Anyone capable of doing such upgrade??? guys Mogul needs a memory boost to be an ultimate device. it must be possible to preform a Ram upgrade lets brain storm this and make a step by stem mod chip like mod or even some one could start a service perhaps.
what is needed......

Someone with intimate knowledge of the memory map and microcode for the Qualcomm processor inside. This person would have to determine if there is sufficent address space above or below the existing RAM and impliment it in a new firmware flash. I am wondering myself if the reason for the small RAM might be that there is or was no address range available for it, or just maybe short sighted designer decided that this was all that would be needed. If the latter is true then it would be possible. Lastly I would mention that a really good station and tech would be required to change out the RAM for a larger chip, assumeing that one existed in the same package. Might have better luck doing a RAM based add to the microSD slot by adding to a custom engineered card. If someone did that then the applications could be mapped to addresses that already exist and are known. You would end up with a microSD card with maybe 4 gigs of flash and a few gigs of RAM ??????? That might be easier. Food for thought.

Wallaby has a 32 mb built in memory. How can this be increased. If so How MUCH & How?
Note i have installed a 128 mb SD card and have installed most of the softwares on it but my system shows low memory while the SD card is nearly 50% empty.
I have tried to use the slider in the settings to increase the momory but it slides back and is not releasing more memory for the system.
kindly advise how to increase the momory

There is a company that adds physical ram to the phone but now that prices for the xda 1 are so low I would not consider that as a realistic option. You could maybe buy an xda 1 with 64 megs of memory and a broken screen and transplant the mother board to your phone.
I think he might not know that he might free up some memmory on his devices rom. If I were you sir, I would sync my data (not backup), hard reset, reinstall everything into where I wanted it, and resync. If you have experience with hot air rework, or have a friend, you might aquire the chips and do it yourseld. THen again, if you didn't know you could add memmory to a wallaby, then you probably shouldn't do that. Be careful and good luck!
PS I'm not responsable if you junk your device, I am only giving suggestions of what could be done, not telling you it should be done!
Even by physically adding the memory chips you can get only 64meg, anything above that has to be software driven paged memory I think, bit like using a fast sd card.
I know that 128+ mb requires a driver.... I wonder if you could get in 96 somehow???? anyone done that?
I think the hardware limits direct memory access above 64.
can the chips be stacked? I thought I had read that somewhere; cut a certain pin(s) and solder/joint a second chip ontop of the origionals?????
are the user accessable ram and rom on the same chip or are they seperate chips?
could the rom size be increased? (never looked into it)
Where would one acquire the chips?
is it possible to upgrade our hermes to 128mb of ram??
anyone done it yet?
I've seen somebdy changed in China..
I ve seen a thread in my home's forum, and the key of RAM upgrade is that we must find a technical manual for Hermes' original RAM and the RAM series that will be supported by the mainboard. If u've done this and have got a RAM chip...do it.
Na, i've found the thread.
I'll translate them into English line by line
I placed a pic of Hermes' RAM in attachment.

HTC Hermes （CHT9000）系列的产品采用的是 三星 K5D5657ACA-D090 估计可以换成同品牌型号类似的字库 ，至少 HTC 公司内部有人就成功了
HTC Hermes uses product of Samsung K5D5657ACA-D090, and it may be replaced by the same product. At least we have some successful examples from a staff in HTC.
Samsung K5D5657ACA-D0900
The K5D5657ACA is a Multi Chip Package Memory which combines 128Mbit Nand Flash Memory and 64Mbit synchronous high data rate Dynamic RAM. 128Mbit NAND Flash memory is organized as 16M x8 bits and 64Mbit SDRAM is organized as 1M x16 bits x4 banks. In 128Mbit NAND Flash, a 528-Byte page program can be typically achieved within 200us and an 16K-Byte block erase can be typically achieved within 2ms. In serial read operation, a byte can be read by 50ns. DQ pins serve as the ports for address and data input/output as well as command inputs. Even the write-intensive systems can take advantage of FLASH¢s extended reliability of 100K program/erase cycles with real time mapping-out algorithm. These algorithms have been implemented in many mass storage applications. In 64Mbit SDRAM, Synchronous design make a device controlled precisely with the use of system clock and I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable burst length and programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications. The K5D5657ACA is suitable for use in data memory of mobile communication system to reduce not only mount area but also power consumption. This device is available in 107-ball FBGA Type.

is it possible to get the chip from other htc model?
i have a number of bricked htc himalayas, blueangel, even universal.
what about from hard drive? or computer ram?
Could you post the link of your home's forum here? Cause I am very interested in this upgrading for Hermes!
By the way, I can read simplified-Chinese!

you may not read this thread until u've got ID.
Problem is, because this is an FBGA type chip, it's a PITA to remove and resolder. You really do need special tools for it.
Since TYTn II is the upgrade of CHT9000, could it be a reference?
Since TYTn II is the upgrade of CHT9000, could it be a reference?
I think we need to prepare at least three things:
1. We need to know if the design of the motherboard can support 128MB RAM;
2. We need to know which IC can be used in CHT9000;
3. We already have ROM that can support 128MB RAM.
I mention TYTn II is beacause we may get imformation from it about point 1 to point 3.
Suppose we can use the same chip that TyTn II is using, we can take a risk to do the upgrade.
BGA packaging is a royal arseache to try and do manually, infact im pretty sure its not possible using traditional methods, we are talking pick-n-place reflow soldering here, not using an iron.
I think, samsung processor cannot address more than 64 MB RAM.Some one posted this already in this forum.So as of now it is not possible
mission impossible

.. additionally it would be even harder to remove the RAM and FLASH MultiChipPackage from the Samsung MCU.
The picture shown above is the MCP for the radio chipset!!
Have a look at the detailed user manual.
... think wiki link to this manual does not work anymore???
P.S.: if someone's interested i may upload the manual

Is ther any way to create extended RAM.
how we have virtual memory for windows PC
i am gussing it is the same idea.
Using SD Card

It's been discussed to death. The answer is, unfortunately, no. If you really need more RAM find a ROM that uses the nueKernel to disable the camera and free up some more RAM.
i think there is a new window of opportunity with the sim card modification
i know they make high capacity sim cards
i'm sure it would be some extensive programming
i think it comes down to the ability of any of these high capacity sims throughput.
and willingness of programmers to come together

It would make more sense to me to use the already available, up to 16GB, SD card memory. If that can't be done (which should be easier), why take a more complex and harder approach? Unless there is something special about the memory on SIM cards that makes it more appropriate?
What benefit does adding a SIM card to a CDMA phone have anyway?
the modification exists to add a sim card to the mogul/titan to use the phone in asian markets to the best of my knowledge
intensive sdcard input output severely shortens its life
maybe, perhaps, these high capacity sim cards can handle higher throughput
Hi just wondering if anyone would know if we can upgrade our ram? i spoke to a online dell person they said no. but then im thinking did they say no cause it makes the phone void or cause its not possible. they told me the ram is sdram and i was thinking if you got 1gb or 2gb of sdram running at the same mhz would it work? also upgrading internal memory? give it a class 10 32gb upgrade?
I would imagine the ram is surface mount, so if you wanna take your phone apart and solder in new team, go for it.

Internal SD upgrade
I dont know if I would go as far as trying to upgrade the RAM, but I did replace the 2GB internal microsd chip with a 4GB class 10 microsdhc chip with no bumps and I can certainly tell the difference.... Boot up is several seconds faster and anything that requires accessing the card is much snappier....
Cant remember the link, but you can do a search on Google for changing the Streaks internal SD and it will take you to a thread over at modaco with a full take the phone apart route and a "cut a piece out" as I call it route.... I cut the small piece out (very carefully, so carefully I was able to glue it back in and can barely tell it was touched)
Eventually I'm going to have to take mine apart to replace the glass. At that point I'm going to upgrade the memory. I saw that article too. The general consensus seems to be that if you go with high grade high speed memory it is worth it. I just couldn't be bothered until it needs to come apart anyway.
yh i thought upgrading internal sd with something big and speedy would def benefit for games and stuff to store on phone. but would def love to have a gb or 2 of ram. who needs duel core if you got decent ram for it. i personally think duel cores are only good for big multi tasking otherwise a single core with high ram would be faster or the same
This forum is a mess...I just couldn't find better subforum or Im totally blind...
there's thing to do, maybe not actual at all, but there's lot of devices with 1gb of ram or less and we all know that android ram management is just sh** [don't try deny it, it's true]
so I thought it would be nice to create some kind of mod which will in some way replace android management and create windows phone one instead which is much better, what is needed then is needed and that's all, no filled ram with random apps.
If someone will want to take care for this project then just go on! I'm not dev, but maybe somebody will get inspired
WOW! x-D
I think Crapdroid memory managent is straightaway pathetic no matter the amount of RAM. My nearly 8 year old nx9420 T5600 Core 2 Duo, with 2GB of RAM and 100GB “slow as fukk” HDD is, multitasking wise, a pleasure to operate compared to, for example, my friend's 3GB of RAM MTK6753 UMI Iron Crapdroid phablet.
Seems to me that Android's memory paging policies are a borked pile of sh1te. Imagine if our devices where to rely on über-slow random access secondary storage (like my old computer): they would be fukking UNUSABLE I tell you.
Some wise soul wanting to elaborate on this?
Cheers
Maybe this project will ever launch on XDA because we really should do something with this mess...
I have device with 800mb of ram and now seems that skynet mod is the way, but really... I would rather windows like ram management
ehhh...what's wrong with Linux mobile world...
