actual 576mb performance increase?

Probably this is a an old topic. I've read numerous post on weather this 576mb is real or just a trick and the logic behind it. Now it seems this is indeed a real thing but I couldn't find a good post comparing the increased ram vs the old one.
My question is does this actually improve the performance? If so, how come some chef here are still cooking not utilizing the increased ram? Or is it like many have said that releasing the hidden ram actually slow down a little due to the fact this "hidden" ram is exclusive used by certain process to speed up the system overall?
thanks

Well it doesn't increase the preformence since the 448 mb is al more than enough. It actually decrease the preformence a little bit but that is also depending on rom. So its only useful when you 15 apps running that together is using more than 150 mb of ram normally that never happens. So the hole trick is only useful for
-very very exclusive situations
-To show your friends he you see I got now 270 Mb free.

How come it decrease the performance?

I read somewhere on this forum that theextra ram is allocated for some graphics usage, and i think that this is what he means...

has anyone actually done some sort of bench mark comparing the increase ram vs stock one? Graphic test in particular.

No difference to minimal difference in graphic performances from user experience. It's not noticeable.

no the graphics 128 is already taken before the OS alocates the rest. You cant touch the graphics 128 even with the 576 hack.
When 576 is enabled, you still only have 448 to play with, just like when it is not enabled, and you have 448, you only really have 336 that you can use.

Based on what you said, so the 576mb hack is really just displaying the numbers out? With this hack, even it shows 448mb available, you will get maxed out after 336mb. Is this what you are saying?
There is a thread some one made a 448mb page pool and HD2 can still boot up. Doesn't that mean the 448mb can be used freely if needed?

no, what i am saying is if you get a stock hd2, and look at the hardware info, it will show 448MB Ram total, and when you look at total program memory, it will say 336 (or there abouts)
Thats because there is 448 MB Ram, and 128 is taken by the graphics, leaving 336 for the system to use.
In contrast, if you activate the 576 hack, in hardware info it will show 576MB, and in total program memory it will show 448MB for the system to use.
Again, this is because the graphics takes 128MB

I just want to ask u all who think 576 is a trick a question, why do all the chefs here enable 576 in their roms? Are they not smart and intelligent enough, than most of us, to know that 576 is not a trick?

You have to use one of the T-Mobile US Base Roms and use certain radios to enable the hidden ram. Some chefs may use different base roms. It's not really a matter of deciding to enable it or not.... it just depends what base rom they want to use for their rom.

About that decrease wgere I am talking about it is something that windows have to adress more memory. Thats why it is slower. Well actually it isn't a very huge decrease.

Smaberg did create some rom with new base but have 448ram.
Let me quote some for u to read:

After doing some research I have found out the following information :-
Windows Mobile 6.x is powered by Windows CE 5.2.
http://www.slideshare.net/abhisheksharma/windows-mobile-6
http://www.addlogic.se/articles/articles/windows-ce-6-memory-architecture.html
The memory architecture is divided in to 32 process slots. Each with a capacity of 32MB. However with a little testing of my own I have found that it is not possible to run more than approximately 11 applications similtaneously which equates to 28 processes running on my setup. The remaining (28 - 11) 17 processes are operating system specific processes such as the GWES.exe DLL's etc.
If you calculate the memory required for the max of 11 applications it is 352MB which explains why I never see the memory go above 300-330.
The advantage of having the extra memory (576MB) is possibly to allow the other 21 processes to run with more head room.

i am going to clear this up once and for all
1ghz hack = fake
576mb RAM = REAL as conclusively proved by advanced testing when it was first discovered, the fact that it comes as default whena tmous rom is flashed on a EU hd2, and my own testing (i built a rom wiht a 400mb pagepool and was able to sucessfully fill the remaining 50 odd mb of ram before the system gave out)
end of story

you're probably on a ROM whose Chef has chosen to differentiate their ROM from All the other ROM's whose Users actually benefit from the 576MB RAM that's there...
How do ALL the Chefs who Enable 576MB on their ROM's know this is NOT a trick? (Aside from the fact that there is nothing changed in the Registry to "Show" 576MB)
We tried creating a Pagepool of 448MB (on 576MB ROM's that's what's left after the 128MB is allocated for the Graphics etc.)... As you know, increasing the PagePool decreases available RAM...
by increasing this (PagePool) to 448MB, the ROM should not even Boot if the 576MB RAM is a "trick"... but it did boot... slowly and sluggishly... but it booted.

I am definitely believing the 576mb is real and just want to know the performance difference and reason why HTC wants to hide this part of ram

there wont be a performance boost. Putting more petrol in a car doesnt make it go faster, and likewise more ram doesnt make a machine run faster UNLESS you are already maxing out the available ram, which none of us are.
Personally on roms with the hack, i use the extra memory to run a ramdisk with opera and system cache on it, and that gives a few benefits.
1 - when you soft reset it is wiped and rebuilt, so your cache folders dont fill up all your rom.
2 - Opera especially definately seems to run faster with the cache there. (especially compared to using the sd card for opera cache)
3 - you arent using rom or sd card space for teh cache folders.
as to why it was hidden, , , who knows? there have been a few tentative reports (nothing confirmed) of more echo/sound distortion in calls using the hack, so perhaps the radio utilises it? (I dont believe this myself, i see no difference between with/without 576 roms, but it has been put forward as a theory once or twice)

@ above me yeah that is correct
Maybe in the beginnning they got issues with it and they wanted to release it fast so they decided to give it 448 mb. This is very good possible since first roms only contain 320 mb of ram. Later they found out the bugs so the TMOUS version could released with 576 mb.

[Q] Increase RAM with flash memory on defy

hello,
im using Motorola Defy MB525 with cm9 4.0.3
my q is, can I somehow increase the RAM with the sdcard memory (like create something like virtual RAM or something like that) to improve my phone performance ?
it preety slow because it still Beta and i want it to be fast as cm7 so i thoght it may help.
anybody tried it before ?

You can do it by swap, but you need really good sd-card (class 8 or 10), because it can slow down your phone.
Don't you have enough ram?

unfortunatly, i think that its the only way to speed up my phone, becuase i wont take the risk with oc above 1000Mhz
its this or wait till cm9 will be official for defy and hope it will be faster, one of the two.

+1 to the idea was thinking about it the other day
Would a 32gb class 10 work and partition a gb or two? It is complete overkill to the size of ram but I think a gb would be quicker than our 500mb as system steals about 250-300 minimum
teamwork makes the dream work

If someone can do this with a 32 GB class 10, can you please share with us ? I am very interested. Thanks!

We cant do swap... our kernels dont suport it...

now cm7 can swap

More and more ROMs support swap, but unless you are willing to sacrifice a good Class 10 card for it, most people don't want to use it. Because SD and NAND are not meant to be written and read from as much as RAM, it can break down.
Use CM10 ROMs or GB roms, they are much superior to ICS in memory management imho.

I have teh same problen, not enough RAM in CM7 Defy.
It can slow the phone.
can i use some memory swap with my 32gb c10 card?
Or i use an memory killer, like CleanMaster?

I recomended use memory killer, because you can screw up 32gb 10 card (c10 cards are expensive).

RAM Usage high

Hi,
I recently moved from Note 2 to S4. With my Note 2, I was able to freeze apps with TB to a low 390-450mb used. I was curious why the S4 uses almost 1gb most of the time and I was only able to knock it down to 800mb used with freezing some apps identified on other threads.
Thanks!

I am also curious about this and I also switched from note 2 to s4 but im just going to guess because all the extra features it has and upgrades anf even if some arent in use they are probably on standby still taking up some ram, idk thats just what I think?

There are more sensors on the S4 and thus more services required to run. If you missed freezing them they will eat RAM, and if you freeze some you will threaten stability. If you aren't sold on the stock ROM then try something from ASOP. Or some of the fully debloated TW ROMs like GOLDENEYE.

Why do you want free RAM?
This is Android, not Windows.
You want Android to use RAM.

So high usage of RAM is good and won't slow down processors or heat up?
Thanks,

I don't know why you'd think it would heat up the processor, it won't.
While low ram isn't necessarily a bad thing with Android, linux based systems tend to use all the ram it can to speed things up,
With all of samsung's bloat it can slow things down if samsung bloat is taking up memory and you don't have enough for the active apps you actually using as the samsung bloat tends to stick around in ram even if your not using it.
Installing cleanrom (TW debloat) seems to have freed up some ram and things are running smoother than stock.

RAM does not heat up like a processor does, it will warm up because it has an electric current going through it, but it will not heat up more based on utilization.

Thanks for the info. Ill just leave it alone

how to check weather a rom has good ram optimisation or not

Currently i am using ressurection remix which is pretty good but after closing a app the ram remain still occupied and doesn't become like it was before opening that app. please tell me which rom has best ram optimisaton

and for what you need free ram? If system or app needs more ram it will free it by himself, if you want install greenify and greenify apps, but for sure you don't need a lot of free ram.

Suppose I restarted the phone my ram consumption is 1gb then I opened 10 apps now my ram consumption is 2gb then I closed all the 10 app but still my ram usage show 1.5gb or more than that..I want to know why

sometimes, even you close an app, part of it stay in memory for future use of this app, sometimes *system* ram usage increases throught your using of phone, sometimes other apps increease usage too

Thanks. And please tell me how to judge a ROM weather it has a good ram management or not

I havent seen a rom with a really bad ram management here for our Bacon all the ROMs are based on one of the 2 'sources' we have. I wouldn't worry too much about it just enjoy the great roms
Verstuurd vanaf mijn A0001 met Tapatalk

If there's memory leak in the source, it will be there in all the derived ROMs. But you need not worry about it. Sources are quite stable and memory management must be equally good.
However, it can be a bit different on suppose an AOSP based ROM vs a LineageOS based ROM. This is also very kernel dependent. You should try them out yourself and see! Good luck.

Redmi 7A - 64 Bit Rom available?

It has a 64 Bit CPU but only runs 32 Bit. One app I use runs only on 64Bit Android systems. Is there a custom rom available?

im also looking for this

I have a feeling we play the same game. And yeah I need this answer as well. From what I read it is possible but I have no idea if one exist.

No, most likely it will not be in the near future, because there will have to redo /vendor.
