[Q] Desire HD Ram only 623MB..?

It is true that Desire HD ram only 623MB..? I've check with Android system info..

you are right!
my info (of quadrant) says i have 638 mb ram in total.

that is the total ram aMount of0 free RAM!!!

i dont think so, the programms says TOTAL amount of ram!
my free amount of ram is about 300-400 MB when with usual config.

Correct. The total amount is 768, but some is used for OS stuff.

Yeah first 130mb or so is reserved for system use. Stops apps from grabbing all the memory and making your phone lag.

Not OS stuff, more for low-level hardware. Linux only sees ~624MB RAM. Some claim the rest is taken by Fastboot, but disabling it does not free it up.
I suspect it is probably used for GPU memory, unless there is some limitation on the max memory the OS can handle.
Another option is that it might be some kind of volatile filesystem.

Hmmm.
My desire hd says , gig in ram, used 411 MB and have 752 MB free.

Bad pictures I know, but there you can see.
Not rootet, new OTA update as rom.
And I have allot of installed apps.
411 mb it says.

That is not RAM, it is the internal storage (NAND). It has about 1.5GB of usable space.

Ok, thanks, thought it was this it was about.
Sorry for messing up.

According to HTC it says 768 MB. but maybe some are reserved for system APP

DHD has 768MB all RAM memory, 640MB for apps, 128MB is isolated for the ARM7 processor that operation radio (radio = your all wireless connection)
DHD has 2GB nanad flash.
550MB for OS. (after update to 1.72 reduced to ~450MB)
1GB for data.
300MB for cache.

Sorry, OT.
@syklitengutt: How did you get so many icons on your power control widget? Are you on 2.2 or 2.2.1? I am getting only the default 5 icons and I am unable to change that.

128mb is reserved for the chipset, but the majority of it is used by adreno as vram....

Try advanced power bar, its fully customizable

reply to this. ok
i have 653,561... so 653mb ram in my DHD. that is total memory showed by memory booster lite its freeware and its GOOD app.
so 653? why not showing 768? are there reserved memory for OS ? best i get to free ram was 510 mb free and 150 mb used... answers please
use GDE it uses less ram than sense. i pick GDE when rebooted and it saves about 10 to 20% of ram!!!!! GDE good.

[Q] ram and over clocking

is there a way to increase ram?? how to over clock wildfire s??

You can overclock Wildfire S up to 806 Mhz with Alquez's CyanogenMod 7

cm7 port is not fullly developed i wud lik 2 w8 for it 2 fully develop...i just installed JikantaruROM XE yest...can i over clock in JikantaruROM XE??? what about ram?

Can't increase RAM, and CM7 is 99% fully developed only thing left is camera flash.

512MB RAM is good, no reason to expand it by swap or something else.

tat 1% is oly important 2 me...hope it is fixed soon....512 ram in tat 250 is always occupied

are you talking about RAM or system flash memory? both start at 512mb but both go down quite a lot. RAM ends up about 300 before boot and about 200 after everything's running. System memory goes down to about 70 with stock ROM and about 120 with a cleaned out ROM, but drops by about 40mb just from syncing contacts and gmail, etc.
data2sd or another similar app let's you have up to 2gb of system flash memory. Remember these are completely different from RAM. you can't really increase the ram.

The only way to 'expand' your ram would be a swap partition on your sd, but this isn't the best way, because it's damn slow and should only be used as fallback within alert situations. I also don't know if sense roms support it.
Swyped from my HTC Desire S

What obvious reasons to use swap in this device? Which app consumes whole system memory? Any ROM with plenty widgets fired on gives 200MB free ...

im talking about the RAM...200 is always occupied...250 is free after killing all the unwanted apps

[Q] memory (RAM) size

Hi,
obvious question (but didn't find an answer): Accroding to http://www.htc.com/www/smartphones/htc-desire-z/#specs it should have 512MB RAM right? Why the actual amount of memory is significantly lower? Free in terminal shows only 386048000 bytes which less than 370MiB. Why? Free should show actuall memory on which the underlining linux is running, right? So there shouldn't be any other hidden memory.
Thanks.

Free memory is how much memory isn't being used by the system, files, apps, etc., that being what is available to write to; total memory is the combination of used and free memory.

I had the same question too
The answer is that part of the memory is used by the sistem itself.

Yeah, part of the memory is reserved for the radio, and probably some other system stuff too. So when Android boots up it only sees around 370MB or so. This is the same on both the G2 and DZ.
Sent from my Desire Z running CM7.

Other stuff.. and something like "Graphics Card" i think.

Hm, hm ..... so 512MB is just marketing. 1GB phone has effectively almost 3x more memory Desire Z is awesome phone (it has HW keyboard), but the memory is a huge disappointment, what would cost extra 512MB these days? Almost nothing ..... grrrrr

A 1GB device would show about 874988KB in RAM. Or about 854MB.

How much free ram do you have?

Ehi guys how much free ram do you have?
Mine shows like 40mb only everytime, how to increase it?
Any mod?
Or other things?

Already using it

Free RAM is not the issue, it's whether your phone has breathing space.
For instance, I can have 50mb free but everything runs fast because the RAM is used up by apps that I use.
However, if your RAM is being used up by background services and apps that you don't use, then it will produce occasional slow down.
In other words, free RAM is not the goal, but properly utilised RAM.
All this being said, I hope RAM management improves with ICS.
When you restart your phone, check the RAM after it fully starts up (without opening any apps). Mine is 150 used, 150 free.

I have 267MB free.. Arc S...

You on a custom ROM?
I'm running stock, rotted, so some system apps removed.

Mine has around 140MB of free ram.Try to reduce unnecessary widgets from the homescreen.

If rooted use titanium backup and move internal apps to system.
Use the integrate into ROM function. System apps have there own partition.
This might help with lag issue.

Can you explain me better please?

If you want a lot of free ram
Just install Gemini task killer and app manager ..also download fast reboot from the store
I usually get about 200 meg free ram when i reboot and about 175 free ram after 24 hours ..
I am rooted and using aniking rom ...

OK if your phone is rooted then use an app from the market which is called titanium backup.
Once installed press menu button select batch option look for option to make a backup of all 'system apps and user apps'
once the backup its complete. Look for option in batch setting 'integrate into ROM'
This will move some internal apps into the system partition of the phone, this will free up your visible internal free memory.
I have moved maps, gmail, adobe flash into rom and they run with out any issue and still update
Hope fully this will help if you are having any lag issue.

I have 100 to 150 mb free. I use icelite beta1, but i have installed ram manager free from market becouse my ram was always under 60 mb and i have experienced some lags. But now all works fine. Hope it helps

When it starts it has around 200MB of RAM, with moderate use (Browser, YouTube, maybe a game, Twitter..) around 140MB, never goes below 100.
I have Arc S, currently unrooted (bricked it once, waiting on ICS)
and I think RAM managment will be better in Ice Cream

185 ~ 165 MB

Just curious where y'all are picking these numbers from? And just how many are confusing "RAM" with "storage"?
And, don't forget, "free" (as in unused) RAM is wasted RAM. In a perfect system, you would have 0 MB of free RAM, as every bit of RAM that wasn't currently in use by an app would be used to cache data to prevent the uber-slow reads from disk.

Phoenix is right. Free RAM is wasted RAM
Sent from my LT18i using XDA

0 ram in a perfect system? There must always be some free ram, because new opened apps need it. But je can use swap memory. I use it to, and it's boost my system. But use a good sd card when u want to use swap memory. I have a class 10 sd card, so I don't have any problems whit my swap memory. I installed a2sd and use the app a2sdGui tot set the swapines. Swapines is how much the system use the swap memory.
Swap memory is the same as virtual memory in windows. But when you only have a class 4 sd card, I don't advice you to use swap memory. And whit a2sd you also can put system apps to your sd, on a sd-ext partition. Search on XDA and you find something about it.

No, you don't need free RAM for this. RAM currently being used for Cache, marked as Inactive, or used for Buffers will either be discarded or flushed to disk, and then that newly freed RAM will be used for the new app.
In Linux (which is what's under/behind Android), there are 5 categories of memory usage:
- Active (RAM currently in use by the app)
- Inactive (RAM used by apps that aren't currently running but were recently so could be used again quickly if you run the same app again)
- Cached (RAM used by the OS to cache disk reads/writes; can be flushed to disk at any time for use by apps)
- Buffer (RAM used by the OS to buffer various things; can be discarded at any time for use by apps)
- Free (completely unused RAM just sitting there doing nothing)
In a perfect system, Free would be 0. Any available RAM would be used by apps (Active) or the OS (Cached/Buffer). And anytime an app needs RAM, it would grab it from the Cached/Buffer groups.
But je can use swap memory. I use it to, and it's boost my system. But use a good sd card when u want to use swap memory. I have a class 10 sd card, so I don't have any problems whit my swap memory.

Swap use is an indication that the system has too little (not enough) RAM for the number of apps you want to use and is really just a crutch. The less swap you use, the better the system will run.

And, again, how are you measuring "free" RAM? I'm willing to bet that what most people are measuring is not actually "Free" RAM, but what the Settings --> Applications --> Running applet shows as "free", which is really a total of Cached, Buffer, and Free (IOW, it's showing "RAM available for use by apps" and not "Free, as in wasted, RAM". Those are two very different things.)
Install a real stats/monitoring tool like Diagnosis and configure it to show "free" ("Real free memory", not "Total free memory"; the former is Free, the latter is Free+Cached+Buffers) memory, and you'll notice that it will hover around/under 5 MB most of the time. When you first power on, "Free" will be 40-80 MB. Fire up a few apps, and it will drop down to almost 0 MB. And it will hover there until you reboot the phone.
Which is exactly what it's supposed to do!
"Free" RAM is wasted RAM.

[Q] Available RAM issue

Hi all. After flashing TrueAncestor 1.6 LE, I had about 330-340 total available ram (free + used by running apps). This was a long time ago, but still is like this if I reflash it.
The issue is on my running apps tab it shows only about 240 mb total available RAM! When I restore the backup, that is. I don't really know how or when it happened. Maybe it's due to installed apps, but I can't really find out how is that possible.
Edit: I found out via advanced restore that the problem lies in the data backup, but I can't figure it out.

ram or internal memory btw?

Try run sme RAM killer app, like GTA Vicecity ... then exit game a check free RAM ...
BTW - on my Xperia S (1GB RAM) i have frree only 250MB and no problem at all..

ram. it's not that i have a problem, it's that 100 mb of ram somehow disappeared. i flashed another rom and i'm doing an app-by-app restore with titanium backup to avoid restoring whatever caused me that issue...

It is because of the app, also maybe the kernel n the rom u used, i used turbo kernerl jb+ jellyzeus rom, superb fast, no lag at all, smooth when play games, although i got 100mb out of 377mb,
Sent from my R800i using xda app-developers app

Check the CosmicDan's sig "free ram is wasted ram" when apps will need ram they will just free it by themselves. I'm having max 180-140 ram in daily use which isn't much and everything works fine. Either way 330 mb of free ram - WTF? Yeah it's caused by apps. Many apps are running in the background or just idling. It may be that rom itself does something which will eat some ram to make itself smooth and then free it up when needed.
Short version - it's okay, don't worry.
Sent from my R800i using xda premium

mmh... seems like i've not explained the problem well enough. I know free ram is wasted ram. I'm talking about the total ram. By total available ram I mean free ram + ram used by processes you can see in the "running apps" tab. The 330+ mb of *total* ram is what one should have with this phone. I had only 236 mb. I did a reflashing restoring app by app, and now I have like 300-310 mb of total ram. That's still kinda disappointing since I don't know how is that. Out of the 512 mb installed, system processes which are unseen by the "running apps" tab in settings take some, and that's okay, but to have 236 mb total means there was some other invisible process that was either disguising itself as a system process or letting the phone believe it only had that much total ram.

You should used custom rom n kernel, some stock rom isnt that great,
Sent from my R800i using xda app-developers app

there are many users with stock rom and kernel which get 360+ mb of total ram, your answer is not helping that much. Also because i'm not using stock rom lol.

No, i mean sometimes u need to flash stockrom to get corect baseband n then install the rom, it just to avoid any prob after,
Sent from my R800i using xda app-developers app

well, i found out that it doesn't depend on the rom anyway. When I link the phone to the pc and the sd unmounts, it all gets right, the total ram is what it should be, but just for the first moments, then the total ram is cut down by a lot but i think it's normal. When i take the phone out it regains all the ram, but when the sd mounts again, something like 40 mb of ram disappear just like that.

sorry for double posting, but I realized other things:
actually, the ram programs like setcpu and quadrant is the correct 367 mb.
Unmounting the sd card eliminates the problem as long as the sd remains unmounted; mounting immediately brings it back. Messing with dalvik vm heapsize does nothing, engine flushing with supercharger does almost nothing. I absolutely don't know what to do. Even my older screenshots from when I didn't flash anything has like 330-335 mb total ram, instead of the 345-355 it should be. Now it's about 305-310. More than 55 mb are not reported by running apps and this affects gaming, as ram heavy games like 9th dawn, everland crash and aralon + gamekeyboard can't stay in background together if the graphics options in aralon are maxed out.

If it still persist u should try uses swapper. Great way increasing ram,

I am too facing this issue, after booting I have like 340 mb of total RAM(100MB in use and 240mb free) but after using phone for quite a while the total ram decreases a lot(110mb free and 100mb) in use, where is rest of the ram?? how to recover it?

U just cannot recover the ram. U should better try the new rom. Try atomic gb rom. It fastest and stable. And u should not get to furious about ram. Just see the phone lagging or not.
