XCPUScalar with treo 750 - Palm Treo 750

Has anyone tried overclocking their treo 750?
does it work ok?

it seems to run fine for me @ 400 Mhz, which is 88Mhz faster than normal.. No problems, ive had to soft reset a few times, but who is to say that wouldnt be the case any way with this device? =)

have you tried to play Call of duty?

jefe, are you sure its overclocked?
the treo 750 runs a 300mhz samsung processor.. but xcpuscalar is set to only work on TI OMAP and XScale processors..
figure id ask anyway before trying ;d

XPUScalar would let you know if the processor was supported. It is an XScale processor even though it is produced by Samsung, and on the side of the Cingular box that it is sold in (since i work at the store) it says 312Mhz processor.

Overclocking issue

ive had my wizard for well over a year now, during that time ive used overclocking apps for at least half the time. in that time i have NEVER been able to overclock my wizard past 234mhs. anything higher will instantly lockup my phone.
i bought my phone used off ebay, when i got it, it had a clean official install...though im sure it was just a result of a clear storage whip.. ...any thoughts to why it would overclock past 234?
thanks for your help!
Because
Not all chips are the same, that's why they're under-clocked to make them all equal. It's not like there is a manufacturing process that determines clock speed. So your chip is on the low end.

Asus P750

I think this phone beats kaiser,
What do you guys think?? Actually i hate the performance of my wizard and hermes and i just heard that kaiser is not much faster and responsive then hermes.
See the specs here http://pdadb.net/index.php?m=specs&id=804
Do you know when will this be released.
well it dont have a full keyboard but personaly thats not an issue
but what really intrest me is how
Intel XScale PXA270
vs.
Qualcomm MSM 7200, 400MHz
would play out both speed and batt time wise
Don't forget it has flash light, Fm radio, sirf III gps.
I think it only lacks the keyboard and fast USB 2.0.
well i'm not too sure that usb2 would help
when pda's cant keep up with the speed of
fast flash cards which cant keep up with fast
flash readers then
usb2 rating could just be a gimic
Then it would be perfect for me.
But then i read it can only record 15fps even after having 3.2 mega pixel camera, what do you have to say rudegar? Do you know it can record more than 15fps just like kaiser 30fps??
Thanks
Don't buy Asus P750
I had been using the Asus P750 PDA phone from March 1 till now, and this is the WORST mistake that I ever made for buying such a lousy and crapy phone.
I don't know what should I call this piece of device as a phone or as a PDA.
For called it as phone, it always hang when a call is in or you try to make call.
So how can call it a phone?
To call it as PDA, it always hang from know reason while running applications.
All I can say is, it is the worst ever mistake I can make in this year. Shame on myself.

Voq

any tips on how i'd get WM5/6 on this phone? I've seen it done on the MPx200, and since they're the same timeframe if it can be done on that, should be able to do it on this.

Multitasking: A2DP + GPRS

Ok I currently own a Herme and it serves me well for the last 2 years as a phone and music player. Pair with an iTech R35 and mortplayer it is really a great combo.
The only problem is when A2DP is active it's almost like it takes up 2/3 of the cpu time (Hermes has a Samsung 400mhz processor i think...), which makes the rest of the phone operation totally sluggish and irresponsive. Recently I join a data plan and it's almost nighmare to try and surf the web via GPRS when listening to music at the same time.
So I'm in the market for a new phone, all I want is a windows mobile phone that doesn't slow down as much when using A2DP. Perhaps you guys know a few so please enlight me as I haven't been that active in the phone market lately
HTC Touch Pro!

Check out HTC Touch Pro!
yeah actually I am quite interested in the touch pro but only little is known about it... i guess i'll wait and see when it eventually comes out

as has been explaind in several of my articles, the (old) Samsung CPU uses >50% CPU with A2DP. the situation is FAR better with ALL the other CPU platforms. That is, you won't experience such lowdowns with any non-Samsungbased PDA's.
Just to add to Menneissyys's.
I own a Hermes and also a Kaiser, and they both have different CPU platform. I got what you got on Hermes, playing music on AADP. But on my Kaiser, it only took some 10-15% of CPU time, that's for MP3s. I can even play video music and AADP streaming into my Kaiser and only chews 15-22% of CPU time.
But I don't know why it's CPU bound. Is it possible that they have different instruction sets or features? Since I believe the OS is the same, also the bluetooth stack.

see my Samsung & chipset-related articles - the old Samsung platform is by far the least advanced, multimedia-wise. It's even WAY worse than the 9dated) TI OMAP 850 and Xscale PXA255 platform. This is why it uses way more CPU to encode A2DP on the Samsung than on any other, widely used platform

Confusion with speed of pda-phones

hi!
After wandering through the main searchengines out there and having found nothing for my question, i hope somebody here can help...
The question itself is fairly simple:
Is there any way to compare the cpu of a pda phone with the cpu of a desktop pc in terms of speed?
Can i assume that 500mhz on a pda are the same as 500mhz on a desktop or am i missing an important part?
Thanks in advance as always.
Dont know about phones specificaly but in general you cannot compare MHz across processor brands or types. I highly doubt very much that you can compare directly a desktop v a phone.

In a nutshell No
The question is indeed fairly simple but the answer isnt as straight cut.
heres a basic yet informative explantion

If your computer is running as fast (slow) as your PPC, then you may need a new one!

ok... thx for this... its a good start.
so basicly i cannot compare a pda with a desktop...
its a little hard to believe... yet you guys will surely have more expierience in this matter than me...
though... before i settle with this...
has there ever been some kind of benchmark to see how various tasks are being performed on ppc in terms of speed in comparison to the desktop-pc?
it would be a valid answer for if somebody says:
"the newest pda phone is roughly as performant as a desktop with a pentium II"
OK ... if you don't believe us then you can always try your own testing
create an Excel spreadsheet with a lot of data in it and a complicated forumla operating on them: time it updating.
Load same spreadsheet onto Pocket Excel and perform the same.
Thats the ONLY way you can do it. Grab an app, perform a function and time it. Copy the same/perform the same on the other platform and repeat.
These systems use totaly diferent processors and therefore instruction sets and architecture and so a direct comparison of MHz/GHz is not possible. Indeed, you can't even compare AMD CPU's to Intel CPU's for the very same reason.
500mhz=500mhz
simple math isn't it,but it stops there...they HAVE the same frequency but not the speed (speed is proportional to the frequency,but they are not the same)
2. major thing related to speed is memory
average pda has 20-50mb of ram memory
and even the lowest level pc has 128mb which is 3-4times more
things that are responsible for speed are
1.processor (not only mhz and ghz but technology 45,65,90nm , series -pentium2 and pentium3 on 500mhz haven't got the same speed only the same frequency,architecture)
2.memory
3.bus
4.cache
5.motherboard
6.drivers (instruction sets) responsible for mentioned above
and some more less crucial things
