It was a Pda Repair shop in Bangkok, Thailand (recommended from a friend) who did the soldering for me. I am lucky enough to be here for holiday, so I decided to give it a go. Having the chips with me, I showed the upgrade instruction from wiki to the experienced guy who did the work for £6. If you are not there, it could get a little tricky since the normal Thai postal system isn't very reliable (could get lost). Private courier is better but rather expensive.

Among these "technicians," I would call them, soldering chips doesn't seem to be a big deal. This man managed to get the chips soldered in less than few hours. Moreover, the chips we are talking about have been widely used in many pdas, so a lot of technicians should know it well.There should be plenty of people who could do it, but finding decent contacts could be more difficult.

Please PM me if you still want the contact for this shop. Don't know if they speak English very well though. :)

Best.
[JASJAR, XDA Exec, MDA Pro Software Upgrading] mctoey:
The 64MB chips have been widely used in a lot of previous pda models running WM2003 and early WM5, for examples.

It is quite surprising to know that such a powerful device as the Universal needs lower voltages in specifications in its working. Moreover, these chips can operate within ranges of voltage, for example, between 2.5v and 3.6v. I would guess that the original chips should do the same?
[JASJAR, XDA Exec, MDA Pro Software Upgrading] scholbert:
Hi again,

sometimes it's really amazing. Seems that no one thought about the bus voltage before!

It is also interesting that there are some device with 128MB soldered that run like hell!

The Universal uses 3.15V for I/O, 1.8V on its internal bus and 1.2V for the core. So indeed Silto is right, saying:

But to get back on track, there should be some parts that work with this voltage.

I think the K4M51163PE-BG75 should do the job.

It should be no difference if you got 2x4M (dual die) or 8M (single die) as long as the memory is 16Bit wide and also got 4 Banks!

Another one that should work is HY5S7B6ALF from Hynix.

Any other comments about this?

scholbert
[JASJAR, XDA Exec, MDA Pro Software Upgrading] mamaich:
someone have told me that these chips just run slower on 1.8v voltage. But this is unnoticeable on my device even when I've made special memory benchmarks.

And there is one resistor that can be changed to increase RAM voltage - but noone have tested that.

I've finally got a G4 device, so in a week or two I'll publish a ROM compatible with it.
[JASJAR, XDA Exec, MDA Pro Software Upgrading] Silto:
Hello scholbert,

to use the K4M51163PE-BG75 ( mean 8M x 16Bit x4Banks) is not so easy.

The reason is, the PXA is programmed to use 64MB on one SDCS-line. This mode is called ?Normal 256MB Memory Map?.

The PXA has four SDCS-lines. The dual die device is use a second cs-line, which is activated by the new .nbf ? File (with a ?simple? change) and a 0 Ohm resistor. To address the RAM (2x 4M x 16Bit x4Banks) you need one off both CS-lines, the select of four Banks and a multiplex decoded address part with 13 rows and 9 columns.

To use a single die with 8M x 16Bit x4Banks you need only one cs-line, the select of four Banks and a multiplex decoded address part with 13 rows and 10 columns!!

To use the Mode ?13 rows and 10 columns? the PXA must be run in a special mode which is called ?Lage 1GB Memory Map? and in addition it must set the address multiplexer (SDRAM-Controller) to Mode ?13 rows and 10 columns? and set a new refresh-time for the bigger RAM. (In this mode one of the SDCS-lines can address up to 256MB SDRAM).

I?m sure it is possible to use a RAM with 8M x 16Bit x4Banks in the HTC Universal, but I need more information about the ?third? SDRAM in the system (K5D5657ACM). If it connected to the PXA an the PXA is switched to the ?Lage 1GB Memory Map?, then the address space of this Ram is moved to a other area. And this needs more bigger changes in the Boot loader.

Is here anybody, which can write me the connection and the function of the K5D5657ACM chip in the MDA Pro-System? (I don?t need the Datasheet of the device!!).

Thanks

Silto
[JASJAR, XDA Exec, MDA Pro Software Upgrading] scholbert:
Hi Silto,

i think you're right!

Grabbed the PXA270 developers manual again and had a additional look into the SDRAM's datasheets. Thanks for clearing things up!!

As far as i investigated the Universal architecture, this chip is part of the Qualcom MSM6520 3G Chipset (GSM/GPRS). It seems that the K5D5657ACM is used to store the Radio ROM as well as allocate SDRAM to the Qualcom subsystem.

The 3G part of Universal maybe very similar to phones that use the Qualcom chipset as their base system (have a look at the schematic of Samsung Z300).

In this phone a similar chip is used for the complete firmware (Samsung KBE00F005M).

So i don't think you'll have to modify any part of code in K5D5657ACM to change memory setup for the PXA270 system.

If i'm wrong, ...experts welcome!

Best regards,

scholbert

Hi,

Power Issues

I have been using my G4 128MB RAM for a week now. There is one power-related issue which might be related to the new chips and the power supply, or just the battery itself. Sometimes when my device woke up from sleep and battery around 75-80%, the device would faint and soft reset itself. But after then it would work ok. This did not happen before the upgrade.

This sounds like a typical worn out battery issue. So far I have been using Sino-Cameron standard battery (I know it doesn't have a lot of good feedback) for 5 months with no issue so far. I have a habit of always plugging in my universal when using it at home or office. So, battery hardly drops to a low level unless I am out for a long day.

Battery starts to wear out, or would it be because of not having enough power to power the increased ram after soft reset?

[JASJAR, XDA Exec, MDA Pro Software Upgrading] wtpelzer:
Probably...

Well you could do it I suppose you just have to find out if the OS in the ROM restricts your PDA from seeing the extra 64MB of RAM, though that said you also need to find some compatible RAM chips and someone to solder them... So to sum up, it should be possible but whether it's worth it without someone like Maimach to do the technical side of things is debateable... :)

[JASJAR, XDA Exec, MDA Pro Software Upgrading] wtpelzer:
I've used Retronix, when I did it about 18months ago it cost me about £166 for two Uni's to be upgraded to 128mb. Now to clarify a lot of the rumours going on in this thread. The extra chip slots are not for the memory, I can't remember what they're for but not for the memory! You need to get two new higher capacity BGA chips and have the old ones removed and the new ones soldered in place, don't try it yourself because you would need a hot air soldering station and and xray machine to check the soldering of the chips. Any other method you risk damaging the motherboard or the BGA chips or both.

The other thing is that Mamaich made the change to the XIP portion of the base ROM most of the chefs are using to enable the OS to address the extra RAM, it is theoretically possible to put even 512mb of RAM into the device but that would require changing IPL and SPL and involve a lot of calculation...

Hope this has cleared up some of the confusion. Any mistakes I've made above are my own, I've moved on to using a diamond but still have my trusty Uni as a spare. Though as I said I upgraded it a long time ago... :)

willing to try bga solder job, need mem chips

I have hot air solder equipment at work, and I'm willing to give a shot to the memory upgrade, but I can't find the memory chips. I tried google, but the only place listed (I checked them all) that didn't charge a referral fee won't talk to me because I'm not buying them by the thousand. If any of you are interested enough in upgrading your memory, help me find the parts. If it works I intend to offer the upgrade service, (for a fee of course), (will void warantee of course). I read some of the data sheet, and there will probably need to be a firmware patch, since the memory chip has control registers to enable it, disable it, put it to sleep, etc. So if we can find the parts, is some senior member willing to help with the patch job?

(P.S. the universal I bought has a white screen problem (only shows white), I've disassembled it and reassembled it hoping for a loose cable but no luck, so I have to wait for the lcd cable to show up from china)

Do I put it on the board or the chip. The board, right? The hot air gun, do I direct the air under the chip or on to the top? What temp air should I use, and for how long?

Then as long as I'm asking questions, if anyone knows where in the code the memory initialization code is, that would be a big help. I have to read the data sheet more thoroughly, but ut in the meantime, will I have to modify the sleep function to put the memory to sleep when not in use? If anyone has gone that far, is the code in place to support the memory or not?

I still think it will be kool to be the first to own a uni with 128m or ram.
