Upgrade Ram?

Im not fimiliar with the windows mobile OS would I have to make any software changes for it to support 128 mb of ram so long as i can find one with the same layout just higher bytes per address, and if possible can someone give me the model number for the G4 ram already installed I dont want to void the garentee if I dont have to. The omap 850 supports 128mb ram by 256mb flash but yet again I am not familiar with the layout if some one can scan a board at hires that would be great or any other advice.

Hmm... I'm a bit confused by what you're actually wanting to know. Are you trying to find out if you can upgrade the RAM on the Wizard's actual board itself?

Sorry, yes I would like to upgrade the ram on the board itself and if anyone has had any luck or even tried to do it.

You know, I've not known of anyone to attempt that yet. Unless I'm mistaken, of course. I'm not even sure that it would be possible or where one would even get the correct chip. You never know though.
But, be patient. Someone may come across this with some answers for you.

Great idea and good luck, you just might put HTC out of business on this one. Wizard forever.....

Actually I was thinking about attempting this myself. However it will take some time for me to plan this out. I am currently studying to get a degree in AASCET and one of my projects is to learn mobile repair. I don't believe this will happen until Quarter 3 though since I'm in quarter 1 it will be about 6 months before i'll even attempt this. However my guess is it should be able to work providing you can find compatible memory.

massive ammount of problems on JFS 1.51

getting read to just swich to one of the hero roms at this point but figured before i do i'll see if any of these can be fixed.
This all started right shortly after the 1.51 update
First of all, I've wipped the phone and reinstalled twice now and left the battery out and did formats and tried new SD cards and all that and these are the problems i'm having.
-Camera will not save once finished. It takes the picture but it never saves to the SD card.
-Screen randomly changes orientation by itself when the phone is not moving at all. on a table
-Lots of random crashes
-and the worst. Certain apps will only download 50% of the file size when i download them making them never work, If this happens it's impossible to ever download it. Even after wiping and reloading the phone the same thing happened again. It also happens in updates as well. Killed mybackup pro and i had to go download it off rapidshare because i needed to make backups and the market download would never download properly.
So basically, is there any way to fix all these problems or am i better off just going through everything and flashing to a new rom now.

very strange, never had problems on JF1.5 or 1.51. Have you tried flashing JF1.5? If that's still causing problems I'd try Cyanogens build. Sorry I can't help much, but you've already tried everything I would have suggested

yeah i've posted on a few forums and did everything there. then figured i might as well post here as a last resort.
I did try going back to 1.5 and things worked fine, then went to 1.51 again and everything happened again. I'd like to be running the latest release of any custom rom, and hero looks awesome so i'm thinking that if i can't fix this i'll just go through everything to upgrade to hero

There are no major changes from my JFv1.50 release, except a few new kernel modules.

Hardly anything to update for, but whatever, have fun with hero Don't flash the SPL without the Radio (seems obvious but loads of people are spamming looking for a nonexistent solution to unbrick :< )

yeah i guess. Just me being myself wanting the lastest things. And don't worry i won't do that. been reading all about it for the last few days after i decided to give up on jfs 1.51
thanks!

The Hero build certainly looks nice, but it might take you a while to get used to the slight slowness compared to the non-Rosie builds. Still... very pretty, keeps me mesmerized while I wait for my stuff to load... j/k

I've been using aHome for 5 months, i'm used to lag. lol.

nothing prepares you for Hero lag!!! just kidding, with linux-swap or compcache, its pretty snappy, but not comparable to non-hero builds.

well i'll find out soon enough. If it ends up being really bad then i may just go to some other ROM but i'm really hoping to have hero run good. Unfortountly i just have a normal Micro SD 2GB which has no class distinction so hopefully it'll be alright. If not i may have to go get another 8GB.
When i tried to format the last 8GB to get apps2sd working one program destroyed the card. shows up as 8MB now instead of GB. lol.

use cyns rom. most fastes freshes bestes cupcake ever. even tastes better. and his recovery also.

there is a way to fix that on linux mentioned somewhere here on the forums...
it involves just writing 0's through the card

I too noticed alot of lagging in jf1.51 after moving all apps to sd so I took off Ahome and openhome and it runs alot better. I also need to get a class 6 sd card which will help speed things up. currious...does anyone know if there are limitations on the size of the sd card for G1? I looked on HTC's site and T-mobile's as well it just says micro sd 2.0.

didn't know that. guess i'm gonna have to grab that and try to fix my 8GB
and i thought that the G1 was capped at 8GB but i've seen people say they have 16GB cards so i guess you can go up to 16gb. which i think is the largest they make in micro sd

swap how it works not how to set it up

i have not stayed as up to date with all the advancements on the g1. so im asking about swap and how it works i read how works on like desktop and ect but i did not fully understand it. also tried looking a some threads about again could not really find anything on how it works. i get that its kind of like extra ram but not really. i guess im wondering how its not like ram i understand that its not hardwired and that can create issue is that the only real difference? and why can too much give you strange lags and ect? any reply would be of tremendous help

on that subject please explain swappiness 2. how to check and change swappiness. i understand u can change swappiness with terminal with code: su
then
echo xx > proc/sys/vm/swappiness
but how to check the swappiness?

I actually pull the file and look at it.
Code:
su
cp /system/bin/user.conf /sdcard/user.conf
Then once you edit or do what you will now we need to move it back.
Code:
cp /sdcard/user.conf /system/bin/user.conf
Then i use "Text Edit" to look at the file and read the swappiness.

The swap is something like Virtual Ram. It helps the G1 run things like Hero or make cupcake faster. Its something that the G1 lacks but most other android devices will have. You'll need to set up your SD card in the following order. Fat32/Ext2-3-4/Linux-Swap. Most ROM's will use the swap automatically so there's nothing extra you need to do.

ok i get that. and i dont think that any of the new phones will have this until there is larger internal storage. but i could wrong. but my question that remains is why a swap partition of 128 or so seem to create odd lag problems. and most devs say 32 mb is most stable so a little information on this would be nice.

Hmmm I've acutally heard good things about 128. I haven't gone over 100mb for Linux Swap and it's actually pretty smooth... I would stick with that and if you want more speed increase your swappiness And that's the thing when rooting your phone like we're doing. It's a clear example of "Results my Vary" What works for one person may not work for another. I would use a linux-swap that works best for you. Try using 64 or 96mb.. see if that works better for you.

i haven't done much experimenting because i have not had a complete understanding of it but i am getting there. and i had to get a replacement g1. im going play with a probably burn out a card or 2. but still i would like to know why too much room in the swap partition can make issues and also i was wondering if the size of the card matters in relation to size of the partitions.

Some of the ROM's just have a hard time. I don't think there's an exact reason. (someone correct me if I'm wrong, I've looked myself) It's weird because some people have great results and others it's just awful.
When it comes to your SD Card It doesn't matter the sizes as long as:
Fat32 Can be the remainder of the card
EXT2/3/4: 1.5GB or less. I've read that any higher and the ROM's freak out
Linux: This can be 128mb or less. Either create a 32/64/96/128 size partition and you should be fine.

do you mind if u can dumb it down for me a lil cuz i have been trying to figure out what the helll swappiness means and i cant find any good explanations. heres what i got so far, correct me if i am wrong. basically, as mentioned, its virtual ram. this virtual ram comes from ur SD card. so when our phones internal ram is not enough, say like on my MT3G, then the ROM, hero in this case, will use the SD memory as RAM. right? ok so whats the point of needing 3 partitions? why is this linux one so freakin important? and what do u mean by swappiness? do u mean just how much mb u are using from every partition?

from what i understand... (which isn't very much)
a swap space is used like ram (like some one said earlier virtual memory) the reason a larger swap space is not as stable in the long run is that once the space starts to fill up more it has more to read through and swap between the swap space and the phone.
swappiness is the rate at which the info is stored in the swap space. its measured in 0 to 100. 0 being the lowest and 100 the highest. the higher the number the more the swap space is used but also the faster the swap space will start to fill up.
i hope my mediocre explanations are not to horribly wrong

It'll use it in addition to the internal RAM.

Click to expand...
Click to collapse
Fat32: Needed to keep additional files on. Storage, music, pictures, ect.
EXT2-3-4: This is used in conjunction with the internal memory. (The G1 suffers from a lack of internal space. This is the primary reason why I rooted to begin with)
Linux-Swap: This helps improve the G1/MT3G run CupCake/AOSP/Hero a lot smoother. This works as additional RAM for the unit.
why is this linux one so freakin important?

This helps run ROM's on a phone that it shouldn't be running on. IE the G1 Running Hero

this thread has been very helpful to ne thanks to all those who read it and gave me some info i hope it helps others as well. i got a g1 in the mail today (hope its new and not referb) but im try this this weekend and see how works. but im going try look into and understand why the size matters little more. because i dint think anyone knows.

thank you so much nolimit and everyone else for helping me understand this. i really do appreciate it. it all makes sense now!

Change 'Low on Space' threshold?

Is there a way to change when the phone starts complaining about low space?
I have 6MB free, which I think is reasonable, I
I used to be running apps2sd (on CM-4.2.14.1) with a 8GB class 4 (has the 4 in a circle) 'cause I was a total app whore and my phone was ridiculously slow, so I got rid of the ext partition.
**edit**
Also is there a way to reduce the numbers of 'home screens'(?)?

No it will continue and that is a feature of the andoid OS. You should upgrade to Super-D and get a EXT and it will be fast again. But your SD might be dying or is a low class so it would be slow. I'm pretty sure it could be changed to a lower amount though.

No, and to continue to beat a dead f-ing horse:
<edit>Please</edit>Don't post questions in the dev section.

Because the ram hack takes away from 3D, the performance is actually worse off than helped.

No it doesn't because most CM followers want cool toys instead of stable phones. I don't play 3d games either, so there's a sacrifice I'm willing to make, but they don't understand that. I'm working on one, but with the job and family, it will be a while. I'll post it once it's stable.

That is no longer used, due to the fact that the new kernel branch isn't compatible with the ram hack at all. A kernel dev would have one avail if it was possible to make one.

You people are all missing the facts in this;
The reason there is no 10 MB hack is NOT because it isn't possible, or even because it is difficult.... it is because ECLAIRE DEPENDS ON 3D much more than previous android versions did. Take away 10 MB from the GPU and it all turns to crap -- whether you 3dgame or not.

Oh dang, shoulda known king lbcoder would come in and correct everyone.
Anyway, since we have no 10mb ram hack, we use compcache or a swap partition (at least on G1's) to make up for low memory. But this might not be fact...just what everyone is doing in the G1 Development Forum.

I suggest not using swap.... it is quite an ugly hack for android -- makes things slow. Let the android memory manager do its job -- it is very good at it.
