I read threads but did not understand, the kernel that have undervolting, after flashing is necessarily change the voltage or it comes pre configured ?

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 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.
Sent from my SCH-I500 using xda premium
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.
Sent from my ICS Mesmerize
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?
What do you guys use to monitor and control the voltage of your cpus of your nexus 4 after flashing the Franco kernel?

Oh I thought I heard you could change the voltages with Franco kernel so I kept trying to see which apps work but found none thanks though what's limiting the nexus 4? Is there any other way to under volt?

Franco personally is not a fan of undervolting. He'll probably make sure the kernel is stable before he adds the undervolting feature. There's been a lot of ironing out going on with the kernel and adding undervolting capabilities would probably cause more trouble if its implemented now.

K guys.. I am not sure if its 4.3 or something else.. Can someone confirm.. I used to get 18000+ on my 4.2 n4 and over 24000 with faux overclocking kernels for 4.2
Now i am getting 14000 - 16000.. With 4.3..
Sent from my Nexus 4 using xda app-developers app
it's 4.3 and new update of antutu....
you can use custom rom/kernel or some tweaks so you'll get over 23k
Just you...

different kernel works and reacts differently on different devices and different roms. test it out to find YOUR perfect fit.

Try the S4 dalvik patch that's floating around here. Boosted my score to 20k+ on PA 3.99 with stock PA kernel at 1512/1512.
Using this combo as my daily driver since a week and no problems so far.

What kind of numbers did you get before the mod?
Sent from my Nexus 4 using xda app-developers app
Around 16-17k if I remember correctly. Also don't forget that heat throttling is pretty aggressive on the N4. So make sure your device has cooled down before the next run.
Pro tip: put your N4 onto a cold ceran stove when benchmarking. They're made to conduct heat efficiently and will keep your device cool
Well I wouldn't give those numbers too much credit...
they represent more the settings that you enter, than device performance.
I for instance use the latest franco Kernel. With the settings I use every day (interactive governor, default clocks), I get arount 15-18k in antutu. But the device feels as snappy as hell in normal usage and gaming.
If I switch to performance governor, ramping the minimal and maximal cpu clock up to 1512MHZ while raising the cpu throttling from 65 to 90° I reach antutu scores in the range of 20-22k.
But I obviously would never ever use these settings every day.
That beeing said, these numbers do not really represent how the devices behaves in every day usage, which is much more important to me than any number, a benchmark puts out.

I have a couple of questions:
It's your phone still working like it should?
Do you really care about the scores you get to be able to enjoy your N4?
Do you think the scores of benchmark really say everything about your phone?
If you compare a S4 or M7 with a N4, and in one test (by chance) you get the same scores, do you think your N4 has the same power as a S4 or M7?
Stop worrying about benchmark scores, I used to be like that bench-marking all the time, at the end I just got tired of it!!!
Now I just enjoy my phone the way it is.
Good luck!!!

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.
