Hi i have one of those phones that wont boot at 710 standard kernel and i was wondering if someone would post an overclockable kernel that defaults to the standard 528. Thanks in advance to any sort of help
What?? Just flash a ROM that isnt OC'd.
can't you just set OC widget to not start at boot? I know there's a setting that mentions load at boot.

I think what he wants is an OC kernel that is overclockable but because his phone can't handle 710 (which most OC kernels default to) he'd like to start at 528 and see what he can push it up to.

Why don't you just use a OC widget and set the clock speed there?

Probably because he can't get his phone to load in the first place?
i am experimenting with this exact thing let me know what rom you plan on useing and i will see if i can work it out for you.
my phone will boot with the standard clock then it will work fine when it boots i just get the endless bootloop with kernels starting at 710
yeah mine doest that as well i have tried several different roms. has your phone ever gotten hot while useing it?
Yes it has i think if i find a kernel that defaults to 528 and you can use over clock widget to over clock it will boot all im looking for is the old kernel that they used to over clock with
working on it is my first time with mixing and matching a kernal to a ramdisk.
I appreciate the help

Modified a boot image with the lower default speed is possible, but it's involved adding the default clock in the init.heroc.rc in the Ramdisk of the boot image. There are many ROMs in this forum each has each own ramdisk. If you can decompile your current boot image, you add the 2 lines below to your init.heroc.rc under #power management
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 245000
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 537600
-You can use this (read this and install on your system): http://forum.xda-developers.com/showthread.php?t=633246#
That is a tool to cook your own basic ROM or use it to decompile the boot image, edit the ramdisk, recompile and sign your own flash zip.

currently im using blue echo 2.1.3 i would like to try the new version of that but i cant boot with their default kernel i would like one that will work with that and maybe one that will work with some of the new roms out that default to 710 thati havent seen yet
obviously you failed to read the post. its all linux stuff, to run on windows you have to use cygwin. so yes it runs on a mac

Ok Blue echo is fresh based so this should do the trick!

LOL I see i named it 547, but default is
245760-537600
Be sure and nandroid. I also removed the "on_demand" tag, i have had a suspicion that it may cause a problem with some phones. If you want to use on demand scaling, or any mhz higher than 537.6 use SETCPU to change it.
EDIT: Please let me know the result.
Is there any way to overclock X1 with android?
add acpuclock.oc_freq_khz=X to your cmdline, where X is the desired frequency in KHz. Works smooth for me with 640000, but ymmv

freeze. works at 639000 - its max to me
I'm using setcpu+setcpu.txt at SDcard and the value of the CPU to overclock higher than 639000 does not work. what to use to get the steping overclocking up to 691 or 710MHz?
or modify kernel to support overclocking up to 710!
who is able to.plz.thx
I can run on 691200Mz

in fact 595000 for me is unstable
"process no response" are frequently appears.
i'm running on 528000
ToT.... Orz....
I got mine running @ 633mhz, did not try higher yet.
Just set in in the startup.txt like the others said.
need overclocking higher 652MHz zImage for fully working on BareboneCM6.1 26-11-2010 !!!
clocking at 633 now... haven't tried higher.. works fine
for me it works stable at 670000 max.
the cpu clock widget says 653 though...
it must calculate 1MHz = 1024kHz, but why? those ain't no bits..
Cheers
cause the clock source is 19.200 MHz, so you get
(670000 / 19200) * 19200 == 652800 MHz
i overclocked it to 580 mhz. i dont see a difference. ill try with 600+
you note difference when you play games..like angry birds lite (the beta version) is very smoothly! yeaah!
i have neopeek cm6.0 29.11.2010 rom with 3d driver 29.11.2010 and the new kernel v4b.
i have setcpu and setcpu.txt
set profile: "turn off screen" with only 19 mhz and drained the battery 93% to 88% in 7 hours!! from 3am to 10am!! awesome!! with wifi on and sync too!!
My overclock use setcpu is not smooth for Angry Birds
I run the FRX3 Andriod.But only overclock is under 633Mhz.Up 633,like 652,Will be reooted the mobile.How can I overclock to 710Mhz???

Hi there !
Got my Optimus 2x yesterday, and played with it today
So here is a modified kernel compatible with MoDaCo roms. This kernel will boot with stock values (1000mhz max, default voltage). You can then enable higher states (1200, 1300mhz) with "Pimp My Cpu"! But you can also lower the voltage to get the best of your device Be sure to read the "Pimp My Cpu" post to understand how it work.
Try at your own risk ! May be unstable, i'm not responsable for any damage ... etc
Kernel developpers, you can find some informations on how all this work here.

14 Apr 2011 : 2x-kernel-2.6.32.9-fakeShmoo-cpasjuste.5.zip
I did successfully add 216 Mhz frequency to the kernel, but there's a bad news. I did found a hardware limit on the max8907 controller : voltages cant be lower than 770mV. It's why the stock LG kernel runs at 300 Mhz for it's minimal frequency, it run fine at 770mV. So this means that any undervolting lower then 770mV wont do anything, it will still run at 770mV...
Taking the previous discover in account, i didn't add the 216 Mhz state but replaced the (really) too hot 1300 Mhz state by a 1100 Mhz one, so you can probably use that without overvolting (unlike the 1200 Mhz state).
I probably fixed the non booting problem on some roms by adding the required "init.d" script in the zip update package.
MD5 : 514be18ced541f953cc15a1a0e995ea6
Be sure to REMOVE "boot settings" from "Pimp My Cpu" AND uninstall "Pimp My Cpu" before installing the kernel to reset default values.
12 Apr 2011 : 2x-kernel-2.6.32.9-fakeShmoo-cpasjuste.4.zip
A few fix on the oc/uv code which could improve stability
Now use an "unified" cpufreq sysfs devices name. I mean it use the same sysfs names than other oc/uv kernels (at least Galaxy i9000 ones). You HAVE to update "Pimp My Cpu" to version 2.1 at least for it to work.
Cpu sensor is now "/sys/devices/system/cpu/cpu0/cpufreq/cpu_temp"
Freq/voltage table is now "/sys/devices/system/cpu/cpu0/cpufreq/frequency_voltage_table" like other kernels. See this post for more informations.
Uv/mV table is now "/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table". See this post for more information.
Need Pimp My Cpu version 2.1 at least.
11 Apr 2011 : 2x-kernel-2.6.32.9-fakeShmoo-cpasjuste.3.zip
Back to "normal" releases (with more frequency steps added)
Lower 1200/1300 Mhz voltages, as nvidia recommand 100mV max voltage change between two steps. May not be stable for all.
Maybe fixed some bugs added by the OC/UV modification (some references to old freq/voltage table was still around)
Probably last kernel from me, dev's now have the necessary resources on my github to play around
Be sure to REMOVE "boot settings" from "Pimp My Cpu" AND uninstall "Pimp My Cpu" before installing the kernel to reset default values.
10 Apr 2011 : 2x-kernel-2.6.32.9-fakeShmoo-cpasjuste.2.zip
Test release, try to be as close as possible to the default LG kernel
Now based on new kernel sources released by LG instead paul sources
Only 6 available frequency like LG stock kernel (could prevent some problems)
Maybe fixed some bugs added by the OC/UV modification (some references to old freq/voltage table was still around)
Be sure to REMOVE "boot settings" from "Pimp My Cpu" AND uninstall "Pimp My Cpu" before installing the kernel to reset default values.
9 Apr 2011 : 2x-kernel-2.6.32.9-fakeShmoo-cpasjuste.1.zip
Added cpu sensor ( "/sys/devices/system/cpu/cpu0/cpufreq/FakeShmoo_cpu_temp" )
Added freq/voltage table ( "/sys/devices/system/cpu/cpu0/cpufreq/FakeShmoo_freq_voltage_table" ), see this post for more information.
Added uv/mv table ( "/sys/devices/system/cpu/cpu0/cpufreq/FakeShmoo_UV_mV_table" ), see this post for more information.
Changed unstable 1400Mhz frequency to 1300Mhz (we can't have more than 8 freqency)
Added "init.d" support to be 100% compatible with "Pimp My Cpu"
Be sure read the "Pimp My Cpu" changes which may interest you

Copy the zip to external SDCARD
Boot to ClockWorkMod Recovery (power button + volum down)
Choose install zip from sdcard
Select the zip
Recommendations
Nvidia tegra 2 (AP20) drivers as set the maximum allowed temperature to 60°, you should maybe not go further.
Nvidia tegra 2 (AP20) drivers recommend maximum voltages step of +-100mV (+-100mV between two frequency)
Cpu temperatures are already high without OC. After a lot of testing, i would not recommend to OC this device, but for sure undervolt it.

Very nice, looking forward to try it
Great, with some overvoltage it should run 1,5GHz possible you could make a update.zip?
Very nice indeed should get my optimus 2x this week OC-ed to 1.5 would be nice
That sounds good.

Negative, CPU-Info seems not to be able to detect two CPU-Cores. At my Device it shows 1998 MHz ... So it seems that with the Modaco Kernel both CPU-Cores are working
BTW. Great Work
I tried, but i stuck at boot too.
SetCPU shows 1998 BogoMips on Stock-ROM, so i guess it works there too.

I think this one is good without an update.zip at the moment.
As it rightly says in the OP this is for advanced users only, an update.zip will simply tempt everybody to have a go. In my opinion, until it's been tested a bit more it's best kept amongst the few.
Having said that, top shelf... 3105!
Hehe thanks for the support
Actually i'm unable to get a stable 1200mhz even with overvolting so maybe something else is happening. I'll try to have a stable 1200mhz before releasing a new update. I also got 1400hz but unstable too :
You can save battery and have great performance by undervolting/overclocking cpu and underclocking gpu, the best way i found is a script in rom toolbox.
i run on maverick 4.5 and try this day on 4.0
and this link :
http://rootzwiki.com/topic/14511-opptimizer-projekt-milestone-overclock-for-omap4-devices/
for me my values are:
for cpu
mpu_opps[3] rate=1200000000 opp_id=3 vsel=61 u_volt=1345000
mpu_opps[2] rate=800000000 opp_id=2 vsel=55 u_volt=1200000
mpu_opps[1] rate=600000000 opp_id=1 vsel=43 u_volt=1100000
mpu_opps[0] rate=300000000 opp_id=0 vsel=26 u_volt=1005000
for gpu
gpu_opps[1] rate=307200000 opp_id=1 u_volt=1125000
I started all the values with romtoolbox and create a script at boot
open rom toolbox / open tools / open scripter / then create new script
script name:
overclock
commands:
#su
echo 3 1200000000 1345000 > /proc/overclock/mpu_opps
save, and click on your new script and select "at boot"
re create a new script for the other values, for me a total of 5 script, 4 for the cpu and one for the gpu
The governor is mot_hotplug or boostedassV2.
I tried a lot of voltage values, the more stable are here for me.
I think this run on many rom, not only on maverick
The dev can implement this in rom ?

Try in terminal emulator (on rom toolbox or other)
To verify your value or your script after boot
#su
cat /proc/overclock/mpu_opps
To validate one value (for example)
#su
echo 3 1100000000 1360000 > /proc/overclock/mpu_opps
Then press enter

Backtrack is Suitable for our ACE and tested and reported working
Here is compatible devices Click Here
And use 480 Width - 320 Height Or 560 Width - 400 Height (If you need a wide view to the destktop)
Use Swap partition Min 64 mo and set swappiness to 60 (This swap partition used by Linux)
And the most important thing is that you need Min 2 GO Free on ur SD Card (Creat an IMG With 2G0)

Haha just try it man it is working and smooth I have Class 4 SD card and it runs faster ... Use Debian and GNOME as Gui and see by yourself I think the sound works too but if u use LXDE gui u will get no apps no hardware drivers LXDE can boot at 500 Mb .IMG file (it is just o try and it takes about 20 min with 912 kb/s to completely get installed...
Note: If you want better Graphics , scroll down in Linux Deploy app and Enter gui settings set 24 colors , DPI to 160 and Screen width always a little larger than screen height to get a real desktop on your ACE galaxy which can't run 'google chrome' yes it runs linux os like a charme !!!
For me I have no lag with those settings and select ARMV6L or lower in other linux distributions or just ARM if no V6L or J or 5 available.
I'm also facing the same problem on my Optimus G and still searching for solution
