speed then recommended)You're likely to finish your juice much faster
If you want to save battery than adjust the frequency to lower values an governor to power save or on demand Though I suggest you dont use the in built system settings to do so Use No-Frills
Just wondering in everybody else's experience which kernel they find to be the best as far as battery life and performance goes. I've only seen 3 kernels for 4.4.2 being leankernel dkp (I believe that's the name of it) and ktweaker. Also what settings you found to be the best for you (governors, undervolting settings, overclocking settings, Etc.) I do a lot of facebooking but that's about it. So I guess let the discussion begin? I'm running the latest update of cm11.
Kernel are fone depended. Wat works for some ppl might not work for othets. Try them all out let them run couple days then u can decide which is better for you.
BMS and KT747 also have 4.4 versions
Best is subjective. Here's my subjective approach, so caveat emptor, take what I say as personal belief and not a professional benchmark testing...
For AOSP-based roms, here's what my experience is:
Lean: Easiest and simplest of the kernels. Has limited governors, but the tweaked InteractiveX is pretty effective at doing what you need. It also has a crapton of S3 specific tweaks to improve battery life. You can overclock to 1.72 (I believe...) Downside? The min frequencies are 384k, which means other kernels can go into a deeper sleep. The TCP algorythms are limited too, so choose 'reno'.
DKP: I love this kernel, but several people report it doesn't work for them. This kernel has a ton of governors, with 'freelunch' and 'asswax' being the best. There are also a lot of TCP algorythms (choose 'yeah' for best performance). You can overclock to something ridiculous like 2.1... but I keep it at 1.62; there's also deep sleep frequencies down to 54k (yes... 54000), but I tend to stay at108k. The downside? Some people can't get this kernel to work on their device and it doesn't have some of the battery saving tweaks Lean does.
KT: This is kind of the 'go to' for many people, because it has a standalone app that flashes in the process and the dev is pretty active with the S3 version here. Many of the same features of the previous two, but different governors and nothing that's a device-specific tweak; the kernel is developed for multiple devices.
BMS: This, to me, is a similar kernel to KT and was my go-to for 4.3 roms. I haven't used it in a while, so I can't speak to if it offers more governors and customization.
My take and choice?
Lean and DKP offer the best battery and performance than the rest; they seem to give the same performance, so really you can use either and be happy. I find KT and BMS to be sluggish (even with tweaking) on 4.4 roms AND they don't seem to put the device into the sleep I want it to for battery savings.
BUT... If you're flashing Gummy, give the stock kernel a try! It's the only AOSP-based rom that doesn't use the Cyanogenmod kernel and you can actually get some good performance out of it. I flash DKP over Gummy, but I also flash Lean some times.

Anytime, man. I'm ADD when it comes to roms and kernels, so I'm constantly changing them, but I really like the DKP/Gummy combo. FYI, if you're going to flash Gummy, get the 1/15 build... it's the one I'm on and is the most stable as of late.
I also recommend using the TricksterMOD app from the Play Store. It allows you to modify every feature the kernel will allow and can set on reboot.
Let me know if you want to know what my settings are in Trickster... I have it pretty dialed-in to solid performance and battery life.
Oh and as flyest said... nandroid, THEN flash. You should probably wipe dalvik and cache too. You don't have to, but I've had some bootloops before when I didn't.

Don't even bother with the donation version... you can do everything you need with the free one.
As for I/O... you'll hear various claims that one is better than the other, but I stick with ROW. For the memory our device has 'Read Over Write' is the best scheduler you'll get with these kernels. FIOS is really the best, if you can find it, but ROW is what I stick with.
This may help clarify... or confuse you more lol http://timos.me/tm/wiki/ioscheduler

Here's only stuff I tweak.
SETTINGS:
TCP: 'yeah'
CPU FREQUENCY: min - 108000 / max - 1620000
GOVERNOR: freelunch
SPECIFIC:
Force Fast charge: YES.
Multicore Power Saving: 1
MPU Voltages: Press minus once for -25. Note that this may cause a 'wake lag' with the screen, so revert to 1150 @ the 1.512 frequency if you have issues.
I also tick the box for 'kernel settings' on reboot, so the app overrides other settings that are in effect @ boot.

In Trickster, TCP is at the very top of the 'Settings' window and should be a drop down menu.

I've always used Lean Kernel for touchwiz and aosp roms. Very battery friendly and over clockable. I also like DKP for touchwiz. DKP has TricksterMod support and I believe Lean Kernel does as well. But if the rom has performance in the settings menu of the rom I use that instead.
Thanks to beepea206... I'm now getting 20+ hours of battery life off of one charge... I'm not changing a thing
Hello
I am new to this forum and am a long time CM user which I am using on my phone at the moment. However, having discovered the aggressive thermal throttling on this phone (CPU-intensive tasks seem to throttle the max CPU speed down to 1190 MHz very very quickly, before the phone even gets warm), I'm trying to find a custom kernel that will work with CM. I don't care about any fancy features such as S2W or DT2W and if the kernel allows these to be disabled then that would be even better. Basically looking for a reliable, stable kernel that can be configured to be as close to stock as possible, but which would stop the aggressive thermal throttling.
Thanks
Hi, and Welcome!
I'm afraid that your post likely will be considered a "Best ROM or kernel" thread which is not allowed. It's usually suggested that you go over to the development forum and try out kernels for yourself because everybody's needs are different, and so on.

Hi,
Yes they are compatible too, for ElementalX choose the right version. Both have thermal settings.
There is also: http://forum.xda-developers.com/showthread.php?t=2649458 and http://forum.xda-developers.com/showthread.php?t=2633955 (almost the same kernels apart the Toolchain), compatible with CM/CM based rom with thermal control too.

All you do is make it "best kernel for specific criteria" then. Mods see it all as the same thing.
I'm giving ElementalX a try for now. The mods can feel free to close this thread if they see fit.
Thanks for all the replies.
before this gets locked you need a CAF kernel, Chaos kernel comes to mind, they do nice work. Comes with NXT tweaks which allows you to customize almost everything including temp.
I tried all possible CM11 kernels and Chaos kernel has in my opinion a very nice CPU load management.
Other kernels will stay for several seconds in max frequency after a power demand which result in higher CPU battery drain.
Bricked kernel was also excellent in that field and super responsive but the developer takes a break at the moment so the kernel is not usable for the CAF Version of CM after 25.01.14 without further modding and the AOSP mod for CM CAF is producing some weird behavior on my phone so I go for Chaos and CM at the moment.
I found Elemental would keep upping the minimum CPU to 1267 instead of 300, so at the moment I'm trying out NexXxt as @viking37 linked above, and using Trickster to configure the temps it seems to be working pretty good.

It's normal, it's how Mpdecision from Qualcomm works (for smoothness purpose). Each time you touch the screen the min CPU freq is increased to 1,26 Ghz. In fact the apps reads this at the min CPU freq because you touch the screen to open it. When you stop to touch the screen the min CPU freq will go back to 300 Mhz, the app needs to update the reading of the min CPU freq too but with Trickser Mod it seems it stuck at 1.26 Ghz all the time (for the reading only) but your min CPU freq is 300 Mhz when you don't touch the screen. You will see better this behavior with an app with "live reading CPU freq" like PerfMon or System Monitor.
You can use the "lock frequency" setting in Trickster Mod after set your min CPU freq to 300Mhz, if you want.
