is the 530mhz ocing for pxa 263 or 270?

Nice but the autoscale function is grayed out on my ipaq 5555. Or is that just a trial version limitation? It isnt mentioned if it is.

It's my understanding that running this to slow down the processor on a 2200 series iPAQ is acutually DETREMENTAL to the battery life due to the way the FSB is managed, it slows down the fsb but the processor speeds up to accomedate the increased workloads. But according to the same logic of wherever I read this, it will improve your battery life on idle right?
Of course if you are speeding up the processor and FSB you should expect the battery life to decrease right?

If anyone else has read the article I'm thinking of would please explain this to me. (or if you understand the implementation of the 2200's FSB and Processor)

Lasher,
I don't know if what you see is a trial limitation or not. It's been so long since I used the demo, this was purchased a long time ago. I am guessing it must be a trial limitation, because Autoscale is a working option on my 5555 with the purchased version.
Best of luck,
buckyg

I've got a 4155 and it's grayed out on mine, too.

I have been using this app for a while - it's great to regularly overclock to 500Mhz and drop down to 100Mhz when I need to conserve battery power. I use the 100Mhz setting when reading ebooks & typing for a while - the CPU usage does not get that high doing these things & I get longer battery life.

regarding my earlier post, I beleive HP said it www.hp.com I don't have the time right now to search for it on any sites.

Well once I actually read the Readme file it says right at the top the autoscale feature doesnt work in the demo :oops:

So I purchased the full version and now it runs great on my 5555 :)

Those of you running this for a while now have you had any problems running at 500 or higher?

Well I did some tests a while back and you are absolutely right.

Less speed does not mean more battery life. The reason is unknown for me but I think that itīs due to the fact that these OC programs has to fight all the time against the OEMs settings prepare to hold the default speed of these devices.

I have not tested this last release of XCPUScalar neither Pocket Hack Mater last release to see if these releases work different now.

"Oops, I did it again!"

I just ran my test again and I can tell you guys for sure that 200 Mhz does not give you more battery life than 400 MHz.

If some of you want to check if am I right here is how to do it.

I created a while back a this little eVB program:

http://www.pc-counselor.com/bin/BattBench.ZIP

It works very simple, when you push the Start Test button it waits until one % of your battery level goes down, then it counts how many seconds take to go down 3 % . That will give you an idea of how much time your battery will last running at current condition. The program does not do anything else, so you will have to disable any Power off feature in the device. I created it because I wanted to have a tools that I could use to measure the battery life but at the same time I did not want to sit a whole day without a PPC. So I created this little program where the time consumed in each test is around 6 to 7 minutes.

Right after I posted my previous post I went and run the test two times. One without the OC program running - 400 MHz - and another running the OC at 200 MHz sticky. And here are the results...

400 MHz - 4.14 hours
200 MHz - 3.68 Hours

In both tests the PPC was in the same conditions - only my program was running.

I noticed this myself with PHM a few months ago when I checked it out.

I just tried it again to try and get some real figures and a somewhat unscientific experiment showed the following in the standby tab in power settings:

(All readings with backlight off, only wisbar running in background, battery at ~90%)

PHM enabled with auto scaling:
"Aprox. hours left" fluctuates from 6 hours to 12 hours

PHM disabled:
"Aprox. hours left" stabilises at 17.5 hours left


The moral of the story? Don't just assume that you'll get better battery life by forcing your system to do what it doesn't want to do.

The funny thing is that if you increase the CPU load up to 40 % or more you will get the same results - battery life - for 400 and 200 MHz.
