More RAM for G1, possible???

Also don't forget using your SD card as swap partition will thrash it and could shorten the life of your SD card due to alot of writes.

If you really want to do this look for a program called 'swapper'.

do you know how windows vista can use external memory and make it into additional RAM? well can the G1 be programed to take memory from the SD-Card and turn it into more RAM?? I know that it might not work but its worth a check!:)

IF your not sure about it check this it will explain ((http://articles.techrepublic.com.com/5100-10878_11-6039379.html))
This is pretty much the function the swap file provides. There is a differentiation on a desktop because on a desktop files are stored on a hdd, whereas a portable device usually uses flash as its storage and swap.

And just to clarify, Vista readyboost is completely different to RAM or swap partitions.

Flash memory is limited to a certain number of writes, it is a very large number so in normal use you will probably never hit it. Reading however will not affect the lifetime of your flash memory.

Hard drives do not have any such limits.

Readyboost uses an SD/USB memory card/stick as a cache to quickly load frequently used files, this is because it's generally faster to read from flash memory than from the hard disk. Readyboost DOES NOT write very often, this is why it is suitable for use with flash memory.

Swap/Paging/Virtual memory is completely different, it is an area on a disk, a file on windows or a seperate partition on linux, where the operating system can dump some of the data that is in RAM if it runs out of space. If you have low RAM or are using high memory applications this will do alot of reading AND writing, therefore will reduce the lifetime of your flash memory. This is why swap partitions are normally on hard disks.

Hope this helps explain it!

Sure they do. Just considerably longer. Also, hard disks, for quite a long time now, have been capable of dynamically remapping around worn out sections and come with a decent chunk of unused space that is used for remapping. Hard disks also suffer from gradual demagnetization -- over time, the differing magnetic fields on the platter will interact with each other, causing data loss. You can generally expect a finite life time of any hard disk before large sections of the platter become unusable. I have noticed this particularly to be the case with winvista, which by default likes to catalog and recatalog your disk (they say for fast searching), but the end result is writing and rewriting of the same small portion of the disk, which causes it to wear out VERY quickly, though leaving the balance of the disk perfectly functional.

there might be a way to physically remove (with a soldering iron) the 192MB ram chip, and solder on a 288MB ram chip like those on the newer HTC phones.

I really want more RAM, but I also want a keyboard. and with Android, you can't have both right now

That would be an impressive waste of time and energy but kudos if you could manage that. Best bet would be to buy the Hero when it comes out and get a bluetooth keyboard. ;)

Does hero even work on tmob 3g in the US? Looks like its geared for at&t.


I'd say replace the memory chip if you can and report back!:D

I would definitely try it (I'm an Electrical Engineer, and solder at work all the time)
But i'd rather buy a 288MB chip from somewhere, rather than rip it from a different device.
I don't wanna throw away money.
if someone knows a supplier for those chips let me know and I'll try it and post screenshots

The last 2 smartphones I have owned there has been a discussion on upgrading the memory with huge threads and a few people trying. The end result has always been it is by far cheaper to get a new phone in another year which will have a faster processor, more memory, more storage etc...

Sure it can be done but with how fast technology changes it probably isn't worth it.

Only if the HTC Magic also is, because they're exactly the same except for the shape of the plastic.

I wouldn't give up the keyboard.

the htc magic isn't exactly the same. Some htc magic models (like google ion and tmobile mytouch) only have 192megs of RAM.

My understanding is that apps are limitted to 16mb of ram anyway. The real problem is the data rate of the ram. Some have hinted that a class 6 sd card is just as fast at read/write as the phone's ram. So more ram in theory won't really help if it's still limmited by read/write rate speed. More internal memory would be nice but again won't make the phone any faster, just help with our 'out of room for apps issue'.

Perhaps on the hero motherboard buss speeds themselves are faster but I doubt there's much we could to speed up the dream :/ someone please correct me if I'm wrong tho..

You are probably confusing internal FLASH with RAM. A class 6 uSD card is NOWHERE NEAR the speed of the ram. The RAM is orders of magnitude faster.

Reminds me of the days when people soldered on extra RAM on the XBOX1 to increase performance when using XBOX Media Center!

I thought there was a technical manual out for the G1 somewhere that listed parts... Not just the service manual which showed you how to open the device for repair. Could be worth running a decent google search for the motherboard and parts and then find a supplier for the RAM if you're game in trying to solder more on.

Thanks to the flexibility of Android as well, I'm pretty sure it would be able to read and make use of the extra RAM too.

...this is exactly what I thought...

With the recent rumors of the g1 not supporting donut due to its lack of memory... this mod is number 1 on my list... I plan to do this soon... any one else?
