The htc g1 came with as little as 75mb after an OTA it went up to 95mb....is it possible to crank up the ram space to maybe 400mb(that way roms will get faster)..... I know the reserved space is for radio and other stuff buh who knows we could pull something small in... Also can someone explain to me how the GPUs in smartphones work do the use a special video RAM? if yes How much of ours do u think it does use.?

It wasn't an ota for the g1 that magically gave in more ram, the extra 14mb of ram was stolen from the camera after a hacked up hboot was combined with another radio and put onto the g1, mind you none of this was meant for the phone rather ezterry is just extreamly good at what he does and was lucky to have such a similar phone to work with and JTAG experience repairing his phone so he had little risk of a brick. (Actually he was the first one to JTAG a g1)
Also the g1 had already been hacked apart so deeply that most ins and out were known and exploits were much easier to find. Such as patching a recovery to allow custom mtd partitions to allow for choice on how much space is set aside for system, data, etc.
Know that even with this you could just take so memory and just call it ram it needed to come from somewhere. So when a phone says it has 512mb ram available but you find only 375 usable that is because the rest is reserved for things like the radio, if you were to steal ram from some of these things well the wouldn't work well if at all, not to mention you wold need a great hack like the one ezterry did

I thought some RAM was stolen from the GPU as well, which is how come we got 109/ 110MB in the end (Also why 3D games don't work).
You are right on the .13d spl, that's where that ram came from, I was thinking of the ram hack for the donut roms back when the danger spl was the cats meow. Thanks for clearing that up!

is a ram hack even necessary? it certainly was with my G1 but this phone has much more ram that anything we might be able to free would be irrelevant

I'm with you. The reason I sold my mt3g and picked up the mt4g was mainly for the extra ram. The G2 has plenty, I don't really see the need.
If I recall correctly the extra ram came at the expense of graphics and 3d. Hardly a worthwhile trade off for a device that already has plenty of ram.

Ya they had that ram hack and they had the one that was with the new radio which just allowed for 14 more megs to be freed without losing anything

The new radio is different than the old ram hack.
If I'm wrong about this, someone please correct me.
The ram hack "stole" memory from gpu. (graphics)
The new radio/spl mapped memory that was previously unavailable in its entirety and gave us access to it.
Does that make more sense? The first is a hack/mod done by the devs here and the second is an upgrade from HTC/T-mobile.

The nexus was able to increase the ram by repartitioning its usage. Why can't we? Does anybody have a partition map saying how much ram goes to every reasource? I know 371 is not the max we can pull out.

I am an Eris user, soon to be DINC2 owner at the end of this week. I've been reading through the threads here getting ready for my purchase and it has been very informative.
I searched the DINC2 forums and did not see this mentioned. Has anyone tried zepplinrox' V6 Supercharger script on the DINC2? I'm not going to regurgitate his post verbatim, but it is a memory optimizer. It was introduced to me over on the Eris forums, in the GSB ROM thread. It really makes a difference on the Eris, but I'm not sure how much difference it would make on the DINC2.
http://forum.xda-developers.com/showthread.php?t=991276
He also has another script called 3G Turbocharger. This will probably make a difference on the DINC2. According to zepplinrox, "the 3g script reconfigures the build.prob and kernel to change the speed settings to a better enhanced setting. Think of it like a TCP optimizer on windows." On my phone I have noticed an increase in speed surfing the web, downloading apps and in other 3g activities. It may be placebo, but it does seem faster. If nothing else, I do plan to add this to my DINC2 when I get it.
http://forum.xda-developers.com/showthread.php?p=15948434#post15948434
There is also a Kernel Tweaks script on the above link as well. I am using it too, but not sure what performance gains I am getting.
Per zepplinrox' post, this should work on stock and rooted ROMS.
I am by no means an expert on this, so don't shoot me if this is in the wrong forum, not valid on the DINC2, or a repost. Just trying to pass along something that works well for me.
For now those scripts are useless for phone that came preloaded with GB 2.3.3.....no root no turbo.
This sounds interesting to me, I am rooted, would it work?

This wouldn't really benefit the Inc2. The Eris was a very memory limited device designed to run Android 1.5. Upgrading beyond this was pushing the Eris to its limits, and in some cases, beyond. Running newer versions of Android would make memory management more difficult because of the higher memory requirements and the very limited memory.
The Inc2 has one of the bigger pools of memory available for Android devices. It has 768mb of total RAM when many current generation devices are getting 512mb (others are either getting 768mb or 1gb). Unless you are running a LOT of background apps, or somehow managed to find apps that require massive amounts of memory, this is plenty of room.
What does it do? It tunes memory settings and task manager. That's pretty much it. It could have an effect on the Inc2, but I wouldn't really consider it a necessity.
Edit: BTW, my previous device was an Eris.
Well, Desire HD users with 768mb of ram enjoy improvements.
It even improves performance of an Atrix with 1gb or ram...
So it probably will help.
So "It tunes memory settings and task manager" is an understatement.
It revamps the whole memory thing

Actually, I think these will work without root. I think the only drawback without root is the scripts do not stick on boot so you have to re-run on each boot/reboot.

It may not, but zepplinrox posted above about the Desire HD with similar RAM and the Atrix with more that reported improvements.
Whether you use the Supercharger script or not, the 3G Turbo is definitely worth trying. Again, it may be placebo, but I think my up/download speeds are faster after the script. Here is a post with some info on speed improvements with the script.
http://forum.xda-developers.com/showpost.php?p=15959134&postcount=1139
I use the Mega memory option with the v6 script. I notice a huge difference in performance.

When I play games on my phone, one of the biggest issues I notice is the stuttering. On a desktop, it is typically an indication of not having enough free RAM, so the swapfile has to be used instead. Looking at the task manager reveals around 220 MB of RAM used out of 330 MB total RAM. That seems like it isn't enough for some of the games I play on my phone. I can't think of any other reason for the phone to experience the same issues when gaming, but I am far from an expert on phone operating systems.
So, which custom ROM running 2.2.1 or newer uses the least amount of RAM? I am mostly looking for RAM use after a fresh install, just after booting up. If there are some tweaks to increase available RAM by a large margin, those would be nice to know too. I'm thinking I probably just need a new phone if I want to play games.

I'd say Miui, go to that thread and download 1.3.5 and not 1.8.19, cuz that has screen flicker . Accelerometer doesn't work, but the ROM is so smooth.

Well, there's less bloat that can auto open or run in the background which seems to cause the reboots which seems to be the main culprit of the RAM leak.

After I updated my phone to 4.1 i'm only showing 1.56GB of ram in the task manager app. Has anyone else had this problem?
I did notice that I lost a large chunk of free ram... 4.0.4, I used to consistently have about 1 gig free, now I stay around 500-600 megs free
I've noticed this with any 4.1 rom with touchwiz and bloatware.
It's much better using a custom 4.1 TW rom (bacon!!) with some bloatware removed.

My take-away is that they did, in fact, use the extra 512megs for a new application that is part of the enhancement. My guess is butter.
Its most likely just the system using that RAM, like pretty much every android phone on the planet

Wow. Big difference. I'm seeing the same.
I never thought 2GB would get so low available so quick.
Who cares, really?
I'd rather have my 2Gb completely filled up as it's most likely just cached applications anyway.
If need be, this memory will be released anyway by Android's garbage collector.
On the other hand, history shows us that every new iteration of Android needs more RAM, so that's kinda expected.
My GS1 only has 512Mb which is more than enough if running Android 2.x (Eclair, Froyo & Gingerbread) but rapidly falls short RAM if running ICS.

free memory is waisted memory for some. I disagree when it comes to devices using a battery. Processes use memory and battery life...
I hate to see apps running in background even when I didn't use them since the last reboot. Self running apps grabbing infos about me suck. If Google dont want to stop these behaviors then its time for a new OS.

You got it wrong.
Cached apps in memory do not actually run.
They are just left there so that they can start more quickly the next time you use them.

RAM has to refresh whether it is used or not. The RAM has no idea if a particular bit is used or not.
The last ICS update also lowered the RAM to 1.59GB. I believe it has to do with how much RAM is assigned to the GPU. It is normal.

How come GSM Arena tells that the Desire has 576 mb ram, but, on any rom, it shows only 404 mb?
Is there any way to fix this?
I have seen some post with the hypothesis that a large piece of ram is allocated to the Android system, but I don't think that's true, because I can only achieve max 300 mb free ram, and the rest has to be busy with something...
don't know why it shows reduced either, but it doesnt really need 'fixing'.
assume that software developers generally know more than most of us here...
this might be an interesting read.
my recommendation is not to worry...check how your rom actually feels in day to day use. not how much free or total RAM you have or think you need, or what a benchmark score says...
