Ram decreased from 288mb to 256mb?

Hi Guys,
I'm totally puzzled with this. Just bought the touch pro 2 with the Device Information in Windows Mobile 6.1 showing with 256mb ram. I supposed the official spec from HTC comes with 288mb ram installed???
And one more surprising thing I've found is that it comes with FM Radio pre-installed on the device. But I thought there's official news again from HTC that they decided to remove FM radio??
Now I'm puzzled by this...
Anyone have the same problem?

yes, mine also reports 256MB

UPDATE - wrote to HTC and they replied saying this is a software bug and they may release a patch for this next month.

yes, i have the same problem. displays as 256MB

Same for me, should be a reason for it i guess..

i was lucky enough to have the first shipment in uk unbranded unlocked and mine even says 256 ram so this is a bug from the start.

Yeah I wonder why. Anyone asked HTC?

Its the Diamond Qualcomm aliens that eat ram!
Seriously though, isnt 32mb reserved for graphics?

There are 2 RAM ICs on HD/Blackstone; 256Mb is accessible in WM, 32Mb is accessible in radio. Latter 32Mb could be used for video acceleration too, don't know. Supposedly the same is true for Rhodium...

see my reply above

hi guys (excuse my english) ,
I have the same problem with memory - it says 256mb
But more disturbing thing for me is that when entry
settings-all settings-system-memory it says only 188mb memory!!
Is it same with you , and if it is why is that?

i mean it seams like my devise is working only with 188 mb RAM .
I see that in notifications bar and also in setting in memory tab.
Is it Normal?

Mine says that too. But that is program memory which you can use to install programs not ram (random access memory), it should be like this.

Hi Guys,
HTC just released new ROM to fix this problem.
http://www.htc.com/hk-en/SupportViewNews.aspx?dl_id=612&news_id=199

Just Check the site above but when I entered my serial, it is not suitable to my device...

I guess it is only for "HK" reqion...doesn't work for me too with same error
"Sorry, this software download is not suitable for your device."

The link to the ROM update on HTC/HK can only be downloaded using serial numbers of devices distributed officially, sold and bought in Hong Kong only. The English update carries the file name "RUU_Rhodium_hTC_Asia_HK_WWE_1.19.721.3_Radio_Rhodium_3.44.25.27_Signed_Ship.exe" so it looks like it's targeted for HK units only.
For devices bought from other locations, you need to check for ROM update through the HTC support page for your region.

i'm not exactly clear on this, does it just display the RAM incorrectly ?? or does it actually not detect the RAM ie only 256mb is available for use
can anyone clarify ??

is there a way to find out which country is ROM from in my Touch Pro 2?

I'm glad HTC has posted a ROM fix for HK users & soon it will be available to worldwide users. Anyway I come from singapore so last but not least we shall see what other fixes are contained in this new ROM.
Cheers everyone

It's displayed incorrectly.

is it better to move all apps/system/cache/data to sd-ext?

hi,
i was moving all apps/system/data/cache files to ext2 partition of my old device (samsung spica i5700) because of it is too slow. is it better to do it again on my desire z or not? or is only moving apps enough to get better speed?

Uh not an expert but I don't think its needed. Definitely doesn't make the phone faster. All that only seem needed on old phones.

a2sd is entirely useless on newer android offerings.
what were the reasons for a2sd's inception?
- not enough ram (swap, compcache)
- not enough internal memory (move apps to ext partition)
well, now that we have enough ram and enough internal memory, anyone who tells you you'll benefit from utilizing the sd card as ram/additional storage is flat out wrong. it's always preferable to keep things simple... a2sd is another complication in the system and at this point will only do more harm than good.
still boggles my mind that some devs are wrapping up A2SD into their roms... and I've never received an answer from any of them regarding how it is useful.

The previous poster is correct. I had to use A2D on my T-Mobile G1 because I kept on running out of internal storage. However on my T-Mobile G2 I haven't had any issues due to the large internal storage.
If you are running out of space, move the apps that don't run constantly in the background or use often. Or just get rid of the apps you don't use anymore.

I cannot remember from where but I read to not to use task killer applications. it said those types of programmes force to close applications and android system forces to open them again; and android is already clever to manage applications which is necessary and not. is this true?

super tiny picture.

All the task killer app does is take up more memory and drain your battery. Android has gotten better since I'd say 2.2 at reclaiming memory taken up by applications when you are no longer using them. Also it would help if you uploaded a larger picture as it's impossible to see what your talking about.

'Android OS' is your ROM image, your OS, system, built-in apps, etc.. The only reason why its close to full is because you're running Sense, which is a HUGE ROM that takes up a lot of your OS space. (For example, running CM7 (AOSP based) I have 267mb free on my System ROM space).
'Internal data' is where your apps are being installed. That's your free space to install apps on built-into the phone. Unless that's full or critically low, don't worry about it.

I know sense based roms are slower than aosp roms. will second bar increase or decrease by installing apps or not?

The bar is just how much of the 'System' space is getting taken up by your ROM. Just let it be. You're not going to make Sense any faster by messing with the System partition or the Internal partition. They're both internal storage, just being allotted differently to each side.
I'm not expressing how Sense is slower than AOSP, I'm expressing that Sense is LARGE, like in file size. There's a ton of extra mb of data in Sense that all takes up space inside the internal storage. Android is doing its job here, its putting the ROM in the System partition, the apps in the Internal storage, and larger apps on SDcard storage (the latter of which is the only one you can/should change by moving to internal storage).
The apps you download from the Market are being put on 'Internal' (or SD), not in 'System'.

Why are ROM sizes not listed??

We see all the specs a device has except ROM size and ROM is even more important than RAM, CPU which are always listed on devices. Lucky for me my HD7 ROM was listed but you don't get to see them on the lumias, titans etc . All that is listed is internal, RAM, CPU. No ROM and GPU. Meanwhile we all know phones are not updated based on ROM,something most people don't know and it's a very important spec which is not listed. You get to see rom size at settings on most android phones but not windows phones and as a windows phone user and lover, I'm concerned. How can we know our ROM sizes??

What does it matter, if I may ask? As long, as it fits updates, there is no reason for you to need to view it . GPU is tied to the CPU itself pretty much.

It matters because it's now becoming clearer that phones get major OS updates due to their ROM size. In the android world, most pho e will nt get the ICS because the ICS package is way bigger than their ROM sizes.So i will rather get a pone with a bigger ROM just to assure myself of major OS updates can can only do this if the ROM size is listed.

WP is not android, MS has be doing OS's alot longer than google, both mobile and PC, they know what they are doing. ROM size doesn't and shouldn't mean anything to the end user.

does the updates go straight to ROM? i don't think so, they store first on the memory of the phone, therefore stays in some updates "you must have some storage memory free to update..."

The update gets downloaded to a temporary folder and then it gets installed to ROM.

thats what i said just another words so why does it matter which size the ROM is... the only what really matters is RAM, because if the want to try to port win8 to 512mb of RAM, thats really tight for all apps, think just of your pc now, i have the consumer preview of windows 8 and in normal use, on start it uses over 500mb of RAM. and with 2gb of RAM i am not able to use it seamlessly like windows phone 7

i whish we all get wp8 update on all of our wp7 handsets. i relly whish that but i look from an other site to it. from the site if it is possible or not... and i think its not possible to get the same experience now on our 1gen device like on a arm win8 tablet...

ROM is a paramount component. I own a HTC Amaze 4G (pretty high end) which has got 2.5 GB of ROM size and stock firmware. By the end of the day (I mean with loads of apps moved to SD), I still face the problem of "insufficient storage available" crap and after a total wipe out using cache cleaner+, I am left with about 250 MB of ROM which is pathetic.
In 2011, ROM size is still the bottleneck in smartphones. Good job phone designers, you had our money and messed up with our brain. I wonder which smartphones out there are having at least >5 GB of ROM?

how do you mean insufficient storage available? rom is not and read/write memory, its just and READ memory. so it can not be used to store you personal data or anything similar... do you think maybe RAM? you device has 1gb RAM, and if your apps working in the background that beside the UI and the whole system you have no more RAM available that can happen. but insufficient rom? ROm is only used to "store" your system, but the data collected in the system such as phone numbers, pictures, cache are in the storage memory (external sd card) or (internal memory as it is internal "hidden" sd card) and not in the ROM.

i think that is phone memory of all 476mb or 475mb. and i think that is RAM, not ROM. everybody say here ROM (READ only memory) for RAM (Random access memory) the ROM has only the system, the bootloader and so on, the RAM is used for app cache and other things. same as a PC RAM, it stores your open or last used programs od dokuments. and i have an htc 7 pro too. and it has 476mb of RAM, and not ROM. the ROM in the htc 7 pro is 512mb.

[MOD][for KT kernel TW] Turbo ZRAM 4X swaps!

>>> Welcome to Turbo ZRAM!! turbo ZRAM Script V1.2 <<<
===============================
What is Turbo ZRAM?
It is a unique performance mod which sets up 4 parallel zram swaps for kernels with the zram module.The swaps are set to run at the same priority so the Linux kernel is able to multi-thread the swap process on our powerful quad core devices. Zram runs super fast with no lag
What does zram do in the first place?
Zram is a virtual disk which resides in RAM itself. App data sitting in the memory is compressed while it is not in use to 1/3 its original size. Effectively your phone has more memory!
Regular single-swap zram can lag considerably while it compresses/decompresses the swap data. Turbo zram solves this issue
Why would we need zram on a device with 2GB of RAM?
Well it depends on what you want to do with your device but why wouldn't you want to effectively create more memory out of thin air?
Also Samsung TW has notorious LAG and multi-tasking issues which this mod solves. The zram swaps keep the memory from maxing out as often so the TW lag is almost eliminated...
Finally, Multi-tasking is MASSIVELY boosted. You can keep more big apps running in memory without them being killed too early... test this yourself you will be able to multitask without hiccups to your hearts content.
===============================
This mod now comes in a stand-alone init.d boot-script version as well as the main app version.
The scripts come in 3 size choices as flashable CWM zips which also set up the reuired dedicated busybox

Turbo ZRAM app V1.2c:
>>> I Finally figured out how to set the swaps via init.d script!... Set on boot now runs via init.d
>>> App no longer needs a running service so takes up less RAM.
>>> Commands further tweaked to rely on the custom busybox. This should help people experiencing issues due to the wrong busybox setup.

THIS MOD REQUIRES A KERNEL WITH ZRAM SET UP AS A MODULE IN /system/lib/modules/. IT IS DESIGNED FOR KT KERNELS TW VERSIONS WHICH HAVE THIS SETUP

Original Development is stuff (ROMs/KERNELS) compiled from SOURCE code. "Ideas" are not Original Development. You would prolly be better off having it go in Android Development or even Theme's And Apps Or general. But this is surely not Original Development. BTW ZRAM has been around for a very long time, so i don't see how your the first to come up with the idea..

Yeah but I've never seen anyone set up four zram disks with an equal priority so they run in parallel and boost performance massively. .. But your point is taken. Apps n MODs is probably a better category

why 2 gb of ram is in use wile no app is running ?

My tab s 8.4 eat a lot or ram always 2gb in use wile their is no app is running? Why is that?

a lot of apps running on background

1 GB is also reserved for vnswap

vnswap what that mean?

It's just caching.This is a part of efficient memory management and not a problem. People who think it is don't understand usually. For common tasks, storing info in RAM is more efficient. System doesn't need to get it from SD which takes longer and uses more power.
That's a pretty simplistic way to put it but you should let your OS manage memory and use that 3GB to its fullest.

Well, Android is and was always using "empty" RAM as a file cache. How is this different and less efficient than Samsung's approach?

Reducing the amount of VNSWAP via Synapse in your kernel to 1 doesn't seem to do anything to the amount of RAM in use. So, do I something wrong or do I still don't get it?
EDIT: Sorry if my posting reads a bit harsh, it is certainly not meant that way Language barrier and stuff...

It's not supposed to.

synapse: Memory: VNSWAP control (1>1024 MB - Unable to disable (reset) / set size to 0 yet)
Click to expand...

It does change the size of the VNSWAP but doesn't reclaim the reserved RAM yet. Need to find a way as I quoted. I don't want to disable it fully in compile, i want to have tweakable options
Anyway, is OT from OP question and instead kernel development related.

I think it's probably some rogue app.. Go to Settings --> Application Manager and "Running Application" to see what's running int he background. But if it does not slow down your tablet, it should be fine. Just like my Mac, it uses tons of memory but OSX have such great memory management that my Mac still runs well.

Huh? That doesn't make sense at all. Android doesn't do that, it's probably more of rogue app. See https://developer.android.com/tools/debugging/debugging-memory.html

What he said. Every android device I get has a thread with people complain about ram usage. Android is based on Linux. Unlike Windows, Linux uses as much ram as possible all of the time to run smoother.
