Hi,
I saw an ad on ebay about O2 XDAII with 512MB SDRAM (using SD card). How can it be done?
Thanks.
You must have understood it incorrectly. There's no way of increasing the ram memory, unless you're an electronic-genius geek

So, is it a misuse of terms by seller or my misunderstanding of the terms here?

a bit from colunm A and a bit from a colunm B
he mean he put in a 512MB sd card

whats is the difference between SD memory and MMC as my xda has a MMC 64mb extra thanks. I can buy both at similar prices
thanks
Hi,
In simple terms they both can be used. The MMC is marginally cheaper, the SD has some security stuff on it.
However I think you can only get SD in 256 and 512, and the SD costs are coming down
I want to buy a sd card but i m not sure which one is better
Lexar SD 256MB 32X Speed (about 70$) or
SanDisk 512MB SD (about 106$)
512 mb looks great choice but the other is high speed ???????????
i need your comments
sandisk is not know for it's speed as it is
but very fast SD cards will never reach their top speed
in the xda their sd interface is not fast enough
if you search the forum you'll find some guy who did some tests
think the sd card did 10MB /sec in the sdcard reader on the pc
and only about 1.3 MB /sec in the xda
not all that impressive
And for the XDAII? Waht is the speed of the port?
well i forget if it were tests made on the xda1 or 2
but arm 200 which the xda 1 have dont have a nativ interface
for sd so it use an external chip and the xcale 400 that the
xda2 have have a native interface
too bad that nativ interface is WAY slower then the external chips
pda's used to use
there were some posts before xmas about places where the xda it would be way faster then the xda2
but that was in the old forum not sure if those posts are lost now
here is a line from a writing about xscale's performance on ipaq
which i asume would be the same for xda2 unless they added a mem controller and dident use the internal xscale one
Because the XScale CPU itself contains an MMC controller that supports SD and SDIO, and that's almost certainly what HP is using, rather than adding a chip of their own. MMC and SD are very similar, almost identical. The difference is that MMC uses a 1-bit data bus, and SD uses a 4-bit bus. See, we're back to buses again. Since the XScale's controller is MMC-based, the new iPAQs will have 1-bit bus transfer rates. Hang on to your CF sleeves for big data.

I got a Billington 512MB SD card 40x speed. It is OK. Cost about SGD$245.
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?
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
Hi all, sorry if this is a bit of a noob question.....
What is the maximum RAM the SGS II can utilise. I see it comes with 16gb built in. But I have read that you can expand it by plugging in a 32gb SD card...
Does this mean that it can have 48gb, or you can only expand to 32?
Thanks....
The phone only comes with 1GB of RAM and you can't add anymore. Except possibly adding swap.
OK now for what you actually meant, you can add a 32GB micro sd card to increase the storage space to 48GB.
And to answer your question, yes, adding a large SD card it will have more storage, but not RAM. It supports SDHC-standard which goes up to 32GB (some phones support the new SDXC standard that goes up to 2TB) .
Coo!

Cheers guys... I thought it would be 48 judging by the Samsung page....
Differing reports from reps in shops. 1 said anything up to 64gb and another 32gb....
Again thanks....
BTW. What is this classed as if it isn't RAM? And the SGS II does have 16gb storage RAM built in, doesn't it?
RAM: Random Access Memmory, used to store running bits of the OS, programs, etc. Whats stored in the ram will be lost when the power goes off. We have 1GB of this.
ROM/NAND Flash Memory: Flash memory that wont lose data when the power goes off, slower than RAM, but we have more of it, in this case 16GB built in, but some is used for the OS, data and other bits.
