I have a raph500 and all the forums say it has crippled ram and in my eyes crippled means its there but you can't use it so i browsed the net and found this info here
pdadb.net/index.php?m=pdacomparer&id1=1389&id2=1311&id3=1386&id4=1547&del_id=1389[/url]
it says the raph500 has 192mb and only 113 is usable
and i also read about the XIP and how it controls everything including ram addresses and blocks so i was wondering if it is possible to get that info from the XIP on the phones with the same ram size (raph100,raph110,diam400) and put it in for the raph500 to use the rest of the ram i dont have the knowledge to do this to try it out its just an idea that makes sense if some one finds a way to do this i am willing to help any way i can
sorry for the lack of grammar
It is crippled because everyone else has 288 MB RAM. Usable RAM is Base memory minus OS Load = Usable. For example, on my TP2 I have 288MB Ram ... System steals 100 MB, leaving 188..... open processes use 90 so I have only 98 out of 288. You would only have 6 MB free in this same scenario. Hope this helps.
question
first off i have touch pro verizon and i'm trying to find some or some way to uncripple my phone if possible. i have raph 800 (i believe) and its unlocked and where can i get raph 500 so that i can put it on my phone and what is the difference be 500 and 800.
Touch Pro and Touch Pro 2 are all the same guts (288 MB RAM and 528 MB ROM)
You cannot "uncripple" your phone. Sorry it is just the way Verizon ordered them from HTC.
RAPH 800 (288MB RAM) is the sprint touch pro. RAPH 500 (192 MB RAM) is Verizon. So you already have a RAPH 500. These device codes are specifically different varieties that HTC makes per order of the Telecom Company...... nothing you can do to change it.
Sorry, but your only option for a fast system is to find a Light Rom. You may want to check out Lunacie on PPCGeeks. He makes a pretty good light rom for the Touch Pro.
is it possible to have raph 800 on a verizon phone?
not anymore. Used to be able to have verizon re-program your ESN..... but they wont do it anymore. If you used some creative web searching, there is also information about *faking* certain information to get a sprint phone on verizon network. (or you could use any other CDMA carriers phone.)
i have a phone from 08, but you said that its not possible to do anymore?
Please see above comment about "creative searching" if you look on either google or this site about changing providers and keeping your phone, you would be amazed what you can find.

One thing that's always nagged me about (most) HTC devices is the low available program memory. I mean these are 64M devices and despite the determined efforts of our best chefs, we're lucky to see 31M of available RAM on a clean boot.
I've seen screen shots of Treo 700wx devices and they seem to boot up with over 45M free. Impressive. I hear the Treo 750 doesn't fare quite as well but still much better than the Hermes, Wizard, etc.
So two questions: what's using all that memory on (other) HTC devices and how does the Treo manage to use so much less?
PalmOS most modern devices use only arround 10mb of HEAP, the rest of the memory is for storage only. So, that means they can run an app that require more than that amount of heap, even if they got plenty of ram free. It's a very eficient aproach but more limited than the ppc (pc like) memory management.
I know all about PalmOS's primitive memory management. It's one of the reasons I gave up on them.
The Treos I mentioned are the WM5 versions though. Both are speced at 64M of RAM and both boot with much more available RAM than even our most carefully cooked ROMs.
Question
I have the official AT&T Rom what can I do to free up some more RAM I got 7mb free right now?
is it possible to upgrade our hermes to 128mb of ram??
anyone done it yet?
I've seen somebdy changed in China..
I ve seen a thread in my home's forum, and the key of RAM upgrade is that we must find a technical manual for Hermes' original RAM and the RAM series that will be supported by the mainboard. If u've done this and have got a RAM chip...do it.
Na, i've found the thread.
I'll translate them into English line by line
I placed a pic of Hermes' RAM in attachment.

HTC Hermes （CHT9000）系列的产品采用的是 三星 K5D5657ACA-D090 估计可以换成同品牌型号类似的字库 ，至少 HTC 公司内部有人就成功了
HTC Hermes uses product of Samsung K5D5657ACA-D090, and it may be replaced by the same product. At least we have some successful examples from a staff in HTC.
Samsung K5D5657ACA-D0900
The K5D5657ACA is a Multi Chip Package Memory which combines 128Mbit Nand Flash Memory and 64Mbit synchronous high data rate Dynamic RAM. 128Mbit NAND Flash memory is organized as 16M x8 bits and 64Mbit SDRAM is organized as 1M x16 bits x4 banks. In 128Mbit NAND Flash, a 528-Byte page program can be typically achieved within 200us and an 16K-Byte block erase can be typically achieved within 2ms. In serial read operation, a byte can be read by 50ns. DQ pins serve as the ports for address and data input/output as well as command inputs. Even the write-intensive systems can take advantage of FLASH¢s extended reliability of 100K program/erase cycles with real time mapping-out algorithm. These algorithms have been implemented in many mass storage applications. In 64Mbit SDRAM, Synchronous design make a device controlled precisely with the use of system clock and I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable burst length and programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications. The K5D5657ACA is suitable for use in data memory of mobile communication system to reduce not only mount area but also power consumption. This device is available in 107-ball FBGA Type.

is it possible to get the chip from other htc model?
i have a number of bricked htc himalayas, blueangel, even universal.
what about from hard drive? or computer ram?
Could you post the link of your home's forum here? Cause I am very interested in this upgrading for Hermes!
By the way, I can read simplified-Chinese!

you may not read this thread until u've got ID.
Problem is, because this is an FBGA type chip, it's a PITA to remove and resolder. You really do need special tools for it.
Since TYTn II is the upgrade of CHT9000, could it be a reference?
Since TYTn II is the upgrade of CHT9000, could it be a reference?
I think we need to prepare at least three things:
1. We need to know if the design of the motherboard can support 128MB RAM;
2. We need to know which IC can be used in CHT9000;
3. We already have ROM that can support 128MB RAM.
I mention TYTn II is beacause we may get imformation from it about point 1 to point 3.
Suppose we can use the same chip that TyTn II is using, we can take a risk to do the upgrade.
BGA packaging is a royal arseache to try and do manually, infact im pretty sure its not possible using traditional methods, we are talking pick-n-place reflow soldering here, not using an iron.
I think, samsung processor cannot address more than 64 MB RAM.Some one posted this already in this forum.So as of now it is not possible
mission impossible

.. additionally it would be even harder to remove the RAM and FLASH MultiChipPackage from the Samsung MCU.
The picture shown above is the MCP for the radio chipset!!
Have a look at the detailed user manual.
... think wiki link to this manual does not work anymore???
P.S.: if someone's interested i may upload the manual

Anyone capable of doing such upgrade??? guys Mogul needs a memory boost to be an ultimate device. it must be possible to preform a Ram upgrade lets brain storm this and make a step by stem mod chip like mod or even some one could start a service perhaps.
what is needed......

Someone with intimate knowledge of the memory map and microcode for the Qualcomm processor inside. This person would have to determine if there is sufficent address space above or below the existing RAM and impliment it in a new firmware flash. I am wondering myself if the reason for the small RAM might be that there is or was no address range available for it, or just maybe short sighted designer decided that this was all that would be needed. If the latter is true then it would be possible. Lastly I would mention that a really good station and tech would be required to change out the RAM for a larger chip, assumeing that one existed in the same package. Might have better luck doing a RAM based add to the microSD slot by adding to a custom engineered card. If someone did that then the applications could be mapped to addresses that already exist and are known. You would end up with a microSD card with maybe 4 gigs of flash and a few gigs of RAM ??????? That might be easier. Food for thought.

Hi Guys,
I recently looked under Memory in Settings and found it was showing only 448MB of Total RAM. AFAIK TMO USA HD2 has 576MB of usable RAM. Am i mistaken, or is it same for everyone.
I have the NRGZ 20th Dec Cookie 2.0 ROM flashed on my phone.

448MB is okay and normal.
448 user ram plus 128 graphics ram = 576 total ram
ok got it thanks guys
who told, that the missing 128 megs are dedicated to the gpu...? this seems to be a bit too much for me, especially if compared with the rest of the specs of the adreno unit...

128MB is use as graphics
Just wondering...how much RAM the original HD2 had? It had 448MB right?
So was it like 320+128?
yep, it's "public opinion" that these 128mb are reserved for graphics; but who wrote / said this, what's the source for this "fact"? can't find anything, neither here nor in www.
i'm asking this because i can't believe, that this amount is reserved for gpu only, as it seems way too oversized for a gpu with the capabilities of the adreno. in my humble opinion 64mb are too much, too...
Could it be a case of bloated specs by tmob?
go read the spec sheet for the snapdragon, particularly the graphics capabilities, the triangles per second and what not. that's why it needs the ram.
Hello;
I recently purchased a 512mb version of the G9 on sale thinking it would be 1gb; turns out after installing ICS that it's still 512mb. Now I'm trying to decide whether I should keep it or return it and spend $60 more on a 1gb version.
Has anyone used both the 512mb and 1gb and noticed a difference? Should I keep the 512mb or spend more money to upgrade?
If you have any recommendations please let me know; thanks!
I had bought the 80 Hdd before with 512 mb. After a fault Archos replaced it and to my surprise it had 1.5 ghz but still with 512 mb. So I got a bump in cpu modele. When the 1gig ram came out I ordered and returned a 101 hdd with 1 gig ram for the same prices I had paid my G9 80 before.... I had to decid which one I keep...I liked the G9 80 better even with the 512 mb.
Personally I did not see anything better on the 1gig of ram. May it's the way I use the tablet. But for me I think 512 Ram is fine. (it's not the 250 from gen8)...
no big difference...
i have the twice
I find that applications persist in the background better, for example, the web browser doesn't have to reload tabs when returning to it so often. The launcher never has to reload when doing something memory intensive.
Other than this there is no real difference (speed etc.)

I only have a 1.2Ghz model but if as a example were to compare a Galaxy Nexus to a Nexus S the background performance is huge!
Sent from my ice cream powered Nexus S
I have a memory manager (for manually freeing up old apps) on my home page displaying how much free ram is available and on average it shows about 350MB free. That tells me that the quite a large portion of the 1GB ram is indeed being used and also that the 512MB would most definitely need to swap more often. How that translates to performance however is another question as depending on the apps used, swapping might not be noticeable at all. Only having the two side by side with duplicate setups and performing the exact same actions would be definitive, but hazarding a guess I would say the 1GB should outperform the 512MB in most cases where many apps are opened. Again, that might or might not be a negligible difference..
