Overclock Kernel Question

So I found a kernel on the Fascinate forums that was built off of our EC10 froyo source that was from nemesis2all and I saw that he had added the ability to overclock and undervolt from within the ROM so I installed it just trying (backed up of course) and found that it does indeed work.
I then got the Voltage control app from the market and started playing around doing Quadrant scores throughout after each change. I found that at 1200 mhz I was getting 1600s instead of 1400s and the phone ran great. But when I tried 1400 mhz the phone froze up and restarted while doing the CPU section of the Quadrant test so I reverted back.
My question is, what would be safe to stay at for general use?
Second question, how do you use the voltage app to undervolt I see the settings but I don't know what to set them too.
Here is the link to the kernel

1200 has proven to be the most stable overclock, any higher and it will freeze up eventually.
With voltage control, the way it works is that you set the max clock and then it will give you increments that the phone will automatically clock to within the guidelines you give it. Then for each increment you can set the voltage it will use. Just look around and experiment with voltages, see how low you can go without having issues and never set it to apply at boot unless you know that's what you want, other than that go crazy and a reboot will fix it if you have a problem.
I recommend keeping setCPU installed along with it, that way you can still force it to underclock or overclock or whatever. It all depends on how much you use the phone and what for.

I've been running overclocked at 1.3 and undervolted at least 50 for a couple days now. Only one issue and I'm not even sure it was related as it janet happened again. I posted my settings in the otb thread if you're curious.

H'm, I tried going up to 1.3 and it would freeze up after 5 or 10 minutes every time.
Like I said, 1.2 is the only one that has proven to be safe for everybody... not each phone is exactly the same and if akellars CPU has a soldering that is done a little bit different than mine, it might allow him to clock a little higher. who knows

I've been running it for a week @ 1400 -25 undervolted and haven't had any issues. The new 1.6 gives me trouble. I don't think there's enough overvolting in that one to make it stable for pretty much anyone. I use the 1400, 800, 400, 200 steps all undervolted @50 except 1400 which as mentioned is -25. Battery life is good because during sleep it doesnt really hit the high end and by not having the other steps its snappy when in use. Fastest this phone has been by far. I don't use setcpu because I think it and the voltage app conflict. That was nemisis's instruction to install it.

Yup I'm just lucky 1.4 worked for me too but I didn't see much of a performance difference so I didn't see the need to stress the cpu out anymore than I already was. battery life had been awesome for me with my setup as well.

[Q] Questions About [TouchWiz][6.05.11] OTB-Reloaded Kernel

I have a question about this kernel, i have it installed on the phone and flashed on it, it said in the post from nemesis2all that there was a Battery hack, i was curious how to use it, i currently have settings at Min=400 max=1300 all settings undervolted 50mV, how good are these settings? and would this be the optimal settings for performance and battery life? or anyone have a better setup that would help. seem to be getting high 1700 quadrant scores with how it is now.

In order to get the best battery life you would not want your phone over clocked, I run otb kernel as well and just uv the stock setting starting at 50 for the 1000, and progressively stepping down to negative 100. Anyways I run, 1000 -50, 800 and 600 -75, 400 200 & 100 at -100 and I have great battery life even with heavy usage and playing memory intensive games, paradise island, drag racing, pocket soccer. Unless your phone is laggy after you enable lagfix I think overclocking is probably just killing your battery faster the only roms I used light oc' ing for was phoenix and miuiwiz, where both launchers seemed to get some lag after a long days use
Sent from my SCH-I500 using XDA App

The other school of thought on battery life is, if you overclock the processor, it will finish the task faster and return to a lower power idle state sooner.

well also i used SuperOneClick to root the phone, is rageagainstthecage a good root to use? or are there better ones out there? also sometimes this kernel like to freeze at start up and i have to re flash it. im pretty sure this isnt supposed to happen. any help or advise is greatly appreciated

I've had issues with OTB kernals before. Your problem could be the kernel, but I see you oc'd it to 1300. That too could be causing it. Each phone reacts differently to kernels and oc/uv.

Are we able to still use any touchwiz kernal from ec10 on the new heintz 57 ee19 updated rom?

Well I re-flashed it and used same ovetclock just lower volts and am pulling a average 2100 quadrant score. Don't know if it means much but no lock ups anymore
Sent from my SCH-I500 using XDA Premium App

This could just be my stupidity, but if you can flash kernels then you have a custom recovery, right? What's the point of using super one click? Wouldn't having the recovery and the ability to change kernels, etc mean your already rooted? Just seems redundant, I never used a rooting app and still use all the root only apps....

Kinda. The only way to flash a kernel is with a custom recovery but you don't necessarily have to be rooted to do that. EE19 is not rooted so that's why you need SOC if you want to root. Rooting opens up a lot of options for apps and moving and copying system files but isn't required for Roms/Kernels.

Anyone have any other general good ideas or cool tricks to do to this phone?

Currently, im doing a bit of testing with the new phoenix 1.1 rom.
This baby can handle some crazy undervolting.
Currently:
1000 : -100
800 : - 100
600: -100
400: -100
200: -150
Going to see what i can get this down to...a bit more tweaking i bet the battery life can get phenomenal.

Try opening and closing the camera a few times in a row and see if it freezes. Or try a quad test, those are usually the things that will cause issues with too much under volting.

400: -150
200: -175

Usually ill run 4 quadrant tests and if it passes that it should be stable. Currently ran a 2187 is that a good score for 1.4ghz?

also when using the OTB kernal what are safe settings to use? ive been running it at 1400Mhz but it lockes up and geeps giving me force close things on start up and never stops and i have to reflash to stock and start over? im assuming this isnt typical, can any one help out?

Actually that's probably pretty typical for an OC that high. I know I can't run it that high without lockups. From what I see in the original thread, most people don't run above 1300 most of the time.

SetCPU supports Tegra 2 (V2.2.0)

SetCPU master coolbho3000 has updated his app to include support for the Tegra 2. It's available at all the familiar places.
2.2.0 - Added an "In Call" profile. Improved the Set on Boot safemode function by including a flashable zip that toggles SetCPU's safemode. Press menu on the main tab for more details. Added autodetect support for all Tegra 2 fakeShmoo kernels (ie. G2x). Added a "Voltage" tab for undervolting the CPU on fakeShmoo kernels, some custom Galaxy S kernels, and some Nexus S kernels. This is a full-fledged interface for undervolting these devices, and includes backing up and restoring and a Set on Boot checkbox. Improved the way SetCPU initially requests root. Various miscellaneous bugfixes.

Undervolting in SetCPU, now that's fantastic. By far the best purchase I've made on the market.

Also has a cool feature that allows you to extract a zip file to your sdcard in case you've set it to 1.5/1.5 and your phone freaks out. You can just boot into recovery, flash the zip and it resets setcpu.

I must say, SetCPU 2.20 is quite amazing... worth every penny

Note to ppl who upgraded from existing setcpu...re-detect your cpu speeds from the main screen. Otherwise, voltage tab will force close on you.

What would you set "in-call" to?

I have 400/400 for screen off. I set in call to slightly higher at 400/500.
I'll need to test it tomorrow during calls and see if the screen wakes up quicker after a call ends.

For benching, I set it at 1500/1500 at 1300mV with no profile set for maximum power, and I'm getting much lower benchmarks in Smartbench 2011, than I was with pimpmycpu. Why do you think that would be?

I did the same, but unfroze SETCPU and FROZE pimpmycpu.
In the transition, the battery got drained quite a bit over a few minutes, and heated up pretty fast when initially recharging. I had rebooted in between, but there may still have been some residual conflicts between the apps.
It froze at one point, but after a battery pull, it settled down. Overnight battery drain (with screen-off profile set pretty low) was only 4% over 8 hours. This is on EB 1.0.2 and faux stock kernel. Quadrent "only" around 4000, but everything works and this has apparently improved battery life.
A note on pimpmycpu - I thought scaling to min had stuck, but apparently not. Battery consumption was 12-15 % overnight compared to the above.

Thanks OP! I severely dislike pimpmycpu...

I have not seen that, although compared to Quadrent, I had not seen the very high scores that some had. I doubt SETCPU would impact you OC'd performance at max setting (although pimp had scheduler settings and SETCPU does not).

Over 1.2GHz = Lock

Hello everyone. I have had my Nexus S 4G for about 2 weeks now, and I have tried everything I can think of. However, I cannot overclock my phone higher than 1.2GHz. If I set it to 1.44GHz (or even 1.3GHz in most kernels), within the first five minutes, it locks up, requiring a battery pull. I have tried just about every kernel. Trinity, Netarchy, Matr1x, everything. However, I get the same result. I am assuming that it is just my phone. I know that when I had my Evo, it didn't want to OC past 1.1 GHz stably, but the refurb I got from Sprint ran at 1.21 GHz like a champ. I was just wondering if anyone had the same issue, and if so, if it was possible to alleviate this problem. I would love to run my Nexus at 1.44 GHz, because some of the Quadrant scores look amazing.
Thanks again for reading,
StompySan

After running Quadrant twice with it set at 1.3, I got a lockup. 100% not responsive. Had to pull battery.
EDIT: I tried benchmarking my phone with CF-Bench, thinking maybe it could have been a fluke with Quadrant, and had the exact same results. At 1.3 and 1.46GHz.

Ok if neither of those work I need you to do 2 things.

I can overclock without reboots to 1.2. Any higher than that is when the problem arises.

Ok now once you flash v9.0, go into setcpu and raise all voltages by 30

OK, so Quadrant ran fine for 5 tests, and CF-Bench ran OK as well. Should I push it up to 1.46 now?

Try it, and if you get a reboot, raise voltage for 1.46 by 10.
Sent from my Nexus S using XDA App

No lockups yet! I have ran Quadrant 5 times, CF-Bench 2 times, and Linpack a couple times. Seems to be doing great! I am going to test it more thoroughly tomorrow (it's almost 1AM where I live, lol), but it seems great right now!
I have never increased the voltages on a phone CPU before. I have done it on my brother's computer when I overclocked his processor, but I generally try to avoid it. I am just really paranoid to mess with the amount of power going through the processor. That's why I turned to the professionals in this case. Thanks again for your extremely quick reply.

Cool! you just needed a bit of a voltage push, that's all
let's hope 1.46 ghz runs well

Mathkid Ive never been stable past 1.3 so I followed what you told him to do and what do you know! Perfectly stable so far at 1.44 on apocalypse kernel!! Might have to try your 9.0 at 1.46 soon!
Sent from my Nexus S 4G using XDA App

So is there a limit to how far one should overvolt? I upped the voltage at 1440 mhz to 1550 mV. Did run rather stable except for "Lets golf HD!" which froze. I would really like to be able to run at 1440, but not sure what to do. Im using Apocalypse Talon 3.2.1.
Do you think your kernel would handle OCing better, mathkid?

Yeah you can try it out and if you need to raise voltages go ahead

Best overclock value

Hello,everyone....recently I overclock my desire s and thanks to many of you I received many useful information so I want to share impression how overclocking has improved performance and battery to help other like us to know what and how to use overclocking and governor....
So I start ....
I use Viper saga with tweaked kernel 3.x/ondemand with deadline/cpu min.245-max.1410
I noticed that my graphic is very good and everything works like a charm....for example in FIFA12 I noticed that even the shadow of all player are so intense and everything is so clear,it seems that improves my graphic and my phone is faster..I hope that overclocking to 1410 to not damaged my phone.So what configuration do you have ?
Sent from my HTC Desire S using xda premium

Set the governor to performance. Battery eater though. But u only can choose better battery life or smoother graphics, so make up ur mind and choose one :thumbup:
When playing with overclocking unstick 'set on boot'. So that it goes back to normal once reboot in case of any freeze. Overclock it based on ur desired value, experiment with it, slowly. increase the value step by step. Leave it for a day then increase again. If it freezes then u know ur phone's limit.

i have read that people say it's stable up to 1.5 GHz.
I have set mine to 1.3GHz to be on the safe side.
And set it to,on demand,so it only takes up more when it needs to.
setting it up to high speeds can result in a melt down,draining batteries and will shorten out the life of your phone even when stable for a couple of days so be aware of what your doing...

there is no best value for everyone, some say 1ghz is enough, some say 1.5 ghz is not enough.
so it depends on what you need, its a trial and error thing
u will get a fast response phone but battery life is sucs ... cant complain though

If you want separate screen on/screen off profiles, I would recommend daemon controller app (with andrev_oc installed through the app).
If you want more profiles for different situations, setcpu is probably the only real option.
Setting to 1.3 GHz depends on the kernel you're using, not on the app.
