How do i raise it to 728mhz.......mine won't seem to go higher than 624mhz...not sure what i'm doing

If you fall behind sooner.....you'll have more time to catch up!

please delete my previous post..........i figured it out....sorry

iss it worth the risk to overclock?

Thats what I wanted to know (bump).. I mean there must be a reason for Dell (or Intel) to say this is a 624Mhz device. Ive looked but cant find topics on this subject. Has anyone had overclocking trouble? (heat? crashing?) or does OC'ing to 724 just work with no penalties (other than battery life)?

Also - this program has settings to 'scale the cpu speed as a percent of CPU load' - sounds nice in theory, however the Axim has this function built in. Which function is better?

CPU design leaves plenty of stack to insure accurate transmissions. You can possibly overclock any type of CPU, with a side effect of extra heat generated.

Well yeah thats the base theory, however the extra heat generated might just crash,freeze or even kill the cpu...

Immiersoft says they have chosen and tested fairly safe limits but Id be interested in hearing more details on that

Nope. Its only for bragging rights.

 

Not quite true. While most 'normal' PDA apps will run at 'perfect' speeds on these modern devices, there are a lot of games and emulators (for example the PSX-1 emulator http://www.fpsece.net/index.html) that still need all they can get.

Also, with the dynamic CPU speed scaling theory, one could feasibly argue that the amount of used battery power for completing a specific task remains the same, regardless of what max CPU speed is used.

In the old days, a task would run, and afterwards the CPU would keep running on exactly the same speed. More Mhz, More battery drain. Simple.
Nowadays, the 'Overclocked PDA' would run through the program at 724Mhz and then idle at 100Mhz, while the normal PDA would idle at 100 aswell, just taking longer (but at less battery drain per second) at 624Mhz to finish. Less drain per second, but more seconds -> it evens out.

Personally, if I was positive overclocking would not hurt the PDA I think I would do it, even if I weren't a gamer. Actually.. given the fact that Im in Dell's Completecare 3year plan, I think I'll give it a try..

Keep in mind that "intentional misuse" will void your warranty. And its been confirmed that Dell support people cruise these forums.

Well, I've read the disclaimers and terms of Dell's site, and I haven't seen overclocking mentioned as mis-use.

Still, turning in an X51v with a burnt-out CPU and XCPUScale in flash rom might just look bad, I admit. That is why I am trying to find some assurances first.

Overclocking a PDA won't kill it without notice, I don't think, but it may freeze up if you go too far. Battery life should remain about the same because you are changing the operating frequency, NOT voltage to the CPU as you would with a desktop CPU to really get the most out of your OC. That said, I personally would not overclock a pda due to heat issues. You can't simply slap a bigger heatsink on or watercool a PDA and more heat = more stress to components = decreased product life.

only if you add more voltage to it..

i overclock my desktop's cpu (prescott 2.8, currently at 3.9). i haven't tried ocing my axim yet, mainly because i'm scared of screwing it up. with pc's if you mess up an oc there's always ways to go back, worst case you just take out the cmos battery to clear the bios. with the axim you can't do that (though i guess a hard-reset would do the same...). also, desktop chips have fans/water cooling them, unlike our axims, which i'm guessing use heatsinks.

Well, I have had some experience in overclocking my PDA. I owned a ipaq 5555 and overclocked it for over a year. One day I turned it on and the unit locked up and the screen slowly faded away. It would not turn on and I finally got it turned on by doing a hard reset. I turned on overclocking again and it happened again. The system would not overclock again but worked just fine at the normal frequency. I now own a x51v and have not overclocked it yet. Some units will work just fine but some units may have the same issue as my ipaq. If you do overclock, do a complete backup before trying and I suggest do backups at regular intervals.

What's the actual gain at 728mhz? See a real difference?

I used to o/c my Toshiba e740 and e750 to 472mhz with great success and a very noticeable improvement.

Also, I quickly tried XCPUScalar and I couldnt get above 624mhz either with my x51 - where's that additional setting?
