I see the latest kernel's are talking about under volting could anyone give me some guidance on this. I have no idea about what voltage is safe or appropriate. is there dangers involved?
Thanks

undervolting is just lowering the amount of voltage used for a specific frequency. you can use pimp my cpu to undervolt each frequency to get the best voltage suited for your transformer.

Now that we have a new way to overclock in v14 there are near unlimited variables to overclocking with this kernel. I've found a good balance of performance with 1300ghz step and live OC value of 121%. Let us know what has worked for you. You may include voltages as well.
I'm using reborn90's settings
200-1000; 110% live oc arm volt; 800/950/1100/1175 int volt; 1000/1000/1000/1025
Seems rather steady, I also recommend turning save on boot in settings of nstools before applying these settings just in case xD

I am on 100-1300 with 116% Live OC, haven't played with voltage yet but everything runs great.
I can't seem to get any live OC percentage stable and anything around 118% + automatically freezes and reboots.any suggestions?

Do you UV first then live oc? Or is it just stock voltages?
Sent from my SCH-I500 using xda premium
For the most part I just use stock voltages when playing around with live OC because I haven't found any voltages in threads that i'm sure are stable.

it depends on how far you phone can go, some can oc more then others but some less then others, I usually never go passed 1.2ghz ,I'd rather save battery.

Just my opinion, but since Android 4.0 relies so heavily on the hardware rendering capabilities of the phone you'd be better off to UNDERCLOCK the CPU to 800mHz, and apply the Live OC to say 125% and have an effective CPU speed of 1000mHz while increasing the GPU clock by the same amount. I've tried it and it works very well but I didn't stick with it long enough to see how it affected battery life. You will need to modify your voltages though. I was at 1250mV on the 800mHz step.
If anyone is interested in just using stock settings, i found this thread interesting:
http://forum.xda-developers.com/showthread.php?t=1424064
100-800 mhz, 125% live oc.
So how much of a change have you noticed from Stock kernel to Glitch. I tried OCing once.. and it froze.. and phone died.. and ended up having to wipe / re-flash. Probably user error though
Just wanted to say I accidentally OC'd to 1.4ghz with 110% LOC and man did this thing fly and didn't even crash.

I noticed I'm able to achieve higher stable oc (over 1500) using low leakage voltage and live oc of 116 or less. Without low leakage i can barely acheive 1400 oc at anything over 110 live oc. Never noticed this much difference in internal voltage stability in previous kernel version. I wonder what's changed?
Hello guys,
I'm here to ask for all of your opinions about the cpu Profiles, frequencies and governor.
For screen on I'm currently using 1200mHz on performance, I would like to know if it would save more battery by using on demand governor.
Some months ago I had a discussion with few xda members about this subject. But that was on aurora v4. Now I'm currently on v5 u17. Let me know your opinion. Thanks

To be honest, I've never experienced any benefits of setting cpu profiles for screen on, screen off etc. Your phone will work much more smoothly if you stick as close to the defaults as possible.
I don't use profiles. My min is 245 and max 1200, using on demand governor.
For a while I experimented with profiles, and had bad lag when unlocking the phone, and terrible battery use when screen on.
Independent of profiles, your governor will put your phone into deep sleep when the screen is off anyway.
Do a search for "race to idle" this explains in more detail the benefits of using ondemand as opposed to other governors in terms of battery use etc.
IMHO, Android as a platform would be far better served if people stuck close to the default settings and cpu profiles. Most of the time, any negligible benefits are just placebo.

So according to the race to idle running with performance governor saves battery
Sent from my U8800 using xda app-developers app
In theory yes, but if your cpu is always running at max frequency, ie even when doing nothing, then no.
I have done tests, and my battery always lasts longer using ondemand as opposed to performance, or other governors.

Use interactive/bfq that's the best in my opinion

I read threads but did not understand, the kernel that have undervolting, after flashing is necessarily change the voltage or it comes pre configured ?
This for example: http://forum.xda-developers.com/showthread.php?t=2048739
Thanks !

Honestly, it depends on the dev. I mean with franco voltage comes stock, meaning it's values haven't been changed from stock. It's up to you to set them to whatever level you desire. Some devs make -100 uv THEIR stock....which is -100 from stock....hope this helps lol

I've seen a few post on how to undervolt but I'm still not 100% sure how or if I should, I'm guessing it gives a little bit more battery life ? Also what app would be the best to use ? And the best values to apply

you have to install custom kernel for undervolting.. and it does not give you battery life..it reduces how hot your phone gets..
It can increase battery life actually, not hugely but ARM processors used in phones use a few watts, wattage is calculated as voltage * amperage, less volts going through the lower the wattage, ergo lower power consumption resulting in extended battery life. /rant
OP you will need a kernel that supports UV (pretty much all non stock) and a UV interface, I prefer trickster mod. Look for core voltage and knock it down a step (-25mV). Then stress test / benchmark, if you don't freeze / reboot then you can knock another 25mV off, keep doing this until you get the minimum voltage your phone remains stable (for me 1025mV @ 1.5GHz). You can then set for the options to stick on boot.

Just curious what everybody is setting their cpu minimum frequencies at. I am not too concerned with battery life so I was thinking of setting mine a little higher to keep everything as smooth as possible. Is there a risk to raising the minimum frequency?

I think you would benefit more from choosing another governor instead Try intellidemand or interactive := Both of these should be better than ondemand

i have mine set at 300000 so when my phone goes into deep sleep it's using little cpu power, but i also have interactive governor so that when i turn the screen on there's no delay and the kernel and cpu have what they need to be snappy.
this thread tells you all you need to know about governors and i/o schedulers.
