MORE RAM - Hints to free some RAM memory

[goTouch]

I am starting this thread because when I got my HTC Diamond to use for the first time a few months ago, I got disappointed when I saw the amount of free RAM memory. Only now I started to look some tips to try to free some memory and I realize that some applications consumes so much memory and do almost nothing.

I don't know if this is the best place to open this thread, but I open it here because it could inspire some ROM cookers to optimize the usage of RAM. If this is the wrong place, accept my apologize and feel free to move to the right place.

If you guys have tips too, please, put it here.

Here are two tips to start:

Remove HTC Volume Control - ~ 1MB RAM

Use Remove-Htcvolume-by-HallengreeN.cab

Disable Dialer Skin - ~ 10MB RAM (on HTC Diamond)

Go to 'HKEY_LOCAL_MACHINE/Security/Phone/Skin' and change the value of 'Enabled' from 1 to 0.


I hope this is a good start.

[brandonhall517]

i did it on my tilt, and then rebooted, but the memory didnt change at all, even though the skin did

[nothin]

few fints for cooking:

remove every useless HTC software you have(manilas, and additional, ridiculous software)
set pp to max 6 mb(usually 4 mb is enough, 3.6 mb for wizard was optimal)
remove useless keyboards(transcribers etc.)
remove wisplite.dll - reg, trarecoenu.dll etc.
make caches smaller(audiocache, soundcache etc)
revise /windows/startup
disable tick in "sounds and notifications".
make modules from every thing that's possible(lots of tests)
avoid using upx for things that runs all the time.
remove whole lot of packs from sys in kitchen, whole wlive, and other ones(almost 1/5 of sys packs may be removed, as presented software is generallly useless, what more to say..)
remove useless today plugins
reedit graphics in kitchen(even just load, and save in gfx soft may make 'em more optimzed than generic ;p)
reedit hklm/init(>71 ones are usually useless)
use optimized tsk-s.
..and more i forgot.

basics. these allowed me to get up to 35.5 mb mem free on machine that usually have...24 mb or so(wizard).

ahh, for 6.5:

throw out titanium, remove 6.5 menu(cpr cuts) - use quick menu + startbutton fix instead - up to 2 mb mem free more.

of course, you won't get big fans for your roms there after such optimizations(you know, its xdadev, lol)...but, your machine may work better, at last...

[Söderström]

- Disable QuickGps auto update function

- Replace Biotouch.exe with a dummy
http://forum.xda-developers.com/showpost.php?p=2326848&postcount=14

You will need Dotfred's task manager to kill Biotouch.exe

for ram memory release, is much better than cleanRAM and much fast. After install
make shortcut:)

ok questions/answers are up ;)


and disableing push internet engine wil save about 2mb :)

[kancrutt]

nice thread! especially for cooker with poor device (ie 64mb RAM) :p

[nothin]

btw... i can advise using oxios hibernate - not any clean ram, etc.
it is just working.

advices stored below are useful for cookers mainly, but given reg changes may be imported onto device without problem, too.

remove every useless HTC software you have(manilas, and additional, ridiculous software)-except manila and required packages for it what else can be removed?
cannot help with that...
manilla is linked to whole bunch of SHIT(i mean audiomanager etc), i cannot advise anything, but manila and that whole soft removal for people that can manage with other(not htc/m$ promoted ones) today solutions methods.
there are plenty.

q:-wll device be slower?
hard to say - if even wizard wasn't with 3.6 mb, i think 4 mb would be ok(for qvga device, cannot tell bout vga).
generally, every rom i made was...fast. it is my rule - much mem and FAST sys.

remove wisplite.dll - reg, trarecoenu.dll etc.
-how?

just use total commander to find "wisp" word, unicode in /sys(you are searching in rgu's), then track all RELATED regs and remove, then search for "trareco", unicode in /sys and remove it too, then remove these files from kitchen..

make modules from every thing that's possible(lots of tests)
-how??
exe files, and dll files(and some other ones) stored in kitchen may be turned into modules with reversmode.
it WILL save used memory - look onto "execute in place" term on xdadev to find out more.

make caches smaller(audiocache, soundcache etc)
-how

[HKEY_LOCAL_MACHINE\Snd\Event]
"EventCache"=dword:00000100
and
[HKEY_LOCAL_MACHINE\Audio\SoftwareMixer]
"BufferSize"=dword:00000200

i am aware, you probably wont find sd caches useful, but for machines with sd slot i'd advise these ones:
[HKEY_LOCAL_MACHINE\System\StorageManager\FATFS]
"CacheSize"=dword:00000040
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ TRUEFFS_DOC2\FATFS]
"CacheSize"=dword:00000040
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ TRUEFFS_DOC2\FATFS]
"DataCacheSize"=dword:00000040
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ TRUEFFS_DOC1\FATFS]
"CacheSize"=dword:00000040
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ TRUEFFS_DOC1\FATFS]
"DataCacheSize"=dword:00000040
[HKEY_LOCAL_MACHINE\System\StorageManager\Filters\f sreplxfilt]
"ReplStoreCacheSize"=dword:00000040
[HKEY_LOCAL_MACHINE\System\StorageManager\FATFS\Fil ters\fsreplxfilt]
"ReplStoreCacheSize"=dword:00000040
diamond may have SIMILAR things for internal storage, i don't know, just search for similar things, small cache usually is not slowing down ANYTHING.

revise /windows/startup
-you mean remove programs from start up?
yup. just leave what you need, and what MUST stay, throw away whole rest.

disable tick in "sounds and notifications".
-how??
heh, i do not remember that one, but it may be this:
[HKEY_LOCAL_MACHINE\Snd\Event]
"EventMask"=dword:00ffffff

avoid using upx for things that runs all the time.
dont understand..dont know what is upx..
upx packs exe and dll files to make them smaller in size, BUT if you use such file as something that works all the time, you may lose 2x more mem, it is not clear, but i think it works that way.
upx is GREAT method of rom space saving for things like word, powerpoint, that kind of things, NEVER use it to pack today plugins, etc.

reedit graphics in kitchen(even just load, and save in gfx soft may make 'em more optimzed than generic ;p)
hmm..what graphics??
take kitchen, open acdsee in oem, then sys, you will see what i mean. stupid dialer may take 50% memory less after gfx edit,.
hardcore cookers may affect res stored in dlls, execs etc.

reedit hklm/init(>71 ones are usually useless)
what keys to edit??
well, it depends on device, usually everything > than launch71 is just ...not neccesary, BUT make tests after backup on device, then affect kitchen, if succeded, or use totalcommander to evaluate things.

use optimized tsk-s.
-dont understand??
uh, you do not know what tsk's are?
tsk are today color and wallpaper themes - it may be BIG or small, optimized, or not.
here, on xdadev things like optimisation died about 2 yrs ago..you know..
cannot say more bout tsk making, i'd just say - that exactly same lookng theme may be circa about 50% smaller, than usually is(gfx optimizations, wise p/l overrides(not 4 gfxes, just 2..etc)).

ah i forgot, it is good idea to do that:

[HKEY_LOCAL_MACHINE\System\ErrorReporting\DumpSetti ngs]
"DumpEnabled"=dword:00000000
and
[HKEY_LOCAL_MACHINE\System\ErrorReporting\UploadSet tings]
"DontUpload"=dword:00000001
[HKEY_LOCAL_MACHINE\System\ErrorReporting\DumpSetti ngs]
"DumpEnabled"=dword:00000000
[HKEY_LOCAL_MACHINE\ControlPanel\Error Reporting]
"Hide"=dword:1
HKEY_LOCAL_MACHINE\ControlPanel\Customer Feedback]
"Redirect"=""
"Group"=""

one more thing:
look at different rom dumps, you will notice something interesting about fonts - there are ttf's having MUCH less size = more ram after exchange(doublecheck these - you may lose national chars in some cases, NOT always, just open ttf in any font editor to check what's inside).

one more thing:
use fake dlls for fwupdate and sqm.

sorry for poor english, good luck guys...

upd: small..reedit.
upd2: small..reedit.
upd3,4,5,6: small reedit...

[MietasSR]

BTW, manila= -10mb ram, to -12mb. Plus other htc soft, summed is a -15mb ram. Delete all this soft, or xip it! Xiped manila not work, too.

Sorry for bad english..

Idont know how large your manila package is, but mine is les than 3.5 mb :)
I will have to add some of my tips on here when I have the chance. subscibed :)

count whole related oempacks in base kitchen os....i mean everything but the core is just HTC moronic bullshit there.
and thats binded to manila.

Actually, it depends how much resources the device's dialer use. In the case of HTC Diamond, the dialer is a little bit heavy. When its disabled, frees up to 10MB. Touch PRO, HD and Diamond 2 devices may have the same results.

[utak3r]

On QVGA devices, most of the current most known dialers take around 1 up to 2MB of RAM.

[Showtime7]

You were disappointed with the RAM on the Diamond? Wow you are spoiled. Try using a Titan, then going to something like the diamond. That's over 4x what I had. <50 MB, <25 MB free on a fresh ROM. So glad I got my TP2 now. This is like salvation.

Cool as mine is 12MB inc graphics mind you my theme uncompressed is about 8MB lol
Look forward ;)

[brandonhall517]

ok cool, thanks for the explanation :)

If you open up every exe and delete all of he icons inside; and ou take al of your images and ave them for the web in PNG8 format unless yo need alpa ransparency for some; then UPXthe exe's you will have a smaller package. you can also get rid of the weather animations which will save you quite a few megabytes.. only some of the files have to be bitmaps (photo tab)

[utak3r]

then UPXthe exe's you will have a smaller package.

you have to be careful with this... and check the results after every upxing. You see, upxed binary have to be loaded to ram as a whole and there unpacked. Yes, it gives you more rom capacity - but not more ram!

Besides... if you're using lzx compression, upx is not a great deal anymore, it's doubling each over.

Hello,
Thanks for this thread, it 's very great :)

You talk about gfx edit.
Have you some informations about....

How doing good gfx optimizations ?


Thanks a lot

How doing good gfx optimizations ?


Reduce number of colors in palette, get rid of tonal gradients, which consume many colors.
Can you imagine, that in wm6.5 builds icons for G, E and so on on a taskbar are in 32bits? :eek: while they need.... 1 bit! only.

uff dint know that..so how to change this to 1bit..do you maybe have already tweaked icons?

[oldsap]

uff dint know that..so how to change this to 1bit..do you maybe have already tweaked icons?

i think it's better to use white, simple icons as colored icons eat more ram like utak3r mentioned

[joecruz]

i have a question regarding this...i have an image optimizer app that reduces the filesize of all images file while maintaining its actual size and quality, it can reduce an 800+kb file to 60kb and i dont even see any difference from the original one...now let's say i do this to all images in my kitchen and recook, will this work? i mean a kitchen has sooo many image files and this can reduce their size to more than 50% freeing up lots of space...will the functionalities get affected in the finished product?

[utak3r]

Just export the icons, the bitmaps and so on from some resource editor, edit the images and import them back into the dll.

[Nixeus]

@joecruz : Interressant, what is your soft ? I'm ok for test it :)

An other questions :

If i have some BMP in my SYS and OEM, it's better to compress it on JPG or PNG ?

Thanks a lot :)

[joecruz]

it's called image optimizer...you can use the online version but it takes a while. the full version software costs a bit but u can use it for free but it will leave a small watermark. I tried optimizing a png file with an 829kb filesize using the online version and just selecting small file size in the quality drop down and got a 60.8kb filesize back. I compared the 2 images in terms of quality and i dont see any difference, even the sizes remained the same (800x800). Here's the link http://www.imageoptimizer.net/Pages/Home.aspx

[nothin]

it's called image optimizer...

indeed, i forgot to mention this! it is useful thing, and WORKS.

[utak3r]

If i have some BMP in my SYS and OEM, it's better to compress it on JPG or PNG ?

in the terms of freeing your ram: not really. Why not? 'cause the system is loading images to the ram in the flat form, something like bmp. So - even jpegs are uncompressed in ram.

[Nixeus]

mmmm but jpeg and png are compressing with destruction, so png and jpeg have not to be decompress by windows no ?

[utak3r]

mmmm but jpeg and png are compressing with destruction, so png and jpeg have not to be decompress by windows no ?

if the image is going to be displayed, it's loaded into ram in unpacked form - bit after bit, pixel after pixel.

[Nixeus]

Thanks a lot utak3r for your reply.

So, in the SYS folder, there is some BMP.
What's the best? Staying this picture ine BMP, or saving in JPG or PNG ?

[utak3r]

you can't just change them - system won't find them!...
Just make sure they contain less data: less colors, less gradients and so on.

[Nixeus]

Ok my friend :)

I will try with image optimizer and photoshop :)

[S.V.I]

If I am correct, the image optimiszer just compresses the files making them take less space. this would work aweome for a website to help it load faster...
However, I do not think it will be helpfull to have that on a low end device. it would take time and ram to decompress the image.

The best thing I have found is to completely remove dithering from gradients. that does not mean selecting an area and blurring the crap out of it. thi means selecting an area 1pxl wide and repeating it through out the area you are trying to fill. this would remove the "flat" finish and end up making it look glossy.

basically, I performed the folowing experiment, and you can try this at home:

make an image with two colors Pinstripe.

@@@@@@@@@
------------------------
@@@@@@@@@@
------------------------
(etc)

fill a completely square area (doe not matter what size 240x240 works best. save it as an 8 bit png.

use windows preview on the desktop to duplicate and rotate the image.

You now have two files. one with pinstripes going horizontal and one vertical but same image. now look at the file size. :)

[Nixeus]

Thanks for your reply !! I will try to optimize my PNG/BMP/JPG files by Photoshop !!

A tuto will be good :D

Just an other question :

If i reversmod all my EXE and DLL in SYS and OEM.
It's good for optimize my rom ?

[oldsap]

not all modules can be recmodded. i tried recmoding the files in the OS folder and my phone didnt boot up :D

[Nixeus]

But if i reversmod all files as possible, it's better no ?

[utak3r]

But if i reversmod all files as possible, it's better no ?

Yes, it's much better - but you should do it a package after package - SOME files won't run after modularization... Fortunately, it happens rarely.

The other problem is the limit of modules addressing space: it would be better if you would have wm6.5 nk.exe.

[Nixeus]

Yes i understand !
Unfortunately, there is no wm6.5 nk.exe for ELF/ELFIN :-(

Very good idea to collect this, bro!
Can you also WIKI it?

Thanks.

[Nixeus]

[ thread error ] sorry

[Nixeus]

OO Yes, this thread is a very good idea !
It will be good to having a little tutorial in order to do GFX optimizations ! :)

Thanks a lot :)

[apaquette420]

one of the best ways that i have found to remove files that are in the rom and cant be deleted, i open notepad and make 0k dummy files of the file i wont gone and then overwrite it where ever it is and bam you gain that space back that was wasted on dumn stuff you dont need !!! just my 2 cents!!

[Nixeus]

you can't just change them - system won't find them!...
Just make sure they contain less data: less colors, less gradients and so on.

Will be it possible to have a little tutorial in order to optimize the gfx ?

Thanks a lot :)

[S.V.I]

quick tutorial on optimizing gfx (sorry no time for a long one)

open the png in photoshop and save for web using 8 bit format. select as few colors as it pleases the eye. click save.

if you need alpha transparency (like glass) open the new 8bit png that you created and convert it back to RGB.
then duplicate the layer and hide the background layer. make the new layer as transparent a you want, then save the file as 24bit png (with the save for web) make sure the box for transparency is checked. click save.

you now have smaller files than before.

i you need to edit a gif file the same way, open it save for web a png then rename the extension back to gif.

the trick to optimizing gfx is making a low rez image from scratch and being creative enough to make it look good. or just using the old image as a template to build a new one.

[Nixeus]

Thanks for your fast answer !!!

I have seen the BMP inb the shell folder ( E, 3G...etc....) and it appear that these bMP are in 1bit, so i think that we cannot optimize these picture :(

[farukb]

a quickie...what tool do you use to export those dlls...

and does anyone know why nothin got banned

For PNGs you can use PNGGountlet in addition. This tool makes the graphic files even smaller too.

[utak3r]

Why the sadness?? It's the most optimized image one can ever see... what would you want to optimize in it? :rolleyes:

yeah, I said it... but YOU said those bitmaps are... of 1-bit color depth, so... they're already optimized :cool:

[S.V.I]

I dont think it will help me. I already build gfx from scratch. besides, I dont want to undo all o that work by wasting the cpu time to decompress the images. it really isnt the size that counts, but how predictable the pixel structure is.

[utak3r]

Exactly so.

I can see most of you still don't understand one thing: file size has nothing to do with the speed or RAM usage! I've said it once already, I'll repeat: every image, no matter how it was saved, when loaded into RAM for displaying on your screen, takes bits_per_pixel x width x height bytes! So for the RAM usage everything you can do is to reduce color pallete. And for the speed of the app you can make sure the image is decompressing fast - and that means no heavy compressed files!

All those tools mentioned here have completely different audience than we are here - they're for optimizing file size for putting into the website.

[Nixeus]

OK, thanks a lot for your informations !
In all the cases, the bmp in 24bits must be reducing in 16bits no ?
Because our screen are in 16bits ? true ?

[Nixeus]

I have found this tool which can optimize bmp,png..etc

It can reduce color...etc......


http://www.4neurons.com/other/mbm/mbm.html

[utak3r]

In all the cases, the bmp in 24bits must be reducing in 16bits no ?
Because our screen are in 16bits ? true ?

not the screens - but Windows Mobile itself doesn't support 24b depth of colors... which is pathetic.
The key is to operate on good image editor, which is able to present you the image while you're degrading its palette :) Some images look pretty much the same with only 8 bits per pixel :) and even less (all the icons and so on).

[mrrouge]

Very good thread.

can you provide a cab for a optimized taskbar?

thanks!

[dertnberny]

Go to 'HKEY_LOCAL_MACHINE/Security/Phone/Skin' and change the value of 'Enabled' from 1 to 0.

Ok I am a Noob. How do you do this? Find it on your phone.

[Farmer Ted]

Ok I am a Noob. How do you do this? Find it on your phone.

Get total commander, click plugins-registry-hklm-...until you get to the value. Click it, change to 0, click ok and soft reset.

Do a backup beforehand, in case you pull a boneheaded move and delete half your registry. :p

Thanks. Im still lost tho. so much crap in registry/hklm

*edit* Nevermind, I got it. Thanks to everyone in this thread

[benko286]

I love this myBitmap.exe..I reduced some pictures more than a half!!

But one thing I hate..optimizing is so slow!!
I need to open every image, reduce colors, reduce bits and than save it..

Can I somehow select 50pics set parameters to reduce colors to 128 colors and reduce color depht to 8bit..So that optimizing goes faster?

EDIT:fixed a problem

[Vapaus00]

Opera has reserved 60 MB of HTC Diamond's ram ( I don't know for others ) If we could remove that it would mean a huge plus.Anyone knows how?

[Vapaus00]

Sorry for posting it again. My mistake.

[ishan.arora]

done..read the previous post..will check if the ram usage shoots up again...

[pigreca]

great job!!
