[Q] Locked RAM - is it possible to unlock? - GT540 Optimus General

Hey there!
I've read, that the gt540 comes with 256mb ram, but you can only access ~160mb on stock roms. Is there any way I can unlock the remaining ram without installing a custom rom? (I have the 2.1 stock rom) Thanks for any replies

Sorry, It only has 128MB of RAM.

That's wrong. It has 256mb. You can only access 160mb, because the rest is used by system I think.

Actually, I was wrong, it has 158 MB of RAM. and 139 is available to user.

If it had 256mb ram
LG Would of Released Android 2.2 if the GT540 had 256mb of ram. Proof, LG Optimus One

Our phone has 256mb of ram, but we are able to use only 160 beacose the rest of it goes to video chip for rendering. In lg optimus one video chip have his own ram.

It does not have 256MB of RAM, otherwise we would have well over 100MB of free memory w/o odexing 2.2.

Lear to read system can use only 160 beacose rest is reserved for graphic and other components. You will never see this ram. In our phone memory chip is 256MB and that is a fact.

its possible to hack into the system and change the amount of MB's. but it can only add like 5 mb, and i am not gonna spend my time hacking my hardware to add 5 mb

Actually, there is no way to physically hack the RAM to give you more, it's just not possible. Although it is possible to add virtual memory, but this will kill your phones Internal NAND Memory or SDCard quicker as the read/write cycles will increase dramatically.

Quick question about Android RAM...

I saw that the Nexus has 512 megs of ram which on plenty to run apps. I like the X10 overall better for the 8mpx camera, but it has only 256 for ram. Is this gonna be an issues for the x10? My friend who has a Magic said that there is a way to increase the ram by doing virtua memory on the SD card...You think it will work well on the X10 1gb internal storage? How well does the apps run on SD card?
SW Swap is realllllllllllly slow compared to realy memory. I think 256mb will be plenty for running apps.

But the Hero has 288 and its older than the sony phone.
Legends say the andro OS itself uses up 150~ MB of ram for the Phone in question(Dream,Magic,Hero,Behold,etc)
There is a suggestion that the final hardware revision will actually have increased RAM and it's the prototypes which are still on 256MB. We can only wait and see how accurate this is though
Ram: 256MB
The Acer Liquid only has 256MB Ram and it is very fast - no issues at all.
It all depends on how many services you wanna run at the same time...
I run 25/30 services all the time and have no complains in my hero....though mem avayable is only 30mg....you can always keep killing services with advance task killer.Only 2 clicks in 3 seconds....as easy as that
Android automatically kills idle processes when ram usage shoots up anyway

Galaxy S Ram and Himem........

Hi all,
I am getting this phone on July 21 when it's avaible through T-mobile. However, I ran across an issue while reading on the vast number of threads about this phone regarding the available memory.
1. Is it true the Android 2.1 is limited to 256mb of ram unless "hi-mem" is installed/enabled by the rom?
2. Is hi-mem enabled on the SGS stock rom? From my reading it doesn't appear that it's properly enabled.
3. If hi-mem isn't enabled, does that mean the SGS is functioning with only 1/2 of it's ram?
4. If so, how much free ram is showing on the stock rom and how much should we see once hi-mem is enabled?
I'm assuming that since many Android phones come with 512mb of ram these days, that hi-mem has been properly enabled on some of them. How much free ram does a typical android phone running 2.1 or 2.2 have after bootup?
I'm currently using a Touch Pro 2 which runs out memory all the time and would rather not have to deal with that on Android as well. I assumed that 512mb is supposedly to be more than enough to run 10+ programs at the same time should I choose to.
Thanks in advance.
It doesn't appear to be using 512MB I only ever have around 100 meg free. I used to have a touch hd and know what you must be thinking but i can assure you even with only 256 available it is fast and hasn't run out of memory on me yet. be sure to download a memory freeing app like task killer.
It runs quake3, something i could never get my hd to do with out practically killing the os
Kernel supports 512M RAM.
with the new Gingerbread specs it REQUIRES 512MB .. now if its 256MB , that's something to worry about

Don't worry, it has 512mb. It's just that some older kernels didn't support more than 256mb of ram, so the phone simply didn't "see" all 512mb.
My concern was that the kernel out of the box was too old to support the full amount.
The phone physically has 512MB of RAM. However, I think Android 2.1 is limiting the availability to 256MB.
Froyo 2.2 will correct this issue.

326MB of RAM?

Just got a Samsung Vibrant.
I noticed the phone says I only have 326MB of total RAM. I thought this phone was suppose to have 512MB of RAM? Is 326MB normal or did I get an odd phone?
No that's right. It's all the kernel will allow us to use. Even with the unofficial froyo roms out, we only get 341mb.
Friends don't let friends flash drunk...
Cool. Thank you for the information.

It's also strange that hard drive manufacturers advertise a "500GB" hard drive when you really only get about 465GB of actual usable space.
Same concept. Froyo may be able to utilize more RAM than Eclair but you'll never get the full "512MB"

I would say it is more like on your PC. You may have 4 GB installed, but when you look at it it will tell you you have only access to 3.5 GB because other hardware is using the memory, like a shared GPU etc.

I'm getting tired of people making these retarded f****ng comparisons. Hard Drive capacities go down due to formating. Also, a 1 byte file takes up the smallest allocation unit on the drive, so space is wasted there as well. Better file systems are better about it, but unless you're writing raw data to the hard drive there's no way to avoid formatting it and losing space or writing data to it and losing space due to allocation boundaries. I've never heard of anyone Formatting RAM, have you? If the smallest allocation unit on the HDD is 4KB, then a 1Byte file will really take up 4KB on the drive's FS.
RAM is totally different. If there is 512 RAM there's 512 RAM. The only time you will see less than your amount of RAM on a computer is if the computer is allocatting a certain amount of RAM for use by an integrated graphics card (or something else).
Problem with our phones is that they're set up like the latter.
We don't have 512 RAM. We never have, and we never will. We haev 340'ish and the rest is GPU RAM. You're never going to run general applications on that RAM.
Oh. I had edited my reply because I had assumed I found my answer from this...
developer.android.com/sdk/android-2.2-highlights.html
"HIGHMEM support for RAM >256MB"
I had assumed that mean the official Froyo when we got it would have 512MB available.
So I guess I misunderstood their meaning there. So the 326MB is pretty much the max my applications will have to work with on this phone?
I guess I'm puzzled because I was in T-Mobile a couple days ago and I was going back and forth between getting this Vibrant and the MyTouch 4G. The MyTouch 4G advertises 768MB of RAM, while the Vibrant advertises 512MB of RAM.
So now I'm back to my original confusion. Why would HTC put 768MB of RAM in the MyTouch 4G if Android can't even use 512MB? *confused*
Ya'll compared it to the Windows XP limitation with only seeing 3.2-ish GB of RAM. But Dell doesn't install 8GB of RAM in Windows XP computers either. I guess I could maybe understand the 512MB phones if some of the memory is going towards video. But the 768MB phone doesn't make sense then.
This is my first Android device, so I'm still trying to figure out these things. Sorry for the dumb questions.

First of all. There are no dumb question. Second. Android uses all of the RAM. But as the phone reserves memory for hardware and other system essential services, you will only be able to use a certain amount of the memory. In this case around 345 out of the 512. The rest is put away so that the OS can run stable etc.
So for the MyTouch 4G it says that there is 768 MB installed, but you won't see all of that. The phone will reserve certain amount for it's hardware and you will never be able to free it unless you know how to change the kernel.
Hope this clears any confusion up.

for xp, the memory limitation is due to 32bit memory addressing. 32bits can address a theoretical 4gb, however due to also addressing gpu memory and probably some other reasons xp can't address the entire 4gb and so you see 3.xGB.
i can't really speak to android or the vibrant, but i'm guessing (like others have said) we are losing some of our ram in a share with the gpu.
I think most people are missing the issue here.
The phones are advertised as having 512 MB RAM.
When you buy a computer, and it says 512, it comes with 512 (only exception is the one I stated - integrated graphics cards sharing system RAM - but that is usually listed on the Computer Spec sheet).
So, when they get a phone and it says 512 MB RAM, they expect for there to be 512 Application-accessible RAM on the device.
HTC adds more RAM to put the user closer to the advertised specs. Most other manufacturers do not.
So users end up with 326 MB RAM wondering if they got what they paid for.
Which... they really didn't if you use you common sense, but companies will always use technicalities tand semantics o defend their decisions and/or actions.

I completely agree with you. In fact some of us in xda have discovered that sgs indeed has less than 512MB of RAM. We are still somehow trying to defend Samsung by say Galaxy TAB has more RAM (when Samsung advertise 512MB only for TAB)!
On a side note - Hard Drive capacity is measured in millions of bytes hence 500,000millionbytes
will be around 465GB only (unformated)!

I doubt ~170 mb is being allocated for the radio and for hardware addressing space. It's my opinion that the phone actually only comes with 384mb ram.

Many do list that but what makes the drives smaller is formatting. The raw size is what it is, but the formatted capacity is much less. You can ser this on sf cards easily. Format it as fat32 then ntfs, and the end (formatted) capacities will be different. Then play with allocation sizes as well ;p
If you have hordes of small files it can really eat inyo the space on ut hard drive, as well, since a file can only be as small as the smallest cluster size in the filesystem.
Even if they made the drive 1024mb x however many gb they say it is, that will be instantly cut fown tje minute you format a fs onto the drive. There is also space the fs reserves for system use, as well. Mft and such.

You can "no." all you want, but unless you have proof to the contrary, I'm going to stick with my OPINION that the phone has 384mb.
There's no way in hell the Radio, hardware addressing space and/or GPU frame buffer use 170-180mb of the ram.

There is a thread in the i9k forum that details the amounts of ram reserved in the kernel source. Just about every feature on the phone has dedicated ram, weather or not it's currently in use. That plus what the kernel shows as available adds up to 512mb. It's stupid, but that's how it is. Poor and lazy software engineering, IMO. Unfortunately, doing the allocation in a sane way and having it work in android properly is very difficult without all of the source, which we will probably never have.
It's not really any better with other manufacturers. They all do it. I think they ought to be required to disclose user available ram amounts, but nobody cares what I think.

[Q] (Q)T-Mobile hd2 shows 403 MB RAM

I have T-Mobile HD2 with T-mobile logo and colored buttons. But ram size and device memory size shown low in hardware info. I have 2.0.8 HSPL.
Is this a fake T-Mobile..
Hardware info:
RAM: 403 MB
Device Memory:663MB
SD:14,2 GB
running android? all hd2's show around 400 - 411 meg ram when running android.
Also, the first 128 meg is taken by the graphics hardware, so it is only showing 40meg lower than expected, not 160+
Yes andoroid is running on it, I read about 128MB ram but still 40 MB is lost. and why device memory is 663MB . mgldr and clockwordmod is also installed , is it related with them. Is there a way to see the physicall memory from android .
thanks for the replies

[Q] 2GB RAM or 1GB

I am using some RAM boosters and they all report that I have only 1GB of RAM. I thought this device was supposed to come with 2GB. Is there a problem with how this reports it, or is there some problem with the tablet. Does anyone know how to get the system to report the right amount of RAM, or is there a RAM tester I can use to test the RAM?
