Upgrading RAM for JasJar

[Thunder2210]

Hi All,

Is there a way to Upgrade the RAM for JasJar from 64MB to 128MB ??

what for ? i have found no reason to do it and it will drain too fast the battery.

What for???????????????????
Because this is the most slowest PDA I holded ever in my hand.
I totally dissapointed with it.
If I install my main programs - not more - the free RAM will be maximum 23-24MB (after a hard reset it is 30-32MB), but when I use it, it decreases itself without any program running.
I start from 22.5MB after softreset, and when I use some programs it decreases (it's normal), but when I close them it is less time after time. So it is not enough to close a program. After 5-10 minutes with starting and closing some program it is 10-12MB free RAM memory without any program running!!!!!!

And what is my problem with it?
Hmmm....

For example a little complicated application (a navigation software) needs 10-15MB minimum.
So if you are lucky, you can start the program, but not more.
Don't imagine that you can use 2 or 3 (or forgive me 4) application simultanously.

That's very nice, isn't it?

Any idea to solve this sh*t?

Hi

Asukal already mounted 128MB RAM on mother board.
But unsuccessfull. Memory area does not change.

U should try to install the software on the storrage card. Demanding programs like tomtom and high graffical games work great!.

When installing the program from the PC the add programs window opens (u know from active sync) There you can choose not to install the software on it's default location.

Above all that with WM5 you can also choose wether you want to install to your storrage card or on your memory.

Think of it like this:

On your PC:
Would you install your programs on precious RAM memory? That's why we use the hard disk.

You are in a total misunderstanding, sorry.

Though there are slots for extra 32MB each it cannot b upgraded as the occupied slots are differrent than those which are left empty.Hv tried desoldering the RAM but after desoldering this fact was revealed..so :(
not possible as of now

I totally agree with Thunder2210 and others that there is a sever shortage of RAM (Program Memory) on this device.

Installing programs on SD card has nothing to do with the available RAM (Program Memory to be more precise). Installing programs on SD card only saves you the ROM (Storage Memory) which is not an issue anyways. The main problem is program memory and as rightly said by some in this thread that this gradually depletes as you work with your device after a soft reset. Try to open a very large web page such as the ones which review pocket pc devices with a lot of comparative pictures and your browser will soon run short of memory ultimately freezing your device.

However I fear that nothing can be done about this. This is probably an issue or limitation that Windows mobile 2005 operating system cannot address memory beyond 64 MB. Probably this is the reason that you must have seen recent devices where the Storage Memory (ROM) is higher than 128 MB but nothing is done about the RAM which remains at 64 MB. Unfortunately what we need is more RAM and not ROM.

I have to disagree.... What we need is both more RAM and more ROM :)

just my 2 cents:

you may remember, the first device running windows mobile 5 was the good old XDA2, which is basically an old WM2003 device with 128mb ram and 64mb rom, where only 32mb is available for the user. but: the windows mobile running on this version (modified by some brave and good people here) is able to address all the ram, yes and there are different versions available:

128mb ram for running programs but no ramdisk for storing programs
96mb for running programs and 32mb reserved for ramdisk
64mb for running programs and 64mb reserved for ramdisk
etc. etc.

while i was using my XDA2 i have preferred the 96mb ram solution and wm5 was fully able to use those 96mb. even it is an old device, can you imagine how smooth i.e. mobile navigator 5 was running with 64-70mb of free ram (and overclocked from 400 to 530mhz)? it was lots of fun! htc universal is a piece of hightech sh*t, nothing for the real world use, compared to XDA2. i still have mine only for the vga screen otherwise i would have selled it long ago.

peterI'm with You Pete. If there is a VGA-PDA-Phone with 128MB RAM I would sell my Jasjar immediately. But there are no better ones. Only worse.

[Tuningszocske]

Hm... From what do You think we will like it? It has QVGA display. We wrote that one of the most important things is VGA-screen for us. But thanx anyway! :)

[moeaboelela]

Its just the Memory on the ROM..., maybe they will have a VGA screen soon...

[Yetster]

not an upgrade unfortunatly but certainly a help is a close button that actually closes things rather than just putting them in the background,

and heres a link to the program i use
http://www.pocketgear.com/products_search.asp

its a nice little program so doesn't eat your rom and its unobtrusive so wont clog up your today screen

Can U please fix the link, it does not work.

i know from my expreiance with BA WM5 rom editing that just soldering the ram on the board is not enough, you will need to find the hex values in the (decrypted) rom file that decideds how much ram the system partitions for itself on boot.

e.g - in BA wm5 roms you can edit these values so that some of the ram is left unpartitioned, leaving it free to be used as a ramdisk.

I see no reason why if someone found these values in a universal rom, combined with soldering on extra ramchips, they could reverse the process and increase the memory windows uses.

PocketPenguin. Current plan:

imx31 533mhz ARM11 CPU with internal GPU and FPU
256mb MDDR266
2 SD slots, ATA, Phone (Although this is becoming more useless by the day it seems, looks like the Videocall option is being dropped. Which is 80% of the reason I want the thing. (I want Videocalls but hate Windows Mobile)

Go, Sign up, and put in your requests and comments, Looks to be about $600-$700 total, Although you have to put it together. It's a DIY thing, (Loopholes are so great XD)

for this, I've send a mail to PocketPCTechs.com here it is

Hi LB,

Unfortunately we do not offer any RAM upgrades for the iMATE JASJAR. The nature of the CPU will not recognize any more memory.

Comments : Hi there, I've sent my HX4700 to you for upgrading the RAM and it works great since it's back. I recently purchased an IMATE-JASJAR,so just wondering do you have any plan that to upgrade its RAM to 128MB/256MB? I really need a biger speace. Please let me know,thanks.
best,
LB.

[Ferret-Simpson]

yeah, the 270.

It's why there's only 64 in the Zaurus too, and why the PocketPenguin group chose to use the iMX31.

Basically they just don't know which resistor needs to be soldered in addition to adding new chip. Otherwise the 24th address line would be always zero.
It is not difficult to trace this on PCB.

[Lt.Cmdr.Ivan]

Oh hopefully theres some day the possibility to have 128 MB ram in the universal?

great news.
