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

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.

You can try tegrak from the market if you really want oc.
In all honesty, just wait for a kernel to come out that will actually oc. I'd love a kernel that uses voltage control and will wait for that...
Ahh, thanks. This is my first android device so I have no idea what to expect and when
If I can ever get my config straightened out, I was going to look into doing an OC kernel that uses Voltage Control, similar to nemesis2all's kernels for the Fascinate. Still trying to get a working config though.
My opinion though is that OCing the hummingbird processor is useless, and does little for performance on a day-to-day basis and only serves to give you big numbers in benchmarks while reducing battery life.
I mostly used the 1120 step skipping 1000 and scoring serious uv was awesome
Howdy folks. Could someone point me in the right direction? Thinking about overclocking but have not done it. What are the benefits / rewards?
Is there an app or program i can to do this?
And what is a safe range?
Thanks in advance!

Benefits : Faster phone, smoother ui
Cons: Phone may heat up if overclock is set too high
For this phone 1500 is the highest, safest number we can get to right now. I would suggest setCPU, which you can find on XDA for free. (search setCPU)
You'll need a new kernel first, the stock one doesn't support oc. Go with Faux's assuming you're running a rom compatible with it (and most are).
After that, download Pimp My CPU from the market and you're good to go.

To be honest with you, I notice hardly, if any, real-world phone speed increase when I overclock...barring benchmark numbers. I'm not really sure why that's the case for me, and why for some others it's such an extremely obvious difference (or so they claim). Perhaps I'm not running the same cpu intensive apps that they run. But for general, day to day, running of my phone, it's just not worth it for me due to the battery cost.
So I would love to hear from some of you where "precisely" do you see such a marked improvement on the speed of your phone?
Well, first off, make sure you have a custom Recovery installed... Then find a ROM you'd like, and then, flash a custom OC Kernel..
You'll need an app such as SetCPU to control the overclock.

Are you using the stock launcher? It's alot smoother with the stock launcher if OCed to 1500, although i don't notice a difference from 800 to 1500 on launcher pro.
As some of you might know, the HTC Desire S overclocks very well.
I've done alot of research, and I've found no difference between the MSM8255 chipset our Desire S runs on, and the higher clocked MSM8255T (which runs at 1.4-1.5GHz).
I've created this topic to gather some information on what method you use to over/underclock (built-in, custom, app etc), how high you've clocked your device, what governor you're using, and what temperature you're at.
Right now my Desire S runs at 1.4GHz, incredibly stable, ive stress tested for hours (so far) without any errors, maxing at bout 36,5c temp.
My current method is SetCPU, using 245-1401 interactive scaling.
Please post your findings / preferences / device settings.
I never overclocked my Desire S. Ok sometimes he can be slow, but I don't like overclocking a CPU of a smartphone... Maybe it's because I'm scared to blow him up or something, dunno. I just leave it like it was, in my eyes, the best thing you can do
I'm using OC/UV Beater2 which came in Endymion ROM. My DS is overclocked to 1,2 Ghz and it is very stable, never freezes
But I have a question, what is default undervolt settings? Because I think when I set for example -25 undervolt settings, that will come default setting after a while..
So I dont know what is default voltage... So if someone could tell what is though 122Mhz voltage, I would be happy!
1ghz ondemand. Sometimes 245/768mhz and in games 1.2ghz

Yeah, I've done some research too, and cannot find any differences about the 8255T vs 8255.
Ours are highly capable of going to 1.8Ghz stable.

Same CPU 'issue' with the Arc and Arc S ->
http://forum.xda-developers.com/showthread.php?t=1396071
That pretty much sums it up, why the Desire S (some - mine?) overclocks so well..
Same thing they do with desktop CPUs.
Like my old C2D E6600 2.4GHz OCs to 3.4GHz without adding volts and running only on air cooling, 48c after 10-12hrs of stress testing with SLI nvidia cards in the case.
All in all, the MSM8255 and MSM8255T could easily be the exact same chipset/CPU, just at different speeds, some tested more extensively than others.
Has anyone tried running speeds above 1.5GHz+ successfully? 1.5GHz should also be doable, as the HTC Flyer has the MSM8255T and runs at 1.5GHz.

My Desire OC's very well. I can go to 1.8Ghz stable for very long.
(I don't usually OC though.)

I have overclocked my phone to 1.5GHz almost all time and I do not see any problem, it's very fast and snappy. I use Sense roms, CM7 and ICS without freezes or something like that. Battery life is nice for me, 1 or 2 days of use.

Hi there,
Yes I use setcpu. Tiamat kernel is Undervolted by default which is good.
I'm my experience, I'm getting much better battery life with Tiamat kernel.
Are you on the nightly build or the stable version? I heard a few issues with tiamat on nightly builds, but not too sure!
Also a small note; undervolting doesn't help massively with battery life... the battery gain is minimal. On sense based ROMs, I UV by about 125V and it doesn't make a HUGE difference.
I think tiamat has really good battery llife as it has been exclusively optimised for our 8255 CPU by the brialliant Devs
Hope this has been some help to you!

Reason i'm asking: on lowveld's hyperions i got 8-9mA consumption while idle, on CM i'm always at 10-15. The min freq on both is 245mHz, which was suggested as lowest stable so the next difference i thought could be the undervolting... From battery stats i see that phone was not awake...

What bug fixes did the nightlies bring? Please share!
Hmmm... I guess you could just wait for CM 7.2, I think its coming very soon with the bug fixes, so I guess you could go back to stable from there, and use Tiamat.
My lowest CPU clockspeed is 184Mhz on CM (122Mhz on Endymion)
Its very stable for me. No freezes, etc
I use smartass2, so it will throttle up the speed in sleep if 184mhz is too low. When it has many tasks to load etc.
Not to sure how to Manually UV with CM, (as OC beater doesn't work - FC on me)
But on Endymion, OC beater app does the job.

Hello,
I just installed the ressurection remix 1.5 rom, in combination with Thoravukk kernel, and i set my cpu to 1.6 ghz.
Set it at boot, and rebooted the device.
I'm really impressed about the boot speed, and overall smooth scrolling etcetera.
My question is, is there something else i need to do to keep it stable, or change other settings, like voltage, gpu, ram or anything else?
Because i'm really happy with the changes it's given me, but i don't want problems in a while.
Batterylife is not an issue, i don't expect it to last as long as it did on 1.2 ghz
Looking forward to information.
If i don't need to do anything else, i would like to know as well.
Thank you
Lost in space xD
Can any one help me with some info on where can I download the Thoravukk kernel. I've entered around 3 or 4 (including the official team blockbuster) sites and I don't see any download links
Why do you have it overclocked to 1.6? is there even a difference in performance? The phone's so powerful already lol, you could UV for better battery life, increase gpu for performance (in games) I don't think you need more Ram, I have the OG epic 4g and I have plenty lol
As far as stable, pushing your processor may create problems that you won't necessarily see at stock frequency, you get what ask for.

Exactly what I had in mind
The Note is plenty powerful even amongst the current crop of droids. And no app requires a dual-core 1.6Gghz. The stock frequencies were chosen for a reason, I'm guessing it's quality. All chips burn out in time, they have a lifespan. But you overclock your device and you burn your chip faster.
So what I'm saying is stay with the original frequencies. Port an optimized ROM and that should suffice.
Thanks for your answers, but i really notice the differenct, especially with a reboot, it normally takes 30-40 seconds, and now in less then 10 secs i'm at my home screen, and ready to go.
Also it is smoother with scrolling, and apps launch even faster.
so the diff is hugh to me.
Battery life is not an issue, i said, even if it goes to crap, i replace it for €20,- (Just about $25,-)
And the performance is nice, but my question was if i have to set other things.
And i use lulzactiv governor, it uses only what it needs, it's not always the full 1.6 ghz. Only when speed is preferred.
