Back with another of my noob questions that is hard to find definitive answers to. Ok so I am running on a 1.4 kernal....is this good for the health of a phone? Now it seems the kernal side of development is really motoring....what can kernals offer ultimately to users? Thanks in advance
custom kernels mostly provide performance improvements. but sometimes they can also enable features that werent available with the stock kernel(for example... 720p video recording and fm radio in the nexus one)
Thanks I understand battery performance can be increased also?

absolutely!
A kernel with cpu undervolting could give better battery performance.
Excellent. Well the benchmarks don't lie and my phone certainly boots up quicker at 1.4. over or underclocked I look forward to more kernal flashings. Modding is a bit addictive
What I have here is a VERY BETA kernel built from the latest LeeDrOiD git with some ondemand tweaks to make it a bit more responsive, as well as AXI Scaling, an undervolted bottom end at 122mhz, and with a topend of 2016mhz.
Many phones may not run at the full upper-end, but vddsys is implemented as in the LeeDrOiD kernel, so you may increase or lower the VDD by 25 for 20160000mhz to attempt to get it working.
Currently working on getting a github page up with this source. I'm running it on the Unity rom at the moment without issue. 2016mhz should only be used for benchmarks, and not 24/7.
Two way call recording is also included, as well as a startup script to run at 1843mhz ondemand at startup.
Changelog:
June24-Initial Release...Working on Cleanup.
GitHub Page: https://github.com/synergydev
Will work on marking changes shortly. It should also be of note that because my GF's phone seems stable at [email protected], I changed the voltage at 2016 to 1.5 on the git just because it seems my phone likes high voltages.
I've tried 2000 a long time ago on my kernel, but my dhd couldn't handle it. and it handle very very low voltages, so didn't want to release a kernel with the freq that doesn't even work on dev's DHD I've even removed 1980mhz from my kernel because there really isn't any use of that freq rather than frying your DHD
I think that BuzzBumbleBee had 2000 on his kernel once, don't remember right
Good job BTW
edit:
wht is a working voltage on 2000?
I've trid up to 1.5V and it was unstable

I'm using 1.525V at 2016, however my DHD could never run the 1.9986 in your kernel without a voltage bump (could undervolt all the way up to 1.8 however though). In this kernel, I needed to up the AXI clock at 2016 to even get it to run, let alone benchmark continuously. I still haven't been able to get it to scale with a minimum under 300mhz.
This is why I recommend reducing the VDD at that speed by 25 if anyone's DHD can't run it.
In response to the first section, I only released this because I'm an enthusiast overclocker when it comes to my desktops (water chilled and vapour phase change cooled), and I wanted my clock to read the magical "2" at the beginning for bragging rights. With AXI clock scaling, we should be able to get slightly better battery life as well at the lower clocks (at least on the N1 it seems they were able to get better battery life with it).

+1 on that, but don't think you're more enthusiastic when talking about OC
We can argue about that the whole day
looking forward for your git!
I think 1.2G is enough..
@LorD ClockaN: if that's an sense kernel, you know what you have to do
Your 2016 MHz ASOP kernel coming soon?
with friendly greet
starbase64
You will find the 1.8GHz+ frequencies being only theoretical, with no increase in performance with respect to a "speed bump".
I have tested that a few months ago, going as high as 2.2GHz.
The maximum "real" performance boosts only go up to 1.5GHz (I clock my kernels to 1.497GHz).
Run a smartbench, and the results will speak for themselves.
Unless you want to fry your DHD?
Tryng with virtuous sense 3 and it makes lag the sense but for the rest is quiet good
Edit: after some time the lags disappears and all is perfect now

He said he's working on the github page to up his source soon.So I think it's already in progress.
Good job by the way mate.Never liked the fact that kernels with the vdd interface restrict us to 1500mV!

What do you need it for?
Just add frequencies in multiples of 19200 to arch/arm/mach-msm/acpuclock-7x30.c
If the newly added frequency locks, add the next multiple and/or up the voltage.
No magic there.

Raise min freq to higher[around 1.1GHz+] to prevent voltage spikes which might be causing the freezes, try decrease the distance b/t the 2GHz and the min.

echo 806400 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
On adb you have to change the min freq while booting up. 800 might work. Or use 1305600 [1.3GHz].
This is madness, yes i know people will post no this is sparta, but seriously, anything over 2ghz i personally wouldn't test

PMSL Benchmarks mean fuk all tbh do not reflect real world peformance running at 1.8/1.9ghz stuff like Playstation emulator etc run far much smoother and with no slowdowns etc... newbs and benchmarks lol!
I was wondering if any of you overclocked your device and why, did it help you and do you use it on daily basis? I was thinking to oc my phone but for me it seems that overclocking is pretty pointless.
I did over clock, ive also disabled two cores and left two overclocked. I now under clock slightly to save battery as lollipop is much faster so I don't need to over clock and if I use an aosp ROM there is little lag with good battery life. I think over clocking is pointless unless gaming and that's coming from an over clock addict lol.
It's pointless except if you're benchmarking.
During intensive tasks other than benchmarking, it's even more pointless, as it will hit thermal throttle/shutdown even faster.
Does it help with overall Ui smoothness and multitasking/app opening?

2.2GHz is already plenty enough. If it does not feel smooth then it's because your kernel's CPU governor doesn't make the CPU go up to 1.7GHz-2.2GHz enough. This is something you can tune yourself.

You mean 2.3? And it is very smooth but I'm just wondering if it will help me get more juice out of Cpu and make phone even faster [emoji14]

Same thing, 2256MHz is the only 2.2/2.3GHz step on the Nexus 5.
If it is already smooth, it won't make anything smoother, it will just use up battery.
The nexus speed is more than enough for me ?? , no need for overclocking
I have seen people report about 71k score in antutu. The maximum i have ever got is 68k with modified thermal configuration. Is there any other modification (kernel - wise or not) to be done so that I can get the maximum performance out of my mi4c?
Edit: Using miui.eu 6.1.28
They probably make a cold run with disabled thermal config to have better benchmark, not worth it...
sMiui is actually using the best thermal config for me, and i get 69k on first run, then results stabilize at 55k...
There is big (performance, smoothness, stability...) difference between stock miui (from en.miui.com) and custom miui roms?

Xiaomi.eu roms (on which sMiui roms are based) are debloated and optimized a little, so you can expect better performance, not great things, but is worth it...

Ok thanks a lot!
Any kernel settings tweaked?
I have installed a kernel and the application to support it (Kernel Adiutor). I want to know what CPU Governor i should use. I don't play games much just some small games with low graphics (bottle flip extreme). I don't want It lag like those old Samsung phones. It should be smooth.
I am currently on darkness.
I have given the screenshot of the CPU Governor available.
Wrong section!

I recommend the "Chill" governor or "Lionfish"

There is no way of saying... performance vs lag is trade off and the only way to know what works best for you would be to test them... I would start with one of the Intelliactive variants then Lionfish.

If you delete the kernel settings app? Generally yes.
