my DhD has 621MB Ram. I wannet to know Is It possible to add ram to DHD and increase its RAM to 1024MB?
Anything is possible. But generally speaking, no.

I mean is there RAM Slots like Computer or not?
Not physically, Generally mobile devices like phones and tablets have SoC (system on chip). Everything is built into one chip, including CPU, GPU, RAM etc. It is possible, however it is not cost efficient nor is it a do-yourself job Other possibility is diverting some of the RAM used by the GPU to be used for some app. This is a kernel thing. For example: if You use a 3D heavy app => the kernel dedicates 256MB to the GPU and 512MB to the CPU; if You don't use the GPU much, the kernel would dedicate lets say 64MB to the GPU (more than enough for smooth internet, but not with videos browsing) and 704MB to the CPU and system. I know it is possible, but haven't seen anyone do it so far.
PS btw why the hell would You need more RAM than the DHD has? Currently there are no more than 5 devices with more RAM.
Thanks a lot
there is not a an important reason to extend my ram.but i thought it's good if is possible

I just got the G2 and I love it. I came from a vibrant which was lagging and freezing and still had 2.1. Regret buying that phone. But this phone is a beast. My friend got the mytouch thinking it was faster.
I still think the G2 is really fast, but which processor is faster.
If you can explain in detail that'd be great!

Don't they have the same processor? Except the g2 is underclocked while the MT4G isn't?

HTC G2 uses the MSM7230 as compared to the HTC MyTouch 4G's MSM8255.
"MSM7x30, MSM8x55 and QSD8x50A - all 3 variations share the same design, differs only by the clock speeds. These 3 variations run at 800MHz, 1.0GHz and 1.3GHz respectively. Each of these features Adreno 205 GPU which runs at significantly higher performance level than Adreno 200 found in the 1st generation Snapdragon processor."

More than likely this means that the silicon on each device is QC'd to a different tolerance. IE the minimum possible speed. As everyone knows each silicon chip has a range and it will meet a minimum clock speed stable. It has been shown that most G2's can be OC'd to 1.4 ish. We don't have kernel source yet for the Glacier. When we do we will see if it is better or the same.
The MT4G also has more RAM. 768MB vs G2's 512MB.

More RAM doesn't directly translate to more speed.
More RAM very nearly directly translates to more speed for 99% of usage time because there are less reads from flash memory. I don't know how noticable it would be though. Certainly not the marked improvement seen on PCs with normal hard drives.
yes but the sense ui takes more cpu/ram to run smoothly. atleast in theory. plus the mytouch hasnt been oc'd yet so we will see.

You are wrong.
The more RAM means you can load more stuff in RAM. Example in PC, You can open more Internet Explorer window.
But the speed is the same. Example.. we kill all background apps and both G2 (1ghz) and MT4G(1Ghz) will just run quadrant alone.. they should perform the same since the speed of their RAM are equal regardless of the amount.. example 512 vs 768.
The MT4G needs more RAM because the Sense UI is composed of useless bloatwares.
Na, MT4G won't run faster, but it'll be able to run more stuff at the same time.. like people above have explained.
But I really don't think we need that much RAM, currently.

true. but honestly, the only moment where you might be able to notice a slight speed difference is with numerous, and i mean a hell of a lot, of apps open in the background without killing them
Greetings all. Allow me to introduce myself and explain my noob credentials before making my main point. I am an electronic engineer by day, and I am not a software person - assembler is as high-level as I am comfortable programming. My phone hacking credentials extend only as far as rooting and unlocking one galaxy S, and installing cyanogen 7 on a ZTE Blade, another Galaxy S and my personal Defy.
The blade was the first cyanogen install I did, and I did not find it to be spectacularly fast. However, on a 600MHz processor, was I expecting too much?
Next up was my defy. Oh my word... This is absurdly fast, as we all know. My phone scores 2100 in quadrant (for whatever that is worth - we know quadrant has its flaws).
Finally, I installed CM7 on a Galaxy S, and was marginally disappointed. Yes, it was a bit slicker than touchwiz, but not much. Quadrant of 1615, despite the significantly greater 3d capability of the SGS over the Defy.
So, some questions in my mind - Why does the Defy benefit so much, and how does it end up significantly outperforming the SGS when on paper they are pretty even with a slight advantage to the SGS - both 1GHz, both 512MB RAM, SGS has SGX540 and lower res screen (fewer pixels needing fill rate can potentially improve graphics framerates).
What it comes down to, I believe, is the RAM. The SGS has a strange memory architecture for its 512MB, with 128MB as "onedram" offering ~10GB/s speeds, required by the SGX540 and apparently solely dedicated to it. The remaining 384MB is LPDDR (1.6GB/s) and is what is available to the system (with CM7 reporting 342 total in about phone).
In contrast, the defy has 512MB LPDDR2 (3.2GB/s), which is all available to the system with dynamic allocation to the GPU when required. CM7 reports 477.
Therefore, in situations where the GPU is not being heavily used (which is most of the time for general system use) the Defy has much more and much faster memory for the system.
So it seems that the key for CM7 performance is memory speed and capacity, not necessarily processor power.
Should ICS come to the SGS with GPU-accelerated UI then I think the SGS would suddenly have a big advantage over all other single-core phones.
Quadrant Score for CM7 on the Defy is absolutly not relevant.
I should not use this as point of comparison ... not at all.
Does your Defy run slicker than your GS2 ? Does apps run faster ?
Do you have same settings on the both device ?
It is an SGS (i9000), not a GS2 (i9100).
Yes. The defy does seem to run a bit slicker and more fluidly than the SGS.
Also for me, defy + cm7 is way better then my ex-dhd....

LauncherPro and browser opera use gpu for its work. If you are right, sgs would benefit greatly by using those instead other cpu based.
Hello @ all,
as you might know we have only 343MB of RAM available to the user on our Arcs, but we have a total of 512MB RAM.
I did some research and found out that the most phones with 512MB RAM have 370-400MB or even more RAM out of the 512MB available to the user.
I know that there is something reserved for the system, but normally it's less.
But sometimes I'd really like to have a few MB more RAM available when I do multitasking or a lot of stuff is running.
So the question is if we can unlock more RAM for us and an even better user experience? And if yes, how to do it.
Regards,
Flo
May be a mix from a swap partition and the supercharger script is the right for you
The supercharge script optimize the memory management of android
Already have SuperCharger V6 installed.
Does a really great job and fixed the problem with LauncherPro Plus redrawing often.
But still I'd like to have more RAM available...
For example the X10 with 384MB has ~280MB available, so we should have ~410MB available on the Arc. And not just 60MB more...

No you can not unlock the RAM or ROM for further use, you however can optimize it by using external scripts and the reason for 343 megs being available is because around 150-170(approx) megs of RAM is being used by the graphics (GPU).... u did not account for that now did u... . Now maybe just maybe u can use a custom made kernel to squeeze some more juice out of the RAM...but no major RAM increase
Ah, okay.
But somehow it's possible.
Today I saw a review of a custom ROM on youtube for an Evo 3D...
And other phones with the same GPU have less memory reserved.
E.g. Desire HD, Desire Z
Strange that SE reserves that much

Your phone reserves memory for hardware, camera for example. It works the same way as reserved memory for integrated graphics on computers. We have HD recording in the arc now that has to come from somewhere, and just where would that place be?........the RAM. SE has tried very hard to squeeze in some very good features into the arc and that's why I guess they made a trade off with the RAM, and all these features require RAM and its not a luxury that SE has to reserve all that RAM but a necessity so we users can enjoy some great HD recording and amazing resolution.
One more thing even though the Desire HD and Xperia Arc do share the same processor (MSM8255 SnapDragon) the HTC Desire HD has 768 MB RAM and 1.5 GB of internal flash memory data storage and the Desire Z on the other hand uses a MSM7230 SnapDragon even though the GPU is the same the processors differ the MSM8255 is 1GHz and the MSM7230 is 800MHZ and in the overall equation of memory reserving other than the GPU the CPU has its part to play too and a very imp one...hope ur getting the idea and the GPU in the MSM8255 is a marked improvement over the GPU the 'Z' has. Now even though HD does have lesser memory reserved its not that big a difference. However on the arc, the camera is way much better than on the HD (camera-->RAM) so SE has used some more memory for better features.
I think everybody want to have more ram and more ram
but only thing that we can do is tweaking our system again and again.
I´am for example using the supercharger v6 option 4 and a swap partition and its great to see some improfment
I am looking for tweaks all the days but i am not so good in android so it need time
Ok, then.
If it has to be like that...
Just want to get the optimum out of my Arc.
Maybe a dev will come with a kernel that unlocks just a little bit more with keeping all the features

Hi guys
Quick question, i see that specs show the nexus has 1gb of ram.
But my ,"system apps," so it only has 632mb can any one explain?
Thanks
I think that some of the ram is reserved for the gpu. That's why you see less ram.
Just wanted to make sure
Still thou 400mb on gpu?

I was in looking at the Rezound and did a hard boot and checked available memory. It only had 250Mb of the 1 G available. The rest must have been taken by Android, Sense and whatever bloat Verizon is loading.
Have a quick look at my screen shot - ( if they work)
I beleive that is should be 1GB of Ram, i understand if some is used for system processes. but 400mb.... far to high i would think.
Any one care to explain?
Some is reserved for the OS to function at all times. Some of it is reserved for the GPU, and radio to use. It is done this way to ensure you have the maximum needed for these to run.

That makes sense.
Nothing is reserved for the O/S, that uses whatever is available. It's probably for the GPU, same as the Nexus S has 512MB, but only 384MB available due to the GPU being allocated 128MB.

This is something to do with RAM. The longer you used your phone, the more RAM is consumed. Now don't blame Sony for bad RAM management, all Android kinda suffer the same... except higher ends have more RAM which helps those phone snappy.
IPhone on the other hand can literally outperform 2 or 3GB RAM Android smartphone, why? It's because Android chose to use a 'garbage collection' solution for memory management. Well it's not something bad if you have enough free RAM and is actually quite an efficient memory solution, but as the RAM usage increases, the performance drops dramatically and thus explains you're Xperia M to lag. IPhone uses another solution for memory management which is far more efficient as compared to Android's.
