Overclocking XDAIIi

how do I overclock the XDA IIi , I heard there is software Pocket Hack Master 2005. Is it safe to overclock the XDA IIi?

If you try it the turbo mode in the speed settings in the control panel will be unavailable. It'll be the same as standard mode. Also the max clockspeed of the gfx chip/part wil be aft 54 Mhz instead of 108 Mhz which was set by the turbo mode. The latest version does work stable but that's about it. No real speed advantage to be gained because of the above. Perhaps some battery saving but since most of the power goes to the display I don't really see the use of getting a few extra hours of standby time from this while games slow down because of CPU usage polling. For the Alpine IMHO this is just something that is overhyped and not worth the hassle it brings.

I am using xcpuscalar_v2.88 to overclock my i-mate PDA2,the max speed i was able to use is 624 MH and it is very stable and all games and apps are running ok.
You may need to shut it off b4 you use the camera.
Otherwise it is very stable and fast,also saves power as it scales down the cpu to whatever speed your want.

xcpuscalar_v2.88
Thank you

me too, working fine with 624Mhz......unlike previous v2.87 crash with my XDA IIi !

I think this is an excellent point.
I use my XDAIIi extensively for business use and was close to junking it - due to all the crashes and freezes I was suffering.
Then... I turned OFF Turbo Mode. I still use it extensively... only it doesn't crash anymore! The only problem I'm getting from time to time is needing to restart the phone via Flight Mode to be able to get a GPRS connection after using ActiveSync.
I own a licence for XCPUScalar, but haven't bothered to reinstall it or try the new version yet. I can't honestly say I've noticed any difference between Standard and Turbo Modes.
Go figure!

last stable frequency is 617 mhz .
Run mode is 247 x 2.5
Bus is 247
Lcd is 61
Memory is 123
Anyone more ?

Yeah...guess I shouldn't listen to things I read. Now my pocket PC has hard resetted.

I use v3.03 and my IIi works well upto 624Mhz. No crashes etc.... However as has been said already, the camera does not work properly with it, but if you downclock the CPU to 108Mhz then it's fine. I rarely use the camera anyway (i have a proper camera instead!!) so it's never a problem.

XCPU scaler 3.03 make my IIi hang, nothing more than that.

It shouldn't be hanging. It's more stable than previous versions i've used. Works great for me. I'd try uninstalling it, then removing any leftover files manually, then reinstall.

What's the fastest your Wizard has done?

Hi guys,
With the many available overclocking tools available, I noticed that quite a lot of people like to leave their phones on 240mgh, why is this so?
Ive done 264mgh using Omapclock and its been very stable.
Im currently using Batterystatus for overclocking, and Ive done 319mgh... way cool! The camera has no more lag time! However, 319mgh proved to be a bit unstable and I almost thought I got a bricked phone after...
anyway, Ive set my Batterystatus at 260 mgh and its been quite stable.
How about you guys, what top speed have you tried, and which one seems to be "stable" enough for daily use, and what overclocker did/do you use for this? Thanks

I regularly use my Wizard at 273MHz and it's completely stable.

Mine is overclocked at 299mhz now with batterystatus. Fast as hell. I tried one step up but it locked on boot up and had to do a hard boot.

Mine is set at 260, stable - no issues

Wow! 299 sounds impressive. How long have you been at it? Are you on WM6.1?

for those overclocking to close to 300mhz with Battery Status: What is your temperature like?
I leave mine at 195 with cpu scaler to keep my battery lasting a little while longer.

273 is 95% stable for me.

By Previous Wizard is only stable at 247MHz, any value higher than that will cause automatic reboot when a call is arrived.

is the energy consuption much higher when overclocking?
cauze i'm not sure if i dare to loose too much precious standby/tel time.

what are the possible ill effects of overclocking your wizard to say 221mhz? I know battery drain is likely, but how much and what else could go wrong?

It doesn't seem to change the temperature too much. But it probably raises it on average a 1 degree or 2. WiFi on the other hand increases the temperature dramatically especially if i hold it in my hand for more then 15 minutes.

It's WM6. It's been at 299 for about 1.5 months now. I set batterystatus to bring it back to 195 when in suspend(off) mode and back up to 299 when it's awake. As far as battery drain I'm not too sure. Batterystatus saw a peak of 3000mw with everthing on. Not sure how accurate that is.

Great Topic!
I used to use omap and batterystatus as well and keep my device at 264 and it was very stable but the roms I were using were such battery hogs...now I'm using 11.0.1.1 wwe and it's the most stable rom I've used so far....battery life is very good and so I've held off overclocking because so far it's really not slow and I dont know if overclocking will effect battery life....I'm now curious based on this thread and will run a week long test using batterystatus and post my results on friday with what ever settings I used and check to see if others have done the same so we can learn where we can comfortably overclock our devices.....

I've ran at 299mhz using BatteryStatus for at least 6 months now. Seems very stable at this speed. Although I do have the occasional soft resets which are most likely from software glitches, memory leaks and WM6.1 incompatibilities. I can also underclock as low as 95mhz and seems stable. No one has ever mentioned to me about not getting their SMS or phone calls.
The temp is reasonable at 77deg F just out of idle and around 88deg F when I'm playing a game. My battery usage seems pretty reasonable. I've always overclocked so don't have anything to compare it to. I can play games for 2-3 hours, make a couple minutes worth of phone calls throughout the day, about 20 SMSs, a quick session or two of Wifi to check emails...and still have about 30-40% remaining.

You know, I clock at 252 with omap, but when I installed batterystatus, it read at 270, even though omap still said 252. I'm confused... which is correct? and why the difference? I've since uninstalled b-status

I run my q9100 at 260mhz without any problems. I have WM6.1.

You don't have to worry about killing the battery during standby because batterystatus goes back to normal when in standby mode.

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.
4n60 said:

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.

[Q] 1% Batteryconsumption per two minutes normal?

Hey guys,
I just wondered if you guys have the same problem that you lose 1% battery every 2 minutes when you´re having your display on. I know it´s quite known that big screens suck the battery like a vampire but that´s just odd, because I don´t even have to do anything with the phone just staring at the activated display.
I´ve had these troubles from the beginning with FW 10G then updatet to 10H and did factory reset- nothing changed. I tried different brightness levels without any differences in battery consumption, which is totally uncommon. And the freaky thing is there is no difference whether I have airplanemod on, wifi turned off and so on. It is always the same... Although when the display is off there is as good as no consumption but really 1% battery per 2 minutes that´s just sick. I can´t believe it.
Now i wondered if this is normal or if I should turn it to the customers service to check it.
Please tell me if you explored the same things with your LG 4X HD

Well i found it odd too but if you would root the phone and install something like setcpu you would actually see
Min CPU Freq --------------- 1.5 GHz
Max CPU Freq -------------- 1.5 Ghz
Er yeah .... after saying that i think you know why its using the battery so fast. I rooted my brothers phone and changed the clockspeeds , but no matter how low i set the min freq on "no frills cpu control" it always shows on the toast message 750 Mhz or somewhere around that.

Well thank you... I´ve rooted it and thought it had something to do with apps running in the background but it didn´t help at all so I thought this can´t be, mine must be wrong somehow.
Especially because i haven´t heard anything in reviews or forums about this rapid battery drain. This is something I´m wondering most, how can a phone taking so much battery be rated so high It sucked 3% watching a 3 minute video on youtube...
I won´t think I´m going to be happy with this phone and the best is when I contacted customers service later today they told me to send it in because its not normal, but now that you said the cpu is set this high no matter what, I can just suggest they don´t know anything about their phones...
Bet the only reward I get sending it in is "all is fine our phone likes to suck your battery, so what? Just keep the display off"

Screen off "deep sleep" battery drain is quite bad too ..

For me. The battery says its fully charged after 1hr. But it actually takes 3-4hrs befire it reaches the absolute full capacity.
Battery lasts twice as long then...
