Since this is a popular topic and since MSNBERG requested that i make this, i have decided to make it.
THE GUIDE TO UNDERVOLTING
What you will need:
PREFERABLY the application Tegrak OVERCLOCK PAID! can also use set cpu
TEGRAK
LOAD THE OVERCLOCK MODULE
go into the "TWEAKS" section and be sure to select DEADLINE as your scheduler!!!
you will see the option "OPTIMIZATION" go there
now you will see 5 levels to customize
ONLY LEVEL 0 CAN YOU CUSTOMIZE EVERYTHING
Now if you only want to undervolt with no overclock here is the chart you need to use ON GINGERBREAD:
UNDERVOLT SETTINGS
level0 - 1000 - 1155 - 1065 -------this level can change frequency but volts need to change as well
level1 - 800 - 1040 - 1035
level2 - 400 - 955 - 960
level3 - 200 - 835 - 950
level4 - 100 - 825 - 930
once you enter these in you can go to tegraks main menu and go into "PROFILE" and you can save your current settings or choose previous ones.
Here are some overclock values you can use for level 0
LEVEL 0 1100 1100 1090
LEVEL 0 1200 1195 1095
LEVEL 0 1300 1295 1115
LEVEL 0 1400 1315 1125
LEVEL 0 1500 1375-85 1150
LEVEL 0 1600 1400 1175-1200
***THIS WILL BE UPDATED WITH MORE INFO SOON
In my best Mr. Burns voice: Excellent!
Always wanted a undervolting guide. Nice!
:C my phone reboots with these undervolt values for some reason. I'm running Valhalla 1.1(haven't has the time to update and don't have wifi so...) and adrenaline shot X. I also have stability checker off so I'm sure that's not the issue. Its fine at first but then rebootes once I start mulititasking like listening to music, texting and getting on Facebook at the same time. Seems to work fine for everyone else so I don't get what's going on

What governor and scheduler.are.you using

I'm using ondemand as the governor. I have no idea what a scheduler is.
*edit*
The io scheduler? Well its set to cfq.

Hi guys,
Sorry for the rookey questions, but :
1. Do I need to install TegraK kernel ? If so, before or after installing TegraK overclock ?
2. Will TegraK OC free version do, or i need the paid version ? what's the difference ?
3. ICY56 - I'm having the exact configuration you have (Valhalla 1.1 and Adrenaline ShotX) can you please explain what changes you noticed regarding battery consumption, and doesn't it affect your phone responsiveness, stability and performance ?
Thanks,
Itzik.
Answers
1) Tegrak will work fine with valhalla, most (if not every) custom rom has the needed kernel already.
2) You need the paid version because free version only allows overclock up to 1.3 you cant adjust anything else.
3) I can't answer as I'm not set up the same, but from my understanding you shouldn't see any negative affects, just increased battery life.
Every time I try to undervolt my phone. It reboots constantly. Even with ICBINB KJ1. Scheduler is set to deadline and governor is set to ondemand. What am I doing wrong?

Well I haven't noticed a decrease in performance and stability. The phone actually feels the exact same. As for bettery life, I can't really comment on that yet since I'm in the process of recalibrating my battery and I haven't been on UV long enough to say but so far battery life seems to be a little better

Even if I increase voltage it still freezes and then restarts phone @ 1600mhz
Sent from my SGH-T959V using XDA App
I've had 1664 mhz before stable. It can ne done, every phone will be different with what voltages work. experiment a little. But I wouldn't go to high, don't want a $500 paperweight.
@ 1.3 GHz, this phone its rock solid, so anything higher is over kill imo.

Has anybody tried using an app like no frills CPU gov. To change these settings and if so with what result? Anything better?
Sent from my MB865 using XDA App
I have used an app called system tuner I changed my cpu governor settings from moto hot plug to performance so far its much faster but it takes a little bit of battery and screen off governor changes to default no changes
Sent from my speedy Motorola atrix 2
I look at the other app they basically do the same lol
Sent from my speedy Motorola atrix 2
I personally like setCPU it is worth the price for the paid version. Try the free version out, it just wont let you reload the setting on boot. It will not take battery either. I used it on an inspire and a galaxy s and now this phone with great success.

I was wondering what mot hotplug governor was so I looked it up. Here it is
mot-hotplug is a CPUFREQ governor that optimizes SMP doing a fast poweron/off of the second core. It will make your device to act more smoothly and faster in some conditions.
Pretty cool stuff

I run on demand and notice no difference other than a bit more smoothness.

I'd like to know if anyone has made a kernel that supports overclocking past 1.68 Ghz, and what app they use for controlling the core voltages.. I've used SetCpu, Antutu, and Voltage Control, but neither of them seem to do anything regarding controlling core voltage.. Help me out people, and I'll try to return the favor!

Does he have kernels for 1.68+ ghz? All I've seen is 1.68 max.

And does anyone know how to adjust voltages from terminal emulator?
Sent from my Transformer TF101 using xda premium
There are no kernels over 1.68 Ghz becuase they would be unstable. In my case, I cannot go over 1.6 Ghz without my tablet hard resetting. So the answer to that question is no.

I love Setcpu because you can easily control the voltages, your kernel must support it thought. For example, I am running Clemsyn's and his DOES allow voltage modifications.
I pushed the wrong button and quoted myself XD. Disregard last post.

I'm running the blades kernel right now. And I think if someone created a test kernel, my Transformer could run about 1800mhz.. I run 1680 all day long, stress tests only get to 56 degrees celsius, and I have an extra 50 or 100 mV left until I hit the 1500mV cap.

To those rooted users, are you overclocking, undervolting? What app / method are you using? How is it working for you in terms of stability and battery life?
I just installed EZOverClock, set at Power Save - 1ghz. This is an overclock app for the Prime that works on our device as well. If you are interested in checking this out, the apk can be found here:

I am hoping for some solid battery savings without compromising performance on games such as MC3.
I find it hard to believe that I am the only one overclocking this device?

I'm underclocking using system tuner pro, setting max cpu at 880mhz when not playing games. As for undervolting afaik is not possible yet, at least in the stock rom.

Im overclocking it to 1.4 Ghz 100% of the time using antutu cpu master.
I havnt experienced any significant battery droppage and it seems to help load some of my large games faster. overall I like having it OC'd.

I have run the games at 880mhz and they run pretty much the same, but when my pad is not connected to a power outlet I set it at 1.1ghz to run all the high end games (THD, etc.). If I have it connected I just max it at 1.5ghz
I don't use ezoverclock since it won't let me go lower than 1ghz and as far as I remember ezoverclock didn't have governors, STP lets me change governors (I'm always set at interactive).

Yes, you need root.
I only use OC for Testing, Benchmarks and 3D Games.
But must say when I run it on 1500Mhz and Performance for more than 45 Minutes the Pad gets really warm.
Im at 1.2ghz right now, might underclock some more.

I did some testing and the kernel does not overclock to 1.5ghz its a miss read on the chip. 1.2ghz and 1.5ghz score the same on quadrant and antutu benchmark do this urself and see.

I can confirm this, with the stock kernel even though I can set the CPU to 1.5 even when I set it to the "performance" setting (the CPU options one, not the Asus setting) I've never seen it go past 1.1 Ghz. I think if we want higher OC's we'll have to wait for custom kernel's. We'll probably lose the 3 performance modes that are built-in from ASUS but honestly, anyone who's rooting and OC'ing shouldn't be using options that basic anyways.

Yes but the options are just underclocking
Powersave- 1ghz
Balanced-1.1ghz
Performance-1.2ghz
The battery consumption difference between powersave and performance is minimal been testing this myself.. but to be honest after buildprop tweak an overclockis not needed everything runs at optimal performance. Only thing i see overclocking for right now is show off high numbers.

would like to ask how is experience on an oc kernel @1.7ghz? getting reboots? crashes?
with my phone: some people have stronger cpu's and can get from 600mhz to 906mhz i can only get to 878 is this the same for the 300T? because mine has no reboots at all, no crashes/freezes nothing! and it is running constantly @1.7ghz
EDIT: is there an oc kernel available that goes to 1.8ghz? because i want to give it a try!

1.7 should be stable, I just posted a link to a 1.8ghz kernel if you check my post history, the amount you can over clock any CPU is different as every CPU is slightly unique, for us if you have a higher revision of the tegra 3 it should over clock to tf700 levels we just don't have any kernels pushing it that far
