I think we can post our own values of that kernel values, for finding a good measure for the best stability and less battery drain.
I think it's better to post only UV on stock frequencies; for making easier the comparison.
"Stable" means you have no reboots ever, you have to try for a long time and making an intense use of your CPU (there's an app called Stability Test, running it for 30 min is a very good measure of stability I think)
So, mine are:
300 - 830
600 - 900
800 - 1000
1000 - 1150
1200 - 1250
Mine are currently:
300 - 830
600 - 950
800 - 1050
1000 - 1100
1200 - 1200

Can anyone post their Voltage settings for Nemesis2all OTB OC kernal? Like posting ALL of them? Thankss.
You could skim through the thread starting at page 20 or so and look for lists of voltages and/or thumbnails.
I've been using this kernel recently. Here's my settings so far, although the overclocked settings have only been in place for a few hours, and I'm cautious about overvolting right now (this is my second fascinate ).
For reference, I had used comavolt before with no issues, but apparently barely (these settings aren't much of an improvement, other than overclocking of course).
I/O scheduler is set to cfq (sio gave me lockups in the market with comavolt settings). Enabled steps are 200, 400, 800, 1000, 1120, and 1200 MHz. I'm not bothering with 600 or 900 steps as I couldn't get any better voltage than with the 800 and 1000 steps. 1300 (and maybe even 1400) should be doable with overvolting, but doesn't stand a chance without it.
100-200 MHz: 850 mV
400 MHz: 975 mV
600-800 MHz: 1125 mV
900-1000 MHz: 1225 mV
1120 MHz: 1275 mV
1200 MHz: 1300 mV
I'm using the following 4 steps. You can swap in the last step for a 1500/~1400mV but I personally have yet to get that 1500 stable. At 1.4ghz I'm seeing 2000 in Quadrant, 20 mflops in Linpack. I'm also getting insanely efficient battery usage. Thank you Nemesis.
200 - 875mV
600 - 1150mV
1000 - 1250mV
1400 - 1350mV
*CFQ scheduler has kept 1400 crash free.
what are good setcpu settings? currently i have my main profile at 200-1000 ondemand, and i have 2 profiles: 200-200 conservative screen off, and 200-200 conservative temp>50c
as for the voltages i followed this
1600 MHz - 1425 mV
1400 MHz - 1250 mV
1200 MHz - 1150 mV
1000 MHz - 1050 mV
800 MHz - 950 mV
500 MHz - 850 mV
200 MHz - 800 mV
is there anything i should change for my profiles etc? my aim is to have the battery last as long as possible.
Not another thread for the same thing,

seems like you got a good CPU, cause mine cannot even set 200MHz voltage to 825mV
Kernel: Siyah Kernel v6 beta 4
Rom: Omega Rom v18
Highest Quadrant score: 5177 (Omega Rom v16.2)
Power Saving:

WARNING:
Setting 1500 MHz to 1600 MHz may cause your phone to crash.
Do not tick "set on boot" option just to be safe.
You have been warned.
My CPU's temp is ~ 49 degree when do nothing, but when i do something it will come to > 53 degree .
I flashed all Custom rom to find one can help my cpu temp is low but .. it still high.
This is hardware problem ?
I'm getting mid-30s when idle. I suggest trying another kernel.

Which ROM and which kernel are you using?
Also, undervolting will reduce temperatures substantially.
Im using CM9 beta-0.4.5.1-cm-9.0.0-RC0-olympus-UNOFFICIAL-signed.zip
Kernel 2.6.32.59-MB860-CM9-gf77ecf8
Jokersax
This kernel may doesnt support Voltages. Open SetCPU i not see Voltages tab.
Can u suggest me some other kernel ?
Try faux123's kernel, and then do some undervolting.
I changed to faux but when change some voltage setting then my phone hang and reboot many times. temp still so high ( i only set -50mhz). Any sugest ?
Try -25 and use profiles for screen off. Don't forget that there's a 100mV delta limit for each step. Are you overclocking your phone?
My current settings with faux123's kernel:
Screen off profile: 216 min - 456 max
Voltages:
1000 MHz - 950 mV
912 MHz - 900 mV
750 MHz - 800 mV
608 MHz - 700 mV
456 MHz - 600 mV
312 MHz - 500 mV
216 MHz - 400 mV
A note about undervolting: not every cpu is the same. You might be able to get an even lower undervolt, or you might not even be able to undervolt at all. Just make sure you uncheck "Set on Boot" until you get a 100% stable undervolt.
Edit: While you're at it, take a look at the "Time in State" info. What frequency does your phone spend most of its time at? If it spends a lot of time on higher frequencies, there's your culprit for high temps.

Which Faux kernel did you flash? You should be using the 1.0GHz kernel. If you are using that and have mild UV then you should have no heat (or battery life) issues. Also, you need to check for any apps which are causing your CPU to be continually under load when it should be at idle. This could also account for higher than normal heat.
Your phone should be able to handle -50 Hz at all frequencies, as that is a very low UV.

I flash Faux 1.0 GHz kernel (my old post) like u said. I will try all you suggest then report soon tks guys
I tried all you suggest but still automatic off (or idle cause i press power button my phone dont start ... it like my phone is hanging ) then I must off my battery to power on my phone.
The average temp around 44 degrees or higher ..
What ROM are you using, and did this problem occur on stock?
I'm using CM9 ICS
Sometime with stock rom, this problem appear. I think it from my phone's hardware. When CPU temp > 50 degree it happen.
Today,
after talk over skype,
view some webpage,
it's seem abit hot (about 45 degree).
After all, i lock screen then put to my trouser. When come to other place I open it, press power and nothing come to screen like its still running so i must off my battery to turn on again.
Flashed many rom from stock to custom but never see one can make me feel happy ). If it from hardware so poor me
Sounds like a hardware issue. Do you happen to use any type of case on your phone?
rieslav canopy
I dont use any case on my phone (sorry my bad english, "case" in your question mean protect item ? ).
I just found, when my phone is hot, it will shutdown.
Today when my battery < 15%. My phone suddenly running smoothly @@. I dont know why.
trying to find a way to help my phone run ok
Hi guys,
I'm currently using Resurrection Remix v2.6.1 ICS and am experiencing battery drain whilst using the phone. (I think it's okay when in deep sleep).
It was installed on a full-wipe so I was expecting good battery life - but it's dying like crazy.
I have a feeling its my voltages.
These are my current settings in SetCPU (I haven't touched it since I installed RR 2.6.1 but I'm wondering if these settings stay from times where I have mucked around ages ago)
Governor: CONSERVATIVE
Schedule: CFQ
1600 MHz: 1350 mV
1500 MHZ: 1325 mV
1400 MHz: 1250 mV
1300 MHz: 1225 mV
1200 MHz: 1200 mV
1100 MHz: 1150 mV
1000 MHz: 1100 mV
900 MHz: 1000 mV
800 MHz: 1000 mV
700 MHz: 975 mV
600 MHz: 950 mV
500 MHz: 925 mV
400 MHz: 925 mV
300 MHz: 925 mV
200 MHz: 900 mV
100 MHz: 875 mV
50 Mhz: 850 mV
Do these look alright? What can I change them to?
I'm looking for best battery life...I don't need it to be super fast....as long as I can run everything fine which is not that much..I'm happy

Are you actually using 1.2GHz and up? And 50MHz ?
Why mate? I mean your voltages look good. I would suggest using 100 or 200 to 1000MHz. And maybe different I/O sched. and maybe a different cpu gov.
Cheers

Your voltages look good. Try underclocking, changing CPU gov/IO Scheduler

Cheers guys.
It was initially set to:
200-1200MHz
Governor: Pegasus
I/O Sch: CFQ
I've changed it to:
100-1200MHz
Governor: Lulz-something
I/O Sch: SIO
Looks good so far but maybe it's a placebo reaction - will let you guys know
May I ask how crap is your battery that you claimed? It may be perfectly normal depending on your usage pattern. For stock battery, it might last only 3 hours playing Nova3 or 2 days minimal use picking up calls or sms.
Adjust gov setting to fit your usage or demand, turn down the brightness, or underclock the cpu will give you some obvious result.
Voltages on the other side play an insignificant role.

I don't think I do anything too much.
I mainly use it to check emails, Whatsapp, Facebook, Twitter.
Other than that it is just sitting there.
I have auto-sync on for Gmail, Enhanced Email - both on 'push' for email and calendars. Don't think that consumes too much battery though.
I forgot to mention that I also changed the under-clocking to -50 ... whatever that means
Install BetterBatteryStats and check for wakelocks, maybe some apps are preventing the cpu get into deep sleep. Alteratively download CPU spy from the play store to check deep sleep.

Don't think I have a problem entering deep sleep.
It's just that my battery is draining too much.
e.g. normal morning....
100% when I wake up
95% when I leave house
70-75% after I use my phone for 40-50 mins for the whole time on the train
At that usage rate it should be considered normal, since you need to get mobile data running and you're constantly moving. (affect signal strength)
If you wish to go further, you have to exchange with cpu performance, or otherwise get a bigger battery.
Downclock the cpu to 800/1000Mhz,
lulzactive inc load set to 80%,
sampling up/down 30000/40000
pump up/down 1/1
hotplug min_freq 400Mhz
gpu set to 100/160/200
up down thres 75 45 80 45
stay count 0 1 1
The above settings will pull some handbrake on ur cpu, but you should probably gain 10-15% extra battery life.
The result will be obvious for lightweight task, but it's likely to see same drain on higher load.
I know there's more than a few people on these boards who enjoy adjusting their voltages to fit their specific devices, so it'd probably be a good idea to have a thread that shared that info. Yes, each device might differ, but having reference points are useful to save time and see potential limits. This could also help devs. figure out safe regions common to all SGPs (though they seem to be close enough atm)
I don't know how much the SGP Int'l and US differ w/r/t voltages and battery, but I'll go ahead and make the assumption that it doesn't.
Anyway, I've been testing these values with (scaling) Stability Test between 30 cycles of all freq., followed by two 15 cycles of highs alone and lows alone. with no crashes so far:
[SGP 5.0 US: Paranoid Android 2.57 on Mercurius kernel]
1520 @ 1300 mV
1320 @ 1250 mV
1096 @ 1175 mV
800 @ 1025 mV
400 @ 950 mV
200 @ 850 mV
I've lowered the voltages for the highs to 1275 mV, 1200 mV, and 1150 mV, but ran only 23 error-free cycles before battery got too low to continue.
