I know that I have the phone just wondering what it looks like on other's
More running from ram improves performance so I wouldn't worry about it
Average 2.6gb free after a clean. I don't use heavy apps.
Unused ram is wasted ram.
I like the analogy of storage being like a very large library and RAM being like a table near the front. The books on that table are much faster to serve to customers than running to the shelves at the back of the library, so you keep the most commonly requested ones there.
The larger that table is, the more books you can keep on it.
It would be pointless and inefficient to keep that table clear and repeatedly run back and forth to the shelves for those popular books. Manually clearing RAM is the same as putting those books away. You WANT that table to be mostly full and Android is very good at sorting the books so only the popular ones are on the table.

That's actually a really good analogy. I'll probably pirate it in the future ?
That's a good analogy for performance, but what about power consumption ? How does ram loading impact battery ? Is the RAM chip sucking more power when full than when almost empty ?
In a word: No.
In a lot of words: RAM is one of the least power hungry pieces of hardware in your phone and it uses the same amount of power whether its cells contain 'used' data or not. To continue the book analogy, RAM is like a notebook where you make notes in pencil, erase them, make more, erase those, etc but the book always weighs the same (ignoring the infinitesimal weight of the graphite!). That weight is the battery usage.
In addition, CPU uses far more battery than RAM and the demands on the CPU are greater when applications are loaded from storage instead of RAM.

After using the phone 2 days without restarting I doubt that the free ram will be 2,6 Gb after cleaning the memory.

Hey guys i think this should be an important challenge to overcome maybe find out where all the ram is going and get it back without reseting our precious moguls. My experience its something that Task manager doesn't show up because when i end task on my DCD 3 1 2 ROM i dont get all of my memory back like right after reset. Also this causes inconvinient problem of starting GPS after few days of RAM going down to 8mb and not having enough to lunch TOMTOM.
Oxios doesn't not regain full mem only one third of it.
Can we some how make a better task manager or maybe purge RAM?
Writing a driver to consider our FLASH cards as constant RAM?
I would gladly sacrifice remove ability of my MicroSD for extra 4 gigs of ram and would let my memory leak on a period of roughly 4 years of constant usage.
Please lets get organized and stop hoping the next ROM upgrade will solve this issue.
This is one of the biggest downfalls of the mogul
I would suggest looking into how RAM works before making this thread.
First off, most of our ram appears to be lost due to memory leaks.
http://en.wikipedia.org/wiki/Memory_leak
And since, at least in my experience, most of the memory leak comes from Windows 6 (and so much worse in 6.1), you can't exactly end the windows task unless you...
restart the Mogul.
So no, an application, or task manager, wont do you any good. Not until they fix windows 6.1 up to not be lord of memory leaks. That is why new roms are often so desired, because only a rom release with some decent version of 6.1 with hopefully some patched memory leak holes could help our problem.
Second, you can't use a flash drive as ram, at least its not reasonable. You think the Mogul slows down now? Wow, just wait to you see it moving at the blistering pace of a microSD card.
Ram is so small, and so expensive, largely due to its speed. Thats why you can buy a 500GB HD for about the cost of 4GB of RAM on your computer.
Also, running from the MicroSD would be similar to the page file on your home computer. It runs from, in most cases, your C drive, its a fairly large file, getting even larger when you run multiple tasks on a low RAM system.
It is slow as a dog, and is one of the worst causes of system slowdowns. I also believe that MicroSD's have a limited number of read/writes. While not an issue so much for everyday use (taking pictures, running an app from time to time), if it were used as a swap file, it would probably wear out that SD card pretty quick.
So no, short of an amazing, simple amazing, piece of software engineering on Microsoft's part on a new Windows Mobile, someone developing some sweet, easy to install ram upgrade, or the new replacement for the Mogul coming out with more ram than we know what to do with.
You will be restarting your Mogul.
It should be possible to wright a Driver to USE RAM for swap file and some of main drivers but MicroSD card to be used to run all the extra features and programs. Also why our team of coders cant plug the memory leaks or find out the runing programs not seen by Task manager and have option to close them?
PS
Thanks for confirming my worst dream about the limits of our mogul. Also I notice that PPC on palm trios seems not to have these memory leaks.
This is maybe possible if we can build a tool that can reboot the shell without rebooting the actual OS. It can be combined with the command to free the memory when the OS is unloaded. This is my theory, i think that we can recover memory like this

while every single statement you say is true, your only wrong about how long ti takes to wear out a flash device. According to Toshiba, the inventor of Flash memory and one of the top suppliers of Flash memory chips, the 10,000 cycles of MLC [Multi-Level Cell] NAND is more than sufficient for a wide range of consumer applications, from storing documents to digital photos. For example, if a 256-MB MLC NAND Flash-based card can typically store 250 pictures from a 4-megapixel camera (a conservative estimate), its 10,000 write/erase cycles, combined with wear-leveling algorithms in the controller, will enable the user to store and/or view approximately 2.5 million pictures within the expected useful life of the card.
For USB flash drives, Toshiba calculated that a 10,000 write cycle endurance would enable customers to completely write and erase the entire contents once per day for 27 years, well beyond the life of the hardware.
take into note that is only 10,000 write cycles. 100,000 which is common for most flash drive now a days. so no, he wont even be around to see the day his flash drive even wears out. LOL.
Glad to see this post picking up some steam But lets Try and focus on making A solution rather than discussin known facts
the known facts have already pointed out the problem (memory leaks in the OS) and the only solution we have without the source code (restart the OS by rebooting the phone) so what else is there to discuss?
oh yeah, we can talk about ways to get the source code so we can fix it.
well i posted one idea:

I returned my A101 a few weeks ago because memory would get down to 50MB or so after a while, and the whole tablet would then become quite sluggish.
I liked everything else about it, though. I wonder if the new firmware manages memory more efficiently and allows free RAM to stay at 80MB+ or so, or perhaps keep apps from loading themselves for no reason.
I'm afraid it's a hardware issue (simply too little RAM to start)... but you never know. Surely the Archos people by now have had an earful of complaints about this issue...
Free RAM on my archos 101 is constantly at 30Mb and I have no problem with sluggish performance.
I never kill apps unless they misbehave badly (badly written apps).
You can not maintain a 80Mb free level unless you don't use the device.
Killing apps just to free memory is a big nono.
Android uses a method to kill background apps automatically when space is needed in RAM. So effectively it cleans up after itself.
Here is a fairly good explanation of how the system is designed.

When I first got my Archos 70 IT 250GB, I was constantly killing apps! Didn't seem to do any good, but I kept killing those apps ... I almost sent my Archos 70 back too. I even got the RMA from J&R. I don't think I'll be returning this beauty any time soon .... Also have a 3-year extended warranty.
Until I learned that it isn't necessary. I quit killing apps several days ago, and my Archos is running more smoothly. Still sluggish at times, but I have 12 folders on the desktop, along with 9 shortcuts! Most of those folders have lots of apps in them. I'm guessing that is why the desktop is so sluggish.
I can have Internet radio running while doing other stuff. The radio cuts out sometimes, but isn't much of an issue.
Internet runs smoothly about 1/2 the time. I didn't get my Archos 70 for high-end usage though, mostly just for reading, and watching short videos, and listening to Internet radio and playing music when I'm out and about (riding the bus, riding my bicycle, shopping).
Really comes in handy for having my shopping list with me, listening to my favorite tunes while walking around! I also have sticky notes with daily journal reminders that I'll transfer to my MacPro. Also use the calendar for appointments and events.
Some interesting reading in those 2 links. Thanks.
In the SGS task manager the RAM (after everything has been cleared states 291MB/833MB why is this please?

Answer is simple, total ram is 1024 Mb but the gpu required 129 mb. So the rest remains for programs. 291 is used by android system.
thats 542 mb free. my galaxy s when cleared shows 154/304 so only 150 free. Well over 3 times the amount is very impressive.
I hope that dosent mean theres just 290 free ram, but it might be the case. my DHD has 768mb ram and im usually around 200mb free all the time, sometimes even like 115mb when i use a few apps. android has some serious ram eating issues.

On my GII...
Samsung's Task Manager: 233MB/833MB
TasKiller: 596 M Available memory
The operating system is supposed to fill up the RAM as much as possible, Android is trying to utilize the resources at their best. "Free" RAM doesn't mean a thing, it is better used as a cache. Parts of that cache will be dropped as soon as an application needs more RAM. Windows uses RAM in a similar fashion.
You shouldn't run any "RAM freeing"-programs as they are counterproductive - typical snake-oil software.

I'm all for putting my RAM to good use, the reason why I use a TaskKiller is to exit apps which after a day of use continue to run even though I'm not using them / apps I forgot to exit.

Of course, but it just amazes me how much ram is needed by android. I say this because, on every android phone ive had to date, once the ram goes below 150mb, things start to really get choppy, i dont know why. I assumed by that point, every app i would use is already in the ram so it should actually make things faster, but normal things like opening apps and scrolling through menus start getting very choppy, even in apps things are choppy which lets mek now ram is low. Thats when i realize i need to do a quick reboot.
In that sense, i really have a lot of respect for apple, they do some crazy ram optimizations. I know they dont have things like widgets or whatever, but everything runs like butter, also you have to admit the iphone4 has a very high res screen and the apps are much more visually taxing but they are damn fast. But with 1gb of ram, I doubt we will be running into these issues.. I wonder if the SGS3 will have 2gb ram..hehe

The ram issues on Android are because of how it's designed.
iOS each app has it's slice of RAM that is managed completely by the app itself. When the app exits, the OS doesn't check anything, it just flushes the whole piece of RAM, which is very quick. When 'multitasking' and the phone runs low on RAM, it can quickly flush the ram on any 'background' app without having to do any checks.. very fast operation.
Android has a far more complicated structure, with the Android system managing the RAM within each app. Each app is broken into separate blocks (activity, service, etc) and while the whole app can be flushed (with a force close), Android doesn't do this. When Android is low on RAM, it follows a set order on what to close first, such as unused activities. This takes quite a lot of calculating and slows stuff down.
All those complications are 'fixed' with the SGS2 though. Dual core means the calculations don't bother your running task. High ram means the calculations don't happen often. Works very nicely.
i use tittainium backup and freeze unwanted apps, i get around 650-700mb free
The SGS2 has 1024MB of RAM. 833MB is available to the Android system and the rest is used by the radio.
I would like to ask some users...
Somebody reported that they have 910MB of TOTAL Ram.. Some have 830+
How can i know this?

Hello,
I am about to get the G9 80 Turbo as the form factor appeals to me. However I am reluctant due to the 512mb RAM. The only experience I have with HC and memory usage is with the HC roms for gtablet and the memory his been a tad high edging towards 512mb .... I do have a number of background tasks running but nothing crazy.
Anyhow does anyone know if the 1.2ghz turbo still comes with only 512mb - archos isn't too forth coming with this info on the tech spec sheet
Also what are folks experiences wrt to memory usage on the 512mb G9 80... (I'm getting mixed reviews)
Thanks a lot, FredT
As far as I know, the turbo devices are still 512mb. I do experience some lag on my regular 80 at times, but a reboot generally fixes that. I am stock everything, so I haven't tried different launchers to see if that helps with lag. I love this tablet, just wish it had a bit more RAM.
Yea archos are tight arses when it comes to ram Scrooges

So I took the plunge and picked up the G9 80 Turbo (1.2ghz). In a nutshell it does not rock.
Archos, why oh why did you not go with 1gb RAM ?
I get it, the price point of this device was key, but I still feel that compromising on the RAM was a mistake and will cause a suboptimal user experience.
Frankly I worry how ICS is going to run on this.... hopefully ICS has optimized memory usage.
At this price I certainly have lowered expectations but the 512MB RAM and the screen ripple (which mine does have) is making me rethink this purchase.
The problem is that I really like the device's form factor and overall make-up, so I want this thing to be successful...
I use my tablet 3 hours a day but only have the basic android apps installed/running: facebook, RSS reader, tweekdeck, tvshow sched watcher and the standard android / google framework stuff... I even turned off the live wallpaper.
...and it still feels draggy overall and painful when switching from say tweetdeck to browser and then back, tweekdeck and/or the browser have to reload data and reset positions. Frustrating...
I now understand why Archos bundled the convenient System Monitor with the Kill All Apps button
Each time I check free memory it shows 50 - 60mb free, I'm going to poke around and see if I can figure out where the memory is going - maybe I can optimize this thing a bit.
Anyhow with all that said for the price I think I am going just keep it to hack around with android and as a GPS tether to phone...
...but I can not see using this as a daily driver.
Which is a big shame as I think Archos is on to something with this device.

Couple of things you can do to get it to run faster are : install ADW launcher EX and Advanced Task Killer, those 2 should get you running a bit better, other thing is, root the device and get the CPU to run 1.2GHz Full blast...
I didn't realize this thing has 512mb. That stinks. I thought the Turbo ones had 1gb like my Acer A100. That's not very Turbo to me. I just re-read a review, said it has 1gb. IT assuredly does not.
I've been using this tablet for about 3 weeks now and it is amazing, you just need to do a few tweaks and it is well worth your money, might not be as "perfect" as other tablets but it is spectacular for under 300€
I do like a lot about it, for the day I had it. Seems as fast as my A100, but I had to send it back due to 2 stuck on pixels. Hope the new one doesn't have bad pixels. I want more storage and battery life than the Acer, the Archos should hopefully do that.
I've been quietly lurking on this site for about 2 weeks since I got a nook tablet (16GB) with an N2A card (which was horrible). I came to this site looking for a way to mod my device and ended up learning a lot more than I intended. I have sampled quite a few ROMs on here and am astonished at the amount of work that has gone into these ports. I have a device that is so much more functional it's not even funny. Already I've reclaimed the space that BN had partitioned from users. I still have a lot to learn but I wanted to express my thanks to all the developers who work hard on these. I am very appreciative that a device which is technically 'obsolete' can be revitalized and turned into something very usable. I am still trying out various ROMs to try to see which is giving me the best stability and RAM use. So far the one I am using I unfortunately forgot the name of. Any way of finding out which ROM you might have flashed? What I like about it is most of the ROMs use so much RAM I am left with around 200MB of RAM without anything running. One particular ROM I'm using consistently gives me around 400-450 MB of free RAM even with some background apps running. A HUGE improvement. A couple ROMS literally left me with less than 100MB. Anyway if anyone has any advice or happens to know how to determine which ROM I might be using I'd be very happy. Mainly I wanted to introduce myself and thank the developers. GREAT STUFF!
Some info that most Android users are not aware of, as its a bit non-intuitive:
Having less memory (RAM) available is actually a good thing. Apps can be "running" in the background without actually using the processor or other resources. They are cached via the RAM in order to allow you to relaunch them quickly. Android's memory management is quite good, albeit different from say Windows.
This is why Task Killers are generally a bad idea. I used to use them as a means to kill apps when they froze or whatever, but now, with the roms I have on my devices, I have set long-press of the back button to kill the current app, should I need to do this.
Read this article for a bit more info.
tl;dr less memory available is not necessarily a bad thing on Android.
Sorry for delayed reply
Forgive my tardy response. Our internet was out for 2 days. I understand what you are saying but what I was noticing was a huge number of active programs that were not in use, nor are commonly in use enough to justify their being cached. One particular ROM was leaving me with less than 200 MB of RAM with the same processes referred to above being inactive as well. A 200MB difference with the same stuff running. The particular one I'm on now keeps a number of things running in the background and still leaves me with well over 300MB with 4-5 programs going at the same time. So while I agree with you that some might be doing more cache than others, my experience is telling me the build with the most RAM (ie whichever one I am using...I unfortunately forgot which I installed...a CM10 but not sure if it was the cherry pick or chris'.) is the one that is managing the memory the best. I can figure out no other explanation for the same number of programs using an extra 200 MB of memory over another rom and thinking that is a good thing. For example, the ones I am thinking of are running stuff in the background I don't even use. Power Amp is a huge offender for whatever reason. I see no reason to have it running 24/7 but it does!
