So 2GB RAM are only 1,8 GB, Sony uses its own values for marketing and counting? - Xperia Z5 Compact General

Just seen that.
They advertise the compact as a 2GB RAM device, knowing that they only deliver 1,8 GB.
Anyone else seen that before?
I do not think it s a way to free up to full 2GB as advertised?
Other brands deliver 2GB if they tell their devices have, why not so z5 compact?

Where's the source on what you're talking about? The RAM is always going to be used up by something - the OS, launcher, etc. You're not going to turn the phone on and have exactly 2GB of RAM available.

Sure, but it says 1,4 out of 1,8 used, 3xx free.
That means Limit is 1,8 as shown under Memory, not 2 as advertised. Never noticed that on a phone before.
As soon as the device is running memory is used, but it should say out of 2,0 not 1,8?

Also - not sure why you'd want to specifically blame Sony for this
Coming from the technical, developer background:
you have to consider that device drivers also eat up quite some memory/storage (best example: the Galaxy S, GT-i9000: 512 MB advertised, at best 300 [384 at best] available)
it's only the device drivers, it's the kernel (system) itself that also needs memory
so you'd basically have to advertise e.g. 2 GB but plug in 3 or even 4 GB to have full access for e.g. apps

All companies define a gigabyte to be 1000MB, and a megabyte to be 1000kb, etc etc. In reality it's 1024KB per MB, and 1024MB per GB.
You never fully get 2GB, just check your computer eg. your hardrive might be 1tb big, but in reality its only somewhat over 900gb? 16gb ram might only be 15.9 gb!

Thanks for the notice though

The topic is...that in Windows the full RAM without any convertings of bits and bytes is shown.
Only Hard Disks have that "exchange" from 2TB to 1,8 e.g.
So I was not awaiting that on mobile RAM too.

Really ?
I gotta take a look next time I booted into Windows,
Android sort of is Unix, Linux - so that is more to be expected

yep
BIOS: 3096MB a 4GB Bar
Windows too
But I got an explanation somewhere else as smartphones use flash memorys equal to SSDs so its the same 1000 isnt 1024...thing there )

Plus, on android some ram is reserved by GPU. Unlike dedicated graphic card on PC/Mac which got their owned ram but our GPU shared with system memory.

Same thing as onboard GPU on desktop systems so?
Well 3096 per slot, using several 4GB bars, no 32 bit limitation)

HTC & MS are Cruel & Manipulative!I know u visit thi

The new Dell Axim X51v has 256MB RAM on WM5.0. Why the hell didn't the 'Worlds' Most Powerful fu..ing phone' get this? :evil:
HTC..you are are truly wicked!!! :evil:
You build the Dell Axim don't you? :? Microsoft..you test your software don't you? Stupid question.. you obviously don't, but are quick to charge for incomplete and unpolished software. In contrast you are quick to prosecute people who actually copy your buggy software.
HTC...how can you make new geneeration devices with under-powered bits? 64 MB RAM? C'mon!! Couldn't you have at least given us 128MB RAM so we don't all worry about memory management? Are you listening? Aaarrghh... who cares right :evil: ??!!??
I can't make up my mind if the Universal is an excellent technological achievement or an overpriced, overhyped piece of poorely stiched together meta-technologies. :roll:
So now, I have to learn to become a technology guru, not because I want to, just so I can use my bloody phone. :x
I give up.
No need to have a fit mate!
You've got your numbers mixed up. The Dell Axim has 256MB of ROM, and in fact has 64MB of RAM (same as the Universal).
Windows Mobile 5 introduced persistant storage which basically means everything is stored in ROM, rather than RAM as with WM2003. This means you now have the full amount of RAM available to you, and 64MB is loads!
There's also the issue that if you double the RAM size you double the memory power requirements which affects battery life.
Take a look at this article which explains it all a lot better than I can, and you'll see it's actually a really good idea to have 64MB:
http://blogs.msdn.com/windowsmobile/archive/2005/07/14/438991.aspx
Persistant Storage
no: 1
Thank you for your informative reply & I found the provided link very useful too. Well, they should have still given us at least what the Dell has got. Except for the keyboard and phone, we've not got much more and we pay more than double! Anyway, thanks again.
I'll discuss these issues with my shrink at our next meeting, I just can't control myself.
What is in the Dell vs. other PDA's that HTC makes is not really something that is comparable. Dell pays HTC for making the Axims. I imagine that if Dell is willing to spend the money on higher specs, they can do that. HTC doesn't decide what's in the Dell Axim, Dell does (for the most part). HTC then engineers and builds the devices.
On the other hand, HTC makes the JasJar for i-mate. i-mate decides the specs they want (with some input from the phoner companies I'm sure) and they pay HTC to make their PDA's. So, just because HTC makes the PDA's doesn't mean they are all going to be same spec-minded or the same cost. It's up to the "brand" (HP, Dell, i-mate etc) what HTC makes for them.
As far as deciding whether the Universal is an excellent technological achievement or an overpriced, overhyped piece of poorly stiched together meta-technologies, it's a little bit of both. It is an excellent technological achievement AND it is overpriced

It's a big shame!!!
They promised us heaven, and I find myself in hell!!
This device is a dream, but without minimum 128MB, better 256 MB of RAM, becomes hell, and useless!!!!!! :twisted: :twisted: :twisted: :evil: :evil:
256Mb of Ram?
I have a (old) pentium 4 laptop that works well enough with 256Mb of Ram. Doesn't that seem a bit excessive for a PPC, especially as your battery would only last for about 93 seconds?!
As i said, 128mb, or 256 MB, do you have a JasJar? Do you know how it feels, to spend 1.094 euro plus 174 for and SD card ultra speed 2 GB, an not being able to use it at all, with the very simple applications? My Treo 650 runs much better!!!
And then, I shouldn't cry for at least 128 MB??? :twisted:
@trendstyle,
Sell the device.
Anyways, what is it that the 64MB RAM of the JJ does not permit you to do? Why on earth would you need 128MB of RAM? I multi-task extensively with the device and yet face no memory errors. Are you trying to run Photoshop or something like that on your device?
As another forum member has rightly pointed out, what on earth would you need 256Mb RAM for??? It wouldn't even last those 93 seconds!!!
Word of advice to other people who want to crib about the device. Before you start getting all nutty about spending this much and that much on a device, do a thorough research or wait for some reviews. You will save yourself and others the agony and disappointment.
My 0.002.
I entirely agree with Universaldoc.
While listening to the media player and running two processor and memory intensive applications Planmaker and TextMaker simultaneously I still have 10MB of RAM to spare. Why do I need more RAM. I am to use my JJ practically and not to see what amount of applications I need to open simultaneously to kill the JJ. More RAM is technically possible. But do I need it at the expense of battery life. A big "NO" for me at least.
Regards
Do you?
10 Mb are enough?
There are some games, that requires 15 MB of free RAM!!
And in a super top device, this should be acceptable???

A new rom that came with 256mb memory with it, now there's something....
The universal is a good device and memory is fine on it you can have loads of apps running and it still runs faultlessly. This is not a lap top, if you ned one of those buy one nor is this a mobile it's a great device that tries to accomodate both, sure it could have more memory but then you'd be *****ing that " it's primarily a phone, why is the battery life so bad, it runs out half way through the day and i miss loads of important calls"

I know people are now used to computing with 3Ghz AMD64's with 1Gig RAM, and 100's of Gigs of HD space, but let's be realistic here, for a device of it's size, it's fantastic.
Given 128Mb RAM, I'm sure some people would only move on to bemoaning the fact that it 'only' runs at 520Mhz, it 'only' has 128Mb Rom, it 'only' has 802.11b, it's 'only' got 1.3 megapixels, etc, etc, etc.
The JasJar is not perfect, and there's a thread in this forum where people are already posting their JasJar 2 wishlists, but in my personal opinion (and I'm sure many agree), it's currently the best PDA/Phone available, it has near flawless performance for my purposes, and I for one am more than happy with it.

In my point of view I assume 64 RAM are enough but if we had a big DOC storage well lets say about 256 MB this could be something for us, but the facts and the sad parts, which it's the 128MB of DOC :evil: !!!

Shift dissasembly and SSD installation.

I am having thoughts of installing a ssd drive inside htc shift. Is this possible? Has anybody tried it or dissasembly htc shift?
Thanks,
Lefteris
i dont know that im brave enuf to kill my warranty. If the drives are the same size and same power consumption and have the same mounting points then it should be easy.
That's a lot of ifs...
And if you look in Vista at the Experience index, you can see that the HD is fast enough
Okay, SSD is always a lot faster.
I forgot the big if,
IF you can afford one the proper size
If someone has very large juevos they could crack their shift open and take some pictures!!!
doh, daniel u should of done that before replacing it!!!!!
There are internal pics of the Shift on the FCC site.
https://fjallfoss.fcc.gov/oetcf/eas...omFrame=N&application_id=542917&fcc_id='NM8CL'
good to know we can upgrade the harddrive very easily then
and the ram oh goody 2 gig chip
Those are very easy upgrades, does anyone know the part #s for the existing items?
We need a ghost of a prestine box, make sure one of the senior guys when they get their box to ghost is right away.
Well one thing for sure an extra gigabyte of ram would help.
But is does seems we need a very specific module to replace the RAM.
Any ideas where to buy such a module?
According to the FCC pictures the ram module is:
Qimonda
qty 8 of HYB18T1G160BFL-5 / 3VV08956 (also has 0724 and B on the chips)
on a double sided chip

The problems I see is that Qimonda is a producer of RAM chips, not a retailer/seller of modules.
And second they only list 1GB sets.
Third, where can we get our paws on a 2GB module?
Ouch,
I just located some 2GB DDR2 microDIMM RAM at 500 USD, the 1GB chips are 180 USD.
also we have to find out if the vista bios supports 2 GB DDR microDIMM, the bios they are running is very weak, i suppose we would have to get a new one of those too :/

The MSD-PATA3018-032-ZIF1 is an 8mm drive (height), so no, it won't fit. You want the MSD-PATA3018-032-ZIF2 which is 5mm in height.

If someone can recommend any 2.5" SSD with 44-pin IDE or 1.8" with ZIF just let me know. 32 GB is just enough. I had Samsung 1.8" with 50-pin IDE, but it was 16 GB (around 15GB actually), so 50-pin IDE will work too.
The only difference betweem the ZIF1 and ZIF2 is the height. The ZIF2 (5mm) is being produced for regular orders by Mtron, so you will find this easily available (http://rocketdisk.com/index.php?cPath=15) but the ZIF1 (8mm) is only being produced for OEMs and other special situations.
There is no reason for it to be so cheap, other than good value
The performance is really awesome & as you have probably seen on notebookreview.com there are lots of happy customers!! ---- end quote

326MB of RAM?

Just got a Samsung Vibrant.
I noticed the phone says I only have 326MB of total RAM. I thought this phone was suppose to have 512MB of RAM? Is 326MB normal or did I get an odd phone?
No that's right. It's all the kernel will allow us to use. Even with the unofficial froyo roms out, we only get 341mb.
Friends don't let friends flash drunk...
Cool. Thank you for the information.

I would say it is more like on your PC. You may have 4 GB installed, but when you look at it it will tell you you have only access to 3.5 GB because other hardware is using the memory, like a shared GPU etc.

I'm getting tired of people making these retarded f****ng comparisons. Hard Drive capacities go down due to formating. Also, a 1 byte file takes up the smallest allocation unit on the drive, so space is wasted there as well. Better file systems are better about it, but unless you're writing raw data to the hard drive there's no way to avoid formatting it and losing space or writing data to it and losing space due to allocation boundaries. I've never heard of anyone Formatting RAM, have you? If the smallest allocation unit on the HDD is 4KB, then a 1Byte file will really take up 4KB on the drive's FS.
RAM is totally different. If there is 512 RAM there's 512 RAM. The only time you will see less than your amount of RAM on a computer is if the computer is allocatting a certain amount of RAM for use by an integrated graphics card (or something else).
Problem with our phones is that they're set up like the latter.
We don't have 512 RAM. We never have, and we never will. We haev 340'ish and the rest is GPU RAM. You're never going to run general applications on that RAM.
Oh. I had edited my reply because I had assumed I found my answer from this...
developer.android.com/sdk/android-2.2-highlights.html
"HIGHMEM support for RAM >256MB"
I had assumed that mean the official Froyo when we got it would have 512MB available.
So I guess I misunderstood their meaning there. So the 326MB is pretty much the max my applications will have to work with on this phone?
I guess I'm puzzled because I was in T-Mobile a couple days ago and I was going back and forth between getting this Vibrant and the MyTouch 4G. The MyTouch 4G advertises 768MB of RAM, while the Vibrant advertises 512MB of RAM.
So now I'm back to my original confusion. Why would HTC put 768MB of RAM in the MyTouch 4G if Android can't even use 512MB? *confused*
Ya'll compared it to the Windows XP limitation with only seeing 3.2-ish GB of RAM. But Dell doesn't install 8GB of RAM in Windows XP computers either. I guess I could maybe understand the 512MB phones if some of the memory is going towards video. But the 768MB phone doesn't make sense then.
This is my first Android device, so I'm still trying to figure out these things. Sorry for the dumb questions.

First of all. There are no dumb question. Second. Android uses all of the RAM. But as the phone reserves memory for hardware and other system essential services, you will only be able to use a certain amount of the memory. In this case around 345 out of the 512. The rest is put away so that the OS can run stable etc.
So for the MyTouch 4G it says that there is 768 MB installed, but you won't see all of that. The phone will reserve certain amount for it's hardware and you will never be able to free it unless you know how to change the kernel.
Hope this clears any confusion up.

for xp, the memory limitation is due to 32bit memory addressing. 32bits can address a theoretical 4gb, however due to also addressing gpu memory and probably some other reasons xp can't address the entire 4gb and so you see 3.xGB.
i can't really speak to android or the vibrant, but i'm guessing (like others have said) we are losing some of our ram in a share with the gpu.
I think most people are missing the issue here.
The phones are advertised as having 512 MB RAM.
When you buy a computer, and it says 512, it comes with 512 (only exception is the one I stated - integrated graphics cards sharing system RAM - but that is usually listed on the Computer Spec sheet).
So, when they get a phone and it says 512 MB RAM, they expect for there to be 512 Application-accessible RAM on the device.
HTC adds more RAM to put the user closer to the advertised specs. Most other manufacturers do not.
So users end up with 326 MB RAM wondering if they got what they paid for.
Which... they really didn't if you use you common sense, but companies will always use technicalities tand semantics o defend their decisions and/or actions.

I completely agree with you. In fact some of us in xda have discovered that sgs indeed has less than 512MB of RAM. We are still somehow trying to defend Samsung by say Galaxy TAB has more RAM (when Samsung advertise 512MB only for TAB)!
On a side note - Hard Drive capacity is measured in millions of bytes hence 500,000millionbytes
will be around 465GB only (unformated)!

I doubt ~170 mb is being allocated for the radio and for hardware addressing space. It's my opinion that the phone actually only comes with 384mb ram.

Many do list that but what makes the drives smaller is formatting. The raw size is what it is, but the formatted capacity is much less. You can ser this on sf cards easily. Format it as fat32 then ntfs, and the end (formatted) capacities will be different. Then play with allocation sizes as well ;p
If you have hordes of small files it can really eat inyo the space on ut hard drive, as well, since a file can only be as small as the smallest cluster size in the filesystem.
Even if they made the drive 1024mb x however many gb they say it is, that will be instantly cut fown tje minute you format a fs onto the drive. There is also space the fs reserves for system use, as well. Mft and such.

He's right hardware addrrssimg shouldn't need that much, and graphics in a phone shouldn't need that much either. Maybe so,eone should sue Samsumg for false advertisement and see what they say.

You can "no." all you want, but unless you have proof to the contrary, I'm going to stick with my OPINION that the phone has 384mb.
There's no way in hell the Radio, hardware addressing space and/or GPU frame buffer use 170-180mb of the ram.

I agree just checked and vibrant shows similar ram to htc aria, which has 384mb ram stock.

There is a thread in the i9k forum that details the amounts of ram reserved in the kernel source. Just about every feature on the phone has dedicated ram, weather or not it's currently in use. That plus what the kernel shows as available adds up to 512mb. It's stupid, but that's how it is. Poor and lazy software engineering, IMO. Unfortunately, doing the allocation in a sane way and having it work in android properly is very difficult without all of the source, which we will probably never have.
It's not really any better with other manufacturers. They all do it. I think they ought to be required to disclose user available ram amounts, but nobody cares what I think.

I'm getting tired of people making these retarded f****ng comparisons. Hard Drive capacities go down due to formating. Also, a 1 byte file takes up the smallest allocation unit on the drive, so space is wasted there as well. Better file systems are better about it, but unless you're writing raw data to the hard drive there's no way to avoid formatting it and losing space or writing data to it and losing space due to allocation boundaries. I've never heard of anyone Formatting RAM, have you? If the smallest allocation unit on the HDD is 4KB, then a 1Byte file will really take up 4KB on the drive's FS.
RAM is totally different. If there is 512 RAM there's 512 RAM. The only time you will see less than your amount of RAM on a computer is if the computer is allocatting a certain amount of RAM for use by an integrated graphics card (or something else).
Problem with our phones is that they're set up like the latter.
We don't have 512 RAM. We never have, and we never will. We haev 340'ish and the rest is GPU RAM. You're never going to run general applications on that RAM.

I had 326 RAM .After installation of FROYO 2.2,my Galaxy can see only 304 RAm.Why?I expected to get more RAM with FROYO 2.2 Why did this happened?

[Q] Lenovo TPT HDD and RAM memory lower than in spec

Hi,
I bought a Lenovo Thinkpad tabled with memory specifications of 1GB RAM and 16GB HDD. All nice, until I go in Settings and check at settings/applications/storage use/running and all which show a disappointing values of total memory ~550MB RAM (almost half...) and ~12GB (almost 25% less...).
For HDD, I can not accept that the rest of 4GB are hidden because are used by Android 3.1 or used by file system format. Even so, Lenovo should be honest and declare total memory against available memory even is "eaten" by various reasons.
For RAM, I can not find any explanation why I see only half.
Q1-Can somebody explain me if tablet is faulty or has a kind of manufacturing issue ?
Q2-Can somebody to check if his tablet has the same memory discrepancies versus manufacturer specifications ?
Thanks!
All tablet's have this "cheaty" way of listing specs. But if you buy a laptop and it says 200gb. You can be pretty sure that windows 7 or what ever is installed is taking up space. The same applies to RAM. While the system may come with 4gb ram, the system has "eaten" som of it.
So, I don't really see the complaint here?

The specs will never match the actual available memory since there is always space allocated to system whether it be ram or hdd

It's likely that the other half is being reserved as video memory.
Hi,
Thanks for reply. I've done a check on other tablets and they show the same lower memory than spec, except Asus 501 I think with ICS 4.
However, I think it should be specified total phisical memory and available memory.

Total available ram will be different and much less than the specs on any Android or mobile device. The system uses memory to load OS and for graphics.
Also the memory space will be less formatted and with all the system apps.
Just like a formatted hard drive or ssd is less than spec.
I do not know why people still complain about these things it is pretty ignorant. Have you ever owned a computer, tablet or cell phone before?

New galaxy s10 plus help needed..

So I recently bought a new s10 plus but I made a post about it already but I haven't received the phone so I didn't know anything about it, today I received the phone and checked the ram and its only 8GB is this normal or is it suppose to be like 12 or 10 GB ram? (my phone is 12 GB ram and 1 TB variant). Also, is the screen supposed to flicker a lot when it opens up the camera because mine do?
Download Device Info HW from the play.store and check the specs
Anything more than 6 gigs of RAM on an Android phone is nothing but a marketing gimmick. The vast majority of people don't need more than 6 gigs of RAM on a laptop--according to Microsoft the minimum RAM requirement to run Windows 10 is 1GB which is stretching it but 6GB is more than enough to provide an extremely smooth experience for anyone who isn't a power user. With that in mind what practical purpose could having 8GB or 12GB of RAM on an Android phone possibly serve?
The expanding RAM numbers were a gimmick to convince the gullible that they needed to purchase expensive new phones--these are the same kind of people who don't question why they need a higher resolution display on a phone with a 10" display than on a 55" television screen.
Now that more RAM and higher resolution are the norm the latest gimmick is smartphone displays with higher refresh rates. Most people won't actually be able to see any difference but that hardly matters if it sells phones.

So you already stated you have purchased a 1TB 12GB ram s10.. and you received an 8GB ram s10? Where did you buy it from? I would bring it back since it may be the wrong one or it may be fake depending where you purchased it from.
How much did you pay for the device?

It is possible the wrong product got delivered to you, If your order correctly states that your device should be a 12 GB variant, you need to do a RMA.
Just to be sure update your device, for checking your RAM, go to settings -> Device Care -> Memory. At the top it should list, there should a be a bar and just under it your used memory/total memory.
For checking storage, go to settings -> Device Care -> Storage. At the top it should list, there should a be a bar and just under it your used storage/total storage.
If either of these don't match your order, please check with the seller, you should only get what you paid for.
As for the screen flicker, it really shouldn't happen, on my device opening the camera app is a rather smooth animation.

Dude, what is your problem? OP asked for verifying the specs of his device and not a lecture on what is the appropirate amount of RAM according to you! Did you even read his question?

Hi sir, I wasn't very clear , sorry.. i currently have 8.5 GB ram available with no apps opened and seller confirmed it was original although I am still afraid coz I bought it not from official shop. In us dollar it's about 800 usd but in my country it's Rm 3000.. I am not sure its suppose to have 12 GB of ram if I have no apps opened or is it normal to have 8.5 gb of ram bcoz it might eat some ram for the system to run so I opened this thread.
Android is designed to fill most of the RAM at all times. In simple terms, empty RAM is wasted RAM.
As you start using apps, Android will keep your most commonly used apps in RAM, so that they launch quickly each timeyou open them or switch between them.
