I thought about those 2 free ram slots..
and i even found a distributer of "infineon" near me !
i think i'll take my JJ to some 1 to solder it,
and another Q is:
is it possible to buy a faster intel proccesor and replace the existing one?
will there be any problems with that?
Technical info and opinion
About RAM:
If you buy the same specification ram and have a company microsolder them into your device, great! It should be fairly straightforward. Please take measurements of your device's performance, battery life, observations, and system info before and after updating and post back to let us all know how it goes.
About Processor:
Windows Mobile 5 seems to be built to automagically recognise the parameters of the Intel XScale CPU in it, meaning that switching the CPU to another of the same family should not cause problems. Replacing it would be an impressive feat to accomplish physically, so again get back to us all on this. You could get up to 800Mhz! Check out Intel's Xscale roadmap at http://download.intel.com/design/embedded/downloads/30610501.pdf
Pocket Hack Master is a utility which allows users to overclock their HTC Universal; see http://forum.xda-developers.com/vie...&postdays=0&postorder=asc&highlight=overclock
My personal observation:
I'd be reluctant to try microsoldring surface-mount ram chips to my new Universal (has to be done professionally). My 64MB work fine, not to mention another two chips would potentially add 1.4watts (0.7watts each) of battery drain and heat power dissipation to my device. I've only got 1600mAh and tend to travel (no-recharge).
I urge other users to mod their devices in the pursuit of science and performance; both truely noble causes. Example, more ram would ease the running of Linux on this device. Please continue working towards a Linux port for Windows Mobile devices!
now comes another moding question:
is it possible to buy a better battery?
or is the one that comed with it - "standard" and unchangeable?
10x,
P.S
P.S-
Which proccessor would you reccomend on that will not drain my batt?
(please specify exact model so i'll know what to ask for)
as for Ram: Is it possible to replace to existing ram with a higher one?
or just upgrading by adding 2 more (exactly the same) ram chips? if it id indeed possible -
again, please write me what model do i need (that would drain my batt life).
Use this link for reference:
www.infineon.com//upload/Document/Memory Products/Brochures/Mobile RAM/Mobile-RAM_2004-03.pdf
10x again,
ok, i just got off the phone with
some 1 who works with intel,
asked him the question and he says - right now 520 MHZ is fastests,
(it also says it here)
http://www.intel.com/design/embeddedpca/applicationsprocessors/302302.htm
and soon will come out a new proccessor but even then, you wont be able to just do a simple switch between them.
it'll have to be acompanied by a software update ect....
but hey, i wont mind updating just my ram :lol:
,im sure i read that there will be multi tasking in the future, now the problem i have is im still looking to get a phone i.e. dvp., but its only got 256mb ram, now is this going to play a big part in which phone to get because of multi tasking.

That was posted in October, more recent news actually show on the device as having 256MB
Personally, I would get a different device due to this - it may not actually make a difference in terms of multitasking, but we just don't know until multitasking is available to developers.
Thing is, developers are allowed to us 90MB for any single app (or game), but this only applies to devices with 256MB RAM. That means that multitasking has not been taken into consideration at all when writing the marketplace specs as I doubt you'll be able to fit 2 x 90MB apps in memory at once (on a 256MB device the total available amount is something like 220MB - as parts are reserved for GPU etc). That said, there is no rule saying that if a device has 512MB the app can or cannot us 256+90 (ie. 346MB) so...
Of course, most apps do not use 90MB so it's not a huge problem. But given the choice between a Dell or Samsung I'd go for a Samsung any day of the week (which is also what I did).
depending on what you want to do/use cases, if you want multitasking ability, take a look at the nokia n900
cheers
I was glancing at some screenshots of the Galaxy Nexus/GNex/Gex/Whatever, and noticed an issue/feature which is not unique to the Nexus.
The quote RAM figures for the device and the RAM total in the "Running" section of applications never match (in the massive sample of Android handsets I've seen - 3).
HTC Desire: Quoted RAM - 576MB. RAM total in "Running" section - 374MB. 65%
Galaxy S II: 1GB (1024MB). 693MB. 68%.
Galaxy Nexus: 1GB. 631MB (in screenshot I saw). 62%
I'm not actually calling this a problem, I'm just wondering what is the reason for this difference. Is the "Running" apps section simply RAM allocated for apps and the rest of the RAM is for the OS? Are the OEMs lying to us while smoking fat cigars by their swimming pools?
I'm sure there's a very simple reason for this. I just don't know it.
Just like the devices total memory is 16 gb and 13.xx is actually to be played with. These things often get 'rounded up' quite often in the world of cars the manufactor claim a certain horse power and its rounded to nearest 50 or 100. Such is life in this modern age I'm afraid and unless some kind of consume4 rights group tries to do anything about this the current trend of manufactoers and ceo 's bull sh*tting to us is likely to continue.
Of course I'd like to be wrong and say that the other 300+MB are dedicated to the 'system' but I can't promice I'm afraid.

I dont think it's that easy in this example though.. when talking about storage size one actual GB is 1024 MB but when it says 16GB on the box the manufacturers and retailers actually mean 16000MB devide this 16000 by 1024 and you get the real useable storage size, 15.625GB in this case. Talking about RAM on the other hand they tend to go by the full size GB when typing it out for you, 1GB is 1024MB of RAM, so.. where does that lost RAM go? I dont know! Someone with deeper knowledge want to explain further?

Maybe the 'system' really does use that much then although bear in mind sence and touchwiz are bound to use more. Hopefully on the actual retail release software will be more optimized and we get some ram back.

The GPU shares memory and reserves a huge chunk of the ram for itself.
The rest I can't explain correctly (if it's correct at all) but it's reserved for the os and can't be addressed by apps.
These reports only show the part that's addressable by apps.

So this is to ensure the OS has enough ram and flows nicely and keeping everything lag free and super quick. Good news

Nice one.
As Tjotte said, I know that when it comes to storage, manufacturers normally quote gigabytes as multiples of 1000MB (I call this lying but what the heck). Then you add another small percentage for BIOS and you have a storage device with about 90%+ of what you thought it was going to be.
But around a third off the quoted figure??? That's more likely system allocation rather than a blatant lie.
Which now leads me to think... PC GPUs have their own RAM completely separate to system RAM. Apart from cache, I'm guess the mobile SoC's don't have specific RAM. Hmmmmm..... A quick peak at AnandTech at the Kal-El write-up tells me they don't. Bummer.
I think some of its used for caching as well. If you open task manager in Windows, you'll often see how the available RAM is far less than what would be expected if you take total RAM and subtract the RAM used by currently open apps (both system and user). It could be that some of RAM is essentially pre-fetching or caching apps, both user apps as well as system apps (such as Dialler, Framework components, GoogleSync etc) which notably make launching everything faster. And some of it is definitely used by the GPU as well similar to the integrated graphics on pc's, and this is probably dynamic as well, which can explain why available RAM does fluctuate within the same phone in similar conditions.
Internal storage is the Gb vs GB bit vs byte issue plus partitioning, a free hundred MB as /system, maybe other partitions for other things such as user data etc.
As far as the ram, some for the gpu, the os will use some, some will be used as cache which can be dropped if needed, but in the end the device still has more free ram than some phones have in total.

Disk storage manufacturers calculate in base-10 and memory manufacturers in base-2. If they say a device has 1GB of RAM, it is 1024MB, not 1000MB. Same goes for flash memory. The Nexus has 16GB of flash, 2.5GB appear to be reserved for system.
Anyone who wants to understand the difference between base-10 decimal SI units, JEDEC units for RAM sizes, base-2 binary IEC units, and the confusion 1000 vs. 1024 creates should check out Wikipedia's article on the topic, as it pretty much covers everything... including things like how storage device sizes and network speeds are measured, consumer confusion, and even lawsuits.

That's all well and good but it's totally irrelevant when it comes to the 1 GB ram in this phone. It has 1024 MB ram, as stated. However, some of it is reserved for parts of the hardware like the GPU, the radio, video encoding/decoding etc. This is the same for all Android phones. Anyone that wants to see it can check that allocation in the source. Brian Swetland from Google has already described the motivation for this and the specific sizes used for different components for the Nexus One.

Agreed that it is irrelevant and the device definitely has 1024 MB of RAM. I was going a bit off-topic in an attempt to defer any further off-topic comments on that subject by directing people to an alternative source for that information rather than discussing it in this thread, which is about the Galaxy Nexus's RAM.
Your post is probably the most useful and informative so far in this thread. It does have 1024 MB, used for various purposes as needed, and there's really not much else to say.
It is hardware accelerated and to my knowledge the sgx540 doesnt have discrete ram so that factors into the equation. I wouldnt be sjrprised if the os allocated 64-128mb ram for the gpu.
I invented cyberspace. You're trespassing.
RAM Division
1.HW Drivers(screen, gpu, audio, etc)
2.OS Services & Shared Memory
3.Cached Services/processes
4.Active Apps

Oh, I see. Fair enough. Actually I wrote my post based on the assumption that your post was the first post. I later realized that was not the case so I just quoted your post to make it clear which post I was referring to.
-Most of the times a part is reserved for the gpu.
-Android will reserve more ram when there is more ram to optimize performence.
-Abdroid get more and more features wich use more ram.
-Active apps wil be kept in ram when possible.
-Applications get also more complexed.
-Android gets build differently when there are higher hardware standards. Compare for example windows 7 with windows xp. Windows 7 uses a lot more ram because of several cahcing optimizations for example.
Could be buffers too.
e.g if you check free memory on a linux system a large amount is used by buffers but is actually useable if needed.
It's definately not "rounding up" as 30%+ is a long way from the kind of rounding up manufacturers of storage do.

This is actually very useful for people that don't understand the differences. And there are many that don't.
They had to cut back on the RAM because they paid too much for Matias, since the boxes were already printed with 1GEEBEE noted, they're now trying to pass it off and hope nobody notices.
Lately there has been a lot of talk about RAM. People coming from CM7 noticed the low free RAM on CM10 and the overall laginess compared to the first complain.
Many have explained in numerous posts how actually RAM works in Android Jelly Bean. Short deal, Used RAM to cache apps is useful for multitasking. Some of us don't multitask that much but some do. On some busy days on the road i use my phone as my main "computer". And i toggle between phone, messaging, email, maps, browser. I admit after a day it gets tired because the Defy is old now but it works (on CM10), not stellar but it works.
One problem i see is although apps get cached when a larger one needs to be opened it takes some time before it starts freeing space.
Next year i will buy a new smartphone. It's been 2 years for mine and it's journey will be completed. So i was looking for what options do i have.
In Europe SGS3 has "only" 1GB RAM from which video takes ~250 mb leaving(no?) leaving ~750mb for system&apss,(~400 mb free on stock 4.0.4- I saw on a friend's device) fact i consider not fair compared to it;s US sibling. HTC OneX and Galaxy Nexus both suck in the battery department and there are other specs i consider more important than RAM.
I am "in love" with the Nokia Lumia 920 design and screen (Ohh, that screen.... ) but not the OS, i like the Galaxy note 5'' pen and productivity features.
So today i looked at the LG Optimus G presentation. It has 2GB RAM and top dog Snapdragon S4 Pro chipset with Quad Krait . It's really a sweet device, great screen. The funny part is that the review units after the presentation had a RAM widget on desktop. So how much free RAM on a stock version? (although probably there were some apps opened already) - just 800 Mb.

That means more RAM is used than and old Windows XP Dell i am typing now on ( 650 MB used with Firefox, Skype, Dropbox and a few other processes open). It's clear that they don't handle RAM the same way so you must reconsider this comparison.
Android has come a long way and it will only get better but RAM is not the most important thing to take into consideration. I found that my constant look for keeping RAM free on my phone with different methods only wasted time i could have spent doing something meaningful.
And 1GB of RAM is still enough while 2 GB RAM feels like a maximum we will never see broken for quite a while.
just wondering since lg nexus got 2gb ram and our gnex got 1gb.and most ram remains free..ao wats the point of giving 2gb ram??
Twice the RAM is the point.
future proofing. And as soon as another phone comes out with more ram, you get the crybabies to say "why does our phone only have 1gb of ram if it is newer than phones with 2gb?"
i think 2gb ram is quite unnecessary..it is quite tough to use up 1gb ram as android is very good at multi tasking.
the reason it is good at multitasking is because it is constantly closing apps, this action can be alleviated a bit with extra ram thus creating a more fluid user experience. Also it is a competitive market, this gives google something to brag about. Also remember these are used more as micro-tablets, pushing to 2gb opens doors to better games. It is much better to have unused ram than to have not enough. I personally would rather get a phone and in 6 months when a cool game comes out i know my phone can play it as opposed to struggling.
More RAM also means more internet browser tabs that can be switched around without having to reload them. Overall it results in better user experience.

Exactly for the reasons listed above. More multitasking at every level
Isn't 48K RAM plenty? My Apple ][+ ran fine with that much back in 1982. Sheesh.
i could also play modern combat 3 on my sgs i9000 lag free.. i think 1gb is enough for me
It's the same evolution as was seen in the PC market from the 90's to present. My first computer only had 640kB memory, then came 2 MB, then 4 MB and so on.
It might not be needed today to have that much RAM, but games and applications get more advanced and to be able to keep a good multitasking environment operational in the future you will need more RAM.
I welcome the change in RAM size to make the phone usable in the future as well.
It's like saying we don't need quad core processor... Sure, you don't need it now, but it's good to have and your phone can handle more advanced programs than duel core.
Also I have hard time keeping my apps that I like in memory, even if I have 1GB, so I'm personally looking forward to 2GB
I won't be happy until 8GB of RAM is the norm. That's the point at which I'll be running a Windows 8 virtual machine on top of Android just to be sardonic.
1gb is probably fine for now but I can see it being useful in a year or so. I think I am going to stick with the galaxy nexus until next years nexus but I am eagerly waiting the nexus 4 hands on reviews.

Better multitasking and faster switching between apps. Personally I'd rather have as much RAM as possible without causing too much of an increase on the price of the phone. Getting slowdowns from running out of RAM is annoying and except for the price I don't really see any downsides for having more. One can always buy a lower spec phone if they think that 2Gb is too much.
Also as others have said having more RAM makes the phone a bit more future proof. For example my previous phone (HTC Desire) has only 576Mb RAM which certainly doesn't make the experience any more pleasant when using current Jelly Bean ROMs. And it's still "only" 2 years old phone...
