[Q] upgrade/add/overclock ram

Hello guys all of you know that we have 512MB ram I want to know if i can add some to ram form sd card or by overclock it such as the computer's ram so how?? or it's possible (I am not believe any thing is impossible )
is this work? https://play.google.com/store/apps/...t#?t=W251bGwsMSwxLDEsImx2Lm4zby5zd2FwcGVyMiJd

It might be possible to use sd card memory as ram but it wouldnt be as fast as a real ram
Ram chips are aweful fast
I think though that for this processor it wouldn't be an inconvenience
Try it

Swapper

okay in face I used it before you tell me so can I stop it??!! and delete swap space (especially it will not get my phone faster)

You can remove the swap file from your sd card using a file browser like astro or something :thumbup:

I'm using swap in my old gt540 for about 1,5 year and card works fine. I don't feel like I need swap in OB for now

My problem is in games if ihave 180 free ram or less the games lags so i want to get more ram so No ideas????

How to have more free ram ??

Which kernel should i choose ??
i use DjangoManouche 1.5 now
i have a total of 330mb ram only
any good idea i can do

I believe you have 330 mb because the rest up to 512 mb is reserved for system apps. So you can use root explorer and go to /system/app and remove some system apps you don't use and reboot the phone. Just be careful not to touch stuff that is required for the phone to boot. And no, I don't know exactly which these apps are. But here is a tip: I always remove gallery, news and weather, all google apps, music player, stock email, navigation software if there is any, live wallpappers, file explorer (not before getting another though) and everything that's about visualization in general. These things are safe to remove.
And btw the amount of free ram is pretty much irrelevant to the phone's work because the kernel tries to utilize as much ram as possible and then it gives it away to ram requiring apps for the moment. I am just trying to say that you need not worry about free ram if the phone is working correctly. And if it's not it is most likely not because of used ram but some app is not behaving as it should and is using the CPU too much.

You should consider using a kernel that has OTF settings or a RAMhack. I recommend Etana but for some reason I love Temasek's Kernel. They both have the RAMhack option. It basically takes some of the RAM that is reserved for your GPU and makes it available for your device so you'll have more RAM for running applications etc. You shouldn't set the RAMhack too high though, 32mb/48mb should be fine. Additionally you could freeze some system apps that you don't need and use an autostart-manager in association with a task killer to kill applications and not allow them to restart themselves.

What did I just read?
Don't do what was posted, you'll most likely break everything.
System apps uses system storage not ram. Deleting those apps will not give you more ram. But more system storage maybe.
Ram is used to save the current state of opened applications. Though the reason you only have 330mb left, is cause the gpu uses it as shared memory.
A ram hack is an option, as it reduces the amount of ram that goes to the gpu. But the use of a ram hack over 48mbs will break lots of things, such as recorder, camera and instability in games.
In all honesty, there is no use for a ram hack 330mb of ram is enough.

If you use DjangoManouche you have ram profiles, another option are to use swap, the benefits, i'm not sure there are
Like a previous post said.....android are coded to use all ram except the amount needed for system to run smooth, apps you open will then be stored in ram which are the fastest "sd card lol". Next time you open its from ram. If you use many apps its useful with much ram. After reboot you start all over again. If there's a memory leak you can get issues like lagging Best solution are to choose a profile with much ram for apps and not much more than nessesary for system
Our device gets better each day thanks to our amazing devs

Use guestekrnl 1.8.1 and enable ZRam, works a charm. See my recent post in the flix123 v20s thread as well.

What are you planning to do with the free ram?

Sell it on Ebay! :good:

To have more free RAM means it has to take some from the normally non accessible system dedicated RAM. This way your device has less RAM for things like graphics which can worsen video playback and record performance.

The opinion free ram is wasted ram is wrong. you should realize it from daily use. its because when you have for example 70MB free and you open browser with some tabs, some game, etc. it closes other apps you dont want or it closes some of the tabs in browser and you have to load them every time you switch them. you need enough free ram to open what you want without system automatic closing other and under 100MB really isnt enough

This doesn't make sense. The system will get you the ram you need whenever you need it.

want to enable swape ram in custom rom..

Hi guys,
i flashed zeus rom 6.39n two days ago
and tried to make swape file using swapper2
but always says fail...so it is supposed to be a custom rom
where every thing is possible
ao any help here ,,,

Swap is slow and your performance will suffer badly. Much better idea is to use memory compression from CM.

Use an app called swapper 2 in Play Store. Its free. Note that this worsens the SDCard Life.

As far as i know "swap" has to be supported by the Kernel.
And i think you dont need it cause there is enough RAM.

OB has a very weak RAM. Its 512mb is mainly eaten by Android. Leaving 200Mb+MAX left.
In average performance ROMs, it made OB leave with 160+ Mb
Sent from my LG-P970 using Tapatalk 2

Using the SD Card as a swap file is not a good idea. It's slow and will very possible make performance worse. In the KU5900 there is a partition for swapping on the phone itself and of course that kernel is built to handle it. The P970 can't be repartitioned to have a swap file on the phone itself, because it will make us lose space from userdata and we can't make the relevant changes to u-boot (We can make the changes to the partition header but then it won't boot ).
If RAM is a problem rather reduce RAM Usage by not having Widgets and not having millions of programs running in the background and use SuperChargerV6 that help a lot!

And that's not enough? I Think swap would'nt have a positive effect.
If that were so, there would have been someone implemented in its kernel.

Be careful with swapper, I used it and got perma-brick (the phone just didn't start, I could not enter s/w upgrade neither. I ended up paying 100 bucks for motherboard change.

i already gave away using swap because what i heard about its harm
and i use original mem parametars of zeus 6.39 and its sooo good
and play any apps in parallel so easly

[Q] CM10 Memory Footprint & Reboots

Hi,
I have a P1000 with CM10 (Humberos and Alroger) and I'm very pleased with this ROM.
It's such a difference if compared with GB that it really looks like having a new device.
There is one problem though that I'm not sure can be fixed: the random reboots.
I've dig a bit and apparently reboots are related to the lack of memory.
Analysing the available memory indeed I noticed that it easily goes around 50-70Mb which doesn't seem to be that much and probably this is the root cause of the random reboots.
I've enabled zRAM with a compression rate of 35% but this doesn't seem to have solved the issue.
So I'm wondering why nobody else is actually talking about this issue. Is the majority of P1000+CM10 users not having this issue?
Or it's just that we can't do anything about it and therefore we have to live with this?
In no way this post wants to be a complain. I'm just asking some more information to understand this issue better.
Cheers

Free memory is wasted memory.
This is not Windows which actively swap memory to swap.
if memory really is running low, the memory manager will kill inactive apps, not panic and reboot.

Hi Pryiana,
I'm not sure I got what you mean.
I'm not rebooting the system, it just does it automatically, that's the problem.
What I'm trying to understand here is why it reboots automatically.
Based on Alroger a solution to self reboots is to enable zRAM which is a kernel feature to compress data being written to memory to reduce the footprint.
Are you currently on a CM10 ROM?

I am on aokp jb using humberos kernel (forgot which date)
My point is :
the system reboots you are seeing, it is not because the ROM isn't providing enough free ram. It is something else. Maybe even because the memory manager isn't doing the right thing.
Maybe true that your attempt to free up more ram improves it, but it may just help to avoid hitting the real bug.
Anyway, I am not a dev.
Just a system guy.
I just want to say free ram is wasted ram.
In Linux systems, the kernel grabs as much ram as it can. Not free them.

OK, I see what you mean.
BTW, I can see from the cm10 thread that other people are having the same issue with the device restarting after a while.
Apparently 512MB are just not enough for Jelly Bean.

RAM Overclock

Would it be possible to over clock the RAM on our device? I know it's possible to underclock, we have seen that with the app 'Tegra Overclock' but what about over clocking?

Why would you overclock the ram? I see no reason for it as we have 1 GB Ram and that's enough for almost every daily task. This would only make sense for testing purposes I think.
Besides that I never saw anything to overclock the ram (because most of the times the CPU is the real "problem" of lag).

To speed up the rate at which the memory is accessed, thus slightly reducing lag, it's more an issue of quality over quantity because, as you put it, 1GB is enough for almost every daily task.
I just think that, for a system which needs to manage memory in such a dynamic fashion, an increased clock speed would be highly beneficial, and if it were only slight, I doubt there would be issues with overheating and battery consumption.
Anyway, the purpose of this thread is to question whether it is possible and how?; not to question the necessity of it.
Thank you anyway for your reply though Omario, much appreciated
