Lowering down frequency of CPU - if unused.

Hello,
I saw somewhere on some PocketPC application that was lowering down frequency of CPU if device was unused - because of saving battery.
(sorry for my poor english)
I'd like to ask you if:
- is it possible and working (saving energy)?
- isn't it unhealthy for CPU?
Maybe I am just wrong but it sounds cool to me.
Thanks for answer!

iv heard of that before, i think its called *speed stepping* dont quote me on tht.and intel use it on there cpu's but i dont knw if a phne would support such a thing.it does and would save enerrgy by reducing the clock speed of the cpu it can use less volts at the core etc
now that you have said that...i wonder if you could over clock the cpu on a ppc???
would void warranty and the usual but would be good for certain handsets.
sorry i havent actualy answered ur question though

There is no way to Overclock the Kaiser so there will be no way to Underclock the Kaiser from what i have read.

Yes for some PocketPCs, but it's depending on the CPU, and there's currently no solution for the Kaiser.

Nope. I've over/underclocked most of my previous PDAs.
However I was more often overclocking than underclocking, as those devices are already slow enough. Unless you use it like an MP3 player for hours without doing anything else, with screen off, and where you know you need long battery life, it's just not worth having to put up with a device that is slow as hell for minor savings. There's not only the CPU drawing power there - even slowing it down by 2 won't save you much more than 10-20% power when in normal use with screen on... the backlight will already draw more than the CPU at normal speed.
Actually you might end up using more energy with the device underclocked, as you'll be staring at that lit up screen for longer while it *tries* to do what you asked it to
When "unused" as you mentioned in the title - which I understand would be when it is in your pocket doing nothing - the CPU is already in sleep mode and not running, so no such savings possible here.

Thanks for replying...
I was overlocking too some of my ppcs but it wasn't useful everytimes... (freezing etc...)
I was worried about underclocking - I don't have any experience with this...
Ok, now I got it.
Well - cool and fast PDA = daily charging...
Thanks again...
BTW: I can't turn off backlight in my kaiser. It isn't possible ?

No unfortunatly it's not possible. This is my first PDA which does not allow to turn off the backlight. You can just put it as low as possible.

You may not be able to shut off the backlight, but with S2U2, you can set it to lock when you shut off the screen, thus allowing you more power saving.
But as for idling saving you power, if you have TCPMP player, you'll notice that it can read the processor speed somewhere below 400MHz. The processor's designed to automaticly adjust to save power. I once saw mine running at 195MHz.
It may not be possible to manually control, but it does do it automaticly. And underclocking actually increases the life span of the CPU.

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?

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.

ASRock N68-S overclocking

Hi
On sunday i bought a asrock n68-s motherboard and a AMD Phenom II X3 720 Black edition processor and i cant figure out how to overclock in the bios.
I have tryed increasing the multiplyer from x14 to x16 but then i restart and it doesnt boot.
The spec of the pc follows:
phenom II x3 720 2.8ghz
asrock n68-s mb with untied overclocking technology
2gb of samsung pc 6400 ddr2 ram
500w psu
can u help?
thanks

Instead of raising you multiplier, try to lower it 1 or 2 steps, followed by lowering your HTT multiplier, then set FSB:Mem freq = 1:1, then raise up the FSB by 10% of increasing number, if you can't boot try to raise up core voltage & northbridge voltage (becareful!!)..
First, you must know at how high your memory can run (both at tight timing & lose timing).. AMD platform usualy prefer tight timing to get better speed (at games of course..). It's your chioce, use tight timing at lower FSB, or use lose timing at high FSB..
P.S.
Some Phenom X3 can be unlocked to activate the other one core, so it will be recognized as Phenom X4 (not all X3 processor can be unlocked)..

Try to make some faults. Hehe. Go to Bios and set there. It will be probably there.

Other Problems!
Since i bought the pc bit it keep shuting down randomly on its own. And i dont know why
Can you help?

Check temperature of processor, chipset, & memory (at idle & full load)... If everything is OK, make sure you have a good PSU, sometimes voltage dropping over 5% can lead to system failure..
Also check shutdown temperature (overheat warning) at BIOS, make sure it's not set too low..

Yeah ive checked the temps and stuff and there is no reason why it shouldnt shut down. Apart from POWER!!! But i have tryed 2 psu's and no luck

Mine was doing the same.
I know you've tried 2 psu's but you didn't mention their power rating.
Also, often, cheap psu's lie.
I put an 800w one in, invested £30... it's running fine now.

about the OC'ing - leave the multiplier alone (can you even modify those on amd cpus?, cause on intel theyre locked) increase the fsb if that doesnt work try lovering the memory speed and then increasing fsb(works for me)! (for me the OC goes like this - open bios > cpu level up > set to "crazy" :d now its 3.1GHZ from 2.4 - used to be 3.4 until I started to mess around with it! the max I can get (while ocing manually) is 3.8Ghz stable enough to boot and play crysis!!! BTW its a intel Core 2 Duo 6600 cpu!!
oh and you should think of getting a cpu cooler(with stock cooler I had about 70C when OCd now I have 39C), or maybe a gaming motherboard(yes theyre more expensive, but you'll have easier life with utilities which will OC it for you in bios)!!
Do you think its the your PSU fault (about shutdowns) cause im using: C2D 6600 , Asus Striker II Formula, 4 kingston ram modules (4gb in total), NV GF 8800GTS 640mb, a HDD, optical drive, 2fans, and cpu cooler with fan!!! -- al of that is running on a 480W psu without any shutdowns and problems like that!

Ye the motherboard i got is an special ocing board
And is there any other names for fsb cause its not listed in the CPU Configeration. I up'd the multiplyer to 3.0ghz (about x15?) and it wont boot.
Takes about 7 times switching on and off to get working again.
Can i put my memory up to 1066?
My cpu is stock 2.8ghz, which is what it is now.

I sorted out the shutdown thing it was windows 7 beta had run out and was shuting down every 2 hours. But i went out and bought windows 7 last week.

I have dual boot system with WIN7 Ultimate and WinXp pro - didnt buy neither of them!!
Check this out http://www.overclock.net/amd-cpus/475649-amd-phenom-ii-x3-700-series.html look at those OC's if you can get all that stuf (fsb ...) in the same speeds then you can go pretty high with your cpu -- but dont overheat it - I reccomend a good CPU cooler like Zalman CNPS 9700 Led (I have one )!!! vut sometimes you cant get as high because of the mobo!!!

Overclock VIVA occasionally. Can we ?

Subject says it all, 200MHZ sometimes doesn't cut in, if we need the speed, what is the best app out there ?
Thanks in advance

Found the solution...
Thanks for looking at the thread ... It was shinny isn't it.

Alright, let me save your time. Just search for Omapclockkeep, you'll clear your old taboo.

Just for the information, i have happily cruised my VIVA's CPU at 250MHZ, battery life is ok, not much affected.
Battery lasts 2 days with occasional WIFI plus Bluetooth.

I am using Omap keep cause you can keep the default speed at ideal and as soon as you start using it, you can set the speed like 250 and gain the extra performance through overclocking...

I'm using Homescreen++, which has a great overclock utility called CPU Scaler. It dynamically overclocks the CPU when the phone actually requires it, therefore saving lots of battery life. It also reduces the speed when it's idle to save even more. You just give it a min, max and boost value(when apps are really demanding) and it does the rest. It also monitors power consumption(maH, mW) and CPU temp. Good stuff.

It's actually called NueOverclockTest, but you are right, it's terribly unstable and will freeze your phone 95% of the time. When it works, however, it's very nice.
No2Chem, the only developer who seems to know how to overclock the Xperia processor, dropped off the face of the earth in September 2009. My theory is that Qualcomm kidnapped him and is forcing him to use an underclocked Palm M505 as torture.

Xperia X1 "overclock"
Ive been investigating the same situation because i would love it if my X1 ran faster to keep up with more modern smartphones out on the mark these days. So heres what ive found out thus far;
- With stock settings, the Xperia X1 cpu (im using MSM7201A 528mhz cpu) is actually underclocked to 384mhz when the battery is being used, and then further underclocked to ~225mhz when the phone idle's for 5000ms.
- However when you apply external power to the phone, the cpu core runs at its full 528mhz speed. I found these power saving techinques employed by HTC or SE or QUALCOMM to be useless, because ive been running my phone at full speed, highest voltage, and the battery life difference is un-noticable.
- Here what you should do to at least make sure your X1 is running at 528mhz (which made WM actually significantly faster) to give yourself a psuedo-overclock;
1. Download "nueDynamicClock-122-v1.3-pack.zip" which i have attached to this post. Extract, copy the contents over to your X1 and run the SETUP file from your PHONE
1b. If you get a security error, you have to install the "EnableRapi.cab" file which i have also attached
2. Once installed, the cpu frequency settings can found it you click on Starty >> Settings >> System. There is a new "processor" icon, and all the settings can be found in there.
The program is very flexible on how you and when you want your processor to run so experiment to find your best needs. I keep my processor set at a constant 528MHZ @ 1.325V and i get the best performance out of that.
Anyways hopes this helps, give some feedback if possible. CHEERS :

I have just try it and it's look to be really faster on battery !!!
I will see for power consumption and stability in some days but the first thing is impressive !
Thanks

have you noticed anything with battery consumption yet? the only changes ive noticed are the obvious, such as running/watching near 720p quality videos on battery power and multitasking the **** out of the phone. overall general performance has definately increased from my experience, and i am glad i found this tool. Couple it with the right rom and you now have one of the fastest windows mobile phones (besides HD2) on the market. YAYAYAY! xperia x1 is still useful!!!

Yes I can confirm now that the battery consumption is not different than before !!! and for the moment, no bug at all!
And the speed of the phone is definitivly better !!!
Very great !
I'm surprise to don't see more reply on this topic, this soft is a must to have !!!! My Xperia will have some nice day more

I'm gonna install it and try it as soon as I wake up tomorrow

I will try this one and see the difference.. thank you for the tip..

Thank you for your tips!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I'm quite skeptical. I'm pretty sure that the X1 is NOT underclocked when on battery power. If someone shows me before/ after benchmarks, I'll be a believer, but I think this is the placebo effect.

If overclocking works, it will also speed up the boot time, won't it?
I've tried independently on counting startup time. But I don't see different between Max Performance and Default.
Anyway, is it safe if I try it on X2?

Click to expand...
Click to collapse
there is an option in the app which is for starting the app after the boot sequence...that should be the reason why there is no difference in boot time

to all you haters
ok first of all;
1. everyone HAS TO REMEMBER that i first ran this application on a STOCK R3A ROGERS CANADA ROM. what i reported is what i noticed, and the difference between the OS running at 384mhz and 528mhz on battery certainly isnt a "placebo" effect. You might be using a different rom, where the cook changed the cpu frequency settings himself but i certainly dont know. If you dont believe me that is underclocking issue is actually an issue, i suggest you google search the topic and check out how many hits you get.
2. The Xperia X2 is running the exact same MSM7201A 528 mhz cpu soo X2 owners should definately check to see if their cpu's are underclocked.
3. Finally i was just trying to help, i love my X1 and i want people to love their X1's too.
ENJOY EVERYONE lets keep this phone ALIVE

installing it right now...

Its amazing.
