Enable 57Mb RAM in ROM 1.66.405.2

Before anyone shoots me down by saying search etc - I have spent the last 30 minutes trying to find a straightforward answer to my query, to no avail!
I am sure there are others here (Noobs like me) that would like an easy explanation, so here goes:-
I have an Unlocked HTC branded HD2 on Virgin UK
ROM 1.66.405.2 (76641) WWE
Manila 2.5.19211619.0
Radio 2.06.51.07
448Mb RAM showing
What I would like to know is what Radio ROM can I use to allow my HD2 to have 576Mb RAM available?
I know I can reflash the whole thing with another 576Mb "enabled" ROM but I am quite happy with the ROM I have got?
Is my question unreasonable? Is there an easy & straightforward solution to my question?
Thanks for taking the time to read this - any help would be gratefully recieved.
BTW - this site is awsome!
Cheers

short answer ...... no. the extra ram needs a combination of correct radio and correct rom.

Hi samsamuel,
I just upgrade from v1.48 to offiicial ROM 1.66 707.1 (76641) WWE, Radio2.06. And I only got 448MB of RAM, how can I get 576MB of RAM?

You need the T-Mobile ROM and radio. Don't flash with the SD card method or you will be stuck on a 2.0 SPL.

you need a custom rom not an official one

you guys need rom 2.01 or newer and radio from the same rom.

Thanks mate! I see that you are running [ROM][WWE][1.2.10]PDAVIET-HD2 V14 (Core 28223) ★ OS 2.02.531 - are you happy with this ROM? I havent tried a cooked ROM yet, so would be good to get your input / feedback.
Would be nice to have the 576Mb RAM etc.

is there a difference in speed if u have 576 ram?

I have unbranded HD2 and it shows only 336.92mb. WTF ???

yes that is correct, the phone has 448mb of ram unless you use a custom rom/radio to unlock the extra 128, you are seeing the amount after space is used by the rom

Cant understand that. Where is 448 ? before custom rom or after ?

the 128 difference is for graphics, not the rom.the space the rom takes is 512 less whatever you show as total storage space.

haha sorry mate i change my signature once a year btw I'm currently using the new Touch X rom... no problem so far. To be fair a can't see any diference between having or not the 576mb because i'll never use it all. HD2 at its own is fast.

hehe, ok, here goes.
stock HD2 = 512 meg storage memory and 448 meg ram.
Of the 448, 128 meg is for the graphics, so your system shows 320 meg ram (336.93 meg program in your case)
when you unlock the hidden 128, you have 576, BUT 128 is still taken by the graphics, so your phone shows 448meg (454.81 in my case with the extra 128meg enabled)
when you flash a rom, and it installs windows and such like, it uses the 512 storage memory, (and i'm a little hazy on how much it takes up, and whether the radio is on there too, , probably is,) , , BUT whats left after the rom is in is your free storage memory. 180.23 in your case.
here endeth the lesson.

samsamuel !! GREAT LESSON !!!!
Bless you
Any way to have more storage memory? (not asking about clearing some exe's, temp or cache etc, and obviously not asking about SDCards )

Best and biggest way is to use a low profile rom. One that has a lot of stuff removed, and then you add the stuff you do use after.
I don't use many apps, and teh rom i use comes with just a few of the most usefull stuff, and while you show
Storage:
Total: 180.23
In use: 137.75
Free: 42.48
mine is
Storage:
Total: 262.53
In use: 80.3
Free: 182.23
Quite a difference!
Moving things like your cache and google maps to the storage card helps.

Anyway you could tell me the name ( and maybe links for) Radio and Rom that is the best to have more RAM and more Storage ?
ANd one's which dont have problems with:
SPB Theme
Sense for SPB
and S2U2
Cheers

see thats not only off topic but its also research you should do yourself for best results.
Theres a rom link in my sig, give it a try, i use it with radio 2.08, but one tip, read the chefs first 3/4 posts thoroughly, and stay away from sd card flashing.

[Q] difference 448 ram vs 512 ram on hd2

is there a significant difference between the two sets : one with 448 ram and one with 512 ram
will there be any difference in the outcome if i install android
1) on nand
2) on sd card dual boot with win 6.5
3) dual boot with win 7
i have used an hd2 with 512 ram and i have used android in all three condition mentioned above and i am really satisfied with the result. however due to some problem i had to sell off that phone and now i am getting another hd2 but with 448 mb ram. will it be a noticeable difference. please help to the earliest.

If you use MAGLDR to boot Android you will have 576MB of RAM But you will only have 512MB of ROM so you will have to use AP2SD so you will not run out of internal memory for your HD2. Also some Android ROMs have a version for the TMOUS (576MB of RAM) and a version for the EU HD2 (448MB of RAM)

Correction Both types have 576 ram, it is just hidden in the reg hd2,, running magldr (or clk I assume?) unlocks it.
The tmous versions of android roms are bigger, and don't rely on the ext partition, because of the double sized rom, nothing to do with ram.

This is a question I have been trying to answer for myself Sam. if you will take a look at nmy guide where i added the info on cLK (which I am using now). I put in there a little bit about I do not think it unlocks the extra128MB of RAM like MAGLDR does cause I can find absolutly no mention of a yes it does or no it doesn't. Matter of fact I can find no mention of the subject at all anywhere besides what I put in my guide.
So if anybody out there knows the answer to this question for 100% prof positive please chime in here.

i am sorry but one set has 448 and the other one has 576 ram
none of the mobile is of tmobile. so i guess it does not matter both are equipped with 578 ram and its just that one shows shared and the other one shows total where as that is also shared. am i correct ?

Get a stock regular hd2, as they ship from HTC, it has 320 total useable ram, plus 128 taken by the graphics chip.
Flash a tmous based rom (or magldr) and a tmous radio to that phone and it changes to 448 useable plus 128 for graphics chip, just the same as a tmous.

I am using a EU HD2 with android running off SD Card and when I open Advanced Task Killer, it says I have aprox. 250mb ram free, is this a normal amount?

[Dev] Andorid Leo - 576Ram

Hi, on my HTC HD2 i have a stock rom of desire HD. In the info of my device i see about 420mb of ram. I have radio 2.15.50.14. I think there is a way to enable 576mb. Probably the "issue" require a kernel that allow the rom to use all the ram. There's a patch or someone that can build a kernel with this feature??

HD2 has 448MB of RAM!

576 RAM = 448 + 128 RAM for sys/ video card / 3d accelerator

The 576 ram are already enabled but the system only shows 420 ( or 410 ) as its using the rest.

OK, last one time: YES it has 576MB already
(because trick to enable is: HSPL 2.08 + 2.15.50.14 radio)

wait... you mean the 576MB trick doesn't work with R: 2.12.x.x ???

well...maybe yes. the trick works with all radios that contain 50 (the 51 radios do not work) so if your radio is 2.12.50 it is OK
if you want some technical background: 2.xx.50 radios were originally released for TMOUS version of HD2 that shipped 576MB RAM and 1GB ROM
developers found out that the radios work on EU HD2 too and that it enables the adiidional MB of RAM that were initially blocked.
(the 1GB ROM cannot be unlocked because it is different chip)
all of this was a long time ago in a galaxy far away during Windows Mobile hacking....
in Windows Mobile there was about 350MB total (+ something system reserved leading 448MB of physical RAM)
later with TMOUS .50 radios it increased to about 450MB (+ something system reserved) meaning that 576 MB RAM is on all models.
so you can have 576MB RAM available because it is reserved for radio (phone function) and GPU
I hope that this old knowledge explains everything to all.
live long and prosper...
Daekin out

This is NOT a [Dev] thread and has no business been in this section.
@ OP
DO NOT post topics here unless you are a dev and are posting a dev project/ref. There is a general and Q&A forum for you.

Ok for me! Very good daekin! Number 1! Really sorry for the DEV thread...i only tried to start the dev of a new kernel. Sorry, close or delete thread. Bye

ram memory only 412 mb

I am using nand android, curently, sense of eclipse on my htc hd2 tmobile, and very strange to me is that i have so litle RAM, device is showing 412 mb totall, but my device has 576 Mb ram ?
Is there any solution to increse to actual size of RAM ?
sorry for wrong section

You should be actually posting this in Android QnAs, but thats not a big deal. The .50 radio that you flashed, only unlocks the 576 mb of RAM for WM. Mapping and editing of the kernel,zimage and maybe the startup.txt is required. Until now, the full 576 MB or RAM has not be available for use in Android. Only 448 MB or RAM is available currently, but that is if you add available RAM and system RAM. Your NAND build should be using the 448 MB or RAM. Currently, i presume either the devs are trying to get the full 576 MB of RAM, or its not possible. Firstly, getting the Android system to recognize the 576 MB or RAM would be easier if the device boots straight into Android. Secondly, this can most likely be available only on NAND. Thats all i can provide, as an answer to your question. You,me and probably most members out there know this is quite a big deal, to use the full 576MB or RAM,but the devs has not provided a definitive answer yet. Maybe we can wait it out and see...

Thanks , the answer you wrought was full !!!
Now waiting for solution, becose this android ROM that I am using, eats RAM like candy ;-)

[Q] RAM Unlock

I did my best and searched the forums, so forgive me if I missed this particular thread.
I've had this HD2 for quite awhile, and thinking of changing to another stock ROM.
I read somewhere that the HD2 actually 576mb of RAM.
Does anybody know of any ROMs that take advantage of the "locked" RAM? Or any awesomely fast NAND ROMs with Sense that has built-in OC functions (I saw a ROM that had 1.53GHz OC)
I just want to maximize the use of this awesome phone.
Any assistance would be greatly appreciated.

Flash dorimanx kernel. It supports 1.5 ghz

it seems impossible to unlock the memory
there are many oc roms,eg,dansta34's Runnymede Sense 3.5 android 2.3.5 OC daemon & HierOS 1.8.3 ker,however,you should know you do oc at your own risk

There are two versions of HD2

Confirmation please?
Someone with an TMOUS HD2 can please confirm this? Can you actually see the 576 Mb reported?

tmous has 576mb ram . Eu hd2 has less.

No, he meant RAM.
Check the website i posted...

As far as that was concerned, I heard the newer radios after 2.14 unlocked the extra portion for the system. I'm on 2.15. That was the case for the euro hd2's I heard awhile ago. Until the new radios stopped being updated.
You can check if your in windows mobile, just be sure your on the newest radio and you should show 576mb
Also.. http://www.slashgear.com/euro-htc-hd2-hidden-ram-matches-newer-us-spec-model-2871874/

android terminal, run "free", report back please

Everybody don't confuse RAM with ROM with processor speed...
Edit also : you could just search before you post. This is just way several topics below : http://forum.xda-developers.com/showthread.php?t=1350210

No confusion. For now, it states:
TMOUS : 1GB ROM, 576 RAM
EUHD2: 512ROM, 448 RAM.
Leave cpu clock out of this topic please

Tmous - 576
Regular - 448
Regular with a tmous rom and radio - 576
They do both have the same ram, only some is hidden on the regular, only unlocked in certain circumstances.
We all, reg and tmous, show 411 under android.

Looking at another thread... i think we're all mistaken.
Both devices have the same amount of ram. The total ram reported on WM65 was not queried via a command, but a simple file pretty much like we do on build.prop on android.
So, both devices have 448 RAM, and 128 GPU RAM.

That's better...
I was actually thinking that was probably it... like those crappy laptops or motherboards with shared memory definitions for RAM and graphics board ... still much more ram than my first one (256 Mb Apple iBook)...

Yeah, basically a Tmo-US is the same as the EU HD2 but with the 576MB RAM unlocked by default (EU needs a newer radio, from .14 onwards), 1GB ROM (as opposed to 512MB), a T-Mobile logo and red/green end call/call buttons (respectively).

just for the purpose of accuracy, its the 50/51 part of teh radio version that determines whether it unlocks the memory.
Any radio that is safe for tmous to flash, (and by definition work with android) will also unlock the ram on a regular hd2. Thats 2.07.50 onwards.
Any x.xx.51, or 2.05.50 and 2.06.50, radios will..
1 - brick a tmous
2 - not unlock the ram on a reg leo
3 - cause magldr (and presumably cLK too) not to start.
