Overclocking App available in the market!

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?

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.

HOT battery~!

OK...so MUCH THANKS to Mr. Carlisle for gettin me all squared away with rooting my Hero and upgrading to Froyo 2.2. All back ups complete, apps downloaded and only major bug thus far is the camera...SO....why is my battery running at 105 degrees on average? What should the normal range be? I turn it on @ 6 am after charging to 100% and wiping battery stats and ten hours later recharge it to 100% (Currently @ 50%) and all day the temp has been between 103 and 105. whycome? HELP!

Because on FRF91 on Cyanogen mod (which i assume you are using) is overclocked to 710 mhz, where the hero's processor runs at 528 normally. My suggestion is to download an app called overclock widget from the market, (Obviously, it's a widget and you'll have to add it to your homescreen) and set the minimum and maximum clock (processor) speed to 240mhz(min) and 518mhz [or 534, if you want to, but it won't make much difference] (max).
You can set the max (or minimum) clock speed to be more or less. Lower clock(processor) speed=More lag but better battery life, and potential to freeze your hero because the processor can't operate the system fast enough. Higher clock(processor) speed= Faster and less lag but less battery life and can damage your touch screen (It's happened to me). if you leave it at too high a clock speed for too long, and can also freeze your phone because your processor can't operate at that speed and crashes your phone.
It's up to you if you want to overclock or not, but you should keep it resonable, and if you have heavy phone usage, don't go much further than 613 mhz for your max. There is also another program called set cpu that is avalible for free for xda members, but is a paid app on the market. Using that, you can set your frequencies to the default hero processor, or of other phones. But overclocking over 710mhz could do some harm to your phone, so be careful.
If you say, "I wonder if this will damage my phone," then don't take the chance without asking around first.

If you have any more questions about overclock, pm me, and I can help you out.

That temperature range, ~40C is completely normal when charging and using at the same time (with me, anyway). I'm OC'ed to 710 and using undervolt, too. The highest I've ever seen mine go is 43C, or about 109F. I don't really know where the "danger zone" is, but if I had to guess it would be around 48C or higher.
Edit: I reread your post, and do you mean it's at 40C always, even when it's sitting doing nothing? If that's the case then follow Ryoma Echizen's advice and fine-tune your CPU speed.

[Q] dynamic overclocking

.
..

I use setcpu to do this.
Look into the governors, choose one.
Then choose the appropriate thresholds (in the advanced menu) for what you do.
It doesn't allow you to tweak per app, but tells the cpu governor at what %of cpu to move to the next cpu speed (up or down).
I set mine very low, as i care more about battery than performance. So my up threshold is like 95% or something.
But my down threshold is a lot more agressive.
But you do the opposite.

Hello,
my question is regarding dynamic overclocking. I've used the ones that raise the speed when under a load - but my question is -
Is there a way to return to stock clocks after certain time?
Explanation:
situation1: I want to check new single mail or open new single IM or check university's website for some news, I want the device to be FAST as possible, nevermind the battery.
situation2: I want to use maps/navigation/IM/games/web browsing for longer period of time (hours?) with the screen on. I don't need all the power when I play solitaire, text on IM or browse not-so-important news websites.
I think when I've seen the realtime clock displayed on my phone it jumped to max clock right after I've clicked almost anything on the screen. I want the speed-up, but after certain period of time to stop doing this in favor of the battery life-time.
Any ideas how to do this? Thanks!

Yes, just throttle the cpu to give you more power when you are sluggish. That could work for you.
Me? I have my droid do 110 when screen is off (works quite well!), and then I FORCE the unit to 1000 when plugged in. Besides that i throttle the cpu based on battery power: more cpu power with more battery life. Makes my droid last longer.
I might want to add a throttle up when sluggish and not in my personal battery red zone and a throttle down when the cpu gets too hot period.
Any cpu frequencies that you all would suggest?

Thanks for the reply, but - think about this, I will start a 3D game, it will use 100% of the cpu so it would always stay at the highest possible frequency (+highest voltage). I don't want that.

I dont get it?
You dont want max speed in game? Why do you overclock?
If the game requires 100%, the it will (and should) clock up.
As soon as the game doesnt, it will clock down (depends on your threshold).
The only other i could see, is to change the max clock rate in setcpu before you play the game. This will ensure it doesnt clock higher than your choice, but requires a manual step.
But seriously, if your cpu is pegged at 100, why would you not want it to step up the higher speed?

MuF123 said:
exactly - I don't want minimum battery in game, that's why I don't want to overclock.
actually from the nature of 3d rendering I think every game will run at 100%, but the situation when the game hits the frame limiter (not likely on milestone).
I want snappy performance while doing few quick tasks:
e.g.: new IM comes, I want to unlock, load the application, get to the IM, reply, lock. (40seconds)
or
taking phone from cradle - I want the phone to load homescreen fast, rotate the screen, open phone app, to look at last missed call and call back (20seconds).
Battery life won't be affected by 40 or 20seconds of ~1100mhz, okay.
And then I start a game for a prolonged time. It will run smoothly even on 550MHz, the additional frames I see are just waste of battery = I don't want that.
So now I have two options - either run at max speed and it will be always fast and it will drain my battery when I decide to play for an hour.
OR
I can use default speeds for longer battery life for everything and I will wait an hour to rotate the screen in browser or IM app.

You could compromise and find a max speed that you could undervolt to make it drain battery like stock. My 800mhz vsel is less than the default vsel @550. So the battery drain is less...
It requires some trial and error, but most "slight" overclocks (700,800; depends on the phone) can be configured to drain less than stock.
Of course, if you feel you need 1000 or 1100, this wont work as it requires increasing the vsel (or at least not decreasing it).

[Q] CPU speed and phone temperature

My specific issue involves SetCPU but I'm wondering about the larger scheme of how things work.
My phone gets hot in the car dock when running GPS, Navigation, and Bluetooth (I don't turn it on but I think my dock does it automatically). The general consensus is to underclock slightly when charging because charging generates heat, and I have a SetCPU profile to do that. Then comes the issue of heat generated from GPS and Bluetooth, and possibly processor load when running apps while docked, so I have two profiles for that: one to underclock a few steps down from the charging CPU speed when the temperature of the phone is at 40* C, another to clock down one more step when the temp hits 42* C, which I feel is at the point the phone gets a little too warm for use.
I've noticed that my phone doesn't necessarily stay cooler and in fact, sometimes it gets hotter than before I started using SetCPU. Over the past few days I've seen temps of near 45* C (113* F), toasty enough that I have to let my phone cool down before I can use it again.
So, my question is if underclocking too much is bad. For example, if I'm underclocking too much, does that strain the processor while it is trying to run apps and hardware? Is it better to let the system handle processor speed? I see this in driving a manual/standard transmission car - if I attack a hill in a high gear, I can eventually reach the top but with increased load on my engine. Maybe the processor speed works opposite - too low and it strains too much?
I used to be concerned about clock speed vs. battery life but now that I'm docking in my car more and noticing the heat, I'm more concerned about the heat. I'm currently using redstar's kernel but get the same results with that or the CM kernel that comes with the nightlies.
If it helps to troubleshoot, or if you want to critique me, here's my profile list.
Normal: 245 min, 998 max (default settings)
Priority 100 - temp > 42*C: 460 max, 245 min
P 90 - temp > 40*C: 499 max, 245 min
P 80 - screen off: 384 max, 245 min
P 70 - charging AC: 576 max, 245 min
(SetCPU related question, sorry if this is too far off forum topic) Are there better profile settings I could be using?
Also, I don't quite understand undervolting in terms of kernels. What effect does that have, if any?

[HOW-TO][MOD]Thermal throttling - screen dimming, cpu speed, charging current, etc.

When I bought Xperia T, after a while, I started to be a little disappointed with performance, autobrightness, discharging when playing, etc.
After some digging deeper into this problem, I have found, that cpu is throttled by temperature. And not only the cpu.
A few minutes of playing game, cpu goes to 800MHz, display brightness goes to level 100 (max. is 255), wall charger current is reduced (even when connected, it is discharging), radio power is reduced, etc.
Change it yourself:
Example:
xo_therm 14 -1000 380 20 NOTIFY CAM_NORMAL cpu_perflevel:1728000 charge_current_limit:0 usb_current_limit:1 modem_level0 lcd_brightnesslevel:240
xo_therm 14 = sensor step
-1000 = -100,0°C
380 = 38,0°C
20 = don't know (maybe some kind of sample rate?)
NOTIFY CAM_NORMAL = obvious (camera)
cpu_perflevel:1728000 = cpu frequency
charge_current_limit:0 = obvious (0 is 1300mA I think, 1 is 1100mA, 2 is 900mA, etc.)
usb_current_limit:1 = obvious (has impact on charging too)
modem_level0 = power of modem
lcd_brightnesslevel:240 = obvious (0 - 255)
Set the highest temperatures, with low enough frequencies and charging current values, to let phone cool down.
"gpu_perflevel" can be used too and there are some other thermal sensors in sysmon.cfg, which are also responsible for thermal throttling.
Disclaimer:
Each device is different and I am not responsible, if your device burns with some values from here.
Both CPU cores always on:
Echo 1 in /sys/devices/system/cpu/cpu1/online and change permissions to 444. And if you want to prevent errors from log (and maybe some unwanted wake locks), rename /system/bin/mpdecision to something else or delete it.

what is temp at what cpu throttles (and other things)?
seems it is lower than other devices, something like 40C, i think my sgs3s was at 76C or similar.. not sure, will check later.
sgs3 was a very hot phone.
Sent from my Xperia T

You can see the temperatures in sysmon.cfg - xo_therm 400 500 = 40 - 50°C for example. Cpu temperature, not battery. There is no tool to monitor cpu temperature, but if you set your own frequencies, you can see with Cool Tool, how long it takes to the lowest frequency.

I have noticed the throttling but it doesn't affect the performance in my case, playing games and watching HD video are fine, just annoying when the screen suddenly does dim.

@OP:
If you don't want throttling, uninstall Androids inbuilt Thermal monitor(No need to tell you the risk by doing that I guess).

Thanks for you valuable advice.

Don't think it would help as that file says 2nd core off values are hardcoded

Still? Damn how long do they take ? -.-
Here is the .apk of the old version. No idea how much works and what doesn't!

Hello,
Could it be some kind of default on your device ? or maybe the application ?
Cause I remember Qualcomm's communicating on their S4 being "cooler" than its opponents when under heavy load.
Can someone else confirm ?
What's strange is that the game you mention (Osmos HD, which I bought some time ago for my TF101) does not even use super high end 3D graphics etc etc ... maybe the perf drop could come much quicker with some cpu/gpu intensive apps.
If confirmed, it might even become a big "no go" on this phone for me.

I've had this phone for a while now and I haven't had a bit of lag while playing any game I have. Everything seems fine except the sudden dimming of the screen when playing games. Don't let this put you off buying the phone, its a great phone
Edit: been playing Osmos HD for at least 25 minutes, I'm experiencing no such lag or performance issue. Only the dimming issue I seem to get.

Well, after some more investigation, I have found, that lags in Osmos HD are not caused by cpu throttling, but wifi disconnecting.
Playing the game is fine, but still, with default settings the temperature is going high and except the screen dimming, cpu goes to 800MHz, (1 core disabled on highest temperature), and phone is discharging even when connected to wall charger.
It seems to me, that the overheating is not caused that much by cpu, but gpu. It would be nice, if it could be tested somehow by lowering the frequency of gpu.

I wonder if the heating issues could be fixed with software patches. Given Sony's desire to incorporate playstation stuff, I find it hard to believe there is some sort of hardware issue.
Wish we could get some more samples to work with.
Sent from my HTC_Flyer_P512_NA using xda app-developers app

Just measured with my settings (in the room - about 23°C):
10 minutes of playing Osmos HD without charging = 62°C CPU temp
With one core running on 1350 MHz and LCD brightness value 150, it's not increasing anymore.
When charging, the temperature will go higher. I will test it too.

Have you tried treppn profiler?
Anandtech says a CPU core draws around 450-750mW while gpu goes 800-1200mW!
Seems like 400mhz is a hard Task for an 225.

If you are still on ics maybe try jellybean? Perhaps project butter may more efficiently handle the gpu.
Maybe even make a list of "stress test" for people to try and see what the various results are.
If all else fails try undervolting the gpu and cpu.

Yes, I tried trpn profiler provided by you, but there are limited options.
It looks like the GPU cannot handle this frequency.
Undervolting won't help anything, but lowering GPU frequency would help I guess. But this cannot be done without custom kernel, allowing this.

I've had this phone for a while now and I haven't had a bit of lag while playing any game I have. Everything seems fine except the sudden dimming of the screen when playing games. Don't let this put you off buying the phone, its a great phone
Edit: been playing Osmos HD for at least 25 minutes, I'm experiencing no such lag or performance issue. Only the dimming issue I seem to get.

Same here. I've been playing Speedball 2 and GTA3 mainly but I have played a few others too and haven't experienced any lag and no performance issues observed at all.
