[Q] any way to retrieve back the 1Gb RAM from GPU allocation? - Nexus 10 Q&A, Help & Troubleshooting

Hello, I noticed that, from 4.1 to 4.3, ram dropped twice.
Now it's just a bit more than 1GB.
Well, I bought a device with 2GB RAM. I know, that's not completely wasted but allocated for GPU.
But... 1GB? On 4.1 we had 1.6 GB of real free ram, then 1.3 on 4.2, now 1.1!
And on kit kat? Maybe 512 MB?
Anyway. There is any way to get it back? Custom kernel? Custom ROM? No one tried this? I never compiled a ROM or kernel for android, so I have no idea where to start.
I think that's not an honest way of upgrading. 2GB was high end, and in android world would have been a lot of ram for a lot of time. 1Gb is just barely enough... It's already killing application, usually launcher or keyboard.

There is lots of information out on the internet for this very topic. I believe it has to do with more memory allocation set aside for GPU or processing.

I know the theory, I don't care why they did that.
It's like selling it for 2GB, then getting 1GB back, then... It's a 1GB tablet!
They should put 1GB for GPU and 2GB for RAM. You know, RAM, Random allocation memory, something that should be accessible from every application, not just locked there waiting for the GPU.
320, even 512 could be acceptable as a sacrifice for GPU allocation.
On PC you can even allocate 64MB on Intel chipset for GPU... And on PC you can have a lot of spare memory.
And on a tablet...One of the most powerful, and what should have been a top-sell for Google, you reserve a gig for GPU?
That's crazy. I almost feel scammed.
On topic:
Yeah, ok, but... If I'm not going to play. Can I flash a different kernel with some different init script?
I think that's something kernel-level. I didn't even rooted my Nexus 10, so I have not a lot of information, but it's not a common thing for tablet > 1920x1080 to allocate a gig for GPU. That's not right... I feel robbed this way.

I also feel the same way. On the nexus s forums there is a mod for kernels called bigmem, which takes some ram from some of the components and make it available to the system, for apps. I think the 1st ones who did this are the cyanogenmod team themselves, in one of their roms.

A kernel dev could do some mods to give more RAM to the user instead of reserving it, lots of phones have kernels like this. Also things can be removed from the ROM to free up more RAM to the user instead of it being taken by system services. I think this is also a lot of the reason we have less free now with Android OS version upgrades, because Google is adding a lot more services and these services take memory. We used to have 512MB of memory reserved for GPU, this was increased to 768MB in 4.2.2. I havent looked at the changelogs for 4.3 on this tablet but I dont think the GPU specifically got more reserved. That other 256MB lost over these couple version looks to do more with system services than GPU reservation.

That is my interest. Is anything available? I don't play a lot.
On an Android device, memory means future proof. Not totally, but a big part plays there IMHO .
1Gb is becoming low end, my galaxy nexus swap a lot if I don't remember to swipe away some application from the application preview button. And my galaxy nexus have 1gb - something like 230 MB allocated = almost 750 mb free. Not too far from 1100 MB free.
It will take a few application update, newer g+, Facebook, Google music and chrome et voila... You launcher will have to restart every time loading your 80 application, and the app will lose data swapping between applications (meaning that it was killed to reserve memory). It' s already happening and it' s sad, since it's a high end device.

I do not think anything is available now, everyone seems to be concentrating on adding features and functionality than slimming down and freeing memory. An example of what can be done is if you look in the GNex section of development there is a guy named mpokwsths with his "Mpokang kernel" that is removing things and slimming down the kernel to give more free RAM. I believe his thread says he is up at 772MB free on the GNexus now at boot. But no I dont think there is anything yet for the Nexus 10

The rumor is that KitKat will be optimized to run on low-memory devices down to 512 MB (the article mentions android 5.0 Key Lime Pie, but it's likely that's what's being released as KitKat instead) when it comes out in a month, again according to the latest rumors. Presumably it will run a lot better on the Nexus 10, but we'll have to wait and see. At least we'll get it within a week or two of release, :highfive: as opposed to the many months most non-Nexus owners have to wait.

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)?
Gesendet von meinem Galaxy Nexus mit Tapatalk 2
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.

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.

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 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.

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.

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

Using full ram with root

I've read that 1 of the 2gb of RAM is used for the touchwiz so you effectively only have 1gb. If you install a custom rom, ie. cyanogenmod, do you get to use the full 2gb then?

Pretty sure its ICS that takes up the space and its not a full GB. I don't have the phone but a friend has around 1.6 - 1.7 Gigs free at max.
I don't think that would work out, considering the international GS3 has 1GB of RAM and runs TouchWiz.
So much confusion, let's spell this out. First of all our phones have 2gb ram, period. The GPU requires about 0.38gb of the system's 2gb because it doesn't have its own onboard memory. So no matter what software you run, you'll be starting out around 1.62 available.
Different operating systems, frameworks, skins, and applications will have different memory footprints. Touchwiz is probably a bit heavier than AOSP (CM/AOKP), so after a clean boot you'll probably have more free ram running an AOSP variant.
Honestly its all kind of moot at this point however, because I doubt in either situation most people get anywhere near using the all remaining RAM with current ROM offerings. Key lime pie may be another story.
Yeah to his point about not using the RAM is just stupid, unused ram is wasted ram meaning you have it for nothing, for example on stock cm9 you got 1.2 gb free most of the time, 500-600mb free, touchwiz manage ram better but still leaves a lot behind, look up what ram does and you will understand why unused ram is useless

Isn't it ideal to have unused RAM so that when you open apps and multitask, you the memory to keep them alive? Maybe I'm misinterpreting, but if we never had unused Ram then we would never be able to multitask, right?

This is quote from something I read in pc mag
" This has to do with extremes. Remember that every so many cycles (don't remember on current ram), your memory has to completely refresh its contents. If you have an extra 16GB that you never use, then you waste time refreshing all of that ram. Also on this note, higher densities, and larger quantities are harder on your controller. For maximum speed and stability, use ram appropriate for your usage pattern"

While that is true, ram come in discrete chunks and 2 gb is noticeably better than 1. At a certain threshold the memory manager kills off old apps to free up ram. More ram means more recently used apps remain loaded and available sooner plus i have no issues with many pages open in a browser. I typically run with around 600 mb free. Only my dell streak i would often be under 100 and unless i manually closed apps it really bogged down.

New Nexus10 shows total ram as 1.2gb via android assistant

New nexus 10 user here. came from an htc flyer. Anyways, android assistant shows total ram on my device as 1.2gb or so. Specs say thing has 2gb. Does any ones else's device report that or is that the way android assitant reports it? I am just wondering if i have a new device with ram issues. Also, with not much running, this things shows available ram like my Vivid (about 300gb or so ) and it is supposed to have 2x the amount of Ram.
Thanks for any insight.

What your seeing is correct. The Nexus 10 has 2GB of RAM on the motherboard, but 800MB of it is reserved specifically for the GPU. I still think it's kind of cheap marketing, but meh.
Before 4.2.2, only close to 400MB was reserved for the GPU, but apparently you could go past that limit in some cases, and it would cause userspace RAM fragmentation.

Not cheap marketing, laptop manufacturers have been doing this for ages with integrated video cards. It's a little deceptive but it's the norm for this. I the Galaxy Nexus also did it. I am not certain but I don't think any mobile device has dedicated video ram, I believe it just is not reported as missing.
The Galaxy Nexus shows as having 893mb of ram.

I agree it's kind of normal, but it's how much is missing that still bothers me. The Galaxy Nexus is said to have 1GB of RAM, and if what you say is true, you're missing only a tiny bit over 100MB (which, is nothing imo). The Nexus 10 on the other hand is missing nearly half the advertised amount (not literally "missing" but not usable under normal conditions).
I'm pretty sure most laptop GPU's don't take "that" much RAM either when it's not dedicated (most I've seen was 512MB shared video memory, on laptops containing 4GB of RAM; very small amount really)

the more i know and read about the n10 the more i feel being ripped off
Ripped of? For around $400-$500, you're getting a device with extremely high resolution (highest in its class EVER), a 1.7 GHz CPU with up to 2.1 possible, a software and hardware support guarantee from Google, an extremely competitive GPU, and future-proofing with the latest Android versions for years to come.
That sounds like a pretty damn good deal to me. I know I've loved my N10.
If you're having issues with your device its likely a manufacturing fault, just return it to Google and get a new one.

Rip off?
Have you checked how much usable space you have after formatting a 1GB drive? The N10 delivers the specified HW but there is always overhead required to use it, no matter which OS you have. That is just a fact of computing. I would argue that you get to use ALL of the N10 hardware when you accurately account for the a running OS and apps.
Compared to Win8 RT, Android (Linux) is a skinny fashion model. Go look at the Win8 RT tablet specs then see how much usable HW is left after it boots up. Here is just one example.

The 2GB ram on the device must accommodate both the operating system and graphics Ram before any apps are loaded. So what you see is normal. This is no different for laptops. Also the 16 or 32 GB internal storage shows less after formatting and Android OS plus Google apps (Gapps) are installed. At least with the Nexus 10 you have much less bloatware compared to other Tablets (eg. Samsung).

Nexus 10 has never shown 2gb available, I've had it since launch and I believe the most I've ever seen was back on 4.2 was about 1400MB or so, and it has gone down from there on each update. You never get what they advertise on the box, every single one of my devices has less than whats advertised, my Note 3 is supposed to have 3gb available, but really its only 2.38 after its said and done..
1098 is normal on 4.4.2 for N10, I've attached a shot from mine ... I can only assume most of it is being reserved for the GPU and its super high resolution.

Hi,
As already stated here, just clearing a little the information for you .
The Nexus 10 has a huge screen resolution, therefore it requires a more powerful GPU, even having a pretty powerful graphic processors which is the MALI, it's not powerful enough for the 1600p screen, so they allocated ≈1GB to the graphic unit to prevent any possible issues.
Also, there are some apps running in background, so it takes some RAM too.
Hope this clarifies a little ,

Thank for your help:good:
I did notice that with slim kat 4.2.2 I have 1647 ram available and with 4.4.2 slim kat I had 1099.
so I thought that Kit Kat uses less RAM but I don't really see it with those comparisons.

The Nexus 10 is suppose to have "2GB" of ram, but my Nexus 10 only have "1099"

In later software releases, they decided to allocate more of the ram to the video. Search this forum for a more detailed answer if interested.

I remember finding this out a few years ago and being pretty upset at the time. The tablet advertises 2GB of RAM, and yet about 1GB of it is only usable for the expected advertising purpose.
It's like me advertising my computer has 12GB of RAM, meanwhile, 4GB of that is dedicated to the GPU (which on it's own isn't really a problem, but it would make more sense to advertise 8GB)
Even then it would still be 12GB.
Let me get a little technical.
If you have an APU based PC, the GPU is on the same die as the processor. So when you use the GPU portion of the APU, it will use the RAM. How much? It depends on the load.
You can still use all of it though, so it isn't a problem. When you aren't using the GPU, all of your RAM is available.
