Develop Bugs

[Q to devs and everyone]what is the max RAM amount we can get from galaxy s?

i have started my own and read every topic about why we could not see all the ram as user available (329 instead of 512) .. first i compared galaxy s with tab but it turned out tab has 640 Mb of real memory in total.. but i also have seen it was possible to add more memory about 40 Mb to the user available ram .. and i also learned there is also a part which is not used and called "blackhole" approximitely another 40 Mb..
so i believe it is possible to make some adjustments to improve the weakest (according to me) part of our galaxy s.. would some devs please mind trying this for us and share it?

We don't need the RAM (yet)
There are a lot of developers who try to get more out of our SGS's. For instance Juwe/ GingerReal increases the RAM to around 340MB.
Appearently Google thinks we don't need the full potential RAM and that's why they made it with a default of 300-330MB. Still still most developers agree on XDA that we should be able to acces the other 160MB because it doesn't do anything.
Until then we'll just have to wait.

even 340 Mb instead of 329 makes a difference .. i cant think what would happen with 380 or 400 or maybe even more..
because as far as i understood from what i have read; 128 memory is reserved for some drivers and capturing video is taking most of it.. i am taking a video maybe once in 2 monts.. but i am using my widgets, apps, playing my games everyday.. so if was asked to choose i would love to have that memory reserved for video taking..
edit:typo

First of all, the amount of RAM is NOT related to the ROM....
The kernel makes the difference...
In general the max amount of RAM in Gingerbread is 340MB, cuz if we go over the phone will become unstable and we'll break some functions like 720p recording....
In Froyo we used to reach max of 350MB without issues

just curiosity;
galaxy s2 and galaxy s has the same rams with different amounts.. what would happen if we soldered the 1gb ram to galaxy s? would it recognize it without any software tuning? or would we just kill the phone completely? or would still see 329 ?

so is it possible to disable video recording completely and having lots of more Mb?

Do you want to instert 1GB ram into our SGS? I dunno sincerely what will happen.....

Probably yes, i am not a kernel expert, i am only a rom cooker/recognised developer, so my knowledge on kernels is very basic....
Maybe you'd better directly ask to a kernel dev like hardcore, nikademus, chainfire....

i would really want that but i am sure its not as easy as soldering the gps antenna.. i have read about a HTC device getting a memory upgrade to 128Mb from 64 in xda forum.. so technically there is no impossible but i wonder what else need to be done after soldering the ram? software adjustments (kernel maybe?), or any more hardware changes ?

thanks for tip, i will ask them..

i am really feeling bad about this ram issue.. every web page is showing nexus, galaxy s, galaxy tab have 512 Mb of ram.. but the memory dedicated for users is far less than the other 2 phones in galaxy s ... so it bothers me.. is there anyone who returns their phones to samsung and gets the money back?
first i believed somehow it was possible to use most of the ram with some software adjustement but then i realised even quadrant shows the total amount of ram memory is only 384 mb (and there is a part which is not used at all) ..

V6 Supercharger

I am an Eris user, soon to be DINC2 owner at the end of this week. I've been reading through the threads here getting ready for my purchase and it has been very informative.
I searched the DINC2 forums and did not see this mentioned. Has anyone tried zepplinrox' V6 Supercharger script on the DINC2? I'm not going to regurgitate his post verbatim, but it is a memory optimizer. It was introduced to me over on the Eris forums, in the GSB ROM thread. It really makes a difference on the Eris, but I'm not sure how much difference it would make on the DINC2.
http://forum.xda-developers.com/showthread.php?t=991276
He also has another script called 3G Turbocharger. This will probably make a difference on the DINC2. According to zepplinrox, "the 3g script reconfigures the build.prob and kernel to change the speed settings to a better enhanced setting. Think of it like a TCP optimizer on windows." On my phone I have noticed an increase in speed surfing the web, downloading apps and in other 3g activities. It may be placebo, but it does seem faster. If nothing else, I do plan to add this to my DINC2 when I get it.
http://forum.xda-developers.com/showthread.php?p=15948434#post15948434
There is also a Kernel Tweaks script on the above link as well. I am using it too, but not sure what performance gains I am getting.
Per zepplinrox' post, this should work on stock and rooted ROMS.
I am by no means an expert on this, so don't shoot me if this is in the wrong forum, not valid on the DINC2, or a repost. Just trying to pass along something that works well for me.

For now those scripts are useless for phone that came preloaded with GB 2.3.3.....no root no turbo.

This sounds interesting to me, I am rooted, would it work?

This wouldn't really benefit the Inc2. The Eris was a very memory limited device designed to run Android 1.5. Upgrading beyond this was pushing the Eris to its limits, and in some cases, beyond. Running newer versions of Android would make memory management more difficult because of the higher memory requirements and the very limited memory.
The Inc2 has one of the bigger pools of memory available for Android devices. It has 768mb of total RAM when many current generation devices are getting 512mb (others are either getting 768mb or 1gb). Unless you are running a LOT of background apps, or somehow managed to find apps that require massive amounts of memory, this is plenty of room.
What does it do? It tunes memory settings and task manager. That's pretty much it. It could have an effect on the Inc2, but I wouldn't really consider it a necessity.
Edit: BTW, my previous device was an Eris.

Well, Desire HD users with 768mb of ram enjoy improvements.
It even improves performance of an Atrix with 1gb or ram...
So it probably will help.
So "It tunes memory settings and task manager" is an understatement.
It revamps the whole memory thing

Actually, I think these will work without root. I think the only drawback without root is the scripts do not stick on boot so you have to re-run on each boot/reboot.

It may not, but zepplinrox posted above about the Desire HD with similar RAM and the Atrix with more that reported improvements.
Whether you use the Supercharger script or not, the 3G Turbo is definitely worth trying. Again, it may be placebo, but I think my up/download speeds are faster after the script. Here is a post with some info on speed improvements with the script.
http://forum.xda-developers.com/showpost.php?p=15959134&postcount=1139

I use the Mega memory option with the v6 script. I notice a huge difference in performance.

same here. i've actually tried the v6 superchgarer and saw no improvements. actually, the only thing that happened was my battery life took a hit.

lol, well that's no good.

How to make more RAM available to the user?

Hello @ all,
as you might know we have only 343MB of RAM available to the user on our Arcs, but we have a total of 512MB RAM.
I did some research and found out that the most phones with 512MB RAM have 370-400MB or even more RAM out of the 512MB available to the user.
I know that there is something reserved for the system, but normally it's less.
But sometimes I'd really like to have a few MB more RAM available when I do multitasking or a lot of stuff is running.
So the question is if we can unlock more RAM for us and an even better user experience? And if yes, how to do it.
Regards,
Flo

May be a mix from a swap partition and the supercharger script is the right for you
The supercharge script optimize the memory management of android

Already have SuperCharger V6 installed.
Does a really great job and fixed the problem with LauncherPro Plus redrawing often.
But still I'd like to have more RAM available...
For example the X10 with 384MB has ~280MB available, so we should have ~410MB available on the Arc. And not just 60MB more...

No you can not unlock the RAM or ROM for further use, you however can optimize it by using external scripts and the reason for 343 megs being available is because around 150-170(approx) megs of RAM is being used by the graphics (GPU).... u did not account for that now did u... . Now maybe just maybe u can use a custom made kernel to squeeze some more juice out of the RAM...but no major RAM increase

Ah, okay.
But somehow it's possible.
Today I saw a review of a custom ROM on youtube for an Evo 3D...
And other phones with the same GPU have less memory reserved.
E.g. Desire HD, Desire Z
Strange that SE reserves that much

Your phone reserves memory for hardware, camera for example. It works the same way as reserved memory for integrated graphics on computers. We have HD recording in the arc now that has to come from somewhere, and just where would that place be?........the RAM. SE has tried very hard to squeeze in some very good features into the arc and that's why I guess they made a trade off with the RAM, and all these features require RAM and its not a luxury that SE has to reserve all that RAM but a necessity so we users can enjoy some great HD recording and amazing resolution.
One more thing even though the Desire HD and Xperia Arc do share the same processor (MSM8255 SnapDragon) the HTC Desire HD has 768 MB RAM and 1.5 GB of internal flash memory data storage and the Desire Z on the other hand uses a MSM7230 SnapDragon even though the GPU is the same the processors differ the MSM8255 is 1GHz and the MSM7230 is 800MHZ and in the overall equation of memory reserving other than the GPU the CPU has its part to play too and a very imp one...hope ur getting the idea and the GPU in the MSM8255 is a marked improvement over the GPU the 'Z' has. Now even though HD does have lesser memory reserved its not that big a difference. However on the arc, the camera is way much better than on the HD (camera-->RAM) so SE has used some more memory for better features.

I think everybody want to have more ram and more ram
but only thing that we can do is tweaking our system again and again.
I´am for example using the supercharger v6 option 4 and a swap partition and its great to see some improfment
I am looking for tweaks all the days but i am not so good in android so it need time

Ok, then.
If it has to be like that...
Just want to get the optimum out of my Arc.
Maybe a dev will come with a kernel that unlocks just a little bit more with keeping all the features

[Q] Gaming on ICS, RAM and other performance questions

Do you guys know why is gaming so bad on ICS? I have arconium 2.1a rom right now, but even with different versions of ICS, all "HD" games crash or terribly lag. What is the problem? Isn't ICS supposed to have newer gpu driver that increases performance? Or am I simply always using bad ROMS?
I am suspecting the problem is with the amount of free RAM, so here is my another question:
Xperia arc has 512MB ram. Some of it is reserved by system, and about 300MB should remain for the user. Where is this 300MB? The maximum free RAM, even in the lightest roms after killing everything, is 180MB. How is this possible?
Thanks for answers!

My XMD become too slow need help

Hi all
My Xperia m dual become too slow sometime in such way that I can't even text properly and it become normal when I restart my phone
Why it is happening so
Is there any alternative solution except restarting??:banghead:

This is something to do with RAM. The longer you used your phone, the more RAM is consumed. Now don't blame Sony for bad RAM management, all Android kinda suffer the same... except higher ends have more RAM which helps those phone snappy.
IPhone on the other hand can literally outperform 2 or 3GB RAM Android smartphone, why? It's because Android chose to use a 'garbage collection' solution for memory management. Well it's not something bad if you have enough free RAM and is actually quite an efficient memory solution, but as the RAM usage increases, the performance drops dramatically and thus explains you're Xperia M to lag. IPhone uses another solution for memory management which is far more efficient as compared to Android's. There's more info found here : http://www.phonearena.com/news/Why-...and-iOS-gets-by-with-1GB-of-the-stuff_id62901
Hopefully you are rooted, so I suggest this apps to you: Greenify( https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=en ) and this RAM booster ( https://play.google.com/store/apps/details?id=com.rootuninstaller.rambooster )
