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.

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
and what do u mean by swappiness?

Swappiness is the speed that the ROM can access the LinuxSwap Partition
do u mean just how much mb u are using from every partition?

This one I didn't understand..

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!

Does CM5.0.8 have a 10mb RAM hack?

If it does can someone give me a link to where i can find it?

No it does not. This is why we use Compcache or a Swap partition on our sd card.

No, and to continue to beat a dead f-ing horse:
<edit>Please</edit>Don't post questions in the dev section.
<edit>Please</edit>Do your own research. This has been brought up before and has been explained.
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.

yeah it does a HORRRIBLE job haha, dont try it

If you're using ADW Launcher, try locking home in memory from spare parts. It fixed that issue for me.

nevermind found it.

No optimizing more than 90% SD Note 8

Hi, is anybody having issues with the phone not optimizing more than 90%?

The last 10 is for activating the antivirus.. Just ignore it... It is not needed. 90 is basically your 100

Try optimizing the memory and RAM manually. Also, if there's a program that it thinks you need to let sleep and haven't, it'll keep the percentage below 100.

It says right there, that if you turn on the anti-virus you will get 10 more points, so you will have your 100.

Curious about different model specs.

So,from what i understand there are models in the East that have 6gb of ram and then the rest of us have 4gb variants. Now what im curious about is this,are they exactly the same internally excepting for the ram difference or are there other differences? If they are exactly the same,is there not a way to add the extra 2gb of ram to a 4gb ram device?

Because the RAM is solded on the motherboard, is not a modular component like on a PC.

Thank you,but could one not replace said soldering with the 6gb and solder that onto the board? Sorry,but im just trying to figure out if it isnt possible at all. I know one could replace the whole motherboard,but to do that,you could just as well have bought a phone with the 6gb ram already in it.
