looking for CPU software to slow the CPU down, SAVE BATTERY!

Has any one got a link for a freeware program to do throtterling of the CPU as in not always running at 400Mhz? I've seen a few more complex ones that you have to pay for but they do all sorts of things? I am thinking of giving it a go and the whole point of Intel developing the XScale chip is because it's able to Scale down the speed (Hense the name) this saves a lot of battery life apparently...
Any ideas?

Downclock your processor will not take a lot saving your battery life (about 10%).
Use XCPUScalar for your Xscale cpu,it let you choose 100-200-300-400-472 Mhz mode.

Double post

thanks for the reply unapproachable2kx I will take a look into that program... Great work...
Hear is a direct link for any one that would like to look it up as well
http://www.immiersoft.com/
does the program expire at all? has any one done any testing of just very basic PDA work as in address lookup, phone number lookup and that sorta stuff and seen how much extra battery like they can get out of there PDA?
Is there any programs that can automaticly scale the speed of the CPU acording to CPU load that is freeware? Will Microsoft be implamenting CPU scaling in the Second Edition of there 2003 OS? still can't belive that its not a built in feature if the CPU's where designed to scale acordingly...

Does no one else know of any others that can scale the CPU speed according to usage? ass well as the software being freeware?

The Xscaler prog is not free.

Thanks for the link xda-rocks, Have you had any trouble using this software on the XDA II, I see they give you a bit of babble about you may have to do hard resets and stuff like that.... Have you had any problems as yet... I have never used any CPU throterling software and am just wanting to play around with it a bit..
Do you notice a extended battery life if you use this software at all?

No probs so far, but haven't really had time to try it - only just installed myself.

At wich speed is your Wizard running (POLL)

Hi!
I was wondering on which speeds people have their Wizards running? I know there are a lot of people using OMAPclock so if you could enter your values into the poll it would be much appreciated. Also with this programm BAtti http://pda.jasnapaka.com/batti/ you can check the temperature of your battery! Wich temp. is acceptabel (is there any relation to the tmp of your processor?
My Wizard is running @ 264 Mhz and in rest, battery tmp. is 28.0c

195mhz

264 solid as a rock

technically....
the poll didn't let me pop my answer in (i run at 228 or 240, both of which are excluded).

i just overclocked to 240 using OMAPclock..
anyway to make sure it really is at 240 though? The system information app in WM5 still says it's 195.. although i think that's just a label.. not a actual clock measure..

You can use TCPMP with a given file to benchmark - just benchmark before and after overclocking

i like to run it on 240mhz but whats with the batt life?

I run at 228,
mine resets sometimes at 240

I got my MDA Vario just for a few weeks...it is a whole lot faster then my previous SonyEricsson P900, so for now I just run at at default speed

Before ROM update = 240mhz consistantly
After ROM update = standard 180mhz.

I run at 216, but it resets it's self at random times.

I've been running my Qtek 9100 at 204 MHz since Sunday with no ill effects. Battery life seems not to have been affected significantly. Still running the original ROM -- I might try an upgrade in a week or two after I've become more familiar with the unit.

264 24/7. no resets

overclocked to 240 with out rest or any problems

Because I use push-mail (so GPRS is on, all the time), and BT is also turned on 24/7, the battery drain is significant. I noticed a major increase in power consumption when I overclocked the CPU. Normally this CPU is smart enough to clock-down when not being used. When using the overclock program, this intelligence is switched off (or doesn't function anymore), resulting (in my specific situation), in a battery life of about 12 hours. When I run the CPU at default speed, it easily manages to live for 24-36 hours without craving for an outlet socket

264mhz on omap but it tells me 250mhz on tcpmpm.
(i'm posting this using my wizard, why is it putting two spaces?)

With the latest ROM I find the standard speed is adequately fast now, so I run mine at standard speed but increase to 240 when using skype to get rid of the choppy sound, reverting to standard when I close skype.
( I use a modified shortcut for Skype which automatically launches OmapClock and increases the speed when I start Skype and reverts to standard speed when I close skype).

How do did you create such a shortcut? I would like to overclock only when using TomTom.

I have got my Vario on 240 Mhz now. I have flashed it with the new Qtek rom (release 24 march 2006).
But even after installing memmaid, I can't keep it at 240 Mhz after waking up. It will be set back to 180 Mhz
I did make a new Event in Memmaid after waking up, but that doesn't work.
Or could it be because I did not register Memmaid yet?

1-2tje -
Extract the attached file to a new directory on your device called 'omap'.
In File explorer you should see the omapclock.lnk with a tomtom icon, and when you launch it it should start tomtom.
If not, then open the omapclock.lnk in 'Notes' and alter the location and/or name of the tomtom executeable.
To check the speeds, launch omapclock.exe before launching the shortcut and see what the speed is. Close omapclock.exe then launch the shortcut. While tomtom is running open omapclock.exe again and check the speed. Close tomtom and after 10 seconds check the speed again - it should be back to normal.

BatteryMeter or OMAPClock

Hi Guys,
Pretty impressed with this site, the dedication and commitment everyone here has.
Just thought to pick minds....
Which is better of the 2 clocking apps : OMAP (of which I could only find ver 0.2) or BatteryMeter , gives the best overall performance vis installation file size and continous use ?
Your thoughts please
AD10

I think they are the same thing, BatteryMeter provides the nice user friendlier interface that invoke OMAP (or you mean OmapClock?). For small size, OMAP is a command line simple tweak etc, but maybe difficult to set up, esp if you want it to be still around after suspending your phone. So, probably for start, try the Bmeter.

Don't you mean BatteryStatus instead of BatteryMeter?
Anyway, BatteryStatus, despite the name, has also overclocking features and has the advantage that the settings remains if you perform a reset. As far as I know, Omapclock does not.

Thanks guys,
Yes I meant BatteryStatus and OMAPClock.
I have tried both, and stuck to BatteryStatus - offers more information and seems to be constantly supported by Kai.

OmapClock and batteryStatus read different clocks
I used OMAPCLOCK to set the clock to 208 MHZ, however batterystaus, even not using its overclock function reads it as 221 MHZ instead.
Which one to trust???
Tks

I used OMAP for a while, but I was able to overclock max 246, now I use batterystatus and I OC to 286 without any problem. (Also BS has many more features over OMAP)

Built in cpu scaling

Hi all,
Does anyone know if there is a registry key to disable the built in device cpu scaling?
The reason I want to know is that I have been playing with Pocket Hack Master and noticed that there is an option under settings called "disable device built-in scaling".
I have discovered that this option has fixed my issue with incoming calls being really sluggish and my ringtones being really jittery. It seems that when a call comes in my device is running at around 100MHz and then has to struggle to ramp up the cpu frequency in order to handle the sudden demand for rendering the display, playing ringtones, etc etc. If I tick the "disable device built-in scaling" option the device always runs at full speed and when a call comes in everything works fast like it should with no ringtone jitter.
The thing is I don't really want to run PHM all the time as it is a bit heavy weight, so I was wondering if there was a registry setting to change this without running PHM?
I would much rather run Xcpuscalar as it is more lightweight, but I'm not sure if this simply overrides the built-in scaling or not. Can someone confirm this please?
Cheers,
Richard.

Unless I'm mistaken, the XScale technology is there in the hardware but needs software, like PHM or XCPUScalar, to enable it. So if you don't want CPU scaling just delete the software!
For what it's worth I use XCPUScalar to overclock my Universal but I have a slow clockspeed (208MHz) when the device is under low load. That seems to work well.
If you want a visible increase in performance without tinkering with the CPU, try searching here for the registry hacks that increase cache sizes, or install something like Tweaks2k2 to do it for you.

When I installed PHM the software told me that my cpu was running at around 100MHz before I did any kind of tests or under/over clocking. So I think WM5 must have a kind of PowerNow capability built into the software for the cpu scaling. PHM has that option simply to turn off the built in WM5 scaling and replace it with its own better (supposedly) scaling.
This would explain why my older XDA II running WM2003SE had no problems with ringtone playback until I upgraded to WM5. I think that WM5 has the cpu scaling built in.

I think the CPU scaling is built-in the hardware and not software. PHM can somehow disable it and it actually fixed my pda from hanging up when being turned on.

Problem is, PHM is a bit of a heavy weight application to have constantly running all the time just so that I can turn off hardware cpu scaling. Its a shame there is not some way of turning it off with a registry setting or small light weight application or service.

Uni speed and ROMs

We use the Universal for speech systems for people with disabilities. However the speed of the device is marginal for us, because the system itself uses a massive (30%+) fraction of the processor time even when the system is at idle.
I've just been asked if using any alternate ROM images might help speed the device up much, and I haven't got a clue. Help!
Does anyone know if any of the ROM images that are out there makes a significant difference to the speed of the universal? Is there a ROM image around which completely removes all phone functionality (not all our users use the phone)?
I'd be very grateful for any guidance, before we start trying ROM images at random...
Stuart

Hello, first of all, -and I'm not sure about this- I think that the ROMs images are not available at this site's FTP anymore.
Then, if you can have a ROM, prefer the "plain vanilla" ones, unless you might need several extra programs, if you need speed, you need a light and simple ROM, there are several of them, from Helmi's, to Ivan's and others that I just can't remember now, look out in the posts and find a stable one to use, test it with your app until you think is the right one.
Alternatively you can increase your CPU's clock, but this drains the battery faster, a solution for this might be to install a larger battery, your use of the uni might permit all of these things.
I haven't tested any custom ROMs, but I have a friend with a uni that has installed in its uni a Helmi's ROM, I saw it, it seems quite speedier than my T-mobile one, he told me that the voice tags call fuction didn't work and something else, but, was it faster indeed.
bye

have you tried to kill useless proggy at startup???
if you want i may be able to make a clean rom for you...
actually try increasing the pagingpool a simple hexedit on existing roms (wm6 section of this forum look for helmi's kitchen)

Thanks for the suggestions so far.

I've tried killing everything I can. The processor is occupied by one thread within devices.exe; and I can't really kill that process... Everything else had minimal/no impact.

What application are you using to identify process usage? 30% sounds very high to me.

The remote tools in Visual Studio. Shows 1%-4% processor usage at idle for other PDAs, 30-35% for TyTN and Universal (the only 2 HTC machines I had access to). I used the kernel tracker thing to track execution, and it was one particular thread in devices.exe which was both busy, and also, sometimes, thrashing around at <100 micro-s frequency.
This figure does fit with our other experiences. The particular speed problem we have is with a library which is spec-ed to work on any machine with 400Mhz+ processor. Works fine on other machines, including some quite old PDAs, but has 'issues' due to slow processor on the Universal and is simply unusable on the TyTN.
I couldn't find anything I could do to improve this in RAM - and a colleague asked if any of the alternate ROMs might help - and I've haven't got a clue, but hoped someone might know if any of the ROMs are visibly faster.
Stuart

Have you tried changing the default clock speed?
Hi Stuart,
I think there are a lot of applications out there which allow you to overclock and change the clock speed of Xscale CPU's. Things like XCPUScalar 2007. If you look at this thread(http://forum.xda-developers.com/showthread.php?t=304786)you should be able to find some useful information regarding scaling the CPU speed, hope this helps.
Will.
