Custom Kernels for the eris? - Droid Eris Q&A, Help & Troubleshooting

I know for the droid there are lots of custom kernels that use very low voltages for high speeds. Do we have custom kernels like this?

The processor in our phone is that of the original 2g/3g iPhone, the 528mhz Qualcomm (that should have been updated 3 years ago).
The processor in the Droid is the same as the iPhone 3gs (except 550mhz clocked instead of 600mhz).
The Droid processor has a floating point co-processor (sort of) which is why the Linpack scores are WAY higher than ours (it doesn't actually mean the phone is faster, it just does certain floating point operations faster).
The Droid processor is also SEVERELY underclocked, probably for power reasons. There is more of a demand in the Droid crowd to control power usage while still increasing speed (hence the low-voltage kernels, etc). "Lower voltages" are found by using different ways to multiply the frequency, but in a processor like ours, we are limited in the different speeds we can multiply (not to mention a ceiling of reasonable operation being usually 800mhz or below).
See, some people want their droids to be at 800mhz. They want that great battery life, to keep things cool, and a small performance boost.
Some want to go up to 1300mhz, maybe because they play games, or because the think they're cool, or whatever. That requires different methods for overclocking (depending on which exact speeds) and uses a lot more juice. You could use a 1300mhz kernel and keep it down around 800mhz (or whatever specific speeds the kernel allows), but that kernel might not be built for low voltage - you might just be still multiplying a number that keeps your voltage high, instead of the 800mhz Kernel that only goes so high, but keeps things easier on the battery.
Our Eris processors are more limited. Pretty much, you want your Eris OC'd (usually to the 700+mhz somewhere is all you get), or you don't. If you don't want it OC'd, you just don't install SetCPU. If you do, you install and use it (or whatever other overclocking app/widget you want).
To use your Eris low voltage, you pretty much need to stay 480mhz or lower. I keep my sleep SetCPU Profile at 122mhz-480mhz. VERY good on battery, and it throttles up to 480mhz (so the phone rings faster) when it's time for a call to come in.
Some Kernels have some things enabled (netfilter for wifi tethering and other things, a2sd enabled, overclocking, etc - depending on how it's put together). It's probably best to have a kernel that allows everything, since with our processors, there's not much of a power drain penalty (none that I know of in fact) for having a different kernel, and just running at 528mhz. I notice no battery difference at 806mhz in fact, it's a matter of having SetCPU profiles (or whatever) set up correctly and effectively.
Here are a few Kernels you might find (but most are incorporated in ROMs already, so you'll virtually NEVER have to flash it - except that I use Ivan's Eris_Official 1.0 ROM with zanfur's beautiful v3 kernel - it works perfectly at 806mhz on my Eris).

The point is that for us, it's not that useful to flash kernels. Most of the ROMs you'll download (even the most 'basic' ones) have all the goodies enabled on the Kernel.
Different phone, different hardware, different ballgame.

God damn. Best answer I could have hoped for. Seriously thanks a ton man, that was everything I could have wanted to know thoroughly explained.

nvm. answered my own question hah

I'm on Conap's new CFS Kernel. I multitask a lot so that's the kernel for me. Everything feels more responsive. Like 1.5x the responsiveness from the (I think) BFS kernel nonsensikal comes with. I typed all of this without even a hint of lag.

BFS or CFS

Now that both kernels are out and a lot of people have had time to play with them, I was just curious as to anyones preferable tastes, stats, why's, issues, side by side comparisons, recommendations, settings, what rom your running, things of that nature.
Well apparently BFS was developed by an Australian anesthesiologist and everyone knows Australia sucks, so go with CFS.
Seriously though, I get consistently higher Quadrant scores, 5-10 points at the most, with BFS but the applications and webpages seem to load slower. I don't normally use Quadrant to call or text so I have CFS flashed. Thanks to Decadenc3 and Conap they're both pretty stable and easily interchangeable.
CFS is the standard honestly. CFS is best for multitasking and general use. If you're going to use something like an emulator or a lot of heavy games I suggest BFS, since it's best at single tasks and making the best of minimal hardware.
I agree with the above. I got a 480 with BFS on the Quadrant benchmark test, but CFS is better for me in terms of day to day and I still hit high 460s.

Ok, since it hasn't been stated:
in a nutshell..
BFS is designed to focus on the main app installed, and process everything around the open app.
CFS is built around multi-tasking power.
If you want high scores (aka focused power), use BFS.
If you want fluidity and ease of use throughout the full phone (multitasking) use CFS.
In general most people will prefer CFS because you notice less issues. If your a single app kind of person use BFS since your focused, but your scrolling, and swiping actions will be a little more laggy.
Izeltokatl,
That's basically what I was getting at in post #3, if you want to do a single task as fast as possible use BFS, otherwise stick to CFS for overall stability and multitasking.
Thanks guys, CFS it is!

Overclocking - Is it really worth it?

Hey all,
I come from an extensive background in OC'ing my own systems, pushing them to the extreme for noticeable performance increases. The one thing I know though, is that it does add wear and tear on the components, and shortens their lifespan. Is overclocking the Vibrant really worth it? I'm not sure if, with a ROM like Axura 2.2.5.7 which is blazing fast already, an extra 100 or 200 mHz is really worth the risk/performance.
What do you all say?

the only reason i OC is basically just so i can tell myself that i am OCing. If that makes ANY sense. its basically just my phone OCD.
to answer your question, even though you kind of already answered it yourself: the only reason you would actually NEED to OC is if you game a lot on your phone, if you do a lot of multitasking, or if you have a lot of data transfering going on (which i do). other than that, our processor is pretty powerful, and can handle 95% of what is thrown at it.
With that said, since youve indicated that you are satisifed with your phones performance, i would say the only thing you should definately do is install a lagfix (if you havnt already). if you dont need to OC, do your battery/hardware a favor, and dont.....unless you have phone OCD like myself.
PS - not to ramble on, but there was actually a 2-day period where i actually wasnt OCed and i didnt know it (i guess my app reset itself or something). i remember saying to myself during that time that my phone phone seemed a little laggy and much slower than usual....then once i discovered that my OC wasnt applied, it made sense. but keep in mind, i have my phone doing a lotttttt of things constantly, so OCing may not have the effect on lighter users that it does on myself. pretty crazy what a .2 ghz difference makes
Like above stated, OC is only needed if you do some intensive task on your phone. In addition, most of the Overclocking Kernels are targeted at a broad audience, what I meant by that is the developer bumps up the voltage enough so that only a small amount of people experience crashes. However, user generally have no control over the voltage themselves and any increase in voltage is bad for electronic components. (exception being some of Eugene's kernels which allows UV by user).
I don't, its not needed. I like my battery life.

I dont usually oc unless I am near a power source. last night i tried the Dow kernals and wow my phone was dead within ours even while in standby. Imo thats just nuts. Even while Oc'd it shouldnt die that way.
What I am looking for is a kernal thats compatible with nero v3 that will maintain battery life aslong as I dont oc.
I have seen this post http://eb-productions.proboards.com/index.cgi?board=samsungsgs&action=display&thread=28&page=1 on Eugenes forum but non of the info makes sense. The one that does make sense has a older modem than the one I am using.
I guess I am use to the hd2 in which I would underclock to maintain decent battery life and use profiles. It doesnt seem like this cpu likes the profiles. amirite?
I would OC no question if we could get a UV kernel with good battery life like we did with Eclair. I won't do it with Froyo because of the terrible battery on i9000 kernels.
Sent from my SGH-T959 using XDA App
What TopShelf10 said is correct. Basically the trade off is this.... faster kernel.......quicker battery drain. That is the trade off. I have used oc kernels ...I do not use the phone for games, so EVERY thing I do on the phone the oc is not necessary. That statement is true for 95% of us.
BUT, that said, there is some cool macho feeling you get when your phone is in overdrive, just like my car, 350 hp but I live on an island that only allows 25mph speed limit...still, it doesn't change that feeling of awesomeness I get when I start the engine
I had nothing but issues with each and every OC ROM I tried. App alarm, pandora, slacker, ect. It was always something. My phone would actually get random freezes so it made the phone feel slower. Voodoo or OCLF on the other hand work wonders.
is it worth it?
well, here were the trades i had with dow14:
going from 13-14mflops to 18-19mflops in linpack (yeah, it's a benchmark, but it's hard to otherwise convey how the oc directly translated to the phone being extremely fast otherwise).
battery life went from easily going 22+ hours between charges to going 6-8 hours between charges.
however, with the core 1.2 oc i had great battery life and performance. so i assume (and have gathered from reading people more knowledgeable than me) the battery downside is due to it being a i9000 kernel. so hopefully/eventually we will get source for the vibrant 2.2 kernel and get an oc kernel with similar performance but much better battery life.
and until i flashed nero v3 and using voodoo, i kept super io and dow14 kernels on my phone so i could flash the oc if i wanted the performance or flash super io for battery life/day to day.

[Q] Over Clocking Kernels

Samsung Fascinate CDMA
Rooted MIUI 1.9.16
Did a brief search here looking to understand how to operate overclocking kernals, but find it/me relatively limited.
I have installed and ran Glitch v11 and v12, played around with HL to LL, and made adjustments to undervoltage utilizing Pimp My CPU and Voltage Control. I have also ran Tweak (though not really a kernal).
My question is this,
am I overclocking when I reduce voltage on Mhz's above 1,000?
If not, could someone point me to, or explain how to achieve overclocking on our phones, and
which kernel and governor do you prefer for overclocking?
As an ammended note, I've installed Tegrak Overclock, but am still looking for a user guide...
Thank you for your time.
If you're the running the glitch kernel...use voltage control, not tegrak overclock...over clocking is when you turn the CPU speed above its normal speed..anything over 1GHz.
under volting is when you turn down the voltage frequency to achieve better battery life...
Any one clock speed may perform more or less stable with different under volting unfortunately all of our phones will vary in performance so one setting that works for one may not be the best for another so experimentation is really the best option...this applies for schedulers and governors as well.
I personally overclock as high as I can until it freezes or crashes..then I go 1 setting down...I then try undervolting different steps observing the stability of my phone...when I find what I like,I run it for a few days, then if its still nice and stable I will apply on boot.
The different leakage values are affected by the hardware quality of the chips in our phones which also vary..I start with high and see how high I can overclock..note the setting, then try medium..see how high I can overclock and so on...just as a reference..high leakage creates the most heat and is the least efficient, but works for most phones, while low leakage is the most efficient and generates the least heat and will work with not as many phones

How do you over-clock using Glitch and Voltage Control? I see that Voltage Control goes up to 1,300Mhz, but it's at 0 above 1,000Mhz and can be dropped down to -200mV. Is overclocking just the process of decreasing that voltage on Mhz's above 1,000Mhz's

come on man.. Clock speed (mhz) and undervolting are 2 completely different things.. Forget the voltage.. No changing the voltage is NOT overclocking.. You overclock by changing your maximum clock above 1000mhz which is stock for this phone.. Try long pressing 1200mhz and selecting set as max.. Now your overclocked to 1200mhz..
Sent from the fascinate that holds the record benchmark on antutu
No decreasing the voltage is simply undervolting whether it's over 1000 or under. The idea behind undervolting is increasing battery life, but you can't necessarily go and set each level to the maximum undervolt (200) you half to see what works. Increasing the processor speed is overclocking, stock speed is 1000 so anything over that is over clocked. As far as how far as how far you can over clock depends mostly on 2 things, 1. the kernel your using, ( for example if it shows 1300 in the list that means thats all that specific kernel supports) 2. It varys greatly between phones. For example with glitch you can overclock to 1700 but very few phones can run that high for longer than a few minutes!
Hope that helps.
Sent from my SCH-I500 using xda premium
Yes.. And the fact you say your running glitch and your max oc is only 1300 my guess is you broke your kernel with tegrak overclocks module.. Delete tegrak and stop downloading overclock apps. or any other root app unless you know fully the consequences first.. If after deleting tegrak, and rebooting, if your voltage control don't show a maximum clock of 1700 mhz, then you will need to reflash your glitch kernel

Neh4pres,
Yeah, I kind of feel like a heel. For some reason, I had a brain fart when looking in the 'General' section of Voltage Control. I see now how to overclock.
Regarding ost #6:
When I flashed MIUI 1.9.16, I did not install any kernel; so it was kind of a half truth in that while running 1.9.9 I did have Glitch installd. Nevertheless, I still have Voltage Control installed.
mkropf,
I see that now, and thought as such earlier, but needed some clarification.
Having so many issues with Glitch and 1.9.9, I'm hesitant to install Glitch, but interested to see if it runs better on the newer MIUI...

A concern I have is that now my phone will not Auto Rotate to Landscape even though I have Auto-Rotate 'on' in Settings.
I've scoured Sixstrings Glitch thread to no avail. Though it's not needed anymore, I also flashed the cleaning script just to see if it would make a difference.
Is there a work around or fix for this?
Make sure you're on the latest 9/15 version of the kernel. Anything before that will kill all of your phone's sensors.

You wouldn't want to use my voltages, I put everything way lower than anybody else does or recommends and am just lucky that it is stable for me but it causes the sleep of death for anyone else.
For comparison, just run JT's kernel for a bit and then flash glitch and try it... once you play with OC/UV and voodoo color you won't be able to go back. (you'll be able to but you'd have to be insane.)

[Q] Unable to overclock and keep running

First I am aware that overclocking is not "safe" and all that kind of stuff
However for some reason I am unable to OC my SGS2 and run the phone on a steady way.
I have tried several ROMs (stock and custom) with different kernels and OCing apps with no avail.
I am not even able to run at 1.4Ghz or 1.6Ghz without having my phone reboot or hard lock on me.
Is there a particular or recommended setting (most successful combination) that anyone out there can suggest me trying?
Sometimes it will hang under heavy gaming but sometimes even browsing app and regular stuff will cause the phone to reboot or lock. If I work with no OCing at all then everything is fine and dandy.
Thanks, you can see my current configuration @ my signature.
Sounds like a very temperamental cpu. Currently I have the same setup you do and have never had issue with 1400mhz or 1600mhz. Though I usually leave mine at 1200mhz. What app are you running when it hangs?
And just as important, do you have alot running in the background? The modified touchwiz launcher unnamed comes with can be enabled to show a red dot next to the apps that have been opened and are in the background.

Not all CPUs can overclock - there's a reason it was sold as a 1.2 GHz chip.
Well as I've mentioned before, it could even hand when browsing through my apps menu, browsing the gallery, playing a game (non in particular) and the funny part is that the phone is not even hot to touch.
What I know for sure if that if no OC = no hangs, no reboots.
I do have the App monitor widget that comes with the stock ROM and currently using it on UnNamed 1.3.1 and I only have Widget Locker App. However I have try closing it and still will happen.
Not sure if maybe this CPU is somehow having an issue that makes it unstable as soon as I OC it.

Now that is new to me, I thought that all of them were OCable. Is there anyway to identify which can be or not OCed?
nope.. just by testing. it does have to do a little bit with the kernel and rom. the roms didnt originally have stable OC. i would assume that all of them do now. one thing you might try is giving them a little more voltage (just a little) at the higher clocks, but be careful. if you increase the voltage that means that you will sink more enery through the cpu and it will get hot quick. make sure you watch the temp.
i find that setcpu is less stable than the built in cm7 oc menu but cm7 doesnt have a voltage menu.
but on the same token... why OC? i can and i did but i dont need to... everything is like butter and i didnt see that huge a gain by OCing it anyways

have you ever overclocked PC CPUs? if you have spent much time doing that, then you would know that not every chip, even within the same model/family, will clock the same. take 2 CPUs, from the same batch, same model, with identical hardware tied to them. you will probably find that one clocks higher stable speeds than the other.
its very likely the proc in your phone just cannot handle the overclocks that the next person's could.
Like pirate said, no two pieces of hardware are identical. Sort of shows how much variance there can be in a manufacturing process. Id guess theres a few chips that come off the same line that arent stable at 1.2 ghz, but they dont make it to the devices, whereas one that can handle a higher clock will. (No sense tossing one that exceeds minimum requirements, thatd just be throwing good hardware away)
You could try nudgin the voltage up and seeing how it behaves, just use caution.

To get mine to overclock to 1.4 and 1.6Ghz I had to actually INCREASE the voltage settings via Voltage control app. So my settings are: 1.6Ghz= 1475mV and 1.4Ghz=1325mV
Try those out and see if is better for you. I tried undervolting the higher voltages and would either lockup or reboot instantly until I tried adding voltages. So you may need to play with your settings to get it to work for you.

Yup, or if they want to sell a "premium" device with a higher clock rate, they will take the parts that test well at 1.4 and sell them as such - meaning parts rated 1.2 will be LESS likely to be overclockable if a device comes out with CPUs rated at 1.4 - like the Galaxy Note did.
Before, anything that could meet the requirements of stable at 1.2 was sold to any Galaxy S II - but now, the premium parts are going into the Note.

To get mine to overclock to 1.4 and 1.6Ghz I had to actually INCREASE the voltage settings via Voltage control app. So my settings are: 1.6Ghz= 1475mV and 1.4Ghz=1325mV
Try those out and see if is better for you. I tried undervolting the higher voltages and would either lockup or reboot instantly until I tried adding voltages. So you may need to play with your settings to get it to work for you.

I am having the same issue as the original poster on my new GS2. I will have to try the settings you mention but would it be possible to do this and also apply /UV to the remaining lower (1000ghz to 200ghz) processor speeds and maintain stability?

[Q] what do you oc to?

Hello! i am in the process of overclocking my thunderbolt in order to get better performance with the eternity rom, and i was wondering what you guys oc your phones to? and if you do, what program/setting do you use to do so? (i plan to use a script in init after have found suitable settings)
I, personally, find it pointless to OC the Thunderbolt. The phone is fast and smooth enough for me on the stock speed, plus the battery life is bad enough without adding more strain to it.
However, if you insist on OC'ing, 1.2GHz is a safe bet. Some people can get to 1.4GHz, but then you run into freezing and random reboots. Also remember that individual phones handle overclocking differently. Where one phone can run perfect at 1.4GHz, another might freeze instantly when going that high.
Good OC'ing programs include SetCPU, No Frills CPU, and ROM Toolbox.
I don't overclock. That being said i have OC'd my phone b4 i have had it up to 1.8 Ghz stable, but it doesnt seem to make anything run faster. I use the Thundershed version of CM7 and its super fast. I dont think it could get much faster. and without overclocking i get better battery life.
thanks for the info actually ended up going with the lean kernel which is oc'd on the kernel level, works fairly well

Leankernel is tops. I use battsaver mode which is stock speed and undervolted. Smooth as butter on my phone.
