Dear all,
Do you know the overspeed for the O2 mini software Pocket Hack Master, attachment is full version share for all O2 mini fans
Good? Are U sure U can o/c yr jam stablely? So far, I don't see any o/c software run stable on jam.
I tried running my mini at 520mhz using pocket hack master. It ran quite fast indeed, then it did a hard reset after about half an hour.
I didn't bother to re-install hackmaster after that, but before I tried overclocking it, I was experimenting with underclocking it to see if the battery life would be extended. I didn't run my experiment long enough to see tangible results though. Anybody else tried underclocking their minis/jams?
xcpuscalar
i always use xcpuscalar, to underclock and sometimes overclock my jam.
it works fine, and i think its easier than phm.
I did use PHM and uninstalled it. The thing is, that, for most cases, overclocking isn't neccessary at all. It only brang me some faster game speeds for some (!) games. But that's not worth it. The increase in speed is only slight. The disadvantage is the battery drain with PHM, even when underclocking resp. using the scaling possibiltity. Both drains the battery a lot more than without PHM running at 416MHZ. The problem is the voltage regulation which isn't working with PHM but which the CPU is regulating itself very well, when left alone.
So, if you aren't 100% sure that you need (a bit) more speed, forget about it.
Guys,
Have you noticed that when you try to overclock the JasJar past 520mhz it freezes and then displays a blank blue screen.
I was attempting to overclock it to 624mhz using Pocket Hack Master 2005 and XCPUScalar (latest version) when I noticed this.
It underclocks OK though... (416, 312, 208 etc)
Through research I'm aware the the Intel Bulverde (pxa270) should have the ability to overclock to 728mhz using the to 2 mentioned utilities.
Has anyone else experienced this?
Anyone else experiencing this????
Anyone????
Patience dear boy.
Considering how new the Universal is. Very few people have them at the moment. Even fewer will have actually tried to overclock them.
I will give it a go tomorrow.
maybe wait a little for a wm5 update
Thanks Rilot!!
I guess your right - need to give the device time to mature...
Have you had any luck on the VGA hack you were working on?
Having problems with the VGA hack.
I can get the device in to low DPI mode (what we call real VGA mode) but I can't get the icons to work properly no matter what dlls I use. WM5 seems to throw a fit every now and again when running in this mode.
I think I may have to defer this project to someone with greater knowledge of how WM5 does it's stuff.
I see...
WM2005 seems to be very very touchy about things...
I am also looking into "Real VGA" mode - as I learn more I'll post my findings...
Thanks for the support
I am running 624 MHz
I used Pocket Hack master 2005 (V3.15) and managed to overclock to 624Mhz
Bus 208 RAM 104 LCD 104
Giving me
SI 372 MIPS 261
Which beats the 520 clock's
SI 341 MIPS "17
noticed that today screen refreshes much better and overall noticably more responsive!
cool
MrGinger,
Did you test 624mhz using the "speed configuration" in Pocket Hack Master?
Did you use the 624mhz option thats already there or did you create your own 624mhz profile?
Yes I used the speed configuration in pocket hack master.
I used the preset one under "filter > generic > Intel PXA270 Official"
At the bottom of the list
624 208 104 104
Tested fine for me (multiple times so not a one off fluke) and is v.stable... is it giving you problems?
Bombs out with blue screen on 728 though!
I just did exactly that - used those exact settings and it displayed the Blue Screen and froze... Soft reset required...
Are you using and Imate JasJar from expansys as well?
My device information is:
ROM version: 1.12.38 WWE
Rom date: 08/24/05
Radio version: 1.03.00
Protocol Version: 42.36.P8
ExtROM Version: 1.12.120 WWE
Are any of your device Software revisions different to mine?
This is admittedly frustrating me a little...
probably less stable
This is dodgy so probably means this is not too stable will let you know tomorrow!
tried 728 and boom
soft reset then into speed configurator
filter > generic > Full
takes ages to render but I tried
676 208 104 104
and it worked!
So I went down to 728 208 104 104 like I did before but from the full list
AND IT WORKED!!
Wait a mo (5 mins later)... just tried hot swapping to 728 from today screen and BOOM this is not at all stable on mine
Also noticed that SI score was 318 as was the 676MHz score, both bad as 624 had SI of 372...
My gut feeling is the thing only like 624 tops
..... just tried hot swap to 676 and boom aswell...
624 is the only stable overclock on mine!
hope this helps
Question: wil overclocking chew through my battery life?
sorry missed your last post.
Mine is same as yours
jasjar from expansys
have 2GB momy memory sd and voda sim
running sbp pocket plus not that it should make a difference
rom 1.12.38 WWE
date 08/24/05
radio 1.03.00
protocol 42.36.P8
ExtROM 1.12.120 WWE
exactly the same as yours
got mine delivered last friday
this is weird... i can feel your pain
Yes overclocking does take its toll on the battery life.
But I find it extremely useful to dynically set the CPU according my personal usage patterns.
For example on my MDA3(IMate PDA2k, O2 XDA2s) I would underclock the processor to 200mhz when it was on standby and overclock it to 472mhz when working on it.
I going to try your settings now and see what happens...
BTW - you help is really appreciated.
May not be relevant but if you have XCPUScaler still on your jar try removing it first then soft reset then pocket hack speed conf
just trying to think of suggestions.
signing off for the night. I'll check in tomorrow
Thanks MrGinger,
You have been very helpful - Really appreciated
I'll look into this further tomorrow and post my findings.
overclocking
Is there a chance of frying the mobo by overclocking, I did that once with a PC, I dont want to ruind such a pricey investment by gaining a few seconds of load time thought
nabil2000,
The Intel XScale achitecture allows for speeds in excess of 624mhz.
The fastest stable speed I am aware of is 728mhz on the Dell axim x50v which also features the Intel Bulverde processor (PXA270).
I am trying to make my JasJar operate at 624mhz as MrGinger has managed to get his to function in a stable manor at this speed.
MrGinger's JasJar also features the same software and rom revisions as mine.
Also I do not believe oveclocking to 624mhz will damage the device in any way.
I have owned a Xda1, 2(Himalaya), and 2s (BlueAngel).
Most of the time I had my Xda2 and 2s (PXA263) overclocked to 530mhz with no detrimental effects.
I still have the blue angel and it works perfectly. (Lost my xda2...)
Both devices were very fast and responsive at that speed - however, unsurprisingly, they didn't last long between battery charges.
qazzi76,
thanks dude,
I might consider overclocking it then, speed improvements and responsiveness are always welcome
Nabil H out
Just a short question about all this:
Is the JasJar running WM5 actually faster than an iMate PDA2K on WM2003 and overclocked to 530Mhz?
Or since4 the system is still running on ROM based Storage it still drops down in performance especially in Calendar and Contact lookups?
Can it permenantly destroy or harm it if i overclock to lets say...280Mhz?
and also,what is the best /recommended overclocking software??
thanks
You could damage your device trying to overclock too high in theory - but it rarely seems to happen. The device most often goes to a white screen and soft resets, You have to find a stable speed for your device - 240mhz omapclock speed = 260mhz real speed -seems to be stable for most people.
Use omapclockplus http://forum.xda-developers.com/viewtopic.php?t=56057&highlight=
Or batterystatus (with today plugin) http://forum.xda-developers.com/viewtopic.php?t=55782&highlight=
Or you could use omapclock with smartskey or memaid/sktools
choice is yours :wink:
I haven't had any problems so far, but am running it modestly overclocked @ 247 Mhz. I am using the batterytodayplugin, works great.
Possibly I'll bump it up another notch to 260, but for now I don't need that extra speed...
One advice - go slowly. Increase in increments, and wait a few days between each higher overclock value. That way you can determine if it is stable.
Hello,
I changed a little while ago my device from a Prophet to a Trinity (mainly because of the bad Prophet Processor overlocked at 140...)
But I'm feeling quite disapointed with the Trim as even basic action take as much time as before with the prophet... moreover, I tried some game from Resco which are lagging as hell.
I was expecting better.
Now I just looked into TCPMP oprtion and I'm seeing that the Proc clock is 100 mhz... sometime it reach 404 Mhz but it almost always 99 ~ 100 Mhz. What the hell ?
Is there some good program to monitor that behavior. Any idea of what could be the problem?
I already tweaked the device by removing animations and I also removed all heavy today plugins like SPB pocket plus...
Thanks !
try Xcpuscalar
works great u can eahter adjust the cpu speed yourself, or u can select auto scale with cpu load, and let the device decide when to provide a fast cpu (when doing a lot of things) or a slow (when just standing in standby, and save battery)
If i am not mistaken current version of Xcpuscalar does not support the Samsung CPU.
I saw someone has asked about which ROM is stable and how far can you overclocked
I have a Jamin G4.
Have flashed with PDAViet 4.0.0.0.6 Touch. I have not problem at all since.
I also used Battery Status and overclocked the CPU up to 286MHz... it runs ok so far
But when I tried 299MHz or higher, the PDA hang.
TIPS for overclock:
- For safety: set
+ Ticked: "OVERCLOCK ON WAKEUP"
+ Unticked: "Remember last CPUSpeed" and "Overclock after Reboot"
- Reasons because in case if the PDA hang, a reset will put back the clock to default or 195MHz (in my case)
- Overclock less or closer to the default 195MHz is better unless you need high clock for some reasons.
I think fast clock, will use more power, therefore drain battery quicker and probably shorten your CPU lifetime
I hope this would help to answer a number of questions for someone
