[Q] Best kernel for MIUI

I am currently using MIUI 1.7.29 Osimood with the Tiamat 1.04 kernel, and I am wondering what the best kernel is for battery life. I am also using the V6 supercharger ram script. I am running my CPU at 960mHz at the moment, using the smartass governer. I also undervolted using vipermod, 960MHz at 950mV.
My choice consists of the latest Pershoot, UmaroKernel 1.06 or Tiamat 1.04
What differences would I see between those kernels, are they noticeable for a regular user?

Sorry man, but wehre do you find the vipermod for desire z? http://vipermod.tiamat-dev.com/faq.php it's not compatibile with desire z/g2....

Uh...what's wrong with the kernel it comes with? Can OC to 1.5GHz stock ya know. Battery life is great with it too. People always want to flash something weather it be a radio or a kernel.

Isn't flashing stuff and trying new things basicly the point of this whole site?

damn straight,
1) pershoot is a sense kernel? (i am proabably wrong but i have never tried this kernel)
2) umaro kernel i found had issues with wifi, high underclock freq (leading to poorer battery life), but fun if you have the time to tweak voltages and fast!
3) tiamat kernel i found had issues with sleep of death/random reboots on wakeup couldnt test it past that. (setcpu was set to screen off was: conservative 125min -345 max and would still crash)
if you are up for another kernel, i am now using this kernel (streamline5)
no voltage tweaking (pretweaked) but it has good batt, speedy and stable cant ask for much

Pershoot is actually for non-sense roms. The downfall people have with it is lack of governors. Some don't mind, some want variety. I've had great experiences with Pershoot's kernel and it's the baseline that all others are compared to (not to mention the foundation of almost ALL G2/DZ kernels).
Umaro's just needs to have voltage tweaks done manually but on the plus side - keeping the voltages normal (not UV) allows some people to reach higher OC speeds. It keeps the processor from bottoming out due to insufficient voltage which can easily happen when you UV. The main issue is with the Greased lightening governor - it's new and still a bit buggy.
Tiamat 1.0.4 is outstanding. I can sit all day at 2+ GHz (not literally, see: Chernobyl). I personally have an issue with the interactive governor but other than that it's my favorite kernel (Umaro may take that soon, once greased lightening is perfected).
Basically you just need to try out a few and see which you like. There is no 'best'. Most kernels will work with any ROM (Sense being the only exception).

Bumping a thread that is relevant to my interests.
It's about time for me to jump ship from an outdated CM ROM and try something new like a MIUI ROM.
With that said, I'd like to read more opinions & experiences from people using the various Kernels AND how the latest radio (the one released today) is working for them. I'm just trying to get the optimal experience here
Speaking of MIUI would anyone mind telling me some differences between OsiMood's ROM compared to the official MIUI-US ROM (or even DarkSpadez ROM)?
Thanks a ton guys!

I downloaded the official rom . . .then ignored it downloaded osimood and iv been using it since. Osimood is a lighter rom, which is always a good thing, unwanted languages etc are removed for a smaller faster rom. Also he preinstalls tweaks like an adblocker and extended settings mod.
Kernal wise iv been looking for the same info as you but couldn't find it. So I eneded up trying them all:
- Eugenes streamline5 is a nice kernal, preundervolted. Only probly is its not being updated so will become redundant.
-Tiamats kernal allows over clock to 2ghz and seems to support higher overclocks stably where other kernals can't. Except battery life has decreased with recent kernals
-Umarokernal this is the kernal iv come back to twice and am still on. It allows overclock to 1.9ghz and is kept updated by umaro. Performance per frequency seems as good if not better than most and osimoods miui runs smooth with this kernal on 800ghz with scarey governer (which saves battery) Another plus for me with this kernal is the scarey governer which for me definatly provides the best performance per battery ratio.

I'm currently running MIUI 1.8.5 with Eugene-Streamline 5 Kernel with the latest radio update Vision_Radio_12.57.60.25_26.10.04.12.
SetCPU with Governor ondemand provides me with better usage, power and responsive time then Smartass or Interactive.
OC to 1.2ghz
Battery life, about 30hrs with the regular 1350mah.

i just got 40 hours with similar setup but i use virtuous o/c daemon instead of setcpu
big fan of streamline5 and hope that it will get updated eventually

How do you get the virtuos o/c daemon?

Its basically like an automatic setcpu (which can't be changed on the fly) built into the rom, its in virtuous unity roms

What sleep profiles are you guys usein. I seem to have rebooting issues with any kernel I try unless I go to a sense rom. I've tried the vipermod now to see how it goes

But how do you get the virtuos O/C daemon to work on MIUI?

You can download it threw rom manager. Even with that kernel I get reboot issues. I assume its cause system ram isn't being cleard fast enough. I'm gonna try 100mv increase to see if there's a difference.

Undervolt gNex w/franco

I tried searching but didn't turn up anything..
I'm running AOKP milestone 4 and Franco'a kernel.
I'd like to undervolt it because I've got plenty of performance and undervolting did wonders for battery life on my old OG Droid.
I know I saw controls for the voltages the other day but I can't find them to save my life now.
Help?

SetCPU or Franco's Kernel Updater app
Sent from my Galaxy Nexus using Tapatalk

franco's kernel update and setcpu were the first place I looked but no love.
Didn't find anything promising in setcpu .
franco has a OC/UV tab which sounded promising but is only showing over clock stuff. the Calibrated Voltages tab sounded good too but seems to be read only for me (and I am su).
Also tried jrummy's Android Overclock. No joy there either.
I KNOW I saw it somewhere the other day!

your phone is rooted right?

Yep, rooted as soon as I got it.

I'm also running the same set up as you.
my voltage setting are located under :
Settings -> ROM Control -> Performance -> Voltage Control
Hope this helps

Curioser & curiuoser... ROM Control was the first place I looked today and is definitely where I think I saw it the other day.
But now I only have two sections under Performance: "SET CPU" and "FREE MEMORY".
The SET CPU section has "Max CPU", "Min CPU", "Scaling governor" and "Set at boot" but nothing about voltages.
I'm beginning to feel like I've fallen down a rabbit hole!

Did you mod anything? It should be located there...
Here is a screenshot of my performance menu, it's German but it figures
The menu points are Max CPU, Min CPU, Governor, Set on Boot and Voltage Control, running M4 and Franco...

i think voltages only show up if you're rooted and your kernel supports it.

Well he has written already that he is rooted and Franco Kernel deffo supports it...

But he might not. I thought was rooted one time before and ended up i wasn't. Others have done this before also.

Yes. Some versions of franco kernel disabled the undervolt feature. Make sure you flash the latest nightly (110 at the time of writing) and check the options in the franco updater app. You should see the Undervolt option.

Mystery solved!
V6 Supercharger was the culprit. This phone runs so well I probably don't need that anyway. Just ran it out of habit, I suppose.
Unfortunately I didn't notice this for a week and running the uninstall doesn't restore the voltage controls. I'll have to restore back to there and then redo all my changes for the past week manually. Oh well..

can i overclock cpu in cm9 ？

my friend's sgw overclock cpu to 1.6GHZ and he can play "amazing spider man" without some lag , so can i overclock in cm9?

yap that is. using it till 1,7 Ghz and smooth/stable

However, no game will run fluid if it already has major lags with the stock frequency.
Especially lags that are caused by memory management can not be fully compensated by raw CPU-power.
So for better gaming experience, other control levers might be more effective, like uninstalling apps with background activities or disabling home screen in-memory-lock, if enabled. Exceptionally, before starting huge games, cleaning RAM can also avoid some lags at the beginning, as you anticipate androids low memory killer methods this way.

What are your overclock settings?

What do you guys overclock your processor to on this phone? Back on my Galaxy S 4G I used SetCPU, so if that works on this phone too, what do you guys set it to, and why?
Cheers!

I think System Tuner is more popular now than SetCPU. I keep mine at 1.02Ghz to save battery life. If I really need major processing power I turn it up to 1.72Ghz using the Trinity Kernel.
With the new Trinity Kernel for the GS3 rooted running ICS UVALH2 I see Quadrant scores of 5800 and AnTuTu scores of 7800 - 8000.
Don't forget you need a custom kernel to overclock.

I set mine to 11.

You set what to "11"? What does that even mean? Pretty vague statement.

stock

I used setcpu to change clock speed & system tuner to control voltage,running at 810mhz with interactive+Cfq on SGS3 Rom+Faux kernel,with these settings my phone last over 10hrs with about 20-30% battery to spare & that's with heavy data usage

Best CPU Tweaking App/Optimal Settings

Hey so I was just wondering what everyone thinks the best CPU tweaking app is, and what you believe the optimal settings (such as speed, governor, and scheduler) are.
It's been a couple years since I've used an android device, but I've previously used SetCPU. Is that still the 'king' of CPU management or has some other app emerged?
In a nutshell, post your ROM/Kernel, favorite CPU tweaking app, favorite settings, and why you chose them.
Here's mine:
ROM: Stock
Kernel: Stock
App: SetCPU
Settings: 1512 MAX, 1026 MIN, ONDEMAND/CFQ
Why: Don't know any better options
Let's see what we can find out!

ROM: PA
Kernel: Faux
App: Fauxclock (trickster mod is a free one that works really really well)
Settings: 1512 Max, 160 Min, Intellidemand/Fiops
Why: PA so I can customize and faux cause I used his kernel for S3 and it gave me awesome battery life, and N7 is no exception to that! I went 1 day with 3 hour screen usage and only lost 35%.

ROM: ParanoidAndroid
Kernel: ElementalX
App: ElementalX uses Aroma installer to customize features
Settings: 1728 MAX, 1026 MIN, ONDEMAND I think
Why: Not sure what you expect me to say. These were the settings I used on my Nexus 7 before I returned it and ordered a new one from BestBuy. I plan on using the same setup when I get my new one.

..

These are my settings memory settings below
Carbon night lies

Kernel Tuner is a nice app for adjusting everything on your tablet. It allows you to adjust each core individually, or link them all together! I used SetCPU as my primary CPU tweaking tool for years, I guess since I first started flashing kernels on my OG Evo (Evo 4G, Wimax), but find Kernel Tuner to be much better!! Adjusting each core individually isn't something that SetCPU allows you to do, plus there are many other features in Kernel Tuner that aren't available in SetCPU. Ever since someone referred me to Kernel Tuner a while back, it's been my go-to CPU tool!! Anyone who hasn't used it before should DEFINITELY check it out, I think you'll like what you find in the app!!

im on elementalX 1.4 using trickster mod donate version, overclock at 1.8ghz but i under clock and undervolt with trickster app
if u don't play games, don't bother o/c, underlock to like 1.1ghz and improve battery life! i think 1.1 adds at least 1 hr SOT

Stock kernel isn't real customizable at all. You need a custom kernel. I recommend faux but everyone will say the one they use is the best so flash around use one for a couple days and move on until you find the one you like.

As far as I know, Faux plus the faux app are the only way to get the screen color balanced.
worth the price of admission right there.
And definitely turn your minimum clock down to the lowest it can be - idling at 1 ghz as you do at default is pretty pointless.
Add greenify and better battery stats to the mix to address apps that keep your device awake for no good reason, too.

"Faux123 Kernel Enhancement Pro" aka faux clock includes color tuning. Second or third to last page of the tunables in that app.
