576mb ram vs 512mb ram

Is there a massive diiference in performance between a phone with 576 mb ram e.g htc desire and a phone with 512mb ram eg. the google nexus one?
thanks

The only difference is that you get 64MB more RAM to hold a handful more applications in the background. The performance difference is only going to be appreciable if the applications that are being let go in that 64MB "buffer" take a long time to load up.

I've read before that they are identical, just reported differently.
512Mb RAM + 64Mb baseband.
Pretty sure I read it on here, but could be wrong.

Dont matter as the current kernels wont see more than appox 400 MB

+1, and it's written in many places.

Yeah, the Desire doesn't have any more memory than the Nexus One. They just report it differently.

[Q] Galaxy S RAM ? Not 512mb?

Hello, both quadrant and setcpu show me 334Mb total RAM and 85mb free... quadrant also shows me 143Mb inactive RAM
wth?

This will be updated in 2.2FROYO where all 512MB RAM will be available for use.

Hopefully you are right, any source where i can see the official statement about this issue?

From another thread:
Sigh. No. No ROM ever will. This is because the radio firmware reserves a lump of RAM all to itself so that you can... you know... make and receive calls.
Can you imagine how annoyed you would be if you missed calls or SMSes just because you'd used up all the available memory?

As said in more threads sgs has 512 mb but you loose ram for kernel, shared memory and phone memory. At the end you have about 300 MB of available memory on stock kernel. So samsung doesn't lies.
Ciao Angelo

Omg is this thread for real? Someone delete it ffs.

Link to where it is said as a 384MB device, coz currently we only have 350+ max usable but its unstable but the device functions wll at 340MB usable.
I wonder how the guys with the N1 reacted since they only see 192MB of their 512MB ram

Where do they market as less than 512? And I hope that you are not using the Verizon picture as a basis to your reasoning.

N1 only saw ~200MB of RAM because a bug in Linux kernel. With the bug corrected you see 512MB of TOTAL RAM.
And yes, N1 owners complained about this. The difference is that there was a lot less fanboys defending Google or HTC about this matter.

Even the Tab has 444MB
http://www.gsmarena.com/samsung_p1000_galaxy_tab-review-527p3.php
or
youtube.com/watch?v=EMLJOa2KFK0&feature=player_embedded
at the 37th second you'll see 444MB total while they advertize with "Internal 16/32 GB storage, 512 MB RAM"
and such a tab is even more expensive then a sgs.. =/

I'm 99% sure that's wrong. It wasn't a bug, it just didn't support larger amounts which was because of the way ARM was designed apparently. Linux was designed that way, and needed to be updated.
This is a totally different situation, and not sure why billboa is claiming that samsung now markets the SGS as 384mb of ram either. I have seen NO evidence of that, and if that's true, please show proof the SGS is being marketed as 384mb.
I agree that we do need more spare RAM to be available (especially in the froyo leaks, which may be betas anyway) and the currently-reserved RAM to be allocated dynamically when needed, so there is more ram available at other times. RAM allocation is cheap afterall.

You mean the link in this thread? Because those point to custom models. Just because one Xbox includes a HDD for instance, doesn't mean all models do. I'm still having serious trouble finding any evidence that Samsung are advertising the international unit as 384MB of RAM..

Is this based on theory or actual experience, because on the N1 that Im holding right now shows only x/192MB and its 2.2.1

Well, maybe it's not a N1 you are holding? What about a screenshot?
I can show you a picture of two devices side by side: N1 (FRG83) showing 390MB and i9000 (FROYO.JHJP8) with only 304MB.

I have a Galaxy S model GT-I9000B ( brazilian version from VIVO carrier )
I flashed froyo BVJJPD and my ram manager says I have only 304 MB RAM.
weird.

Sigh
The galaxy s actual does have 512mb of RAM inside it. Out of that 512mb, 128mb is used by the gpu or something involving the hardware(I don't really know where so not going to pretend I do). Then out of the remaining 384mb some is used by the system. I say some cos different kernels use a different amount.
Like on damiangtos 2.2 kernel there was 360mb of ram free at one point.

important question

on the specs, it says GS1 has 512mb of RAM. I know android OS takes space phone it self blah blah so we only get to use 3xx mb of RAM. but then usually half (if not more) of the 3xx mb of RAM is already filled!
before, (back in eclair & froyo days) android 2.3 will allow us to utilize ALL 512mb but ****, now even more RAM is in use..
also
someone told me Nexus S who has exact same specs as GS, can use ALL 512mb...
so is there a way to use all 512mb of RAM? or at least more than 329mb?

You do use all the RAM, Android users shouldn't be worried about RAM as it is good to be used... Now Samsung's excuse for updating the GS1 to ICS is bull. but the reason you get 329 MB of RAM is because that 183 MB of RAM is for the system and cannot be given to the user. There are some kernels that offer like 344 MB of RAM(for Froyo), but that is it. No more, no less. Can't change it! Sorry bud.
Edit- we always are utilizing all 512 MB of RAM always. And when half of it is filled, that is always going to be there if the phone is turned on as some none system apps and system apps cannot be closed and are needed for the device to function.

I just recently got myself a Samsung Infuse, really like the phone. One thing that really bugs me is that it appears to be the same as my captivate in terms of RAM and ROM space, yet on my Infuse i get access to 452MB RAM yet on my captivate as stated we only get access to 329MB or 344MB.
Why such the huge difference?

[Q] Ramdom Access Memory

Hello running Teamhacksung ICS 15 with ICY GLITCH v14-
I need some help understanding this....I have 2 gb internal storage? 13.03 gb USB storage? 4 gb external micro-sd card? I have 1.85 available Internal 11.74 USB ...all that being said...why is my memory being so taxed? please see attached screenshot

The Captivate has 512 MB of RAM, 16GB of NAND flash memory (partitioned for different parts of the OS), and you have a 4 GB NAND flash Micro SD card.
RAM is different from flash memory or a hard disk. RAM is what your phone uses to run software and hold temporary data for quick access.

Lol because our phones ram sucks.... at best i get ~ 125MB free ram. I avg 40-80 MB with all my widgets and a few apps open.
Edit: that 512MB is a lie... THE CAKE IS A LIE! lol

But thats with all apps running at startup? If you have less apps running shouldnt you have less stress on RAM? Man it sucks someone hasnt developed an app similar to readyboost in I HATE WINDOWS...doesnt it use flash memory as ram? Ok...so with reference to my screenshot my memory usage is normal?

Why do you want free RAM? If it's unused, it's wasted. Another tidbit that no one seems to ever mention is that resources in Android are memory-mapped. If things like images and other binary objects are aligned properly, they will not be copied into RAM at runtime, but read directly from their stored location.

This is true. But android doesn't always manage its memory perfectly. I usually close apps out of habit, but if I let it I can have alot of apps open and I won't notice. Then again I've been using since 2.1 and that REALLY sucked with memory management.

True. 340MB is free for user space. The rest is for kernel, video, audio buffers, etc.

340MB(Galaxyian) is on big MEM kernels(truly 344MB on others, but he found a way to keep HD recording!) On any stock ROM's it is 329MB available...

Image above says he has closer to 355mb

LOL. That's because 1MB = 1048576 bytes, so 340 x 1MB = 356,515,840
TalenDEV bigmen is 352MB, but no HD recording and I think it messed up HD playback as well. I don't worry about it too much.

I know, was pulling your chain

[Q] is there really 2 gb of memory in this phone?

Hi,
I'm a bit surprised that if I add free memory and used memory from the Settings app the total is about 1.7 gb. Ain't we supposed to get 2gb? I hope sony didn't do the hdd trick (see wikipedia page on Kibibyte, I cannot post link as a junior member) and even so 2000000/1048576 = 1.907 ... where's my ram?

Under CPU-Z that show : 1.732Mb.

yes it does but I thought it will be included in the "used memory"... if the OS takes 300 mb that's ok but why I only got 900 mb free when I kill all apps? I used to have a nexus 4 and with the same amount of memory on chip there was a *LOT* more available in the settings menu.

That 900MB figure is about the same I normally have free. Various apps and services take up about 800MB on my phone, which seems excessive but I've turned off all background stuff that I can (some Google and Xperia services just won't go away, however). The only good news is that Android will free up memory if it's needed so that 900MB is not a finite figure (at least that's what I assume).

Hmm. I generally have no more than about 300 mb free memory at any given moment. Even just a few minutes after reboot. No weird apps or excessive widgets. Do you guys really have 900 mb free? You can check your memory on the fly using Cool Tool from Google Play.

The Z3C has 2GB of RAM, don't worry. What you are missing is used by shared graphics memory. BTW: This is exactly the reason why the Z3 has 3GB of memory (instead of 2GB) for its screen resolution is full HD opposed to "only" HD on the Z3C.
Anyhow, is it really necessary to start another thread on the same topic if there already is one?

I have never had any doubts about the two gigs. But how much free memory do you have on your Z3C after a reboot and after a few hours of typical usage? My other phones with this much ram have generally had a lot more memory available at any given moment. Not that *free* memory is of any particular use in android, but I'm still curious to see whether your Z3C's are the same.

When I boot up the phone and immediatly check it shows some 800MB of free memory. About 500 to 600MB after a couple of days, fluctuating though. However, don't think these numbers have any meaning for Android keeps as much in memory as possible in order to increase responsiveness. It also depends on the Apps installed and the bloat disabled/blocked. Further, comparing it to other phones you had earlier might also be misleading since the version of Android could be a different one, hence comparing apples to apples would just not be possible.
