[1.267GHz!!!] [Devs] Overclocking/undervolting patches (update 6/15)

I got an EVO myself and managed to overclock it to 1.267GHz. We could probably go even higher, but that requires more extensive changes. Here are the changed source files: http://dl.dropbox.com/u/36553/supersonic_oc-uv.tar.gz
It also includes an undervolt courtesy of pershoot (a whole 0.1V lower when idle, which should help battery drain a lot!). Here is a test update.zip: http://dl.dropbox.com/u/36553/supersonic_oc-uv_signed.zip (working WiFi). Make sure to do a nandroid backup first!
Sensors/camera do not currently work in this kernel because the source is not yet complete.
There is an overvolt on the highest frequencies. It should not cause any issues. Thanks to toastcfh for his source, Herver for creating the first booting overclocked kernel on the EVO, all the kernel devs in the N1 community, especially pershoot and kmobs, richardtrip from the Desire community, koush for anykernel updater, and all who helped to root the EVO. Enjoy!
Update 6/15: Fixed 950mV undervolt. Raised voltages from 1228800 above to improve stability. Source files updated and update.zip uploaded.

I posted these in an earlier thread, but I think I should bring this to everyone's attention. Here are some simple patches that will overclock the Evo up to 1.267GHz (though by any means it's not guaranteed to get that high!):
Edit: please don't flash the below update.zip, as it doesn't seem to boot. Devs, the patches are still below, and a zimage is in the anykernel update zip.
Update: I compiled it myself. Here is an update.zip: http://dl.dropbox.com/u/36553/update-oc_signed.zip. This uses toastcfh's sources, Koush's excellent anykernel updater and a config.gz pulled from a stock Supersonic. If this doesn't boot, no damage will be done to your phone. Just reboot into recovery and reinstall your ROM. You can test overclocking by grabbing SetCPU from my sig or changing the cpufreq values if you know how. Once we get this working, I will create an undervolted version for battery savings. I'd get an Evo, but it's sold out everywhere T_T
http://dl.dropbox.com/u/36553/supersonic_oc.zip
cpufreq.c and acpuclock-scorpion.c are in arch/arm/mach-msm, and supersonic_defconfig is just the config. I don't have an Evo, so I can't test these out, but these should work with the source files toastcfh posted earlier: http://forum.xda-developers.com/showthread.php?t=686240.
Undervolting can be achieved simply by adjusting the voltages (in mV) in the acpu_freq_tbl table in acpuclock-scorpoion.c. For those not familiar with his work, you can see pershoot's safe (but lower) voltages for the N1 here: http://github.com/pershoot/nexus-kernel/blob/master/acpuclock-scorpion.c. If you want to overvolt or go under 1000mV, you have to make one further adjustment to the voltage regulator in board-supersonic.c.
Note that the N1 and the Evo are completely different devices (with similar processors), so what may work for the N1 may not work for the Evo.

I don't recommend overclocking, the devices already can run warm at current settings.
But then again, you are entitled to do as you wish.
Options better than overclocking are to remove the Sprint bloatware and strip down parts of Sense, this speeds things up alot by removing excess background applications.

Well it ain't too bad, my Droid at 1 ghz(550 stock) runs great.
So this should be good too.

I like overclocking as much as the next geek, but on the Evo... WHY?
This phone has yet to respond anything slower than instantly to my input and I expect a difference of .26 ghz would not make it so it could read my thoughts.
Undervolting, on the other hand, could help with the abysmal battery life...

Some people love to run benchmarks. Try to improve on them over and over. Others like the feeling of just going faster. Also some apps or some in the future might require a faster running phone. What better way to achieve that (other then buying a new phone) then OC.
Also in the future, are you not gunna buy a 1.5ghz processor phone running 2.1 because a 1ghz processor can already do it? OC has many benefits, just not to everyone, most because they dont understand the consequences or benefits.
My htc hero clocked to 768mhz can run 2.1 and everything near instant. Still doesnt keep be from wanting a 1ghz or higher.
Also one more thing, 2.2 will be out soon. With full flash support, i have a feeling its going to require a lot of CPU. An OC Evo would probably run many things from 2.2 a lot easier.

Well, I agree with the benchmarking comments but on the subject of Froyo... Froyo is designed to be even faster on equivalent hardware than 2.1... and 2.1 on my Evo is smooth as silk. And the Evo handles most Flash I can throw at it, so I'm not sure. I have however noticed a small performance difference with live wallpaper running, so maybe OCing will clear that up a bit.

You know, this is an excellent point and I feel like I failed the developer community in some small way when you had to bring it up. You shouldn't have to provide a reason for wanting progress, it should happen for its own sake.
Proceed.

I'm not trying to start an argument at all but you have to think broader mathematically. If the processor runs at 1000Mhz or 999mhz (In the case of my N1) a .267 increase is 267mhz, a 26.7% increase in computational performance... That's pretty raw especially in cellphone terms, that have no way to vent or displace that kind of heat.
Has anyone noticed how much hotter the kickstand gets? I bet you that it's attached to something the cpu is connected to. $5 bucks says we will see KICKSTAND HEATSINK + FAN MOD 2GHZ OC! LOL

This is a patch for developers, not a discussion thread for the merits (or lack thereof) of overclocking.
If you don't want to overclock your phone, nobody is making you.
It has worked out fine in the Desire and Nexus One community.

need to follow the directions in the first post. the .c files need to be loaded into the kernel source (right now just have toast's soruce) and the kernel has to be compiled with them.
if somebody wants to compile up a kernel with these, we could start testing. if i get some free time i'll help out here and compile a kernel but somebody else will prob beat me to it!

please someone let us know how this works out for your evo 4g... benchmark, test results... anything to show better/worse performance, whether your got ALOT warmer, or just a lil, etc.. ne information would be greatly appreciated it, i'm not a 100% noob, i just know how to follow instructions very well, doesn't mean i understand everything that's going on, just the basic concept of what i want. thank you in advance.

I'm waiting for someone to compile this first.
If nobody steps forward, I'll make my own attempt, but I'll be working blind with no test hardware.

I'm pretty sure most devs are waiting on the htc source kernal before playing with this. I can't wait but I understand them being hesitant to do too much with this for now. Still awesome of you to post it and have it rdy for when that time comes!

[Tiamat kernel 1.4.1) Random reboots on Xoom

Hi all,
I've been having random reboots/freeze-ups ever since I rooted.
This happens regardless of whether I am OC'ed or at 1ghz. These reboots tend to happen when watching Youtube or when browsing.
Would just like to have a feel of the ground if any of you who are rooted experiencing this?
Maybe we can start off by stating the following:
Kernel:
Clock Speed:
OC app: Setcpu or Droid OC
Governor setting: Interactive, on-demand etc..
Last app you were in that caused reboot:
For me, I am on the following:
Kernel: Tiamat 1.41
Clock Speed: 1ghz or 1.2 ghz
OC app: Setcpu
Governor setting: Interactive
Last app you were in that caused reboot: Youtube, browser
Im not sure if this thread shld belong here but since this is Dev where most of us root and OC, I thought I'd ask it here and hopefully we spot some trends with regard to the reboots.
Pls dun flame me Thanks!

wrong section

Moved to Q&A.

I have the same issue - Canada WIFI version

same problem, Canadian WiFi Version.
Not sure if it's because I flashed 1.4.0 then flash 1.4.1 to get the external sd card to show up. But I noticed after I got the external sd card to work, my usbOTG started working too, but from what I've read that should have been removed in 1.4.1 for stability issues.

Same issue. Using the tiamat kernel. It happens with different apps so its not any one for me.
Sent from my Xoom using XDA App

Switch to Droid oc and delete setcpu. Worked for me. Interactive. On demand is junk on Xoom. I use on demand on DroidX.
The kernel will Max to 1504 causing reboot (on some Xooms). Some device can't handle 1504, mine included. Superuser will throw up an occasional user permission for Droid oc as it brings the MHz back down to user setting.

I was experiencing random reboots with the same kernel, mostly just browsing in Dolphin HD. I first stopped OC in setcpu but the reboots still occurred. Then I uninstalled/reinstalled Flash 10.2 and cleared Dolphin's data.
So far, it seems to be much more stable and even battery usage has toned down.

This shouldn't have been moved to Q&A. There is enough discussion at this point on this exact topic that it needs to be addressed. There is a serious problem with the over clock in the tiamat kernel and/or the software that is supposed to govern the overclock. The developers here work very hard for all of us to get the most out of our devices and I fully support them in their work, but we are putting ourselves at risk. It is my understanding that SETCPU and Droid Overclock are only able to govern One of the Dual Core processors while the other is overclocked all the time. There is a widget in the Marketplace (Temp+CPU V2) that will enable you to monitor your clock speeds.... See for yourself.

I installed temp+CPU and don't see two cores. Only one display for MHz and it cycles from 216 to 1200. Is there a screen I'm missing?

This is right where it should be... Development forum is for developing...Discussing does not go there unless its in a thread where something was developed...The tiamat crew knows all about it...they did not make the overclocking, they used someone elses, and are about to remove out. And yes you are correct on the 2nd core.

Remove it? So no more overclocking? Can't a ROM allow OC and voltage control? But I guess it always comes back to the lack of source code.

Kernel source is available. It's the rest of Honeycomb that isn't.

So what is the best resolution to the problem? I get at least 5-6 reboots a day...I dl'ed Droid OC and deleted setcpu.

I had a harder time getting it to reboot with Droid OC so I think that's your best solution for now.

[REQUEST] Kernel W/CPU & GPU OC

I was browsing the Optimas 2x forum today and ran into an awesome kernel with GPU overclock. which sounds pretty cool to me. also the dev mentioned something about overclocking "system bus" which improvers memory/2D/3D/etc. i think someone in this forum should take a look into this KERNEL and try letting us taste some of this goodness.

G2X

CPU overclock is something that makes sense for us right now but what would a GPU overclock get us? To me thats just something that will lower the life of our phone with no real reward until games come out that our phone can't run. Right now our phone can run pretty much all games at full speed.

gpu overclocking would be sweet... now my question would be has anyone tried to load Optimas 2x kernel/software on the g2x since they are pretty much the same hardware(in theory you would think it would work)... i might even try to load this kernel onto my phone when i get home from work so if i mess anything up ill have my gear to fix it

I remember reading a while ago that GPU/System bus overclocking was attempted by some kernel dev, then later on, the dev realized through extensive testing that GPU and system bus clocks were locked, the changes to the kernel source had no effect (hardwired). Now this was a few months ago when I was reading up on Tegra kernel development before I got my G2x. Now all these could have been obsolete, and maybe now someone has found a way to do the above via kernel source updates.
Another issue that most people don't mention here and many people have been guilty of, is the GPL issue. The guy who supposedly did this overclocking has not published his kernel source code anywhere (GPL/XDA rules issues), so no one can examine what he did and prove that it worked....

Someone in another thread tried this and it messed up their baseband. A restore doesn't fix it apparently.

Big rush dog, the tiamat kernel guru and Guy getting engadet headlines for oc the xoom to 1.7 ghz has gpu oc in his kernels. I will be honest though, I can't tell the difference except maybe video streaming works a little smoother. I personally don't think it is worth the devs time...

Howdy! I'm the developer of that kernel
To be honest the GPU overclocks aren't all that beneficial. There is a little bit of a speed bump (I managed to get the highest score on nenamark2 for example). But the difference is was 27fps vs 32fps. If someone is interested in incorporating that into the g2x I'll be happy to show them the changes I've made. I haven't released the source because I'm lazy but there isn't too much to it.
Actually, if you look at the voltKernel sources for the O2X you'll see the same changes there.

Yes, superficial benchmarks like quadrant can be pushed to 5400 only with max cpu oc.
However, did you notice how 1.2 thru 1.5 gets you the same fps with no added benefit than more heat created?
Pushing other things other than cpu should let us remove bottlenecks and not tighten them up.
If you want your G2x to life 20yrs, 1.5ghz is not the way to go.
I have no kernel ready for release, to notice changes, I stuck to 1.5ghz, but the final result will be more likely 1.2 or 1.3ghz.
Maybe with a "don't hold my hand, give me freedom or give me death" DBU version at 1.5Ghz later.
I'm not shy to increase vcore on a SoC. But unlike the Nexus S, this thing gets HOT, fast.
Avetny pointed out that thread, I'll see if fallout hit something I have missed so far.
The clocks get compared to chip defaults in many places, choosing the smaller of the two, so it's just tedious replacing them with sane defaults, unless I stick to my current approach of offsets instead of absolutes.
We'll see.
That's also the reason I don't update my kernel often. Right now commits in cm git are only preparatory, config changes that made things smoother I already used.
I'll release something if they finish their version of BLN.
Or if I'm happy with gpu/bus/ram oc/tweaks.
not going to make people flash a kernel for no reason. As jlevy can attest, kernel not following cm git, not even based on it can work very well.
Not having latest cm commit on kernels that take another approach is not always useful.
Especially if we track regressions that cm devs back out later, that's all this gains.
So yes, there will be a gpu oc, when it's ready.

Great!
@ fallout0 thank you i hope that you can help out one of our devs on this.

You should talk to Fallout0 he seems like he got past the system bus/GPU locked issue. both of you can maybe learn something new from each other. & it would be awesome if the both of you can work on a kernel together.

Wouldn't a higher clocked G2x cause more heat? Heat being the reason this things reboots so often? Maybe a slower G2x is the way to go.

Would overclocking the gpu help run nds4droid any better? What else would ocing the gpu do? Everything seems to be very fast as it is lol

Pushing cpu more I don't see useful other than keep up with your buddy's Nexus S' quadrant scores and make sure your hands stay warm in a cold Chicago winter.
I build kernels usually when things stutter or otherwise annoy me. The pushing the OC usually comes by request of those who just want more more more.
I do like to remove bottle necks.
The hardwired clocks. Well the.cpu ones are hardwired too.
The gpu/bus oc works, until boost and throttling kick in, where again values are compared to hardwired values. using offsets after the comparison would be the way around without killing boosting and throttling.
Guess main thing that stopped me is the heat at 1.5ghz, and the frowns over 1.2ghz and 1.3ghz kernels, without further "what else is in there"
Still hoping fallout can share what he/she has, it'll help making this a reality, sooner.
It's tedious. Most of all.

Overclocking - pros & cons?

Yes, I FINALLY did it!!! I overclocked my G2X. I would appreciate if anyone could share their experiences with o.c. pros and cons... Should I retreat or stay where I am? Please some feed back!

Over 1300 seems to cause trouble on mine.

i dont think oc'ing is really that necessary with a phone this fast but if u must i wouldn't go above 1.3 (just seems unstable above that). I think the "Pros" come from being able to underclock. Setting up profiles for uc'ing when screen is off or as battery level drops etc really prolongs the life of the battery (at least in my case)
On my OG droid that came limited at 550 mhz, ya, oc'ing was def necessary but I cant really think of any "Pros" for oc'ing this phone.
each phone is different though so play around and you'll find a combination that works great for your phone, good luck

Well... you can get some serious bench scores... This thing rocks the Mandelbrot multithread test in smartbench 2011 at 1.5 ghz. Other than that it helps with games.

What about the CPU not having enough cooling and frying the CPU over time. I presume its just like Desktop overclocking but without all the extra cooling you can add to make it safe for the hardware.

But what i really want to know is if oc could damage the phone. After all if there is that danger it's noy worth it...

In all honesty I used to be really into benchmark scores and OCing the heck out of my phone and under volting it in the process but that led to many battery pulls ect. What I've noticed is just keep it at stock and mild uving seems to be the best for me its stable decently fast just 2 cents though

Overclocking a cpu is the same as on a pc, only a bit more dangerous on a phone. (This phone already has overheating problems running at stock speeds ) On a computer, people pay a premium for parts that are easily overclocked, and have either very good fans/heatsinks or a liquid cooling rig.
Overclocking is dangerous, especially because not all chips are going to be made equal, even if they come off the same production line. These chips are designed to run at a certain voltage, and certain clock speed. As far as real world use, (NOT benchmarks. Sure, they look pretty and all, but benchmarks are never very accurate.)
Sure, you might get 2-3 more fps on your games, but is that worth the risk of shortening the life of your chip/phone?
(And just so you know, I've been building/overclocking pc's for years, but I also understand what you need to do to keep it stable, and it's *all about cooling*.)
If you're not convinced, try this. Don't overclock your phone, and use it for a few days. Tell me honestly that you really notice a real-usable difference with the chip overclocked or not. (Games set aside, but like I said, getting a couple extra fps on a game to me isn't worth the risk without a proper cooling setup)
For those of you that really don't understand what you're doing to your chips when you overclock, I'd suggest doing some reading about it. A good place to start would be here: http://en.wikipedia.org/wiki/Overclocking

So you think using fauxs kernel is not safe or reduces the life of the chip? I just flashed it and didnt oc or uv further then fauxs default settings...

I'm not saying it's for sure, I'm saying there's a chance.
Plus keep in mind that these kernels have other really nice additions besides overclocking and undervolting. I'm using faux's stock voltage kernel ext4, and leaving it at stock settings, and it really works great.
I just posted this up because I see a lot of people more interested in quadrant scores (which to me are pretty useless) than stability of their phones. If you do overclock, and it works for you, more power to you. I just want to inform people. I'd HIGHLY suggest if you aren't sure, read that wiki article, it's a great place to start. (not all information is there, but it gives a very good general idea on how and what overclocking is.)

Thanks! i always like reading knowledgeable and informative posts!

OK, you definitely convinced me.... I have also faux (let me tell you exactly - Kernel Version 2.6.32.9 FR Faux 123-v0.03) on EagleBlood 1.05. Could you please tell me what I need to do set up in order to be safe? Thanks!

I'd just go to faux's thread in the development section (his froyo thread, not the cm7 one, since you're using eagleblood), and download his stock voltage kernel. (It's in the first post.) He's on .04 now, by the way.
Then reboot into recovery, and flash the file you downloaded. It'll overwrite your current kernel and modules with the new one, then reboot.

You passed right by it. LGE stock froyo. (That doesn't mean it's a stock froyo rom, it means it's *based* on one )

Choose the stock voltage one. (ext3 or 4, depending on your preference.)

And a lot of times the kernel will be credited to the developer. So if you see "faux's kernel" people are referring to kernels by faux123. Trinity kernels were developed by morfic. If you are having a hard time finding a specific one, look at the top left to see who started the thread and sometimes that will help find it. Does that make sense? I had to pull an overnight at work so I am a little loopy....

Constant reboots when overclocking

I'm currently running CM10 Nightly + Air Kernel r211
and I've been trying to overclock my NS for a while now with NS Tools but I keep getting reboots.
I've tried 1200mhz with SmartassV2, Ondemandx, Ondemand, Intellidemand. With vr, noop or deadline schedulers...
Nothing seems to work.
I can't seem to find any guide on how to properly tweak the voltages without damaging my phone?
Any help appreciated.

Surprise! Overclocking can lead to instabilities. Read on overclocking as a whole, and overclocking on Android phones to understand the concept and why you are getting these results. Overclocking isn't a warranty you'll be able to get a higher frequency, all phones are different and someone phone might be able to overclock a lot while another one not at all.

Not helpful, buddy.
Anyone else?
I'm going to try Marmite 4.7 kernel (seems to be more stable with 1.2 OCing). Will report back.

Actually very helpful. Do your research. There's no magic to overclocking, one settings aren't useful for someone else, if only as a starting base. Trial and error until you find something stable.
Once again, all information can be found using the magical search function and your old pal Google.
Edit: Also as a free candy, governor has jack s#%! to do with overclocking.

You're not the judge of saying if your ****ty condescending replies are actually helpful to me or the community.
I am telling you that you are not being helpful by acting obnoxious and telling me to do my research when that's what I have been doing for the past 2 weeks.
Please stop posting unless you are going to be actually helpful.
ANYWAY,
I have just updated to latest CM10 nightly and flashed Marmite 4.7V. OC'd to 1.2Ghz without touching any voltages. So far so good! Opened a few apps and played around a couple of games. No reboots yet!
I can say that Air Kernel is pretty unstable with any OCing. On my phone (i9020A) anyway.
Hopefully this thread will help anyone else searching for OC stability with custom kernels.
I will keep updating if I encounter any problems.

Update:
I am experiencing much better performance! Real happy with how smooth Marmite is, and very stable with 1.2Ghz.
Absolutely no lag, no failure for launcher/drawer. Games run smoother. Chrome browser is actually faster.
I am using SmartAssV2 Governor with Deadline scheduler.

So for the past 2 weeks you have been researching but did not know governor had nothing to do with overclocking, or haven't found good voltages to start with?
You run a nightly to test overclocking?
You my friend, are not only a moron, but you have done a very sad attempt at stepping on someone's head to excuse your indolence. These forums are chockful of information regarding overclocking and there's quite a few posts with NEARLY global voltages for the Nexus S phone, both INT and ARM. They do not guarantee you a stable overclock but offer you a good base to start with. Taking a few minutes of your time you could also go and check the sources of the many kernels that offer/offered overclocking (Matr1x, AIR, Marmite, iNK, Trinity etc etc) to see what voltages they have set for different steps, once again to give you a good eyeball figure.
Do yourself a favor and keep your mouth shut if you're only going to spew garbage. Have fun with your one click software.

Actually, he was pretty helpful. Why you have to dog on him for an answer that's spread all over the internet is beyond me. Threads like these do nothing for anyone when there are already boat loads of answers spread all over the internet. Plus, it took you all of two hours to try a different, much more stable kernel to solve your problem.
Edit- I got beat to reply. Either way, my response still holds merit in my eyes.

Nope not helpful at all. The answer is not spread all over the internet or these forums, as I've been trying to search for them for weeks now. Both of you are hilarious morons. You keep showing off and acting all 'know-it-all' but none of you have actually linked to any helpful source/thread explaining or describing the things you're bragging about.
Telling people to 'search' around and stop posting threads doesn't help the community. I posted the thread about something that I was not able to find an answer to by searching in the forums or on Google.
Now instead of arguing like a bunch of idiotic 5 year olds, I challenge you to link me to a thread that clearly explains custom voltage tweaks or a guide that has instructions on how to properly overclock the Nexus S.
Also, having "PLEASE PRESS THANKS IF I WAS HELPFUL" in your signature is absolutely pathetic. Grow the f' up.
