Only 528MB of RAM? [Solved]

Hi, I've just noticed that if I go under Settings>Applications, I see 144MB used and 386MB Free, resulting in a total of 528MB of RAM, so I am wondering what is going on with the almost half gigabyte of RAM missing, is this allocated for the OS?

Buddy, what you're seeing is free ram and ram used by your apps. The ram you are NOT seeing is being used by the actual OS.

thanks buddy, that is what I was actually thinking.

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

[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?

Hello mate, 1gb is not shown as it is actually dedicated to gpu
Not a nice way for Google to sell stuff without being clear, but that's the way it is unfortunately

I have the exact same question

I see in the runnings apps section in settings that the total ram being shown is just 1 gb

How much is the total ram in your Nexus 6P?

I just noticed that on my 6P the total ram the os reporting is 2.6Gb. Is that normal? I can't remember but I am pretty sure on my nexus 6 was more. Anyone else noticed this?

Normal.

No, but is very small amount over... In the picture you see 700mb free.. Isnt that low?

It's like the base 640k from old days, or even better, that space between 640k and 1meg that was mostly reserved and a pain to use.

yeah my operating ram is low as well its always around 700 mb o soI dont see if why if they knew they were gonna use so much why not make it 4GB instead of 3?

Total: 2.6GB
Average used: 66%
Free 0.88GB

Thanks, I was wondering if it's just mine...

I'm curious why phone, while not running much, reports RAM usage over 50%.
Is this normal or do I need to troubleshoot?

The free ram thread for every phone. Android is based on Linux. Linux runs best when it uses as much ram as possible and frees ram as it sees fit.

OK that answers my question. Thanks for the link.

No problem. We all get used to Windows which works better with free ram.

But in the G4 you have more Ram to use. Just like about 1GB. And here on the 6P less then 1GB

The stock Google bloat system & apps will use more memory. It always seems to improve free memory with custom roms and their optimization tweak's!

You are missing the point. You do not want free ram. In Linux based operating systems free memory is wasted memory. It optimizes the ram for the apps you use most frequently and helps them to load faster. The 6P has 3gb of ram.

Thank you sane people. I was getting tired of telling people this fact about Linux ram management.

I know my nexus is sitting around 60% usage from just the OS / UI but my MotoX 2013 only used maybe 20-30%.
My moto also claimed 2GB RAM and it showed all 2GB, same with my Shield tablet, on any app that shows total RAM yet the nexus only shows 2.64GB.

Unused RAM is wasted RAM.

Question about my s7 edge memory RAM

I recently got this s7 edge and I found the memory RAM is only 3.5gb instead of stated 4gb, is it common? Things like 1024 and 1000 conversion couldn't explain the big gap.

That's user/app-accessible memory. The phone itself reserves a decent chunk for the operating system.
Mine reports 679MB reserved, 2GB used, and 1.3 available. Add all that up and you get 4GB.
