Hey everyone, there is an overclocking app in the market, anyone care to give it a try?
Edit: So I downloaded it lol. Here are some screenshots. BTW, is there anyway I can verify that the cpu freq is actually being adjusted?
*Just for fun I ran neocore to see if it would raise my FPS. lol.
just notice the difference in speed. If you notice please post. And its not overclocking its just clocking. Overclocking will be beyond 528 MHz

The app is called Overclock, you can argue with the developer about the name not me.
Anyways, I do notice a very nice speed increase.
For example, atrackdog would take me at least 20-30 seconds to load my full app list (184 apps)
After installing overclock, it loaded in under 5 seconds.
i'll run other programs, and post my results.
I ran droidgear (game gear emulator) before and after, and I can honestly say it was faster (not a placebo affect).
-Before: droidgear would take over 4 minutes just to get to the menu screen
-After: i was actually able to load a game in under 1 and a half minutes, I even let it sit to run the demo, and it is the fastest ive ever seen an emulator run on this device (compared to NesEmu, and GB emu)
It would probably actually be playable if tweaks were made to the application codebase, and android Open GL stack.
Also, the camera loads instantly after pressing the camera button and via the icon in the home screen.
well, i was too, and then i downloaded it and said "aahh, what the hell, if i break mine, ill just take my wifes haha..." probably not the best of plans but i installed it anyway
sooo i havnt burnt up my phone yet, but here is my issue with the app, does the app only work untill you reboot your phone?
because when i reboot my phone, it goes back to the default speed according to the app
also, my phone tends to hang up (stuck on the apps screen, no buttons work, screen wont rotate, power button wont shut screen off) when using the 528MHz
so far, i havnt found a reason to pay a dollar for it, but ill keep testing
[UPDATE]
resolution for all below tests is 320 x 480
i tried neocore like posted above, using the mid level setting, and i actually did raise my fps from
DEFAULT CPU (248 MHz): 20.5 (with sound off)
384 MHz: 25.0! (with sound off)
DEFAULT CPU (248 MHz): 14.5 (with sound on)
384 MHz: 20.8 (with sound on)
still havnt gotten the fast speed to work yet, but im still trying to figure that out, on another note, sweeter home does seem to load a little faster
[UPDATE]
Incase you didnt see my sig, im not running on a ADP1 phone, so that might by why the fastest setting doesnt work for me, but so far 384MHz is making a noticeable difference with NEOCORE and SWEETER HOME

i use snap photo, which used to take FOREVER to load up on my g1 using the camera button, its significantly faster using the 384MHz setting, good observation
Ok, so so far here is a list of things ive noticed (using 384MHz vs 248MHz):
-FPS in NEOCORE increased on adverage 5 to 6 fps
-Sweeter Home doesnt lag NEARLY as much as it used to (ALOT less force closes)
-Snap Photo doesnt take a month to load using the camera button
-G1 Wakes up properly which was a issue my g1 (and others on this forum) had
-Even though the app says it will "kill" the battery, using 384MHz during normal use of the phone isnt "killing" my battery, however, doom (while runs better (even with sound on)) seems to be dropping my battery level faster, but the game is running faster, which is the trade off id expect when running these apps together
At this point is there really a need? My phone doesnt lag that much that I need to over clock not to mention my battery life sucks already.

all of our battery life sucks unless you have the extended battery, im not getting THAT big of a battery drain according to the system monitor app, and it DOES make a difference on g1's that have lag issues (running tons of apps like i do)
in other threads, people have complained about the g1 not waking up quickly sometimes, ive yet to have that issue since ive clocked mine up to the 384MHz setting
@woot, you do know that the default cpu freq on the G1 is ~384mHz. So you might want to change in your sig that you're overclocked to 384mHz lol.
The program installs a script on your sd card called ocx_tmp.sh and adjusts it that way, it'll write to /system as -rw (from what I've discussed with someone) would probably cause instability.
The program will reset the cpu freq back down to 384mHz after the phone sleeps. You can verify this in terminal emulator by typing:
$su
#cat /proc/cpuinfo
Try it before and after setting the cpu freq in overclock and you'll see what I mean =)
I thought the the CPU ran at 528 MHz by default? Or is it clocked dynamically and this forces it?

im not as familiar with clocking/overclocking so i wasnt sure if i was clocking it to 384, overclocking it to 384, or what, so what would be the proper thing to put in my sig? lol because according to my first quote, true overclocking wouldnt be untill i went beyond 528, so from the view of my first quote, im not OVERclocking, im clocking, wheras your saying im overclocked

so is it infact the program thats changing the cpu freq or is it the phone? if its the program, is this to avoid overworking the cpu without the demand?

by sleep do you mean turning the screen off using the power button? because i saw no change in my cpu freq when doing so using your commands

I remember reading somewhere by someone that it runs at 384 by default, and I think the post above confirms that...

no, it runs at 384 by default, and clocks down even lower in the idle loop.
i am curious how this program works, as the normal cpufreq interfaces are not compiled in the kernel.
i've been running my phone for several months now at 528mhz, at a fairly minimal detriment to battery life.
i did however notice that without modifying the idle loop, the amount of cpu frequency switches even while the phone is not sleeping drops your average clock within a 10 second period to somewhere closer to 400mhz.
after modifying the idle loop to not switch frequency so often, i was able to get 27.4fps out of neocore w/o sound, and 22.7fps w/ sound.
my overall caffeine benchmark score was 582.
battery life impact is there, but fairly small. phone lasts for about a day and a half now where it used to last for sometimes 2. under heavy use, this is of course dramatically reduced.
gui fluidity is definitely increased, and sluggishness between app switches and when the translucent app drawer opens up is gone. i like it, but to the average person there probably is no need to do it.
keep in mind this is also not overclocking the cpu, it's clocking it to its default spec. as it is an embedded arm, it is designed to run hot, so i guarantee you are in no danger of hurting your phone.
also, do not listen to people that claim there could be no gain from overclocking, just because the bus speed is slower than the cpu speed does NOT mean there will be no improvement in system performance. if that were the case, there'd be no use for 4ghz desktop processors.
cache still runs full speed, and common execution paths stay in cache meaning no prefetch from system memory, meaning BIG improvement in many cases. (that's why cache exists.)

gui fluidity and responsiveness is greatly improved. sluggishness if app switching and the translucent app drawer are completely gone.
for many i imagine this means there isn't really any reason to clock the cpu up to its stock speed, but to each their own.

care to write up a how-to for getting the 582 consistantly and changing the idle loop?
Holy crap. Used this @528MHz with Haykuro's version 4.5 apps to sd ROM and the osk works SO MUCH BETTER!!!! Also I got 25.6 fps on neocore... very smooth

writeup? no. it's a big process involving the android dev environment, a modified version of mkbootimg and unyaffs.
i will gladly post the kernel modifications for those who want to recompile the kernel to do so.
the bootloader sets the clock speed, and the idle loop simply clocks down to a preset and back up to whatever it was previously after x milliseconds of inactivity (not to be confused with sleep) it's kind of a poor man's cpufreq arbitrator.
so on top of tweaking the idle loop to not drop down as often, you also have to explicitly set the frequency in the kernel upon bootup, or it will bet set at what it thinks is full speed, which is 384.
A modded version of JF's ROM would ROM.
I DO notice the sluggishness and it bugs the heck out of me. (I switched from a WING with a 200MHz CPU, and although it IS faster than the wing, it doesn't seem significantly faster and seems to much slower when I open up the camera...

that involved eh?
thanks for this post though, now i understand more about the idle loop and why the cpu freq resets with each reboot
maybe someone can take this stuff further like he said, that kind of stuff would be worth the dollar, imo more than a dollar
well... i don't mind providing basic procedure and source, i just don't want to get dragged into level 1 support of the procedure.
i'll go ahead and package up some source, prebuilt boot images based on JF's RC33 (which is what i run) and a basic procedure.

Screen Off: 245-480
**Stock is 245-245. 160 as a minimum seems to produce a LOT of wait time from when the call is coming in to when the phone lights up. More than 245 seems to whack the battery.
Keep in mind, when you wake up your phone, this Screen Off SetCPU Profile is active for at least a SECOND or two. The problem is that if you have your maximum at 245, you experience BAD lag trying to pull the lock bar down. At 245-480, the maximum is high enough that a) the lock bar pulls down as smoothly as a stock Eris, and b) even if SetCPU takes a couple of seconds to change the profile, at least you're at 480mhz for the first scrolling of the screen left/right (so you don't embarass yourself in front of iphone users). Anything higher than 480mhz is a different voltage. Almost the whole time your phone is 'Screen Off', it will be operating at 245 anyway. So 480 is a good setup for it to jump up when a call comes in (to play the ringtone and show the picture a little faster, and for the lock screen bar to pull down smoothly, and the first second of SenseUI to be smooth enough, until your phone changes the profile to your <100% profile.
Battery <100% 245-806
** Zanfur's take on how this processor clocks up/down its speeds will lend itself to a general wisdom that 768mhz isn't really slower than 806mhz, and that in instances of high variability of clock speed (aka you have some Power Save bias in SetCPU keeping it lower/higher at random, or you're doing very intermittent tasks), the processor rests at 768mhz more quickly, and wastes less time/'effort' changing speeds. Changing to 806 is another 'step' altogether, where 245 to 528 is one 'step', and that to 768 is another 'step'. Going to 806 is absolutely another step yet after that (which means your phone responds a LITTLE slower because it has one more step to 'throttle' up to). BUT, if you're doing a dedicated task, such as running a Linpack benchmark (which is a terrible benchmark anyway) your phone will move faster at 806, or if you're playing a game, or playing a video... generally the processor will stick at one speed (and not have to 'step' up or down), so 806 is faster. I clock friends' phones at 768 to avoid problems, keep it clean, etc etc. Some people put the minimum here at 160mhz, but I feel that this is too low (and another 'step', just like 806 is over 768, 160 is another step down from 245).
Charing (any) 480-806
** I keep the minimum here HIGHER than when the phone is on battery, because I'm less concerned about how much energy it's consuming, and having a minimum of 480 makes the phone very snappy no matter what, from the second you touch it
Overheating > 48C 122-528
** Clock speed here matters a LOT less than just getting your phone out of the heat. This phone doesn't overheat because it's overclocked, it overheats because you run it at an overclocked speed for a long time. MOST overheating instances are from wireless tethering and from broken charging systems (that keep trying to charge the battery and generate a lot of heat). The 'Failsafe' profile here provides a 'notification' option which I HIGHLY recommend.
My ex-gf's Eris actually CAUGHT FIRE, as in it looked like it was a zippo, right above the volume buttons. It used to overheat EVERY NIGHT that it was on the charger, excessively, so hot that you couldn't touch it. For a month or two it did this, actually, and caused no real damage to the phone. Since the night of the Flame (you can actually see the melted plastic and even on the outer case - she has a blue snap shell case on it that is melted as well), the phone has NOT overheated even one time on the charger. (Sorry for the story, it was a waste of time).
The point is that, the first time it happened, her phone System sound was on Silent, and she DIDN'T hear the notification that her phone was overheating. Apparently it doesn't matter (or she's very lucky her phone isn't damaged in terms of its operation!) how much it overheats for some people, but I like to have it warn me it's getting close to 50C. The notification's the important part there (so u can cool your eris), not the clock speed.
@pkopalek I like your settings you posted with a full description of each. I changed my settings to yours and give it a day or so and will report a status update as to performance quality
I've never lagged at 160mhz =p but that could just be my phones/ roms.

my audio skips and it won't wake up when in a call at 160mhz. I keep mine at 245mhz minimum to keep phone working smoothly.

How do you guys clock your CPU so high? Whenever I try anything over 729 bad stuff happens. If I put it on 748 it lags and if i try 768 it freezes up. You guys are all using the droid eris right? What ROMs and kernels are you running? I'm on Kaosfroyo

When a processor is made at the factory, it will always have flaws in it. The chip is tested to see what frequency it is stable at. So that is the speed that is stamped on the chip and the frequency that it is set at to operate for the consumer and not have any problems. When you overclock a processor, you are bypassing the frequency that the chip as been deemed to be stable at. After that, there is no set speed that your processor can handle, because each one is different according to the flaws it might have.
So in short (what I'm trying to say), the processor in your phone just can't handle those without causing problems. That's why when you overclock it, it's kind of a trial-and-error process to see what speed you can get out of it, but be careful, because too high can cause permanent damage.

I'm looking at the sys info on quadrant and it shows my current freq: 800mhz.
any one know why it would be showing 800mhz and not 1ghz?
Yep, because it fluctuates.
ahhh... saver modes then... thanks for the info..
now if there's a way to make it static at 1ghz
Why do you want it to run at full power constantly? Why do you want it to suck more power then it needs to?
Believe it or not, your computer CPU does the same thing. It's frequency fluctuates depending on the task at hand. Take this for example: my Core 2 Duo isn't going to always run at it's 2.5Ghz. Intel has something called CPU stepping in it's instruction set and it's meant to decrease power usage, wear and tear, and energy drain when at idle or near idle. Same thing with your phone.
Most people here probably knows that the higher the CPU clock speed is, the higher voltage the phone needs. Which means higher clock speed results to more battery consumption. This is very simple logic, and sure, in real life practice this theory is proven to be true.
One method that is usually used to gain better performance while not necessarily waste more battery is by overclocking and in the same time undervolting. Because there obviously is a certain level of voltage needed to run a certain clock speed, the normal practice is reducing the voltage level to a bare minimum level where the CPU can still run alright while raising the highest clock speed possible. Reducing the voltage too low usually leads the phone to shut off because there isn't enough voltage for the phone to run.
By following the theories above, we can conclude that to achieve the best performance while still considering battery life, adjusting the proper OC and UV level is needed. This is obviously only talking about hardware affecting tweaks.
We now know that the main factor affecting the overall performance vs battery life turns to be the clock speed itself. Now here comes the ultimate questions.
1) How does the phone handle its clockspeed?
2) Does the voltage level change according to; a) the current clock speed the phone is running at, or b) the highest clock speed set/allowed the CPU to go?
3) Does the highest clock speed set (OC) leads to necessary higher voltage, or does the voltage accostumize itself to the running CPU level?
The most logical answer to number 1 would be that the CPU changes its clock speed according to whatever is happening and needs to be done to achieve the best performance. So the clock speed will go up when there's lots of tasks, and go down again when there's little or nothing to do.
Number 2 and 3 I can't explain, but I hope after someone with enough knowledge explains how voltage level works, we can have an answer to the following case;
IF two same phones clocked differently, one at 1ghz and the other at 1.5ghz run the the same relatively simple task for a long time, will the lower clocked one noticeably save/waste more battery than the other one? Or will they consume the same amount of battery because they would most likely be running at the same clock speed (say, at 200 ~ 600)?
Hopefully we'll have a better insight about overclocking vs undervolting

I believe one would have to set each speed & undervolt up together if one scales the speed. I just run mine straight up at 1300MHz/1325mV all the time & set up profiles for screen off, charging, etc. I get wonderful speed & battery life.
Example:
1300MHz/1325mV
1200MHz/1275mV
1000MHz/1175mV
/800/MHz/1125mV
etc.
Each phone is different due to the variations in manufacturing.
The only way to really optimise your phone is to try all of the various settings and combinations of voltage/speed.
Set the phone to a given speed, stress test and try decreasing the voltage until you get crashes / errors. Then raise the voltage one level (or 2 if you are a bit paranoid) and that is the stable voltage for that speed.
Rinse and repeat for all other speeds...
Then set profiles in setcpu / pimpmycpu accordingly.
Job done.

I think you could lower your voltages quite a bit - eg Mine runs at 1.4GHz at 1.2V
Ok my friend... so... having designed a circuit for a mobile phone myself, I'll try to explain quickly what's the deal (tradeoff) between frequency and voltage.
A CPU/GPU basically is made out of MOSFET's (transistors). Lots of them! They act like capacitors. They have to be turned on and off. At a certain frequency. So, basically they are capacitors being filled and emptied at a certain frequency.
In practice, a capacitor being filled and emptied at a high enough frequency can be seen as a resistor. A variable resistor in fact, as you can see (more or less) here:
http://www.electronics-tutorials.ws/filter/filter_1.html
The thing is, the higher the frequency, the lower the equivalent resistance, because the amount of current keeps getting higher and higher. If the current value gets high enough the very tracks (you can think of them as wires) from the battery to the transistors start having a considerable drop in voltage (the resistance in these wires is supposed to be very low but it's not zero!). And if you have to much voltage drop on the wires the transistors don't get enough voltage to turn on/off.
So there you have it! That's the problem with overclocking. Voltage drop at the tracks (wires) because of increased current. You may also run into heat issues
Now, trying to answer your question, even at the same clock frequency a CPU that is processing stuff will use more energy than one that isn't "doing anything", because transistors aren't really changing state. But a CPU not doing anything at a lower clock frequency will waste less energy than another one not doing anything at a higher clock frequency, because energy is required to drive the clocking circuit itself. So it's very non-linear, you get the picture I hope

You're welcome!
Also, to complete the answer a bit more, lower voltage also helps with getting less energy consumption, because it takes more charge to "fill" a capacitor to, let's say, 1.3 V than to 1.1 V.
Most of your know about this problem. People complaining about phone heating, phone shuts down in the middle of gaming, heating while gaming with 90hz in all forums. But no one come up with the solution and Some even told us to send the phone to get serviced [yeah, but even then the service center will say that it is motherboard fault, which is the costliest replacement of all around 25k INR]
[NOTE: I want this to be heard by ASUS to release software update. If you are a moderator of any Asus forum or who could contact ASUS dev, share this thread with them]
First and foremost we have to understand what is causing the problem. And everyone who is facing the problem knows Its the Temperature causing the shutdown. But ASUS never implemented any Warnings to to the UI, instead they give active cooler to 256+ GB version, while leaving 128 GB owners stranded. I faced the shut down problem when updating to A10 around a year back.
Every time when I game outdoor on warm condition (around 30 degrees) and After few months of updates, it started to shut down very frequently. So I switched back and forth to custom ROMs and even to stock A9s.
Faced the worst embarrassment "Gaming phone shuts down in front of cousins who were playing in budget phone"
Finally my Gaming phone become a phone which cant game anymore.
Finding the real Problem:
After researching about android thermals and I even tried to stop the shutdown from happening to my device. But I failed and my device successfully shuts down when there is a chance.
I switched to custom rom and installed GCAM. On taking few photos, my phone died. After restarting and enabling the CPU overlay which shown the temperature and clock speed of CPU. Opened GCAM and took some photos the temperature rose from 40-65 degrees in an instant and it died and I noted all the CPU cores are ran at max clockspeed.
So, I switched back to stock rom, used Armoury crate to limit and limited the CPU clock speed of GCAM, Again same result phone died (like the custom rom Armoury crate displayed the max clock speed of 2.96 Ghz, though the app was being set to use lower clock of 1.92 Ghz)
After using and failing to limit CPU clock using kernels, It was conclusive that the temperature is not causing the issue, "NO_THROTTLING" of CPU does.
During heavy load on CPU like gaming or benchmarking, all CPU cores will run at high clock speed, which increases the temperature of CPU. To counterfeit this, the system applies slightly lower max clock speed to all its cores, makes the CPU to run at slightly lower clock speed. As the temperature increases the max clock speed will get reduced till it can no longer produces heat (auto cooldown) on doing work. Same applies for GPU. This is called throttling.
What will happen, when throttling doesn't happen? All CPU and GPU cores run at max speed which increase the temperature, when there is nothing to stop the rising temperature. The temperature rises further [A10's thermal management kicks in] and shuts the device.
During charging, the CPU temperature will be higher due to battery dissipating the heat, so when there is even slight load on CPU (background activities like downloading) rapid rise in temperature even for few milliseconds kills device.
Maybe none of the testing devices have this problem & none of the developer devices have this problem, but this problem does exist and I'm asking ASUS to release the patch for devices which lacks controlling CPU clock speed via Armoury create, and fix the device which doesn't throttle (thermal engine)

Temporary Solution: Manually down clock the CPU and GPU
After so many failed attempt to apply lower clock to CPU, I found the location where the max clock speed file was located.
[I modified the file and put together in tasker (paid app to automate things) found my CPU finally throttled again]
I shared the values taken from asus thermal management applied those values and uploaded it.
Be careful, This might brick your device if used improperly, if that happens you might need to flash raw image so backup anything important. Don't point me the finger afterwards. If you are okay with that lets proceed.
We Need root access and root browser. If you have root access open any root browser and Extract the attached zip file
It has two folders and some files. CPU Reading folder has all the CPU max clock speed you can use to apply lower clock.
the folder contains 9 digit number like 295241178
First 3 number denotes max clock speed of Prime core i.e., 2.96Ghz
Next 3 numbers denotes max clock speed of Big core i.e., 2.4Ghz
Last 3 number denotes max clock speed of little core i.e., 1.78Ghz
for GPU First 3 number is the MHz of max clock (6750 is 675 MHz)
Select the clock speed you need
(lower number = lower clock speed = low performance = less heating
Higher number = high clock speed = better performance = more heating)
CPU has 9 different clock speed littleBigPrime combos
Gpu has 5 different combos
Applying clock speed
Replace the CPU file cpu_max_freq to the folder /sys/module/msm_performance/parameters
Replace the Gpu file max_gpuclk value to the folder /sys/devices/platform/soc/2c00000.qcom,kgsl-3d0/kgsl/kgsl-3d0
Replace those files and see if your device shuts down on gaming, if it does choose the lower value and repeat the process.
Everything should work properly now. It might not be great solution but it will prevent shutdown.

Im creating an app to solve this, which is in progress. Will update once everything is done.
por favor, preciso deste aplicatirvo!

Are you done making the app, cuz i really need it rn
its power ic related issue. throttling app is reducing the performance
