Vega has 512 MB of RAM but the tegra 2 GPU takes 128mb , so "real" Ram memory is 380, as seen on Set Cpu.
on LG device it is possible to change value from 128 to 64 MB RAM of the Tegra 2 SOC,they say initially was set to 64 ,as seen on this post
I assume this "hack" has to be implemented through a kernel change?
Am i wrong?
Could someone with skills have a look into it?
Maybe with more memory apps would run more smooth...

Greetings - i found out that there are 2 versions of the HTC universal out there
a 64 MB and a 128MB version.
does this mean the Ram size or the ROM size?
regarding to PDAComparer where they compare the devices - ALL of them have 128MB ROM and 64MB Ram
got a VPA4 from vodaphone
(1) what is the difference
(2) do i have a 64 or a 128 device?
There is no original 128MB version. The ones you see are made by exchanging the 2 32MB ram chips with 64mb ones.
If you don't know, you have a 64MB device. If you bought it new, then it's 64MB, 100%. If second hand, the seller would have told you if he'd made an upgrade.
The difference is less memory problems : being able to run WM6.5.x and having enough memory left over to actually run programs is good. Or so I presume, I don't actually have a 128MB device.
I am wondering what is the deal with our HD2 (TMOUS version I have), supposedly our phones have 576mb of ram internally, but on every rom I have tried I am limiting to something much lower according to running services or quaddrant system info, I have flashed 2.15.50.14 radio which is supposed to have the 576mb of ram, from my understanding the phone shares 128mb of ram for video which leaves 448mb to use but I don't even have that according to running services. According to my phone I am using 90mb of ram and 292mb are free which is a grand total of 382mb of ram my phone has access to, where is the other ram?? I am getting really frustrated searching google and stuff trying to find answers, I know its a difference of about 64mb that I think im missing here but its the principle that our phones should have 576mb of ram and im over here getting 382 on every rom I try. Anyone have some ideas on this??
I would like to add that I just checked quadrant system information and this is what it says.
Memory:
Total: 421004 KB
Free: 172356 KB
Inactive: 46692 KB
Doesn't this mean about 50mb of ram is inactive? I don't understand the deal with that.
The missing ram is taken by the GPU.
Please reread my post completely, I think you missed something, I covered the gpu using some of the ram in my original post.
i would say those figures are 421MB total ram, 172MB out of 421MB is genuinely free, and 46MB is loaded with apps that have stopped but not been unloaded from memory.
Example, mine says
421004
80228
85188
i start a few programs and go back to quadrant, and it changes to
421004
85140
88916
As mentioned, the graphics chipset takes up 128 meg, and it grabs it before the OS has even loaded, so it never sees it, so you start with 448MB total. For some reason Android loses 25 or so MB, and so we all (tmous and regular) show total RAM as 422 or so.
As said the system and the GPU takes it. Come on do you think the guys who made linux would really be as stupid as to just leave out some ram for no one to use or for it not be used? Or any person who makes an operating system?
Hello,
As you may know in latest 4.4.4 update, there is only 1.1 GB ram available to the system and something around 800MB is dedicated to GPU ! some people argue it is because of high resolution of screen (2560x1440) but still 800MB seems so high to me. my HTC One m7 has a 1920x1080 screen and it has 1.7 GB ram available which makes it only 200MB dedicated ram for GPU. by same proportions nexus 10 should not need more than 300MB of dedicated GPU ram. I know it is not that simple and they use different kind of SOC but I would like to play with this value and check its impact on system.
does anyone know how it is possible to change the dedicated GPU ram in Nexus 10 ? it should be somewhere in kernel but I dont know if it is configurable or a constant value in kernel code.
Regards

It is not configurable, it is code changes and I never have time to work on this device anymore due to work load on my real job.
Hi
just ran CpuZ on my Exynos model and it indicates:
Total Ram 3580MB (1190 available at the time of the test)
Internal storage 24.86GB
I know about the 1000 vs 1024 story, but even with that in mind, those figures look quiet far from the numbers announced (4GB & 32GB) by Samsung???

I'd also like an explanation. I've no doubt there are 4gb of memory soldered onto the motherboard, but I'd like to know why only 3.5gb are reported available.
In 32-bit days, before Lollipop and ArmV8 architecture, devices always reported a maximum of 3.5gb available because that was all that could be used on a 32-bit system. I'm wondering if this ram reporting issue is due to some kind of 32-bit limitation on our 64-bit devices.
If anyone really knows the technical reasons for this, I'd like to understand what's going on, just to satisfy my curiosity.

Is some of the RAM reserved for the graphics chip, like a PC has system RAM and video RAM for the GPU?
Some of the RAM around 512mb is allocated to the GPU, and for the storage, 8gb is used for android system partition
Hi,
I hope everyone is fine. Nexus 6P has 3GB RAM. I want to reduce the RAM size i.e., I want to bring RAM to 1GB or 512 MB for my research purpose. Can anyone please guide how can I reduce RAM size using ramdisk and how can I use that so that my application only see 1GB or 512 MB?
Thanks
