i9023 OC Voltages

Hi all,
I tried lots of combinations to OC my i9023, without any results.
I currently have CM10.1 Nighly + Marmite 7.3.1, which actually seems to be the fastest combination for me.
Btw, if I try to OC to 1096 or 1320 it starts rebooting.
Everyone said me to raise voltage.
I'm using NSTools and it appears that Marmite 7.3.1 already has higher voltage for 1096Mhz and 1320Mhz.
Furthermore, there are two settings: ARM Voltage and Interal Voltage. Should I increase both of them?
Are there other people with 9023 which overclocked it succesfully? If yes, with which tool and voltage settings?
Thank you

I have my i9023 Nexus s OC to 1512Mhz STABLE.. no random reboots or something.. my battery goes easily one day even with lots of gaming.. I use NSTools.. (my snapshots are from SetCPU.. ;p )

With that voltage @1500 you will probably burn the cpu fast...i think. Maybe someone with better knowledge can advise you. But i wouldn't keep such a high voltage on my phone

It really seems too much high...
Btw, which ROM and Kernel are you using?

On marmite i've never been stable on OCs, even with raised voltages. On matr1x kernel you can do 1320mhz without raising voltages.

I am using Hellybean (the latest 26/2/13) and my kernel is Devils's kernel NOT the latest but the 21/12/12 release.. this kernel is my favorite.. try it out.. works on 4.1.x, 4.2.x.

I really don't care about burning my cpu. I have my photos backed up with dropbox.. and I'm on contract with my carrier so I will get it fixed within a week..

Is there an official thread/page for Hellybean and for the kernel?

There is a thread on XDA for the ROM Here.. For the kernel there is also a thread on XDA Here, but I don't think that you will find that specific version, just download it from my attachment above..

I have tried it and set it at 1320 (with LIVE OC 110%) and it seems stable.
Why do you suggest that particular version? Have you tried new versions and they are not stable?

I have tried all the new Devil kernels and they are stable for every day use but not as fast and battery save as the older version.. This is my opinion.. I have my nexus clocked at 1400Mhz and then apply 108% LiveOC witch took me to 1512.. Stable..! (at max arm volt 1500 mV)

[Q&A] Samsung Kernel

While we don't have any custom kernel as of yet, there are few apps that can change how the cpu behaves.
My findings are that the app kernel adiutor works the best for changing parameters.
Hopefully we can share experience with tweaks in this thread. I have been using cpu input boost at 1305 mhz and cpu sync freq at 1344. This to prevent fast jumps to 1401 mhz and 1190 mhz.
Have you ever noticed that if you boot the device with just wifi ticked in, the cpu0 rests at 300 mhz? (While the other cores are turned off.)
Enable mobile data and the idle state becomes 1190mhz.
There is a parameter that can be changed. However this parameter is soon changed by some unspecific process.
check it with
Code:
cat /sys/power/cpufreq_min_limit
Disabling qualcomm hotplug solution makes all the cores run at 300 mhz, is it bad for battery life?

Can you solve otg problem with making custom kernel?

Disable APP freq_min_limit Kernel for stok firmware

has anyone tried this kernel, does it work?

How do you do that? I'll test your kernel. please elaborate

I've created 2 custom kernels, one for cm11 and one for stock fom, give a look and try.

Is compiled from source, after making the necessary changes.

Yup I've been trying your stock kernel; you have implemented new governors, which are great.
I've been testing alucard and darkness since yesterday. They seem to both provide less high frequency spikes. But I will test more.

I've just tested your kernel and the freq_min_limit "problem" (or feature whatever it is) is solved.
Using mobile data, the cpu idles at 300MHZ, finally :good:
Why don't you two join forces and compile kernel with both your features? sev3n1985 's kernel with the disabled freq_min_limit. That would benefit a lot.
The next feature to include would be the quick charge. Thanks guys

Most battery friendly kernel

I've been using sev3n kernel for a couple days, but I wanted to know what is the most battery friendly kernel for the stock rom.
Thank you
Edit: I tried the configs that @ziad311 told me and they are great!! Check them out:
ziad311 said:
Yeah use kernel adiutor, min freq 300 max freq 1401
governor smartmax, cpu hothotplug disable mpdecidion and use msm hotplug, cfq I/O scheduler and disable fast usb charge
and there you go
and don't forget that battery life depends on your use

Here you go: https://www.mediafire.com/download/cau02wlc8874v26 (I'm using Linaro Kernel by Nick Verse).
What's the battery and cpu temperature? Check it with Kernel Adiutor.

I had those temperatures too. At this moment, my CPU is at 40 and battery 30.7. It may depend on the weather too.

Normal use.
I dont know how big was CPU temperature when was in idle, but if phone is not hot when is in idle, then is ok i guess.

Downclocking CPU

I am user who watches YouTube most of the time and I looked into BBS and CPU is running about 600 MHz at all 8 cores all the time when I watch videos. I guess thats a lot and it drains my battery. Is it somehow possible to set the lowest clock about 300 MHz when I am watching YouTube? Or just shutdown 4 cores at least? I guess I will need root for that. Thanks

As you can see, I was watching YT for about 4 hours and most of the time was CPU running at 653 MHz, not lower.

600 mhz is the lowest you can get with stock kernel
I believe some kernels (Extreme kernel / Project K) allow you to set it to 300 mhz

Great! But is it still possible somehow in stock kernel? With magisk and some kernel apps like kernel adiutor?

You need an custom kernel. However, the 300mhz is slightly too low. Making music laggy and distorted when turning off the display.

Nope. You need a custom kernel

Most of the devs are already getting rid of OC/UC on their kernels, F.Y.I

Instead of lowering your clock speed try disabling four cores and reduce the max frequency. Set governor to conservative. If you want more power saving use powersave. Warning: performance will degrade heavily.
Edit: skipped over your mention of disabling four cores. Still it's a valid choice. I do it in extreme case.

It's not needed for our Mi A1 i think...

We don't have big.LITTLE. because of 8 cores it shows two clusters of 4 cores as big and little.

What about hotplug.... Never see any core stop @Cpu-z... Rip battery

RIP battery what, the Snapdragon 625 is a very efficient chip. Most modern chips nowadays provide zero to negative impact on the battery life with active intensive core hotplugging.

This soc consumes almost nothing, not worth at all to downclock/downvolt.
