I am using a custom kernel (ElementalX 0.10) but the the max frequency doesn't stick, only the minimum. If lock the phone and unlock, the only frequency that sticks is the minimum. Anyone with the same problem?

Which is the best setting to keep your setcpu for day to day use? Userspace? Performance? Conservative? On demand? Ineractive?
On demand probably.
Anybody else any suggestions
I use interactive... and screen off interactive..
Sent using SkyRadier 3.2 RC3 Incredible ROM with King Kernel #5 and the 2.15 Radio.
I kept stock myself, Min 245 Max 998 I believe, but here's a thread for this( n1 setcpu)
http://forum.xda-developers.com/showthread.php?t=618474
N1 running psfreedom recovery and MIUI! sent via XDA app =D
I have my set CPU to on demand.
But you should also enable profiles...
Such as "screen off" set to 245 for max and min that way when you lock the screen your saving the most power. Also for my own sake I set it for "battery<20% to be around 600 max and of course 245 min, just in case I'm low on power and need to conserve for some phone calls.
Hi,
Did someone has experiencied this fact:
Since i am under stock ics roms with cf kernels, when i try to set the cpu frequency, the setting is no longer effective, when the phone goes in sleep mode, when the screen is shutted off, or when the phone restart, the cpu frequency always return to 1.4 or 1.2 ghz, depending of energy mode selected.
I tried to use rom toolbox, voltage control, and system tuner to set max frequency at 1.0 ghz and none is really kept, the setting is effective but is canceled quickly as i said above...

Try speemod k3-9, goku, or notecore.
Hi,
I am new to this forum, professionally i am an embedded developer working on Atmel, PIC, TI based micro-controllers...
Been having this GT-I9000 from past few years now and its a excellent hardware....
Details:
Firmware Version : 2.3.6
BaseBand Version : I9000XXJW4
Kernel Version : 2.6.35.7 - I9000XXJW4-CL1043937 [email protected] #2
Build number : GINGERBREAD.XXJW4
I installed a small APP to monitor the frequency of the core on notification bar.... to see how much CPU gets used always, as response time is high for some app's
Through observation it seems it has 5 different clock modes... well this is quit understandable to save power
100 MHz --> 200 MHZ --> 400 MHz --> 800 MHZ --> 1000 MHz
But with today's APP more processing power is required, So I am wondering where I can tweak the current Kernel to stick with only 2 clock modes 200 MHZ & 1000 MHZ ??
I am not talking about overclocking here...
Any suggestion and steps to make it happen? Or better Kernel ?
Regards,
Vikas
You only want to use either 200 MHz or 1000 Mhz? Nothing in between?

It could be 100 MHZ --> 400 MHZ & 1 GHZ....
want to make the hardware resources available to APP & Android better at the cost of Power saving. Is it possible?

Yes it is possible but you need a different kernel. Upgrade your device to ICS or JB or KK and flash the Semaphore kernel (Mackay kernel is also a good option).
Then use the min max governor.
min max makes use of only minimum and maximum frequencies.
For more governors see here.

Thanks, but is it possible that i can keep Android Gingerbread on it and use the MAckey Or Semaphore Kernel? If yes ... where can i find suitable file, steps & instructions...
I have used ICS & JB on my phone after sometime of usage there are some problems with it... Wi-fi not working, hangs on call ... incoming call just makes the screen unresponsive...etc...
Although have not used KK ... don't know whether there is bug-free version of it ?
The min & max governor only sets the Minimum & Maximum Frequency to be used, which means 100 MHZ to 1 GHz, but does it mean that other governor modes will not use any in-between frequency set by Min & max?
If i want to set 400Mhz as 3rd frequency, how can i set via min & max?

Use this kernel if you want to keep Gingerbread.
Both ICS and JB are stable now so there are no bugs.
KK is still in beta so there might be some bugs. I still haven't come across any bugs though. It runs great on my I9000.
You can only choose one governor. If you want only min & max values (and nothing in between use min max) or if you want all the range of frequencies to be used choose another governor such as interactive (which is the best imo (for performance & stability).

Will the above Kernel Semaphore 2.7.4 support XXJW4?
Currently i rooted my I9000 (CF-Root-XX_OXA_JW4-v4.4-CWM3RFS) and running on a On-demand Governor (set the UP threshold to 25, so when in sleep low frequency and active always hits 1 GHz with most applications instantly)... seems to be good... but will try the new kernel if it is supported

Yes it works on XXJW4 but I suggest you to flash XXJVU. It might come in handy if you want to upgrade to a newer ROM later on.
Ive recently clean installed CM 11 and i expereince lag spikes once in a while.So i decided to change the performance settings of my phone. Could you reccommend a good max cpu speed/min cpu speed/CPU governor/I/o for speed and also battery saving .
Im curretly using ONDEMAND with max cpu speed at 1500hz ( the max value i have). Also will this affect my phone life and damage my phone by any way?

Stock kernels that come with custom ROMs are usually built for stability and some for battery life aswell so you can't really expect good performance from them.
Check mourta kernel out (the one I have link to in my signature).Flash it, I personally prefer to use 51 mhz min, 1.5 ghz max, ondemand governor, deadline i/o scheduler and I've set cpuquiet to userspace and hotplug is turned on.
Using this kernel with those settings, you'll get the best performance you can get out of your phone while keeping a good battery life.Since most kernels are slow to turn frequencies down or they do it in a way that causes lags.
You won't be able to change cpuquiet, hotplug settings until you get trickstermod.
We've got a 3.4 kernel made by mourta but it's vanilla (doesn't have some important patches etc.) but it should be complete in a few weeks.Better stick to 3.1.10 for the while
I recommend you to try mahdi rom, it's more stable than Cyanogenmod and iodak kernel is built-in.. http://forum.xda-developers.com/optimus-4x-hd/development/rom-mahdi-rom-2-7-unofficial-beta-t2867590
First you could flash the iodak kernel. Then you can overclock to 1700mhz. And use "performance" and "deadline" for the maximum.
Hope I helped you.
I have tried various custom kernels but they make the performance etc some stufff lag.
But with stock kernel limiting the max CPU frequency doesn't work.
It do shows the max frequency u set but CPU do runs at higher ones.
Any fix?
