somas1 Guest Join Date: Oct 2002 Posts: 151	Xscale overclocker There is a guy who just wrote a beta program that underclocks and overclocks the PXA250 200 Mhz Xscale processor that runs the PPC HP 1910.  I think this is the same processor as the NX so maybe he will port it to PalmOs.  The info can be found at:  http://brighthand.com/article/Overclocking_h1910

Do you have a source for this information?  Cliesource and most other sites knowledgeable about handhelds have stated its is a 200 Mhz Xscale

As far as this program is concerned, it doesn't matter, the program won't even load unless you have the right device.

Why did you feel the need to post that reply.  PPC apps won't load on Palm OS devices.  I am pretty sure everyone knows that.

Sorry. I'll clear the posts thru you next time.

I'm sure the program as written won't work on Palm OS but hopefully the same technique could be applied to the Clie. According to the developer Intel is only making two types of Xscale currently:

1) a 300Mhz version that can be slowed to 100, 200 or 300Mhz which is what we have in the NX series

2) a 400Mhz version that can run at 200, 300, or 400Mhz

Supposedly it's just a setting via software that controls the timings.

Are you sure that the developer said that the low end Xscale could only be overclocked to 300Mhz?  My understanding was that the HP 1910 could not sufficiently power its Xscale processor beyond 300 Mhz but that may not be true of the low end Axim and some of the other Xscales on the market. 

 

P.S.  Baloo, I found out that my Playstation 2 games won't work on my nx.

That was the info I was given but I have no way of verifying it. It's possible the Axim may be using the 200-400 chip even on their cheaper model. No idea which is in the NX series. I'd love to see 400mhz but I'd settle for 300mhz

Overclocking usually assumes that the chip is already running at spec. The XScale chips are all capable of running at either 100, 200, 300 and witht he right voltages and the better package, 400 Mhz. All that the people are doing on the PPCs are reprogramming the CPU to run at a faster (or slower) speed, but to still run in spec. The power used is not significant. One test that I saw showed less than half an hour difference in battery life for 50% higher performance (200 to 300 Mhz). What is really cool is the ability to underclock. If you slow the processor down to 100 Mhz while doing things like reading books or other tasks that don't use the processor so heavily, you can increase the battery life. But in no case is anybody doing anything that will harm the processor or affect the stability of the unit. __________________ In Use: Treo 650, 700W, iPAQ 1955, PalmOneTX, iMate Jam, Nokia 770 Old- Asus: A730W, Casio: A11, E-10, E-100, E-105, E-115, E-200, HandSpring: Visor Deluxe, Prism, Platinum, Edge, HP: 360, 548, 650, iPAQ: 3635, 5455, 5555, 1910, 1945, 2215, 2755, 4155, 3115, 3705, 4705, Loox 720, Palm: 1000, 5000, Pro, III, IIIe, IIIx, Vx,m500, m505, Z71, Z72, TT, T2, T3, T5, TC, Sony: S300, N710/760, T615, NR70, NX60, TH-55, Tapwave: Z1, Toshiba: E740, E755, E805.
