i don't think you can stack the memory on the magician. is that what you have done? according to the ppctechs website you can't do it.

I used chips of the same manufacturer... the same series... only greater volume.
It is not necessary to modify any in ROM... as at loading OS it defines how many memory is installed. Here problem in other... In old IPAQs it is necessary to move some resistor .... A question only what:)

According to ppctechs, they replace the 64mb chip with a 128mb chip, not 2x 64mb chips. you may need to use a 128mb chip.

You have to rub the magic lamp 3 times while closing your eyes and facing north.

BTW, maybe the instructions can give you any hints in where you have gone wrong and if you need any resistors etc:

i copyed this from ppc techs:

Q: Are your upgrades compatible with Pocket PC 2003?
A: Our upgrades have been fully tested with the release version of Pocket PC 2003 and are completely compatible. On most systems, PPC2003 does not support the 128MB natively, so our proprietary driver is still required. You will need a new copy of the driver for 2003. To obtain a new copy from us, please do the following:
Install your current version of the T2T Driver and soft-reset the system. Next, go into T2T Utility, turn on debug mode, exit the utility and soft-reset the system. Then email the T2TDisk.txt file located in the \Temp directory to support@pocketpctechs.com with a note requesting a 2003 driver.

I have an upgraded JAM by PPC Techs, and I can tell you that the T2T driver is NOT needed for this upgrade. (It was needed for my iPaq 4350 that I had upgraded last year)

PS And No, I am not going to open up my JAM to take pictures

tupisdin,
I admire your guts for taking on this job. I really hope you get it running :)

Partminer.

Some days ago i tried to replace memory chips in HTC Magician to increase memory to 128mb, but i had a problem.
After replacement the system has not seen full volume.... only 64mb :(

May be somebody know how to make it?

Regular BGA RAM p/n hyb25l256160ac-7.5 x 2 (2*32mb)
Upgrade BGA RAM p/n hyb25l512160ac-7.5 x 2 (2x64mb)

Where can you buy those RAM-modules?

Thank you very much! A description on how you did it, the equipment you used for soldering etc. would be highly interesting also. If you manage to get the extra ram working this is very good news!

hi, i am new here. I owned a O2 Mini.

Like alot of u guys here, I am also using wifi and the internal memory is definitely not enough. Is it easy to open up the magician and install the ram ourselves or do we need to send it to ppctech?

I am from singapore and there is no ppctech here....

anyone can share (if best with pictures) how to open the magician and replace the ram.

thanks and cheers!

I've a little question, some time ago I've crashed my 2020, I can use the ram of this device on my s100?

Upgrade BGA RAM p/n hyb25l512160ac-7.5 x 2 (2x64mb)

The hyb25|512160ac-7.5 uses the pin E2 (which is not connected on
hyb25|256160ac-7.5) as additional chipselect (CS1). So we have to give this pin the right signal. But unfortunately I don't know where to get this signal. Perhaps from the same source as the CS0 which is on pin G9.

Thank you very much for this tip...
Everything is ok.

I did it. No i have working device with 128mb of RAM on board ;)

Hi tupisdin,

please tell us about your soldering device, prices for the RAM chips and so on. Furthermore, do you dare taking orders from forum posters here?

Cheers.

Hi tupisdin,

it seems everyone would like to know if we could perform this upgrade by our own. In my case I'd like recycling the memory from my dead 9090, do you think it will be possible? Thanks

tupisdin

5th June 2005, 11:49 PM

Yes, it possible. You can get memory chips from Qtek 9090 and put them to Magician.

Great. Care to provide us the instructions on how to do it? (Such as tools to use, memory to buy and how to solder and de-solder).

Cheers!

Some extra info on this Axim site (http://www.aximsite.com/boards/showthread.php?t=85800). Without the right equipment it will be a very difficult job.
Maybe Tupisdin can elaborate on his BGA rework and the tools he used.

13th June 2005, 11:18 PM

I want to upgrade my MDA Compact to 128MB but first I want to know how to open it without any damage... Is there anyone who can guide me how to do it ? I supose tupisdin knows exactly what to do but he doesn't talk too much 8)

Grappa

15th June 2005, 01:08 PM

I've tried but the chips are not soldered using hot air like in the normal (maybe older) phones but with infrared. Very difficult to find that kind of machines and the result is not sure.

tupisdin: could you confirm us that you used infrared?

waiting4u

21st June 2005, 08:35 AM

Many of us would really love to see how this is done, however......

tupisdin doesn't seems like speaking up regarding this...... :cry:

Well, hope that one day he wake up and "feel" like share the knowledge with us !! :oops:

tupisdin

21st June 2005, 03:16 PM

shamus

25th June 2005, 10:36 PM

tupisdin please tell me how you soldered those bga's with hot air or with infrared? And tell me please what have you put in the place you showed us on picture typical shortcut jumper or some resistor?

tupisdin

25th June 2005, 10:39 PM

I did not do it by myself.
My friend used hot air for soldering.

Place shown on picture is CS1... you need to shortcut it with same resistor.

shamus

26th June 2005, 10:18 AM

tupisdin thank you for quick answer :D my another question is could you tell me the value of shortcut resistor :?:

tupisdin

26th June 2005, 03:47 PM

0,31 - 0,33

It's same same as another.

DJW

26th June 2005, 05:23 PM

could you tell us the cost of the chips?

tupisdin

26th June 2005, 05:27 PM

45$-55$ per chip

I used partminer for order.

shamus

27th June 2005, 01:21 PM

tupisdin thank you very much for all information now I just need to buy memory chips wich will be around 100$ as you said. Is there any info how to open magician casing? Or could you write short tutorial how to do it without braking some parts :) I managed to unscrew all screws but after that didn't know how to open plactic part which covers camera and antenna, I'm little afraid to undermine it and rack up hooks. Could you tell me where to starts?
