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

Can someone confirm the amount of RAM available?? (Only takes a few seconds)

Can someone confirm the amount of RAM that is available to the user? There were rumors that only 512mb was available (leaving the other 512 for the laptop dock). However, I've also heard that around 800mb was available to the user (meaning the full gig, essentially). To easily see this, download Android System Info from the market, open it, and on the first page/tab you can see RAM (total available, etc.)....
Thanks in advance!

I, too, would like to know the answer to this. It would be pretty weak of Motorola if it only allowed 512 of it to be used.

+1.
I would like to know this as well.

Bump

It says 425M available + 172 if I'm not mistaken.

From android system info there is 818MB RAM available, but after killing all threads the free RAM is no more than 510MB

motoblur/android cant be gobbling up 512mb worth of RAM. perhaps some is allocated to webtop? i would be very dissapointed if that were the case.

Thanks guys

Mine says 818MB with 432 available.

Bit advanced task killer only shows 394 + 111
Sent from my MB860 using XDA App

Mine says..
Max: 818MB
Free: 280MB

Maybe it allocates 512mb for webtop and when the other 512mb (or whatever size after format) runs out it starts using the 512mb from the webtop

Jesus i hope that's not true, there has to be a way to disable that.

Hey guys, those of you with the device, go into the "tasks" tab of Android System Info.....here you should be able to see EVERYTHING that is consuming memory.....in a task killer, you likely won't be able to kill everything (and you shouldn't). For example, on my inspire, there are a lot of core processes and things that wouldnt show up in a task killer (like phone, etc.). A close look in this tab should give us a clearer picture. It does, however, appear that the full gig (essentially) is available. My inspire's ram is 768 and my max ram is 623, so the atrix seems somewhat comparable in the proportion of available ram.

[Q] Ram info on your tab?

I want to know that the total ram showed in settings=>applications=>manage applications=>running applications. My retail version showing 420mb free plus 173mb used ram total 593mb ram on the system instead of 1gb. Can someone plz check in their tabs either retail or io version plz. Thanks

I would guess a significant portion of your "missing" RAM is set aside for the GPU. The ended up being the case for the Galaxy S phones - 512mb RAM, but only 330 available for the OS and apps.
Still, 600mb is a pretty respectable amount for these devices.

My Xoom shows 120MB used and 379MB free. So the total amount shown seems normal. I would like to know why there is so little free memory on GT10.1 if it's a stock Honeycomb?

It's currently 169 / 412 MB on my GT, so I guess about 400 MB is set aside for Graphic processing.

Reboot your GT 10.1 and then report here the RAM statistic ... *please*.

After boot my 10.1 I/O shows 143MB used and 476MB free.

true, considering the ipad manages to run smoothly with just 500mb

after reboot tab showing 169 used and 449 free. Running stock honeycomb 3.1 retail version tab.

I've got 148 used and 412 free

I second all of the above. Mine is usually around 600 MB or less in total. So I guess that's normal? It wouldn't have anything to do with the tab showing hiccups and lags after using it a little bit? Everything was very fast when I used it for the first day and then it started slowing down, especially when I run live wallpapers. Did any of you experience that? It breaks my heart to admit that iPad2 (even iPad) runs so much more smoothly than my Galaxy.

ASUS TF300 the first Android device to TRULY have 1GB of RAM?

I posted this in another thread but thought it was worthy of its own thread.
I've owned a lot of Android devices with 1GB of RAM - Xoom, Galaxy Tab 10.1, Galaxy Note, and the original Transformer. This is the first android device that actually shows 1gb of ram. Every 1gb phone or tablet I've had only lists around 750mb total, and then only about 400 or so free on a fresh boot. The explanation has always been that 1gb is shared ram and that the mixing 250mb or so is for video ram. You can see total and available ram in an app called OSMonitor. Anyway, the tf300 actually shows 1gb total ram, and 750 free on a fresh boot. So that's an extra 250mb of usable ram over other devices.
Thoughts?

The device has more as 1GB RAM (1,2GB maybe)?

It's advertised as 1GB of RAM, so either it has more actual RAM (1.2 like you suggest) or it has dedicated video RAM somehow.
It's very possible this is inherent to Tegra3. I do not have any Tegra 3 devices to check. I'm going to ask in the Prime Q&A section.

Obviously either a design flaw or outright false advertisement. You should sue them for giving you more ram than advertised.

WTF? I'm not complaining I'm trying to understand it. It's different than every other Android device.

Goodintentions is known to be sarcastic you will learn that in time. Most likley it is because tegra 3's gpu has its own dedicated ram so it does not go into the system ram

That would explain it. do you have a source link to back that up? not finding anything in a google search.
Thanks.

Everything im finding is that it just has the 1gb of ram, but possibly the way it handles it is different and may expand or shrink that video ram depending on what it needs.

just general info

also is DDR3

Yeah DDR3 means it's faster and has more bandwidth, but that wouldn't affect whether the system has dedicated or shared video RAM.

Is it possible that it's just more efficient in the usage of it's 1GB of ram than the previous products? I can't find any mention anywhere of Tegra 3 specifically doing anything or of the TF300 having more secret ram or anything.

That was the first thing that I noticed about this tab, is that the memory management on this tab is awesome. I can be running GTA3, have two or three tabs open in the browser and also be streaming music and the RAM only drops to about 550MB. At idle on a fresh boot, around 750MB free at idle, and If i do a task killer it will jump up to 830MB temporarily. I can only think it's becuase of the Tegra3 CPU. Regardless it's nice to see a tab with so much free RAM.

No because we're not talking about FREE RAM here we're taking about TOTAL RAM. either the system has more than 1GB or it's not sharing RAM with the video card.

Huge amounts of free RAM is not something nice to see; it's a pointless waste. I guess that misunderstanding is still pervasive in the "OMG tasks are in RAM MUST KILL THEM" community ...

Huge amounts of free RAM on a fresh boot is a GREAT thing. It means that the OS is lightweight and not loading tons of bloatware into memory. Now after using the tablet and opening tons of apps the free RAM should go down, if not then yes it is wasting RAM by dumping stuff out of memory.
But besides that the topic at hand is total RAM. more total RAM means more apps can stay in the background which means better multitasking.

They all actually have 1GB of RAM. The difference is simply that some chips separate the video RAM and the system RAM, where others are able to use a shared memory space and dynamically allocate RAM to video as necessary.
Most likely, devices with higher memory bandwidth will be able to use dynamically allocation because the extra bandwidth provides the overhead necessary to minimize performance impacts should the GPU need to pull more memory from the system on the fly.
On Tegra2 devices which were limited to 1 channel of 32bit ddr2, there is much less memory bandwidth than on tegra3 with ddr3 (or dual channel ddr2 like ipad). In this instance, it would cause a performance hit to have to free up extra memory from background tasks and then reallocate it to the gpu - so the solution is to just partition the entire memory into two sections each of which are generally large enough for both their respective duties: video ram and system ram.

current reviews & memory benchmarks have shown the 300 ddr3 ram shows no Performance improvement over Prime ddr2. developers here can probably make the most it though.
Finally you all have your own section. CONGRATS!

he makes a great point. although no memory improvements shown in benchmarking, what he is saying could be seen as an improvement though. good info.
300 is not the only Tegra3 kid on the block with new DDR3 ram. Toshiba just released their Tegra3 Excite 10.1 in. tablet. it has gorilla glass, 1280x800 display, and 1gb DDR3 ram. available in 16 or 32gb. you can also order a 64gb.

500 bucks for a 32gig.... No sir.

In the spec section Amazon lists the TF300 as having 2GB of RAM...I'm sure its a mistype though.
http://www.amazon.com/Transformer-TF300-T-B1-BL-10-1-Inch-Tablet/dp/B007P4YAPK

Running 2.6 Kernel mine shows 983,2 MB of Total RAM.
After installing some nec. apps it drops down from ~850 MB to ~630 of
available RAM. After removal of most BW it shows ~820 MB of free RAM.
It's normal behaviour. It just acts like the Prime. Open it und you'll see a Prime with some faster MemoryChips & an optimized board design
I just hated my Prime for many reasons, but I really love this one
They've improved very much here

What's your maximum available ram and how to increase it?

I'm only getting 1.58 GB and after the reboot my ram usage is like 1.31/1.58. I know it's 2GB device. So the question is why only 1.58gb can be used and how to increase it to 2.0gb? Anyone?

Cause probably the rest of the ram is used by core (not Android os) and hardware

Mine is 1.82 GB. Which is normal due to the conversion discrepancy between MB/GB.

1.82 or 1.72. Can't remember and don't want to look right now
The only way to increase it is by using swap. Either with an app like the rhoesoft ram expander (I think thats how it's wrote), or with a rom feature. But the ram you get with swap is not as fast as real ram. It will also degrade the life of the storage in that it is being stored. You can google more info about swap.
Are you sure you're reading it right? I usually have 1.2 GB ram free.
If you have 1.31 from 1.58 free then maybe you should consider uninstalling some apps. Cuz that's an unusual lot of ram usage

2000/1024 isn't 1.82. And I don't know why mine shows 1.5. That's a 300 missing. I'm on 4.4 tw.

It's just like HDD's. You buy one with 500 GB storage and when you set it up it shows only 480 GB or so.
And yes, samsung kinda ripped us off. 9 GB of internal storage is not 16! and 1.82 GB ram is not 2 GB! It's basically false advertisement what they are doing..
