Upgrade RAM?

I was wondering if there was any way to upgrade the RAM in my Mogul. I have advanced soldering skills and am not new to disassembling larger complex devices such as the Mogul and would feel comfortable doing so if the benefits outweighed the risks.
The HTC Kaiser and HTC Touch Dual both have 128Mbs of RAM. Is it possible that the RAM card has the same circuit layout and is the same physical size as the 64Mb card that is installed in the Mogul? If it is then it should be possible to swap these out and I would like to try it.
Does anyone here know the exact specifications of these 2 on-board RAM cards?

Wow will be nice to know and where to get the ram chip if possible to swap new on.

i can possibly find the mogul specs for you
is this a service you want to offer others??

Dependent upon price and possibility, I would gladly pay for an upgrade to 128mb...

Ditto.
If it's not possible to upgrade the RAM now, make a way for it to be possible. This is the World, we as a human race can solve a problem as simple and small as this.

Pocketpctechs.com offers this service for other devices, but not the Mogul. Considering how much money they'd make if it was possible, something tells me it's not gonna happen.
That said, I would definitely pay good money to add more RAM.

So, I want PocketPCTechs to outline to us in detail why it can't be done. IF we have the technicals on why it's not possible, then this question won't be coming up time and time again.

Yeah, I'd love to hear the details too. It can't be any harder than soldering in a new damn chip. I've emailed them, but am not holding my breath for a reply.
Hell, *HTC* should offer the service as pennance for releasing this POS in the first place.

there's always "a way"... the only question is who will figure it out first. Even if it perhaps would be to use the main storage as a virtual drive similar to a hard disk on a computer, that would be awesome.
I'd absolutely pay good $ to get 128mb of ram on my xv6800.
or a 2nd processor!!

If I found it was possible then there is a possibility that I might offer it as an upgrade as long as I can get my own done (and done right) before chancing anyone else's device. I really like the titan but the lack of RAM is killing me...

If I had to guess,and its just a guess,I would guess the ram is like the ram in my samsung a920. A typical thing to see in these devices is a BGA chip. The real trick is knowing if the phone will recognize a larger one if it was soldered in.

Oh crap I hadn't thought of that.

I have sent a message to PocketPCTechs about upgrading the RAM on our Moguls and whether or not it is physically possible seeing as how the Touch Dual, Vogue, and also the TyTN II both have 128Mb of RAM.

No I'm just going to throw this out there but the last physical replacement ram upgrade i have ever seen is the wallaby, which i have.
But from my experience its always been an upgrade or a driver that cut the full potential of the ram loose. I believe with out question that the titan which i posses has the capability to be 128 hence the other phones similar to it.
How ever being that the battery status has caused me many sleepless nights on the mogul due to its make up. So my hands on theory for this particular phone is only speculation.
i have used ppc techs tsk driver on numerous phones including the sph-i700 for samsung and it was a night and day difference
I will say this that from all the the boards i have seen and all the new products there is a logical reason why they keep these phones toned down i still hit almost every one of my phones with the moloski tweak just start my mods. I would have to say that the upgeade lies with in simply because htc never maxes out any of the phones

Would/is it be possible to somehow link memory from your SD card to your RAM? Or is ROM and RAM defined under specific hardware profiles? If a hack or mod could be made to utilize 64mb of ram for program usage using your SD card...
all would be well. Just a thought. Input?

Boy did I set the ball in motion... I really hope this is possible. If its a driver issue then that would be awesome but even a Solder-in ram card would be better than nothing.

i would def consider the possibility of having a swapfile which is what you are talking about. The problem would lie in the latency with the sd card or rom i would think a 66x card or faster would work somewhat but i am not sure if wm6 already does with rom. That could be why it slows to a hault when memory is low but the idea is not new and should be something that could be done on software level to create virtual ram like i said though physical ram would be best. For an idea on the performance of sd card google readyboost as that is what microsoft calls it for vista.
p.s. You are def on to something because if they already do utilize virtual mem then it could be optimized or moved on to a high speed sd card which i think would have better write speeds then rom.

Anymore info on this? This would be great!!

Same here, but all that really means is that they're not willing to do it. I bet some enterprising soul that's willing to risk his 6800 could solder in the same RAM chip the Touch uses and it would work.
I'm willing to donate $20 or so to any serious R&D endeavor.

looking at buying a prophet.. couple of questions

I'm looking at buying a prophet, and the description says that the " Phone randomly crashes turning the screen either completely light or completely dark and require a reseat of the battery to work again. This phone is considered un-repairable by the manufacture. Phone also has unsupported customized Windows Mobile 6.1 firmware."
could this be a software issue or do you think a hardware. possibly a ribbon cable, are there parts available for these? thanks

Hello Quintman and welcome to the forum.
I have no idea where you got the information in your post but as someone who has used a Prophet for 2 years I can tell you that the phone is perfectly stable, specially if you stick with the original WM 5 ROM.
I still use and love it but I would not recommend buying this phone today unless you are looking for something cheap.
It is fairly outdated compared to most models, and has no GPS, 3G, and a slow processor.
I suggest yo post your needs and budget in the general section so people could advise on a better model.

lol i just didnt want to say where it was so everyone would bid on it. it is from ebay. i just didnt know if maybe the rom someone flashed was causing the screen issue or if a ribbon cable came loose or something worse. i was just thinking of buying it to play with it. I currently have a wizard that im selling (hopefully today) so im looking into something else. i love the different models with gps and that can take sdhc, that way i could sell both my gps unit and my mp3 player, but i think those are out of my price range (unless i somehow score one on ebay.) i cant decide whether to take a chance on the ebay one. check your pm

yes
yes

Please can i have your opinions

Hi folks
My Touch HD digitiser has gone faulty and its only 6 months old
or at least thats what i thought because the screen was not responding to touch. i am a electronic technical person so not totally naive.
I was using the wonderful NRG roms with no problems whatsoever.
I tried to replace the stock rom and spl before sending it back to HTC, but i had no way of checking it throughly because i could not get it past the calibrate screen.
Htc now want £159.00 to replace the motherboard, and they state the reason as the unit having foreign firmware installed which damaged the motheboard.
now the Htc touch HD was working perfectly apart from the fact that the screen would not respond to touch. and i admit it would run a little warm at times but nothing excessive. It has nerver been dropped. does anyone think that a complete motherboard would need to be replaced because of "foreign firmware"?
Is Htc trying to rip off their customers?
clearly the xda developers are just enhancing an already great product with their releases of wonderful firmware
this is clearly a hardware fault and not software.
please wade in with your opinions

hi, I totally agree with your statement, but if you restored the stock boot loader and then the stock rom you could say that you tried to do and hard reset of the device and because the screen didn't work you were unable of calibrating it. I think they can't prove that you used a different rom.
hope you solve soon.
greets,
Nicola

Unfortunately HTC can legally stand by their clauses with foreign software on device as having a cooked rom on device voids warranty. I know you tried to restore back stock, but you couldn't tell and if appears they have still found your NRG rom on device.
However they are hiprocrites as this does not affect the motherboard and they are just lOoking for any excuse to void warranty which unfortunately you provided.
I believe others have been in your shoes before and posted similar threads. Try searching for these and see if they can shed any light.

but how can they get away with that?
If you buy a computer (which is what the Touch HD effectivly is), then you are entitled to use any operating system you whsh. wether it be Linux, Windows or Apple MAC. and if you develope a hardware fault then this cannot invalidate your warranty???
I dont get it? also how can they say it needs a new motherboard when it is clearly the digitser which has gone wrong?

I believe someone else asked this same question in another thread, though which one I have no idea. They asked similar question about how does HTC get away with this and I believe (if my memory bank is working) they wrote a letter to them and where able to still get it under warranty (don't hold me to this though) as they argued a new rom wouldn't affect digitizer. Possibly worth having a search for if you can find it.

That Sucks.
A friend of mine had a similar problem,
He had a broken microphone,
and HTC sent a similar letter =>

You'll probably find that the digitizer is on the motherboard. Looking at it, it doesn't look like it can be separate. (Where would it fit?)
It does run a bit hot sometimes and heat is bad as you would know.

I have just read the warranty information and it states that the warranty is limited to the hardware as originally supplied,and makes no mention of any software or operating system. and by the very nature of the product it was made for installing third party software, operting system of choice ect.
in fact it reads " this limited warranty applies only to the hardware components of the product as originally supplied and does not apply to any software or other equipment".
I will persue this and post the outcome

Unfortunately "Software" and "Firmware" are two separate things. While you can install any operating system on your computer, that software isn't a part of the hardware.
In the case of smart phones (windows mobile phones), the operating system is Firmware, and not software. The difference here is that the Firmware is PART of the hardware. Similarly the bios rom on your computer is part of the motherboard hardware. To clarify, software is interpreted and run by hardware. On the other hand, firmware operates the hardware which is why changing to an unapproved firmware also means altering the hardware.
Unfortunately they have this clause in the warranty because you CAN destroy your hardware with a malicious rom, just like you can fry your harddrive, cpu and stuff with a malicious rom on your computer bios. You can have umpteen viruses or malicious 3rd party apps on your device and nothing it does can harm the hardware because it doesn't actually change how the hardware itself works. Firmware is different in that it changes internally how a piece of hardware works and in doing so, can damage it.
I do agree though, that in this case they're looking to void the warranty, but the truth is that the money they loose on one device under warranty must be covered by the profits made by 20+ other sold units (remember, revenue can just go towards warranties).

Hey man, you play the game, sometimes you lose. I took my phone apart, fallowed the factory service manual to the letter but I knew there was a good chance they would notice the missing "void" stickers and I had to pay for the repair ( for the problem that was there before I took it apart). I took it apart and that voids the warranty, so is life...

Hardware Upgrade for G1?

So I know we all like buying new phones and throwing out the old, but what if we wanted to upgrade the RAM or storage? Has anybody done something like this? Is there a way to take the G1 apart and add more RAM for super fast processing?
Can anybody point me in the right direction to do this? Thanks!

OK, im pullin out the knife..no no but seriously you better be saving up your pocket change for new sd cards that go up to 32 GB cause thats all the uping you can really do.

I know about the sd cards, but I mean soldering and the like.

find me a ram chip ill give it a try

I know i just added some sarcasm in there for ya mate, but no there wont be any flying,soldiers,fireing,making of any sorts on this relic its at its limits all you can do is OC and slap a custom os onto it.Also get a phone skin for it from skkinit if you want it to look unique..

Actually that's a good question. I have been checking PPCTechs.com on and off to see if they have anything like RAM or ROM upgrades for our G1s. No luck so far, so probably not gonna happen, although they do it with quite a few WM devices.
Does anyone know if it possible to overclock the CPU? Right now we aren't actually overclocking it, despite what people call it, we are only running it at it's rated speed and not underclocking it.

There was a post somewhere about overclocking to 700 something through the kernel

if someone can find me a datasheet for the ram thats in the phone, i have the equipement to replace them, i'm sure i can source another larger one but i'm not sure if the chipset will support it.

I have the G1 Tech Manual. Is that what you mean? http://www.mediafire.com/?sharekey=72888a5fe1278ed408f8df73f2072ed6666d6d14c3b8b109d6e38d13f15c3e80

The last 3 smart phones I have owned there has been discussion of adding more ram... and it never pans out. My 2 cents is you will be better waiting and picking up a next gen phone. The lifespan of a phone just isn't what it used to be with how advanced they are becoming.

It's really not worth the effort to upgrade the ram. Even if it was as simple as just soldering a new chip in (which it very rarely is - I don't know the specifics of the g1), this device is held back by the cpu as much as the ram and you certainly can't drop in an upgrade for that.
It might be possible to overclock the cpu, but since the g1 features no cooling system whatsoever, and no space to add one, I think you'd put it on the fast track to the scrapheap.

My best guess is that whatever chip is in the big-mem version of the MAGIC will work with DREAM. Possibly the chip that is in the HERO.
Of course note that it will be necessary to program this chip with something at some point, otherwise the act of installing a blank chip will be an obvious brick.

Have you thought upgrading your dream?

Have you ever thought to g1 upgrade, the cpu replaced 1ghz, put all the rom and ram replaced 512mb. Rom the time that the production of not so many limitations, and is not it?
If anyone knows how to upgrade, we share ah. Let g1 youth forever in.

I seriously think its a long shot. I dont think a huge group of engineers at HTC with the detailed hardware knowledge of the board, the pinmuxes, clocks etc can do it in a months time. If you want to try it, sure, go ahead.

Very possible. I was reading a thread the other day about restoring a bricked phone from the hardware pov. Still not possible, but the motherboard is mapped. However, you can't just go buy phone RAM or a new processor. Also say HTC made a phone just like the g1 except with 3 gigs of RAM, I doubt that RAM would be compatible with the g1. I hope that's what this thread is about. 3:31 A.M. ftw?

as an electrical engineering student
yes its possible
no its not feasible to do it efficiently enough to finish within ..say... 5 years by yourself

If you want to make a living of repairing phones and other electronics, it's a good place to start , even if it's very hard thing to do... If you think you will save money , you wont. The MB of the dream is pretty small and it will be hard to work on but not impossible.

Wouldnt that mean the ROMS need to change also? That would also be the hardest part, right? Not an engineering student but I am sure it is not as simple as it sounds.
I am sure there would be willing donors for such an attempt to stock RAM chips and processors and do all the work. Even if it was a bundled package with a price tag on it, I am sure people would willingly pay for it. However, the more realistic option, I think, is to be contented with overclocking the processor, if that is made practically possible. Here's hoping for the best.

I say: You can better spent your time working lets say... 80 hours to buy a new device then spent 12.000 hours to upgrade a CPU, make new drivers to handle the CPU (the same counts for upgrading RAM).
But if you haven't got a job nor a life... feel free to try. It's not like a PC with swappable parts... It's all baked on 2 or 3 chips with techniques you can't find in your own living room (it's simply too small to soldering it yourself).
But that's just my opinion... feel free to try.

Sure, been conidered. Not sure the dream is ideal for it, but i'd love it if a company were to start designing with it in mind. Maybe something more meant as a dev prototype like the zii trinity but yeah. Hell, I remember first thing I did was start looking into hardwiring a 3.5 jack because I keep misplacing my adapters.

when i had an mda varia they discovered it was possible to change the ram chip for a larger one from another device, there was a company that woiuld do it for you, thoiugh it was expensive and to do it yourself required specilised soldering equipment to remove the old chip and fit the new one.
It could be possible usually its just easier and more cost efficient though to just get a new device.

i really wouldnt say this belongs in the development section - coz put bluntly - its just fantasy
i too am an electronic engineering student - and i have taken apart my spare G1
and from looking at it - it could be done in theory, but you would have one hell of a time desoldering, resoldering and reprogramming your phone
the equipment costs £1000s to do the job correctly and there is no guarantee that it would work
like - putting a core2duo into a pentium 2 board - not gonna work
pinouts, pinnumbers, pinspacing, chip size
too many things standing in the way
