Xperia Neo/Pro

Does any1 for sure know how much RAM there is in these 2 phones ?
thanks

Well, its quite not clear yet... but as far as the rumors go, its supposed to have atleast 380 MB available to the user. Or it may also ship woth 512MB which is standard now.

i fear that it might come with 380.. thats kind of low :/.. too low. 512 mb user available would be cool
ehh.. fingers scrossed, im almost certain ill get neo

neo/pro RAM Offical info!
These two phone have divided RAM. It’s the Sony Ericsson new technology. The RAM full size is 512mb from which the system take away 132mb for itself. Thus the freely useable RAM is 380mb. It is used only by installed programs. Thus the free RAM is always about 100mb, in the case when there are a lot of programs ont he phone too. This is richly enough. On the top of that, the size of the Cache is well bigger than in the case of other manufacturers. This new technology is developed with Qualcomm altogether .

Optimus 3D Defect?!

my Hardware Info Apps shows me, that my lpg920 has
441 Mb System RAM. Shouldnt it 512Mb??

Im pretty sure this is because of the rest being restricted or reserved for the things like the actual phone for calls and texts and the essentials so that way it wont get auto killed and stop phone working .. its the same with any phone now like my nexus said 371mb instead of 512 so 441 is alot for a 512mb phone

Hmm it says: 441Mb Ram, 137Mb in use, 304 free..

I would imagine its the GPU etc, I recall on the the GS2 had 1 gig in specs but only had 800 odd meg total.
I don't know how you have so much free mind, I have never had more than 180 free on this and that's on a fresh install.

Yeah its the same as the old pc setup where you have shared ram, so 512mb becomes 441mb of system ram and 71mb of graphics memory but remember that there are TWO 512mb chips in the phone so actually you have physically 142mb of graphics ram and and 882mb of system ram but these are halfed down to create the really fast dual channel system.

If it has 2x512mb chips they should have just made it with 1gb of on board ram and forgot the dual channel memory as it doesn't make any noticeable difference having it over the GS2 with its single channel.

That is totally not how dual channel works, if it has 2x512MB you would have usable 1GB.
Dual channel memory is basically like striping on a RAID hard drive array. It interleaves data between the two channels so that while one channel is busy it can read/write the next piece of data to the other channel. It slightly reduces the time the system is left waiting for RAM to be ready for access.
Its exactly the same as dual channel on a PC, its just phones were not really fast enough to bother doing it on until now. However as such its not the holy grail, as if you need to access data already in RAM you still need to access the RAM chip its actually stored on which might just be on the channel currently being used. It just means due to the interleaving once you start reading back its likely to be spread across both banks so can utilise both channels. Lets not forget, its still only supposed to be something like a 10% increase in performance on PC and I expect nothing more here either.
What you are describing is like mirroring and would make no sense, as it would only speed up reading back data when RAM needs to be equally fast reading and writing.
Arguably though, we would get a much better speed boost from using better FLASH memory than dual-channel RAM. Lag in all computing devices is primarily IO waits, its why even the O3D stalls when installing apps.
Its bizarre we are running the OS from chips doing 5-20MB/s when there are SSDs capable of 550MB/s now.

i think 2*256 modules

the discussion is not about dual channel memory. i know fine well how 64bit memory addressing works. the discussion is about MEMORY ALLOCATION in a dual ram system. dual ram implies that there is mirroring happening but obviously i can't say that for sure as i havent ripped apart my shiny new phone to examine it.
i think the reason the chips are cheap is literally because they are cheap. also dedicated flash drives have dedicated storage controllers and what amounts to unlimited supply of DC to hammer all that data in and out with. these sorts of things aren't feasible on a device this size. bear in mind that the entire computational system in this device is crammed onto a 2 inch by 1 inch pcb and basically everything, calculation and processing wise, is taken care of by tiddly processors with only milliamps or even microamps of power shared between them, built by the cheapest bidder with the cheapest parts.

64bit memory allocation is in no way related to dual memory or dual channel Memory.
Alex was totally right about the concept of Dual Channel and that same concept is implemented in the O3D. The Tri-Dual concept created by LG states the phone has dual core, dual channel, dual memory. The only way to achieve dual channel is by having dual memory as you need two strips of memory for it to work. Every other phone that has 512MB will have either a single 512MB chip or two 256 chips working in single channel. In the case of the O3D the Dual Memory is just a marketing term, the phone has two (or "dual") 256MB DDR2 modules which work in dual channel.
No mirroring, no 2x512MB memory, just a basic dual channel setup which you'll find in any relatively modern pc. Put two strips of 2GB DDR1/2/3 in any dual channel capable motherboard and you'll effectively have 4GB of RAM working in dual channel.

should speed the phone up more than 10% as the core and memory can work indepently /ram and core eack core decoding recording video. If the firmware can switch of a core while not idle could result in battery savings too. remember its not dual core 2x 1ghz and 2x 512mb of ram lol would be cool though

How does 512Mb. of Dual-Channel RAM compare to 1Gb. of full RAM?

I am wondering on how 512Mb DDR2 dual-channel memory (RAM) stacks up to 1Gb of full DDR2 memory (RAM)? Which is better in performance wise? Aimed at LG Thrill 4G ( Optimus 3D).

512Mb DDR2 dual-channel the better

More info please

does it have a duel core processor?
i am pretty sure that the new lg phone your talking about has a duel core processor as well which allows it to process data more like a computer, basically it can do two things at once instead of one thing.

The way I understand it (or try to) is that dual-channel memory works a lot like dual-core processors. It's not as simple as just doubling the speed (like 1ghz dual core is just like 2 ghz, or 512 dual-channel memory is just like 1 gig)
It boils down to better efficiency in handling calls to the memory. Double the available roadway, traffic goes smoother. You get a faster speed (although not quite double speed), and you do so using less battery.
I might be totally wrong, but I'm sure a google search into the difference would yield tons of reading material.

yes the RAM makes it more efficient, in handleing calls to the memory, and what calls the memory? the processor. and a duel core processor allows the computer to make two calls at once, it allows it to process data faster and more efficiently because it can handle two inputs instead of one. why do you think the numbers on processors core keep going up? their way higher for computers now. and optimus is the first phone to have a duel core, i believe, unless a apple product does but i don't have a clue about their phones.

So apparently dual channel ram is nothing but two 512mb pieces of RAM both exactly identical. The advantage over single channel RAM is that programs can access two pieces of data simultaneously whereas in single channel RAM a program can only access one piece, store it, and then read the next.
Obviously you still have the limitations of having 512mb total capacity - only being able to run so many apps simultaneously, but whatever you can run simultaneously should be able to access data twice as fast.
I read somewhere that the dual channel RAM isn't fully optimized in the Froyo build that shipped with the Thrill, but the Gingerbread update right around the corner will make better use of the dual channel technology.

[Q] Android tablet specs????

Hello,
I have a tablet GOClever TAB T75 and I have a strange caracteristics and specifications about it.
Android OS 4.0.3/4GB flash memory/512MB RAM
Hardware is:
Memory: 29F32G08CBACA [Micron Technology - MT] - 1pc on motherboard
RAM: HYNIX H5TQ2G83CFR - 2 pcs on motherboard
Correct me if I am wrong.
Flash memory some internet pages reports that is 4GB some 8GB.
For RAM I go straight to manufactor web site it's 2GB DDR3 ram module and tablet motherboard have 2pcs.
So my question is why Android OS showing only 4GB Flash memory (I think this is ROM - correct me if I am wrong) and 368MB ram (usable) and 512MB (total RAM) where on motherboard are 2pcs of HYNIX memory 4GB RAM?
Any advice and explanation?
Thank you

anyone????

Well what is your question?
If u got the tablet sold to you as a 4 GB. That is the whole system and storage total. Usually partitioned into 3 or 4 partitions.
Not really sure what u are asking, them Chinese tablets are made by about 100 different companies. Ram isn't removable if that is what your thinking

I'm kind of confused.
The tablet is 4Gb of internal storage and 512Mb of RAM. There's really nothing more to be said. Android is only showing that because that's what is there. If you got scammed that's another issue - but if it was sold to you as 4Gb flash memory and 512Mb RAM then that is what you do have.
Like ronedogg said, the 4Gb is all the internal memory, including space for your ROM (software that makes the tablet run). That's all there is to report because that's all there is.
The RAM might be "2 pieces" of 254Mb RAM. It's not 2Gb - even if you have a copy of a tablet that's supposed to have 2Gb RAM you do not have that, you have 512Mb RAM. Nobody is putting 2 pieces of 4Gb RAM in Android tablets - you only see that in Windows tablets that have Intel processors and tend to be very expensive. Did you pay over $1000USD for this tablet ? I hope not. :silly:
Your RAM is probably 2 modules of 254Mb RAM, if it's even "2 pieces" at all. Generally when reporting RAM they will tell you total RAM, not some number that you multiply, anyway.

Hello,
Thank you for informations. I payed less then 80USD for tablet (used - not new).
Even that tablet have 512MB ram when it's on Android shown Total Mem.: 368,36MB ram (used for OS around 150MB) so Free ram that I can use is only around 200MB (on stock rom).
So that's I am confused why have 512MB of ram and usable only 200MB. Or it's just SW blocked???
In attachment are specs for module.
Thank you
BR

Well, what is the Ram that is being used going toward? The system can take more than 150Mb from what I've read.
I don't know what you have specs for, but I'd be willing to bet my firstborn that it's not what is in your device. You could open the tablet up to confirm it yourself, but if it was sold as 512 and reports 512, why do you think it would be otherwise?

8GB or 16GB - Does it really matter?

There seems to be some good deals around on the 8GB model at the moment but not for the 16GB. Obviously more memory is always better - the phone it will replace is the Samsung S2 which has been memory bound, however with an SD slot in the Moto G will it actually be an issue having less onboard?
I know that Android M has ability to use SD cards for system storage and that it hasn't been released yet. This can only be a few weeks away?
At near half the price of the 16GB, is the 8GB a much better purchase?

What about the difference in RAM? 2gb better than 1.

Oh, I hadn't appreciated that - thanks for pointing that out....I guess it could be a bit of a dog without enough RAM?

Size does matters my friends....

My 1GB RAM model is pretty great for the price. Battery life is fantastic, however having the low_ram flag enabled in build.prop is a bit of an issue for some apps.

1 GB RAM vs. 2 GB RAM really does make a difference.
Initially I bought the 1 GB Moto G, as here in Germany the 2 GB version is only available with a hefty price tag via Moto Maker. Later on replaced this with a 2 GB Moto G ordered from Amazon Italy (less expensive than the 1 GB version here in Germany ).
At first glance performance is pretty much the same.
Though the 2 GB version can keep more apps in memory in the background.
With 1 GB I had sometimes the problem that Android did kill e.g. the Music player running in the background while surfing the web with Google Chrome (Chrome is a huge memory hog).
So far I didn't have such issues with the 2 GB Moto G.
Also the 2 GB version is for sure more future proof. Which is important if you are not willing to buy a new phone every 1-2 years.
My previous phone was a Samsung Galaxy S Plus. Which was perfectly ok for my everyday tasks since I think back in 2011 until a few weeks ago - thanks to good custom ROM support.
What made me exchange it for the Moto G in the end was the performance bottle neck caused by the lack of free memory (512 MB) and not the CPU or the rest of the hardware.
So I hope thanks to 2 GB RAM the Moto G will last me at least as long as my old Galaxy S Plus.

It doesn't really matter if you picked up a high speed SD card and use Marshmallow. I've seen no problems with the external SD -> internal SD feature.
About the RAM difference, you should use virtualized RAM as soon as you can if you're using the 1 GB model.

I only paid the extra because of that extra 1gb of ram. Believe me...it matters!! If you want to keep app updates coming, xposed modules running, etc etc....you need that extra ram. This is a great phone out of the box, but if you're here and you're asking, you're probably not leaving it untouched

I've got the 1gb model, and never found myself wanting more. Of course I keep my use simple. But for what I do, its more than enough.

My previous device had 1 GB of RAM. In my opinion, the 2 GB is definitely worth the extra cash. The multitasking difference is night and day to me, and I no longer have to worry about what is running in the background slowing the device down. I do a fair amount of gaming on Android as well, it is nice to sit back and play a game with Pandora or similar running without the OS killing it to free up memory for the game.

The 2gb makes it much more future proof. I have the 2gb version and I have never had to close any app most of the time. With 1gb of ram, you will have to close apps much more often making multi tasking a little more difficult.

What is 'virtualized ram?'
I'm in the boat with the 1 giggers and I'm curious how to do that.
I mainly use this phone for office tasks and it performs incredibly, but hey! An increase is an increase right?
Also curious about the posters response about low_ram flag.

In Kernel Adiutor there is a Virtual Memory section and if you scroll down all the way there is a slider called Z-RAM. You can adjust the size of the memory there. Instead of using a swap file this compresses the RAM, making room for extra storage. But it has downsides, the extra processing required to compress the RAM eats the battery at a slightly faster rate.
I haven't heard about the low_ram flag, I'm afraid that I cannot tell you about it.
