HTC devices and radio ram usage.. - myTouch 3G, Magic General

From what I've heard on the Dream and magic the radio has around 100 MBs of ram reserved... This is easily twice what I've seen on other phones. Does anyone know what this is about? I've noticed a lot of new android phones that aren't made by htc only have 128 MBs of ram, and I suspect that because their radios eat up less ram they'll actually have a usable amount similar to the dream and 32B magics. Why is htc using up so much memory for this? Could they change this in a update to the radio?

I would like to know...
But maybe some radio chips have their own memory, so no need to share main RAM

32A vs 32B

Hi guys,
I wanted to know which of these versions is better. 32A has more RAM memory, but 32B has better chipset, with 65nm technology, but same speed.
If I could choose, which one should I get? 32A?
Thanks you!
32A have the 7200A CPU and as far as I know it's a 65nm.
From the wiki:
* PVT32A handsets have 288MB total RAM (192MB usable by OS - same as Hero handsets) and use the Qualcomm MSM7200A CPU.
* PVT32B handsets have 192MB total RAM (96MB usable by OS) and use the Qualcomm MSM7201A CPU.

PVT32A should be based on 90nm architecture and PVT32B on 65nm.
I'm not sure if it makes more difference than the RAM size.
dun understand why htc used a poor processor for their newer phones?

I thought they are essentially the same processor but with 65nm technology (which in theory, should consume less power but not sure in this case)?
Speed-wise, is there any differences between the two?

Or why they reduced RAM size on PVT32B devices... They used newev chipset (yhbae01 is right - same speed but less power consumption, and a bit better performance) but reduced RAM...
Anyways, anyone knows answer to my question? Is PVT32A better than PVT32B, and WHY?

You also need to take into account the radio frequencies. As far as I know, the US T-Mobile devices (32B) have less RAM but run on the 1700/2100 MHz 3G frequencies, while the Canadian Rogers devices (32A) have more RAM but run on the 850/1900 MHz 3G frequencies.

before buy
Hi,
i am located in the EU and have the possibility to buy either 32A or 32B which supports my 3G network (only from ebay). i found that 32A-s are really rare and are about 1.4x more expensive than 32B-s. its that +~100Mb RAM so important it is worth to pay for? i am a little bit confused till i have read about the swap to SD possibility, the better processor of 32B etc etc. could someone experienced with magic give me a clear understanding on the 'real' difference of the 2 types (i know all the technical specs).
sry for my english

Speed wise I have never heard any discussion of 32A or B being different. Ditto for battery life. The RAM is a the big deal. Lets you run more apps without worrying about swapping. The phone definitely gets slower once it starts swapping apps in and out. If I had the choice I would get the 32A over the B.

Hi,
thank you for the information. So you think i would feel the lack of RAM on 32B... and what about 32A, will it run out of memory sooner or later, or under normal circumstances will it be enough?
thank you in advance

66 apps (assorted games, tools and productivity) and still have 213 Mb available. Apps with really big data requirements (GPS with local maps) tend to have their datasets on the SD card and many apps also use the SD for storage. So I would say you are good for Flash memory space. You could solve this with Apps2SD but most 32A ROM developers s don't see the need/demand.
In terms of running apps, you will notice a slowdown once the RAM gets filled up and swapping becomes an issue. Just install a task manager (liek TasKiller) and kill running apps that you don't need at the time. Once launched, apps continue running until you end them and most apps are designed without a quit/end function so they stay resident in memory.
Oh, C'mon! Doesn't anyone want to field the *real* answer?
If you plan on using a "stock" ROM without the HTC SenseUI, a 32b should be *ok*...
...but if you'd like the option of have SenseUI be lag-free (or more so, anyway) a 32a device is a better option.
Either way, how can you argue *against* the extra RAM?!?!
Here's an example:
I have the option of buy a new PC with either 4GB of RAM or 2GB of RAM...which one is going to feel "snappier" or more responsive?
Answer: the one with more RAM.
I've used a stock T-Mobile G1 to run SenseUI and it was *painful*. The ROM devs have made an insane amount of progress, and I'm sure that HTC has taken advantage of some of that.
I'm now using an HTC Rogers Magic (32a) on AT&T in the U.S...on which Sense runs *much* more smoothly...but I still prefer the Cyanogen ROMs, as they're more responsive still.
(it's for sale, BTW)

Well there is a little more into it than the Rom itself. How many apps and widgets you have running and how much ram consuming is the apps/games you're gonna use. I know that you have have task managers and so on but if i'm a businessman who need and want some apps to be running in the background constantly i would defiantly feel a difference from the 32a and 32b even when running a stock rom without sense UI!
From as far as I have read (hours of googling). both msm7200A and msm7201A are 65nm.
What I have read:
The A is 65nm and non-A is 90nm.
7200 is before the patent issue filed by broadcom and the 7201 has a patent issue workaround.
The workaround has a small performance impact from what I have read.

(p.s. sorry for the bump of this old thread, but I was googling on several overclocks of these cpu's and came across these details as well. So I tought it would be interesting to share ...)

RAM? WTF?

rumours say the ram is 512mb, others say 256mb, some say 192mb, tmobile.com doesnt say anything..
does anyone have an answer for me? this is a perfect phone, the htc magic with a flashlight, 3.5mm jack, and a keyboard plus it works with wind mobile in canada..
but i dont want a slow device, 32b magic boards are terribly slow with just 192mb and my 32a magic is pretty decent with 256..if this device has 600mhz processor with 512mb ram then it should be flying..
Thats part of the mystery. The phone supposedly has 512 internal, but a lot of it is used up by the Sense bloat, and by a lot of the TMobile stuff here in the States. Mine out of the box had roughly 150mb internally available , and I am down to about 100mb free with some apps installed.
With that said, this thing is still pretty darn snappy. And when 2.2/Froyo comes along, it will have apps2sd available, which will help increase your internally available memory too. I'd say to go to a store and check it out, you'll be surprised how fast it is.
Reviews are claiming this phone runs faster then all the other android phones out there right now. Even with all the crap you can't uninstall from t-mobile its still very fast. I have yet to experiance any noticable lag.
No regrets here, I am glad my mytouch 3g died
145 m available for programs after hard reset....at least that's what mine had!
Android System Info on mine says 419MB of RAM. In the Slide's owner's manual it says 512MB of RAM.

Well the 145mb is how much internal storage you have for apps. It does have 512 for RAM. If I kill all my apps that are running I would have 250+ of RAM free. And this phone flies. I might kill all apps once a day and the phone stays fast at even 60mb of RAM free. No worries.

i think the rom is colossal at 300MB + causing us to only have 150 free
im at 0 free no more apps unless i uninstall. and the phone still flys
The phone is snappy.

Yes i'm outta internal storage as well.need an apps2sd solution or root to remove all this bloatware.
RAM and storage are two completely different things. It has 512MB of both. Mine is showing 418MB of system ram, the rest presumably used for video, and the storage is partitioned into /system, /cache, and /data which is all that is usable for apps.

Galaxy S Ram and Himem........

Hi all,
I am getting this phone on July 21 when it's avaible through T-mobile. However, I ran across an issue while reading on the vast number of threads about this phone regarding the available memory.
1. Is it true the Android 2.1 is limited to 256mb of ram unless "hi-mem" is installed/enabled by the rom?
2. Is hi-mem enabled on the SGS stock rom? From my reading it doesn't appear that it's properly enabled.
3. If hi-mem isn't enabled, does that mean the SGS is functioning with only 1/2 of it's ram?
4. If so, how much free ram is showing on the stock rom and how much should we see once hi-mem is enabled?
I'm assuming that since many Android phones come with 512mb of ram these days, that hi-mem has been properly enabled on some of them. How much free ram does a typical android phone running 2.1 or 2.2 have after bootup?
I'm currently using a Touch Pro 2 which runs out memory all the time and would rather not have to deal with that on Android as well. I assumed that 512mb is supposedly to be more than enough to run 10+ programs at the same time should I choose to.
Thanks in advance.
It doesn't appear to be using 512MB I only ever have around 100 meg free. I used to have a touch hd and know what you must be thinking but i can assure you even with only 256 available it is fast and hasn't run out of memory on me yet. be sure to download a memory freeing app like task killer.
It runs quake3, something i could never get my hd to do with out practically killing the os
Kernel supports 512M RAM.
with the new Gingerbread specs it REQUIRES 512MB .. now if its 256MB , that's something to worry about

Don't worry, it has 512mb. It's just that some older kernels didn't support more than 256mb of ram, so the phone simply didn't "see" all 512mb.
My concern was that the kernel out of the box was too old to support the full amount.
The phone physically has 512MB of RAM. However, I think Android 2.1 is limiting the availability to 256MB.
Froyo 2.2 will correct this issue.

[Q] 340mb ram instead of 512mb?

My tw taskmanager shows only 340mb ram instead of 512mb, after some research I found that the rest of the ram is used for ramdisk,is that true?
If so,is there a way to use all of 512mb for ram?And does this make Epic inferior to Vibrant,Captivate and Fascinate or better?
All Galaxy S phones have 512 MBs of RAM. And I do believe all are the same. At least the i9000 and the Epic are.
The phone has a physical 512MB of RAM, but I don't believe that the stock kernel currently supports more than 340MB.

Check your built in taskmanager(by holding home button),it only shows 324mb total ram,so no they not all the same.Yes we do have 512mb but only 324mb(give or take few mb) is used for actual ram,the rest is used as ramdisk(cache).Vibrant and Captivate uses whole 512mb as ram and internal rom(hd) for cache,im not sure about original Galaxy or Fascinate.
Believe me extra ram not being available has huge impact on performance,i owned MT3gs with 512mb ram and 600mhz cpu and it felt just as fast as my Epic if not faster even with Sense.
This could explain big lag im getting with 4-5 apps open,i could have 10 apps open on Mytouch slide with no lag.

There is a reason why. There is no dalvik cache push to sd for our devices yet. If we could get an ext2 or ext3 or ext 4 for our sd cards and move the cache there, it would be a whole new ball game. But it's no availible for us yet
Maybe to balance the phones out because epic has 2 cameras and keyboard

I wonder if other models have same ram or they have full 512mb of usable ram without ramdisk,and does that makes epic faster or slower?
I know my MT3gs was way faster with stock sense 600mhz cpu and 512 ram(without sd cache),sounds like this phone needs that extra 128+ram because extra ram makes more difference than faster cpu,324mb ram I dont think is sufficient for 2.1 to run smoothly.Hope someone comes up with something so we can use whole 512mb as ram and internal rom or sd for cache.
The reason why we have only 320 showing is because samsung moved the cache there to prevent the lag some people here talkming about the galaxy s having.

EPIC FAIL ...325 for me :-(
2012 the Evolution of Human Consciousness
supposedly the GPU uses 128mb of the ram
All 5 galaxy s phones have 512mb but the epic and fascinate are limited to the 300 and something because our phones are the only ones that don't have a massive amount of internal sd like the others. We ours uses the more typical smaller amount of rom and the missing ram is used to stop touchwiz from lagging! Why do manufacturers and carriers keep ****ing up android!? Love this device but I can customize it myself just fine without the extra tw layer eating my resources and slowing my upgrade releases!

We have 512mb rom which can be used for cache,i have all the apps I need installed in /system/app folder and still have 400mb free,how much should be dedicated to android swap 128,256?So there is plenty of room and for those people that have about 100 apps on they phone they need to wait for a2sd.
Still no one has answered if its possible to use whole 512mb for ram,this phone really neads it,most of the time I have 3-4 apps open and about 80mb ram free-thats not good.Epic has fastets rom out of any model,now if we could use it for cache and a2sd for apps,plus whole 512mb as ram,than this thing would fly.128 for swap is a waste,plus I think that this 128mb actualy takes away from GPU's vram.
I agree that we need more RAM. There has to be a way to edit the kernel and get more out of our hardware.

576mb RAM?

I am wondering what is the deal with our HD2 (TMOUS version I have), supposedly our phones have 576mb of ram internally, but on every rom I have tried I am limiting to something much lower according to running services or quaddrant system info, I have flashed 2.15.50.14 radio which is supposed to have the 576mb of ram, from my understanding the phone shares 128mb of ram for video which leaves 448mb to use but I don't even have that according to running services. According to my phone I am using 90mb of ram and 292mb are free which is a grand total of 382mb of ram my phone has access to, where is the other ram?? I am getting really frustrated searching google and stuff trying to find answers, I know its a difference of about 64mb that I think im missing here but its the principle that our phones should have 576mb of ram and im over here getting 382 on every rom I try. Anyone have some ideas on this??
I would like to add that I just checked quadrant system information and this is what it says.
Memory:
Total: 421004 KB
Free: 172356 KB
Inactive: 46692 KB
Doesn't this mean about 50mb of ram is inactive? I don't understand the deal with that.
The missing ram is taken by the GPU.
Please reread my post completely, I think you missed something, I covered the gpu using some of the ram in my original post.
i would say those figures are 421MB total ram, 172MB out of 421MB is genuinely free, and 46MB is loaded with apps that have stopped but not been unloaded from memory.
Example, mine says
421004
80228
85188
i start a few programs and go back to quadrant, and it changes to
421004
85140
88916
As mentioned, the graphics chipset takes up 128 meg, and it grabs it before the OS has even loaded, so it never sees it, so you start with 448MB total. For some reason Android loses 25 or so MB, and so we all (tmous and regular) show total RAM as 422 or so.
As said the system and the GPU takes it. Come on do you think the guys who made linux would really be as stupid as to just leave out some ram for no one to use or for it not be used? Or any person who makes an operating system?
