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.
The specs in the HTC Dream list 192MB of ram and 256MB of rom. I have about 30MB of free ram..
So is android 2.1 really using the entire 162MB of ram?
Thanks

lol ^^
ps i think g1 only has like 70mb (user available) the most i ever had free was between 50-60mb not sure what the limit is though... im sure its on here somewhere..
most of the time i only have 10mb free ram
This question is lame.
First off, with the right radio/spl combination, there is over 100 MB of RAM available for Android/Linux. The balance is allocated to the GPU/media, and RADIO PROCESSOR.
Free memory on Android is MEANINGLESS. It has an intelligent process killer. Based on process priorities, when there is insufficient RAM to run the software you are trying to run, it will kill off low priority processes to free up what you need. The correct behavior is for Android to keep everything running/loaded until the memory is needed for other processes, at which point it will kill low priority ones to make room.
As I previously read, out of the 512 MB of our O2X's, some 128-140 MB are reserved for the Tegra chip-set, and the rest of 380 MB are available to Android and applications.
With Froyo, there were usually 180-200 MB of memory free after booting/killing all apps, and like 90-130 MB free after normal usage. I'm not sure, but if I remember correctly, in the running apps screen, the sum of the used/available memory summed up to about the previous stated 380 MB.
After applying the GB update, after booting/killing all apps there are only 140 MB free and about 60 MB after some usage. If I go to Manage Apps -> Running apps, the sum of the used and available memory is around 310-320.
My question is: why is there less memory available in GB? Has LG increased the graphics memory from 128 MB to 192 MB? If yes, is it possible to change this allocation? Or is there a ROM that uses less graphics memory?
Maybe GB reports available memory differently, but it's definitely noticeable that there's less RAM available. If switching from browser to another app, with Froyo the page loaded was kept in memory, however with GB the page always has to be reloaded even if the switch lasted like 20-30 seconds.
Edit: I'd like to use less graphics memory and have more RAM so my apps run faster.
No the Vram is the same. The phone still has 380 mb ram to use for the OS and apps. Also free ram is wasted ram since apps are not cached so they will not launch faster.

And therefore taskplanners are also not needed ;-)

Not completely true. Android kills automatically unneeded processes, that's true, but sometimes it happens that an app remains in background and uses the 100% of the CPU, so i use the task killers to terminate it.
Try Super charger, very efficient and not as resources consuming than apps. Search the dedicated thread.
And I don't think there is a way to free graphical memory. I don't think it's software driven but physical...
The only thing that had been made is to free the reserved memory for OTA LG service, that leaves you some more memory, but only available in some roms.

Its possible to give the GPU less memory, different defs have done it (i.e benee). But as far as i know most of them removed that tweak since it was causing alot of bugs.
And yes, free ram are most likely wasted ram.

If ya want to change vram look at this: https://raw.github.com/gist/1170959/73e5f41b1ad8b3bb65c8bd22d422a4fd877204a3/CarveoutMemory
It contains a little info about the things you need to change. Some skills required though

Hi kiljacken !
I remember that you've made some times ago a kernel with 64mb more of ram...
Also for the stock rom...
butI can't find it anymore...
Any help?
Thanks for the replies guys!
It seems like if possible, it's very complicated to change the video memory allocation, so I'll leave it like that.
hey all!
i have question like that! im working on electronic factory and have no problems with solder out and in BGA chips even the smallest ones! now the question! if i will solder out the ram chip and solder back in 1GB ram chip of the same tipe and company(i have acces to all the part available on the market)?

How small is the solder required? Would be amazing if we could upgrade.

I'm very unsure. I am sure though, that both kernel and boot image changes would be needed to run with the added memory
i think it's impposible to change the graphic memory size, maybe RAM hack? if you want to free RAM just use supercharger, i already used that and my free ram about 117-130 MB
It's completely possible, it's something that's controlled by the kernel.
Such kernels already were in the spring which reduced video memory by 64 Mb

so if I'm understanding correct if i will solder in new memory chip all i will need is to find how to change the ram value from 372 to 872?

I suppose if LG's programmers were careful enough not to hard-code any values, the phone should detect the memory like a computer detects new RAM. However ROMs which target multiple devices with different RAM, like CM, shouldn't have such issues...
I would LOVE 1GB ram! What would such ram cost?
Guys, RAM amounts are hardcoded into the kernel, so a custom kernel would be needed to use the ram. IF it's even possible to use such amounts of RAM. There migth be limitations in the bootloader, which will cause problems, but kernel changes should be enough. If you try it on your device I would be glad to provide a kernel that supports that amount of RAM, but I don't think it's doable. AFAIK the RAM is tightly packed in the device with many other components. It might even be built into the SoC making it impossible to change. But IDK, feel free to try what you want, but remember it's your device that gets destroyed if something goes wrong.
Do it OP!

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.
Your OS doesn't need RAM to function right?

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.
