With help from the maker of Pocket Hack Master:

L = Multiplier to determine the Memory Frequency
M = Multiplier for Core Frequency (Normal Operation)
N = Multiplier for Turbo Frequency (Turbo Mode)

If you download Pocket Hack Master, the pdf guide that comes with it explains a lot of information.

I thought the program worth it, so I purchased it.

Originally posted by Brewser Folks, I am not sure if anyone has posted this yet, but I finally got tired of the whole AX 2003 problems and went out and bought a HP2215 last night. I really don't think Dell is going to fix this problem and have the speed of the AX to what we would expect. I have a feeling this is the same problem the Toshiba e740 has and that is why Toshiba is not releasing a 2003 update. Both machines are using old architecture. I may be wrong and hope for everyone I am, but I went from one dog (toshiba) to another and I have had it. Anyways here is a CPUID screen shot from the HP2215 for you guys to examine. By the way the the HP2215 is the best PDA I have ever owned the thing is a screamer! I have a database (SprintDB) that took about 20 seconds to load with toshiba, about 40 seconds on the AX (2003 crap), and now it takes about 4 seconds on the 2215. Let me know if there is any more info you need on the 2215.

For the difference in Cash I'm not quite ready to give up on the Axim yet, let's see what the patch/fix from Dell brings. Besides, prices in the Tech Industry usually go down, so either way I'm saving money...

I'm the developer of Clear Speed which is a Pocket PC/XScale accelerator. I'm currently adding support for the Dell Axim series.

My test device is a 300 mhz Axim running 2002 and a PXA255.

A couple observations:
- Dell's control panel applet for processor speed doesn't really seem to do anything. It doesn't affect the benchmarks I use for testing.
- Changing the processor settings so that the PXBus speed is 100mhz (27:2:1.5) doesn't make the device go faster.
- Increasing the memory speed (36:2:1) causes the device to lock even though the processor is still only drawing the standard 1.1v. The memory in these devices must already be running at max speed.
- Running the device at 400 mhz makes things only slightly faster.

My initial reading of the Intel 255 docs vs the 250 docs would indicate that the 255 on the Axim isn't being initialized at the correct higher speed. It's not running any slower than the 250, just the same speed.

The question is whether it makes any material difference in speed.

** These are my observations on my device, your experience may be different. **

There will be a public beta of Clear Speed available for trial today or tomorrow.

FYI: We use an unreleased arcade shooter for some of our benchmarks. It runs at a consistent 30 fps on the Axim 300 and 100+ FPS on a 1910.

That means that the PXA255 Axims (including those running WM2003) are running slower than they need to be. Stock Axims are running like PXA250... I am suprised others are not in this thread posting!

Just ran across this thread now. My Advanced is running a PXbus of 99mhz and it is a PXA255 cpu. It would be nice if Dell set the default to 199!

I had posted about CPUID giving different looking values. The best guess I have is that mayber they are working off of some reference table and wer are dealing with the actual values... I don't know really, but almost all the programs I have seen (including Intel's tables) work with the system that is different from CPUID. Maybe CPUID is just confused? :D


This might help too from http://antontomov.com/cgi-bin/ikonbo...st=20#entry291

"Basically the "autoscale" means switch from run to turbo and back. You know that the L multiplier determines the memory clock and the M multiplier determines the bus frequency. So for the Run mode we have

Run Mode = L * M

for the Turbo mode we additionally multiply this by N

Turbo Mode = L * M * N

As seen, the Turbo and Run modes have the same L and M and different N which means they have equal memory clock and PXBus clock. However, Pocekt Hack Master's Scale feature is much more sophisticated - instead of just switching between Run and Turbo you can assign 4 custom clock settings each with it's own L, M and N multiplier. This means that you can configure heavy loads to run with PXBus = 200MHz for example while keeping the PXBus @ 100MHz for idle state of the CPU. You can even reduce the memory clock (MEMCLK) to 1/2x to conserver the power even more in the Scale settings.

Cheers,
Anton "

You might want to read through at least the last 3 or 4 pages first...

Damoosemander,

I just read the reply I gave you earlier and honestly, it reads differently than I meant it. I was running late for an appointment, throwing stuff in my medical bag, and typing the message....

Sorry about that. I did not mean it to sound like I was being short with you.

:)

I don't remember where I saw it, but I seem to remember reading that the Ax doesn't have a graphics accelerator in it, but most HPs do. That will significantly affect any benchmark using fps, if true.

Astounded EEG

weeeell, someone somwhere mentioned a "MediaQ" GPU of some kind in the axim, although no one has ever confirmed such a thing even exists.

Hi all,

How do I get the info generated by CPUID and dump it in a file for posting on here?
Thanks for any help

It's there - there was a web page posted that had pictures of the innards of an Axim Advanced and the MediaQ chip is clearly shown.

CPU:PXA250/B2
PXbus Frequency:99MHz
L=1 M=2 N=4
would my CPU being a PXA250/B2 make a difference?
I love my Axim have had it since December 2002, and want the best possible performance
Thanks

okay...I tried it and I got the 99MHZ bus speed on my stock Axim PXA255 along with the L=1 M=2 and N=4. So how doees one go about changing those parameters and what is Pocket Hackmaster?

The PXA250 is generally regarded as having a 99 MHZ PXBus whereas the PXA255 is capable of a 199 MHZ PXBus.... however, as I read the two developer manuals from Intel, I see settings for the PXA250 that include PXBus of 118, 132.7, 147.5, and 165.9

But I would caution that those settings ma or may not be usable as they overclock the MEM,LCD frequencies. If you do choose to overclock:

1) do so at your own peril
2) stick with tried settings for your handheld and processor
3) have a backup, or two, or three, etc
4) don't overclock what you can't afford to lose.

The short answer is that PPC2002 seems to run both the PXA250 and the PXA255 at 99MHZ PXBus so I would not worry about it too much. The PXA255 is capable of a near 200 MHZ PXBus but there are trade offs. If you want to boost speed, check out some of the better known overclocking programs such as Pocket Hack Master ( http://www.pockethackmaster.com ). I have Pocket Hack Master, Axim XScaleCTRL (I think that is the name), (and just found it on my network drive) TurboTray (a free one). I personally prefer Pocket Hack Master but if you want to boost your Axim with the least trouble and don't care about autoscale, AximXSCaleCTRL uses a simple slider bar up to 500 MHZ just for the Axim X5. I don't use this one anymore because they did not release an update for the PXA255 and in emails they told me they have no current plans to do so.

Hope this helps.
