Overclock Nexus CPU? - Samsung Galaxy Nexus

Will it be possible?
From anyone in the know, are we far off from a CPU OC kernel?

why?! The battery life is mediocre as it is!
Undervolt/underclock could be useful tho.

the screen and the radios are what drain the battery the most.
overclocking won't make a big dent on battery life. but better clock speed management may actually improve battery life.
To answer the OP's question, It's inevitable. the chip is a TI-OMAP, and the original Droid came clocked at 550mhz but was a 600mhz chip. It was able to Overclock to 1.1-1.3GHz stable depending on the persons phone.
I'm not saying we'll see a 100% increase on the Nexus, but It's hard to imagine not getting past 1.6 GHz considering the chip is actually 1.5GHz.

[Q] Any1 underclock + undervolt?

If so, does it help your battery life? and share your settings please
underclocking to 800mhz has no impact on performance AT ALL unless your playing games even still, not much of a difference.
has a pretty good battery advantage with that being said. I keep mine underclocked to 800mhz and have no issues lasting pretty much the whole day with moderate to heavy use

Overclocking adn Undervolting

I need a link to a tutorial for the epic 4G please.
Can anyone explain in a couple of sentences why undervolting is good? Does it save battery life? If so, how much?
Also, how much of an improvement are you getting in tasks like playing and recording video from overclocking? What functions of the phone benefit the most and are there any battery-life effects from it?
Thanks

Improvements are small, but everything counts - bad analogy > 10volts uses more electricity than 9volts - if you could make your CPU run at 1ghz with 9volts instead of 10volts, you would be saving electricity, ie battery.
With that being said, lets say CPU's from the factory can run at 1ghz at 10volts plus or minus 1volt, but they set it at 10 volts because they know it will run safely, even though it could run at 1ghz with 9volts. But not all CPU's are created equal - so similar 1ghz CPU from the factory will have some variance. Some 1ghz CPU's instead of saying they run at 10volts plus or minus 1volt, they may have a specification of running a 1ghz CPU at 10volts plus or minus 1/2 a volt - that's why when some people try and undervolt to much, their phone might lock up - and then there are 1ghz CPU's that can't undervolt at all and must always have 10volts to even run.
Over simplified, but you should get the idea.

[Q] overclock

i have setcpu and the lost rogue v1.3 and i what to put it at 1704 MHz but it freezes or reboots, so what could i do? what voltage?
You can try upping the voltage, not every phone will run at the highest speeds. Overclocking is luck of the draw, not every processor will react the same. My phone requires 1550mv @1.6 to be stable and 1.7 is not stable. There is no real advantage to running the processor this high anyways. 1.2-1.4 is the sweetspot, 1.2 does everything the phone needs to and you usually have room to underclock, to increase battery life and usability of the phone. Benchmarks can be fun but imo, stable phone @ lower voltage > semi-stable benchmark monster @ high voltage.

Agreed, I have tried all sorts of overclocking and always go back to 1.352 or 1.2 because of stability. Sure you can bump it up and get high benchmarks, but who cares it is just a number. I would much rather have lower numbers and a stable phone.
I am running New Senzation ROM with the Desparado Kernel and I am running smooth and blazing fast at 1600. I actually can run at 1704 but dont like to overclock to that speed for very long but havent had any crashes.

Wanna trade phones? I wonder if you could push it higher? I can get mine to run at 1.7, but it will eventually crash within a few minutes. 1.4 seemed to be the most stable (and got the best quadrants) , but I don't bother OC'ing anymore. The phone runs fine without it. I don't really ee the point. I do notice some lag hear and there at 1.6.
I almost always am in the 800mhz range and rarely does my phone jump to 1ghz and definately almost never hits 1.2ghz. Besides trying to get your phone to give you some meaningless number as far as the real world is concerned ( quads) there is zero reason to ever overclock THIS phone. This phone has better battery life than iPhone with a slightly higher clock which is awesome. It actually performs the best of any phone to date. People conatantly hate on apple so hard to the point that when apple actually does something thats honestly great people still see the cup half empty with them. Apple has some of the best battery life of any smart phone to date. It also is one of the smoothest UI's out. They are a smart company and have great hardware. The example i like and cheer them on for is there way of using there cpu in a certain way. They have a really beefy cpu and then they underclock it quite a bit so it just sips battery power. Yes apple doesnt actually multi task so its easier for them to achieve battery life this way easier and it requires more cpu to run our phones as they have REAL multi tasking but i use the same idea. I underclock my phone to run at 800mhz till i reach 80% cpu load then bump to 1ghz. I never have my phone shutter or lag. The GPU is a monster. I get sooo much more battery life out of it. Overclocking is nearly pointless as a daily driver on this phone. In the past with my HTC Eris and HTC Evo 4g i had to overclock as muCh as possibly due to lack of a powerfull CPU and GPU but this phone (just like iPhone) has more than enough muscle and should be under clock 200mhz with no ill effect at all. Thia phone truely is the first legit android device in my eyes because it has more than enough under the hood. Underclock 200mhz and undervolt -75 and this phone truely shines and comes out #1 phone today in ALL areas. Smoothest scroling, lagless and best battery life to date. I love this phone and my set up

Undervolting

I thought an Undervolting thread would be good for me and I'm sure it will help others. Messed with it a little bit on my Inc but haven't on this phone yet.
How much do you undervolt by?
How much better is the battery life?
Any kernels that work better with undervolting in your opinion?

Well, it's not really needed.
I think most kernels already undervolt themselves to the possible max.
I know Franco has something called Smartflex, which takes in a bunch of calculations and undervolts it at the most optimal level (I think) and undervolting manually doesn't give any more real world battery savings compared to it.
But either way, I'd recommend Franco kernel for some of the best battery life.
Straight 175 seems to be safe for most people. I can undervolt lower. I can UV much lower but then I get a reboot at least once a week. The nexus is so efficient at many things uv'ing helps but doesn't impact usage that much. Honestly I don't think you get but about 30 minutes tops extra screen time and I'm being very generous. Uv'does help keep temps down and helps longevity of phone life.

Undervolting shouldn't be relied on for better battery life. It is such a minuscule amount of electricity change. The only thing undervolting should be used for is stability in OC.

[Q] Best frequency for overclocking with battery life in mind?

For the people that have been overclocking this phone for a while now, what are your opinions on the best max frequency above 1.5GHz to clock to while still keeping decent battery life?
Overclocking isn't exactly a battery friendly thing to do, you will see battery drain if you clock to higher frequencies. My only advice is don't oc too high if you want to keep battery life in mind. Going to 1.67 or 1.72 should give you a decent speedup without murdering the battery.
I run mine at 162 its no diff in voltage from 151 at least on uber kernel it is.. Also try to under clock the the freq until or happy and no random reboots
