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!
sounds good.

Your signature says you have a radio of 1.32.651.6, just to let you know that is not a radio, that is an HTC software OTA update. My radio is 1.39.00.05.31 for example
So after many tries I got SetCpu working, granted root by SuperUser.
Uploaded with ImageShack.us
Of course, the CPU frequencies are not automatically set by SetCpu, like it use to be for the good old 1ghz single core Snapdragon.
So what frequencies could be tried without riscking much for the CPU?
Does the Sensation kernell allow overclocking?
I couldn't find any answer for these 2 questions concerning the Sensation, sorry if I missed something or didn't use the search fonction correctly!
(noooo, please, not this "you're a noob at XDA" video!!!
I would wait till you can flash a OC kernel made for the Sensation. You can try going up small increments if you wanna try it. If it was me, I'd rather be safe than sorry
..plus I'm pretty happy with the speed right now. But when that kernel comes out, ill be OC'ingOC'ing too
right, I'm mainly gonna try to save battery using SetCpu using its profiles.
Problem here: SetCpu works only as long as I don't stop it and start it again. I mean I will get root granted only once, after I've used fre3vo and rootsh via adb

Well, you would need a custom kernel made for overclocking to start. Set CPU can crank up the Mhz that is already there, but its not gonna go over 1.2ghz.

i havent tried, but common sense says "no". im pretty sure setCPU wouldnt support our processor just yet, especially w/o full root access. and really, the risk compared to the payoff is minimal...for now, its nice to know it works, and is good for monitoring, but just wait until all the pieces of this phone fall into place

m8 how did u get set cpu working on sensation? do i have to create manually a setcpu.txt? if yes what do i have to write in there?
Hi,
this may be a stupid question but I'm owner of a xoom for 1 week now (got it pretty cheap on amazon cyber monday) and am actually quite fond of it. To my question:
I'm actually quite surprised by the user experience on 3.2, it's very responsive and fast so I'm asking myself if rooting is even necessary? Also looking in advance to the official release of ICS, which is supposed to come pretty quick for the xoom.
Is it worth it? If yes, which ROM would you recommend?
Thanks!
overclocking is worth it. most of us run rock solid @1.5
not to mention all the other things you can do...
I agree, rooting and using custom roms and kernels adds lots of functions that you otherwise wouldn't have, like being able to write to the micro sdcard and using usb host mode.
I love the setup in my signature and highly recommend it.
There is the expected ICS update, but I think it's still months away. Our developers are working on ports of ICS as we speak, so chances are that we might have it in a custom rom before the Xoom gets the OTA update.
Then that's settled. Thank's for the help guys!

hi okantomi,
i use rooted xoom but i dont do overclock due to battery drainage. Is it true that more you overclock the device more your battery drains? I am confused. I want to overclock and again want to save battery. what can i do? plz help.

yup OC = more battery usage.
if you OC with setcpu you can use profiles and set the clockspped to batt level,temp...
Profiles work really well to save battery under certain scenarios, also you can undervolt a bit to save battery...you will have to experiment a bit with that though, too much undervolting won't support the clock speed you have it set at...(do you follow?)...there have been a couple of good threads on this topic.
Hello all, i rooted my tab today. Installed Superuser, Set CPU and Titanium backup. I froze a few of the pre loaded Samsung apps that came with the Tab. What other things can i do to speed up performance now that i am rooted? Any suggestions?? Thanks!
(Also if anyone else is currently using Set CPU on their Tab7 +, what settings work well for you? )

Which model? (There are at least 4 different ones.) Are you willing to give up battery life for that speed? What do you want to use your tablet for?

I have the Wi-Fi_GT-P6210. I guess my main issue with Set CPU is what are the limits i can go to without locking up the device. I have Set Cpu on my EVO 4g so i am familiar with it. I guess i was just seeing what advantages rooting gives me. I have my EVO rooted so i know the benefits on my phone, but what about the TAB. What apps can i remove without effecting performance. Thanks
If you want to overclock or undervolt, you'll need a custom kernel (see my sig.) At that point, you can OC to 1.4GHz. (I didn't include support for 1.6GHz has the processor in my own 7+ wouldn't stay stable at that speed, so I can't test it properly - it was also extremely easy for me to only add 1.4.) For voltages, you are also kind of going to have to experiment. I'm stable with 1300/1225/1125/1025/950/900 on my tab plus, but I can go much lower on my SGSII (which has the same processor.) You can search on the SGH-i9100 and SGH-i777 subforums for what other people have done with voltages.
As for which apps can be safely frozen, there's a post or two on that from a couple months back... I'd suggest searching for the full list. Nearly anything that looks like bloat really is.
I'd never suggest actually removing stuff - much better to just freeze it... then if you figure out that you really needed it, it's trivial to defrost it.
Good luck
Gary
