undervolt frequencies?

I just downloaded incredible control and am on doomkernel v6 and was wondering if anyone is running the phone with lower voltage setting than stock and still have the phone working.

Yeah, undervolting works nicely. Just gotta find the frequencies that are stable for you, because every device differs a bit

Roughly what are the frequencies

Well don't blame me if these don't work with your phone, but mine are
Speed : Voltage
122880 : 750
245760 : 800
368640 : 800
460800 : 875
576000 : 875
652800 : 875
768000 : 900
806400 : 900
921600 : 925
1024000 : 975
I don't like overclocking so I haven't tested much above 1GHZ
PS: Some may seem like they can go lower but start bugging out after a while

i noticed that undervolting seems to produce very little stuttering every now and then, but as for myself, i feel like battery gains a little more life, like maybe 3-4 hours. Still testing though thanks for your frequencies and yes, i know the fact that every phone seems to react differently but i wanted to check what other sexplayers are using.

Default Voltages

I forgot to back up my voltages and saved my new undervolted ones. Does anyone know the stock voltages? Thanks.

From SetCPU:
200 MHz = 950 mV
500 MHz = 975 mV
800 MHz = 1075 mV
1000 MHz = 1175 mV
1200 MHz = 1275 mV
1400 MHz = 1275 mV
1504 MHz = 1350 mV
1600 MHz = 1425 mV
1704 MHz = 1475 mV
I didn't modify any of the voltages.

Thanks a lot, exactly what I was looking for.

Also calkulin in his post has stock values flashable, you can get the file from his post or signature i cant remember

[Q] Default Voltages

Does anyone know the default voltages for each clock step for the Xperia Play? Or perhaps the maximum voltage it normally goes to on stock settings?
Am i right in assuming that the default voltages are different for the Zeus board in the Play than the board in the Arc?

MHZ Voltage(mV)
122 900
245 900
368 900
460 950
576 1000
652 1050
768 1050
806 1100
921 1150
1024 1200
Thats all for stock, programs that overclock have their own prefered vooltage for going further.

What would you give as an advisory as to not push the Xperia Play past? I'm currently at 1275 at 1.6Ghz.

I don't overclock mine. I like my battery life and the games I play don't need it.
I've pushed it to 1.5Ghz using SetCPU, but when I put it at 2Ghz, it crashed.

What V values to use when undervolting?

Hi,
I want to undervolt my Nexus. I just have no idea what initial values to set.
Could you please suggest Volt values for each frequency? Just to start with something.
I use franco kernel.
Thanks!

Thanks for your answers!
I wouldn't know what to do without all of you!

One good person posted his settings in another forum. I was using similar mV values for a while but a big bigger (by 50-100mV). So I lowered volts. And now it looks like this:
CPU -
1536 - 1275 mV
1420 - 1250 mV
1344 - 1200 mV
1228 - 900 mV
1036 - 875 mV
729 - 875 mV
384 - 825 mV
192 - 800mV
IVA -
266 - 900 mV
133 - 825 mV
Core -
512/384 - 775 mV
307 - 700 mV
153 - 675 mV

Stable. No problems so far.

Overclock my phone but cpu speed drops

Hi everyone. I recently tried to undervolt my note 2, I use nadia kernel, SetCPU and stability test v2.7.
I lock hotplug lock to make sure 4 core are running. And adjust the min and max cpu speed to 1704mhz and above, which are exceeding original cpu max speed (1600mhz), and run stability test. I notice the cpu speed is unstable and even drop down to 800mhz and doesn't raise up to the cpu speed I set.
I wonde if:
1. During stability test, is it normal if cpu speed automatically drop to 800mhz ane doesn't raise up again?
2. Is it normal? If my phone don't crash on the test but cpu speed drop, does it mean I shouldn't over clock to that speed?
3. Is there a solutions for the cpu speed dropping? I tried to restore voltage and use the default to run overclock test but CPU speed still dropping.
4. What's the cause of CPU speed drop?
That's all my question. Thank you for spending your time reading my post. Hopefully someone can solve my problem.
Than you very much!

Your cpu is overheating because to much vcore you dont need overclock in this cpu slow down... overclock is for professionals...

The most important thing after OC your phone is to UV the processor. Download trickster mode from the Play Store and swipe from the left edge of the screen and go to Specific. There you should find the voltages of the cpu which i will give to you for best performance after Oc(i score 25k+ on antut with those setups on 1920mhz)
CPU: 200 Mhz - 1800 Mhz ( Voltages over 1300 [email protected] Mhz makes a lot of heat and cpu throttles... )
1920 Mhz- 1350 mV
1800 Mhz - 1250 mV
1704 Mhz - 1225 mV
1600 Mhz - 1150 mV
1500 Mhz - 1125 mV
1400 Mhz - 1075 mV
1300 Mhz - 1025 mV
1200 Mhz - 1000 mV
1100 Mhz - 1000 mV
1000 Mhz - 975 mV
900 Mhz- 950 mV
800 Mhz - 925 mV
700 Mhz - 900 mV
600 Mhz - 875 mV
500 Mhz - 850 mV
400 Mhz - 825 mV
300 Mhz - 800 mV
200 Mhz - 775 mV
GPU: 160 Mhz - 533 Mhz ( Speeds over 533 are useless since making a lot of heat and also gpu throttles... )
160 Mhz - 825 mV
266 Mhz - 875 mV
350 Mhz - 950 mV
440 Mhz - 1000 mV
533 Mhz - 1025 mV
700 Mhz- 1100-1125(depends on the kernel cuz my phone crashes on devil with 1100 mV)
Credits go to @PROTOCHIP as i added only for 1920 Mhz and 700 for the GPU.
