Quick Memory Question

I am looking for a new XDA phone and I noticed that most have 64 Ram, but 128 Rom. On my xda I the rom had to be flashed and the ram was used for storage and running programs. Is this not the case anymore? Thanks.
-Ross

ROM in WM2005 is used for programs and storage, while the RAM is plainly program memory for the programs to run into.

Well then in that case, do you not lose your data when your battery dies. Or is there a seperate rom for OS?

That's right...no more data loss.. ...this is called persistent memory in wm2005...(a hard reset or even a normal flash won't delete ur data,u will have to choose an additional option in bootscreen to delete them..)

Memory problem(WM6): Storage -vs- Program

I know this was a problem in WM5, but is there any way in WM6 to force it to use more memory for Programme's instead of Storage.
I have 20 MB for storage, but only <10 MB for memory.
The problem is that is get a lof of "out of memory" errors when I'm using iGO (SE) and therefore want more 'real' memory to work with (I do not use 20 for storage)
Anyone got a "tweak / software / trick" to do this?

Storage is flash, program is RAM. The two are totally different on WM5 and newer devices compares to WM2003se and older devices.
The Himalaya is not an example of tweaking the allocation as this was not a WM5 device.

Yes, I know that in wm2003 you could easely change the amount between these two. I noticed that everytime WM5/WM6 is started there was a different mount of flash/ram, so WM is changing this every time ?!?! (so you could manuputalte this?)

What do you mean with that (I have a universal / T-mobile MDA pro)?!

The only WM5 device you can change the amount of RAM vs Storage is the Himalaya, this is because it was a WM2003 device and it used RAM for both storage, and RAM to run apps in.
WM5 devices don't use RAM to store things in, just the partitioned area of ROM.
You can not use ROM to run things, you only have the RAM, so if you are running out of space, your only option is to run less.

Unless, the universal had NOR based ROM, which could XIP

Man! You would have read my mind! I was discussing the very same subject this morning with a friend of mine, but unfortunately he was unable to explain (he's a nokia freak), so I could save a new thread by sharing my views over here.
My query was if Uni has got 128ROM and 64RAM, Eten M700 has got 128ROM and 64RAM. Now, how does the respective reading be Program Total: 48.07 MB & Storage Total: 43.72 MB (cooked rom below)? Whereas M700 has got 128ROM and 64RAM, reading is Program 47.52 MB & Storage 70.24 MB!
If I drop a ringtone or copy an image or even an application, would it utilises storage or program? If I install a cab file, would it go to program or storage? I am facing a terrible issue when I use couple of applications even after closing them, I lose about 10 MB! I know some cooked ROMs had a program memory of 52 MB!
Any one could explain?
BTW, what's XIP?

Storage. WM5+ uses 'storage' to store apps

Again, storage(this includes other storage media like extended rom and storage card)

XIP=eXecute In Place. This is a common property of NOR based flash media. NAND based flash media cannot XIP. XIP lets the apps to execute in the ROM itself.
XIP is mostly used by Palm in their Treos to store the OS

Big thank you for the explain. Now, what about the difference in total memory reading among different PDAs?

How to tune filesystem cache for increased performance?

I am using WM6. My free RAM is usually around 7-10MB.
By using Advanced Configuration Tool, how do I tune filesystem cache for increased performance? How much cache and other values should I put?
I don't know much about this, therefore asking the experienced members...
Thanks

Is it something that higher tha value, better will be the performance?

if u want better performance try using homescreen plus plus and overclocking it
or maybe changing the pagepool of your rom
or flashing a different rom lol

Can u tell me how to change the pagepool of the rom?

I wouldn't bother with filesystem cache as this setting isn't used in WM6.
PagePool I would keep to 4-8 depending on your device (if 128M or over, don't set). You can only set PagePool before you flash your ROM. It's easier to find the ROM that is made for your device and RAM.
Best to see what they say in your own device forum.
Overall depends what app's you use, and how many at once. These questions tend to be device specific and which apps you use. (What app are you trying to increase performance for? Or what ROM? Some require speedup of SD, some RAM, some GfX, and all these are device specific, and may not be able to be sped up, and some decrease in other areas - for example increasing PagePool will decrease you available memory. Most ROM cooks know how to fine tune these things.)

Ram usaged with WM 6.5

Hi,
After i upgraded to WM 6.5 Stock, my ram consumption has gone up from 45% with WM 6.1 to around 65-70%.
What are your thoughts about using a tool to free ram - does it help?
And what is the best tool to free ram?

I don't think it'll help. The official rom is badly bloated.
My build uses all of the official Packages on top of the latest WM6.5.1 build 23506 and memory usage is about 34%. That's running the official Manila 2.1
So I have no idea what they're doing.

VM 6.5 and memory usage
Well another approach to the memory usage is, how to get it down?
Is there anyt tips & tricks to get it down?
How much memory do you need in spar befor is a problem and have influence on the performance of the phone?

Its true that 6.5 uses more ram, and even more is used if you have moved over to manila 2.5. But as long as you have ram free it should not affect the performance of your device.
clean ram programs do reduce ram usage that has increased over a few days but you will not get it below the amount that is used just after a soft reset.
Sometimes having things "cached" in the ram will improve device response if those items are needed frequently, so not all ram usuage is actually bad.

Hey guys,
found it on another board (pocketpc.ch)
HKLM\SOFTWARE\HTC\ResProxy\ShareMemSize set Value to 100001
i dit it and its amazing, after a softreset it starts with 42% of memoryusage and til now no problems with any apps, so i think its a good tweek
thanks to the poster on pocketpc.ch

That was f...... amazing!!!
Memory use is down to 48% and the small delay there sometimes was in the interface is totaly gone. Startup of apps is also faster then before and everything seems faster.
So for now this registry change has done wonders for me. Only time will tell if there is a down side to it ;-)
Thanks rol13.

Hi,
it's not obvious(no A to F letters to guess) but you might have said, it's an hexadecimal value
regards

I noticed the same problem after updating tot 6.5.
I'm not very experienced with tweaking my phone. How can I use the mentioned tweek? What do I have to do and are ther risks involved?

there is always a risk when tweaking your phone, however, since many of us here seem to be having to negative results from this tweak, then you can say it's safe. search xda for regedit, download and install on your device, then use that program to tweak.

What Registry Base?
I dont understand, when I set the value to 100001, the radio button base has to be selected 'Hex' or 'Dec'?
Thanks for your help!

Thank you, done, works just fine.

Thanks works great, usage at 42% now

if your using htc sense try getting the 'no push internet' cab file, as that will stop the push internet service on your phones and save you around 10%
for thoses that are unsure, push internet is where htc sense, will auto load web pages for you every hour or so, this makes the first page load instantly, and thats about it, so not much to lose out on

I would like to add a small note about this tweak before we all start thinking this is giving us something for nothing.
this reg tweak will prevent TD2 from pre-caching files for the following HTC applications:
AudioBooster, Calculator, ContactCard, CUIHandler, FMRadio, HTCAlbum, QuickGPS, Recorder, StreamingPlayer and YouTube.
They will now be dynamically cached, and then dumped from ram as they are used.
If you frequently using these apps it will be slower to launch when you 1st use them as they will need to be moved to memory before being executed (you can prove this yourself buy timing them before and after using the reg edit)
If you look at many diamond/TD2/HD tweaks the performance ones that make most difference are for file system cache, font cache, glyphy cache ect...
This works by allowing greater amounts of memory to be used by these caches, and more cached data gives better performance at the cost of less available memory.
so long as you always have enough free memory for the apps you want to run these performance tweaks are good. but if you go too far and run out of memory your app will crash or phone will just start to crawl
So using your memory is not a problem, and for many people it is better to have common apps and system files cached in memory ready to use instead of being able to see 50% free memory doing nothing (remember you have paid for this memory, make it work for you)
But if shortage of free memory is a problem for you then certainly this tweak will free up ram for your applications that need it.
as a side note another good way of freeing up alot of ram is to dissable push internet using a cab found on these forums. this obviosly comes at the cost of losing push internet, but if you dont use it whats the loss

thanks for the great info rumpleforeskin. one thing i would like to mention, after applying the tweak, my internet speed (using 3g) dropped significantly, and it was almost impossible to get a gps signal, as soon as i restored my registry back to the way it was before the tweak, everything went back to normal, i got my 3g speed back, and gps was almost instant. something to think about before using this tweak! or maybe it was just me

Brilliant! Down to 52% after a soft reset, thanks.

In my case Topaz from Spain, Official Rom upgrade from HTC, after change the value & soft reset 41% Ram occuped (before the change 48%), without problems with programs,
great tweak.

this tweak sets the share memory to 1 mb while the default is 15 mb.
yes you will have some more ram free but this will make Topaz work much more because now it has to read write to the ram all the time.
so whats good with this tweak
You get extra 5-10 mb ram free (thats what you think) but those extra ram are not free really because they will be used all the time to read what should already be in the ram.
this also causes the cpu to work more causing more drain on the battery.
so you will loose more then you gain

what you write is true, i made a post a little futher back describing the pupose of this cache file, and all cache files.
The original poster of this tweak done a good job of finding a way to reduce ram usage which will be very helpfull to the few people who need to use that extra ram.
but i worry that many people will use this tweak just to lower their ram usage not understanding that memory cache is there to boost performance.

[Q] Identify where programs installed to (i.e Main Storage or Storage Card)

Hi all,
sorry if this has been posted already. looked around on google etc but to no avail.
i seem to be always running low on Storage space for installed programs on the internal memory. plenty left on storage card which is fine for installing games and other apps.
however for screen mods and themes etc i.e BSB tweaks, CHT etc. I always install on the phone memory, which is now running very low.
ive tried removing all cabs no longer in use or used rarley and still have little memory, plenty of spare memory under program but not in storage (on main memory)
so im looking for an alternative to the standard 'remove programs' function which will identify what cabs are installed to the internal memory and what is installed to memory card.
or alternativly a way or transfering some of the internal program storage over to the main storage.
this will save me having to do a hard re set to restore all storage space and re install cabs again etc.
im running standard WWE 1.48.405.2 Vodafone ROM, Radio 2.05.51.05_2 on WM6.5, HD2, any help is much appreciated, thanks, Batez

use pocket mechanic to transfer applications (which phone mechanic is able to transfer) from main memory to the storage card. This app is not free though but works a treat. Not sure if there are any free apps out there which can do something similar.

Thanks Mate

Thanks Adamjee, this looks like the app for me should do the trick, and with the other functions available i think its worth the cash, although i may keep searching for a free alternaitve first ill let you know if i find anything. now i know the sort of software im looking for will defo help me in my search. much appreciated Adam.
