[RESEARCH] Undervolting Club (POST YOUR STABLE RESULTS)

This club is for posting your stable undervolts
Please post MPU/IVA/CORE voltages
REQUIREMENTS:
- 1 MONTH stable
- 1 voltage value is allowed. You don't need to have all MPU voltages undervolted for this table for example.
SPREADSHEET: https://docs.google.com/spreadsheet/ccc?key=0AuqacKmGLKJ6dEdJZG5QTmNtQnoyYk0zbm5IanluMHc
Please post in format:
Stable since: DDMMMYYYY (eg: 23FEB2012)

The results will be taken into account and merged. I will use the results to undervolt the official CM10 kernel and I will commit these changes to become official.

CHANGELOG
CM 10.1 - v2.6 (14 OCT)
Ondemand and dynamic hotplug patches by stratosk
More RAM(790-791MB) (Experimental)
Remove some governors and IO schedulers (lean kernel)
Disable some debugging functions (lean kernel)
Linux 3.0.100
JB - v2.5 (27 JUL)
remove mpdecision
backport stratosk 's nexus 4 ondemand and dynamic hotplug
ondemand: touch_load increased to 1134Mhz for 1.3sec duration
ondemand: touch_load is applied only to CPUs the load is above 35%. So, CPUs with low load (and most probably unused) are not boosted.
These ondemand governor parameters are tunable in TricksterMod
Few patches to improve video overlay
Linux 3.0.87
JB - v2.4 (26 JUN)
"simple" GPU governor by faux123 + patch by franco
"simple" GPU governor set by default ( Currently only fauxclock shows/supports the correct option of simple governor )
Backport ondemand from CAF 3.4 kernel
Set SIO IO Scheduler by default (I did some benchmark tests and found out this is the fastest)
Update latest CM10.1 kernel source
Linux 3.0.83

Linux 3.0.80
JB - v2.1 (20 MAY)
tune some values(e.g. LCD voltage 3V->2.8V) according to leak 4.1 sourcecode
lower the max overclock freq to 1.83ghz
use original fix of stopping the bootanimation
Linux 3.0.79
Some patches & fixes ,check GITHUB for detail
JB - v2.0RC1 (9 MAY)

Limit MAX screen off freq = 702Mhz
Disable msm_mpdecision and use Auto Hotplug by _thalamus
Kernel -O2 optimization (thats why file size larger)

Logger driver update by stratosk
some misc backport,fixes
Linux 3.0.75
JB - v1.8 (15 APR)
BSODs from v1.7,v1.71 should be fixed
- Sorry for previous instable release and late coming v1.8
IO Scheduler: Add ROW
- As requested
CPU Governor: Set Ondemand(tweaked 2phase) as default
- By my observation, onedemand,badass seem to be more battery friendly due to shorter time in max freq.
Remove UKSM
- Cons>Pros
- if needed, Check stock KSM in Option - > Performance - > Memory Management
Revert CM screen off fix
- It seems disturbing wifi fix
- If you have screen off issue, reboot can fix temporarily. Or disable boot animation for permanently fix

Honestly, I dunno how init.d scripts execute automatically.
But you may use Smanager, select the script, click the "su" and "boot" and then "run"

Hi lyfkevin!
Have some question. What utils do you using for repack boot.img?
I tried different mkbootimg, unpackbootimg, mkbootfs, split_bootimg.pl but it not working. Using stock cmdline and base 0x40200000 but it not loading. I never have this problem before on my old phone. P930 have some specific?

I forgot where did i get this mkbootimg pack.
I followed this thread from HO!NO!
http://forum.xda-developers.com/showthread.php?t=1566202
And I use command to make boot.img
Code:
./mkbootimg --kernel zImage --ramdisk boot.img-ramdisk.gz --cmdline "vmalloc=450M,console=ttyDCC0,115200,n8 androidboot.hardware=i_skt" --base 0x40200000 --pagesize 2048 --ramdiskaddr 0x41a00000 -o testboot.img

Oh! Thanks! I never before not using --ramdiskaddr 0x41a00000

Made stuff for easy life. :fingers-crossed:
Just use extract.bat for extract and pack.bat for packing. Everything working automatic. If need change cmdline, edit make_boot

After installing it on last Miui 3.2.1 i have only 768 Mb RAM, why?

Thanks, I'm testing it now

cm10.1 wind kernel v1.0 released
not compatible to cm10, dun mess up
Currently CPU1 status is a bit weird, but defintely wont affect daily use. IT CAUSES LESS BATTERY DRAIN
I guess there is interference between kernel based mutlicore decision(msm_mpdecision) by show-p1984 and governor Intellidemand by faux123.
Test required.
My approaches:
1. switching cpu0 cpu1 governor
2. disable msm_mpdecision by "echo 0 > /sys/kernel/msm_mpdecision/conf/enabled"
3. try different mpdecision/intellidemand configurations by kernel tunner
4. terminal "su" "start mpdecision"
PLX dun hestitate to report ur feedback as it helps me to improve the kernel

Sounds like classic CM10.x

I want to say that after 8 hours as it remained 31 percent.
classic cm 10.x? (i don't understand)

I assumed you said it drained to 31% after 8 hours idle... if that's the case, classic battery hogging CM10.
If you meant it stayed at or near 31% after being idle for 8 hours, then Wow... That's pretty impressive.

yes, i mean it stayed at 31 for 8 hours (just idle, without wifi or internet connection).

How is screen off.
Will it reboot everytimes screening off
Voltage table for overclocking is depending on device chip.
You may have to tune it by any systools or editing init.qcom.post_boot.sh (simply +25mV for each step)

hey.well,kernel worked

Hi, @lyfkevin!
how can i OC GPU? Can you give me some detail?
I notice that GPU performance is not good as ICS stock rom

also u can use
fauxclock, kernel tuner etc.

thank you!
if i want to oc gpu frequency in 3d, i have to do some steps like:
adb shell
su
cat /proc/kmsg | grep 'echo 320000000 > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/max_gpuclk'
Right?

is it normal?
It is laggy in my end. Do I need to change something for it to fully work or what? I am new to using different kernels for phone so I am sorry.
It rebooted 1 time when downloading kernel tuner in playstore

Kernel works well and I am using it with tdmcode's aokp rom. It rebooted at 1st just after lockscreen appears but never again. I don' have any issues, its smooth.

My problem is that the kernel is not mounting my sd-card (64GB)
