i like cpu schalar program better, my ppc locked up twice running at 199mhz pxbus. with schalar i get 472 mhz with 118mhz pxbus running pretty well

Very interesting... so does this mean the Axim never uses the 199 MHZ PXBus? I am confused as to the screen shot in the other thread of the HP 2215. I was under the impression that Planet II wasn't overclocking or anything.

Hmm... Still looking at the PDF.

Thanks!

i think it's safe to say that all of the new axims with WM2003 are showing 99MHz as their PXbus speed in CPUID. (Mine does.) all of them would also have PXA255s, which should have internal buses reading at twice that speed.

According to Intel's Developer's Manual, it looks like Dell did set the Axims according to spec, within clock tolerance.

I am running PPC2002 and I have loaded CPUID on my Axim. This is what I see:

CPU: PXA255
CPU Current Frequency: 398MHz
Current Mode: Turbo
.....
.....
PXbus Frequency: 99MHz
SDRAM max Frequency: 99 MHz
.....
.....
L=1 M=2 N=4

Ok, I am wrapped up in this now. I just got my unlock code for Hack Master and put in the settings described. Do I need to hit anything for the AX to take on these settings in Hack Master? I am using a 2 week old Dell with PPC 2003. I changed the settings in Hack Master, but nothing changes in CPUID. Hackmaster is still running in the background so I need to know if I need to hit any specific button to activate my new settings in Hackmaster.
Thanks for the tips. Once I get CPUID to show the new bus speed I want to run SPBBench to see how this baby runs.

I was pretty sure they did the hardware to spec for the PXA255 (I have posted a lot in defense of this view) but I am perplexed as to why the 199 MHZ PXBus is never invoked?

If you go back towards the beginning of this thread you will see a link to a thread here in Aximsite that has screenshots from an HP2215 and CPUID shows it running the PXBus at 199 MHZ. Now since it is running WM2003 and it is showing that, then why are the WM2003 Axims reported here only showing the PXBus at 99 MHZ?

Anton Tomov also thought it looked like the Axim was not initializing the new processor correctly.

I hope I am wrong. I hope it is just a glitch or the way it should be, but frankly, I thought it was something we all should investigate....

Maybe Planet II had his HP 2215 overclocked? Does anyone with an HP 2215 or an HP 5555 want to post what their stock PXBus speed it at 400 MHZ?

I agree that it looks to me in the Intel PDF like it is SOP, but I just can't figure out when the 199 MHZ PXBus is supposed to be used?

I stillt think it might be a firmware bug... but I don't know.

Royal Anguish:

I sent a link for the PXA255 earlier. I would check Intel's site for a PXA250 developer guide. In Section 3.3, you'll see a similar table for the PXA250 and it says that even with LMN set to 27,2,2, you'll still have a PXBus speed of 100 MHz. One of the advantages of going to the PXA255...sorry

FrstdOne

Here's what I've got:


CPU: PXA250/B2
CPU Current Frequency: 398MHz
Current Mode: Turbo
Turbo Mode Frequency: 398MHz
Run Mode Frequency: 199MHz
PXbus Frequency: 99MHz
SDRAM max Frequency: 99MHz
MEM LCD Frequency” 99Mhz
L=1 M=2 N=4
CP15 register0: 69052904


So wouldn't this coupled with the above message from pnmfox mean that without using an overclocker, PXA250 & PXA255 on PPC 2002 are going to run the same exact speed

Now I have to try something when I get home tonight.
L=27 M=4 N=1
Set power to Normal that way it doesn't automatically step down to powersave mode.

Dell did set the Advance correctly to L=27 M=2 N=2 so that the auto feature can step back and forth from 200MHz to 400Mhz.
Does this sound right?

I manually set mine to L=27 M=4 N=1 and hit change processor speed to... (it is the big blue click button on the upper left).

Please do post benchmarks :D

BTW: Try the 2.41 beta version of Pocket Hack Master as it shows PXBus speed... the link is further up in the thread.

Glad we're seeing the same thing, JmE. Let us know how it goes.

That is also puzzling me... I would really like to see a few screenshots from a stock HP 2215...

Does this mean that in order to use the PXBus at full speed we give up automatic scale?? If so, the new version of Pocket Hack Master with the new PXA255 profiles should do scaling all the way up... I hope.

Yeah. that's right. How did HP do it? Do the iPaqs have autoscaling?
