256MB RAM for Uni - Is it Possible?

Hi!
I have upgraded my Uni with 128MB RAM. I understand that there is extra provision for additional RAM on UNI. Can anybody confirm that the two 64MB RAM chips from Blue Angel can be used on the free space available on Uni and can it be upgraded to 256MB RAM.
Feed back and guidance needed in this respect.
Regards,
Haque

People seem to be saying it's not possible. That 128MB is the maximum. However I remember being around in the forum when people were saying you couldn't upgrade to 128MB and others found a way to do this.
I think this would need a reply from someone who knows the hardware better. (Me, I'm still wondering what the two blank spaces could be used for... and for when someone builds a small GPS chip that can be plugged somewhere inside my Uni!!... dream on!).

Those blank spaces are for GPS chip, which HTC didn't include. You can install the chips but it will not work because a radio rom with GPS FW has never been released for Uni.

Damn, I saw that Tomal replied and hoped that I will come to this thread and he'll say something along the lines of 'Yes, we successfully installed 2 128Mb RAM chips and I am testing them now with a new ROM, will let you all know how it went and offer an upgrade to people who want to get one'
Even my Elf can pinpoint my location on Google Maps, my Uni can't. Outrageous

Some time ago I have a chat conversation with one russian guy (Mo3ulla) and he has 256 RAM on the Uni (bga chips from notebook) and running Windows CE (custom port, never comes to public), so it seems it's possible, but not for public

A light!!
Well,
If that is actually true there is hope that can be done!!
Hope someone can publish this soon!
I´ll ask mo3ulla
Thanks for the tip,

Interesting reading this thread - especially this post
I don't know if the guys are still around - it was only 18 months ago.

Well i would think someone will get the way around to get it done .....

May be you are right.
But if something is not published publicly then it may not be fully true....just my thought.

Mamaich did the original work on patching the Kernel to allow access to the 128mb ram, if bigger chips are available for the two slots then there is no reason why the memory can't be further upgraded, it would however require another kernel update to allow access to the extra memory.
The same goes for the GPS slot, if someone was willing to install the GPS chip and patch the radio stack, there's no reason why the Uni couldn't have a GPS chip.
The only problem you have is that the Uni has been around for far too long now and all the Guru's have moved on to other devices.
Try convincing someone to spend months patching an old device to have the features already available in newer devices............ you would be better inserting a new mainboard into the Uni chasis........

Thanks for your clarification Beasty!
Well, I would love to convince a master to do this hard task, just want to know who can be a candidate.
And on the other hand we should rise a nice donation so we can encourage him!
I offer myself to rise the money to convince him/her
So any recomendation is welcome!
Later I´ll set up a new thread for the donation in case this makes any positive progress.
Cheers,

I'd certainly donate towards anyone getting GPS inside my Uni if it helped. However, I think as Beasty says, I don't think it's going to be money, but someones time.

Time is not a problem as long as somebody really want to go deep in it
I can wait the longest as it takes and I´ll be just a happy pacient Uni user!
$ can incentivate
Let´s how all this move forwards...

You will be hard pushed to find a candidate willing to take on this task for you.
There are not many developers here who are capable of both the hardware and software modifications required.
Don't get me wrong, there are some very good devs in these forums, but this sort of mod requires a lot of low level hardware and software knowledge.
Your best chance if you really are serious about trying to find someone to do this is head over to Darkforces and make a post there.
Really you would need Mamaich, Ivan or Helmi (to mention a few.....if you can track them down) as they are all more than capable of what you want.
To be honest though, you probably have more chance of getting HTC to do it for you..............
It would still be easier to port a new mainboard into the Uni housing (more than enough room in there for most of the current devices on the market to fit............... perhaps you should also consider this as it is a more practical move than trying to upgrade a dying device.
I love my Uni as much as the rest of you guys here, but there comes a point when you just have to move on.
Over the years we have patched the hell out of the kernel and drivers for the Uni and to be honest the code is quite a mess now, far from optimised.
Good luck and keep this thread updated with any news you have on progressing this issue as I would be very interested if you found someone willing to take on this challenge.
I know first hand how messy all the drivers and patched oem files and XIP are in the Uni and it will be a monumentous task.
Cheers,
Beasty

Beasty is right, as we all know, but if we take in account what was written in Orb's thread about Uni vs new devices there are a lot of us that are not satisfied with the performance/cost of the latest, me included.
How can it be possible to release a device and i can't even play avi with it?
Runing the same apps on both devices, I can't notice a real improvement in terms of speed. memory we know that's short...
My HD is nice, but as I told, I would prefer the Uni with 256, even being a lot bigger.
Unfortunately we (Uni) suffer from oldness, and we will have to move on...

I agree the current Qualcomm chipsets are not up to par, mainly down to driver issues rather than the hardware. Don't forget our Uni's run off an Intel XScale and not a Qualcomm.
1st quarter of next year should see some decent releases of the new hardware Tegra and Snapdragon with 12mp cams, 1 ghz cpus and video recording at 720p, perhaps then the Uni will finally have a decent replacement.
I must say though that my Rhodium is no slug, the keyboard is nice and big more than enough ram (GPS is functional, though not great it does the job satisfactorily) I can't really say I miss the Uni that much after switching over to the Rhodium................ each to their own.
Hold out till next year and be tempted with the new hardware.
Cheers,
Beasty

Does the Qualcomm have a serial or USB port (USB host)? I have no idea but I know that much older chips did have (Intel StrongArm in HP Jornada for example - but was not used and also PXA250 have it). If yes and if it can be found somewhere on the PCB of the UNI, then this can be used for GPS connection, or something else. Just an idea....

Both the Qualcomm and XScale can support USB host, they just require the correct drivers, the functions are available just need to be accessed via a driver. The problem the Uni has is that it has no built in GPS Chip, there is a placeholder on the mobo for a GPS chip, it was just never added. There were rumours that some of the very early Uni's (G3) had a chip but not activated.......... Personally I have never seen proof of this.
You can still use external GPS on Uni (as many do) via BT or USB/Serial connection. You do not need USB Host service for this function.

windows mobile devs could OC same CPU as magic's CPU to 800Mghz

hey guys,
I saw winmo devs OCing this same Magic's CPU up to 800Mhz with great performance boost.
any one could reach same with android OS so far?
URL: http://wmpoweruser.com/?p=7461
thnx!

first off, the touch pro 2 isn't a magic. at all.
second of all, this is completely wrong forum. please read rules.
third, it probably never will happen. someone did it a while back and there was a huge debate about whether it worked or not and it was finally confirmed that it didn't work.

I can't find the word magic anywhere in there!!! Damnitt!!
so it leads to this question,
How did you come to the assumption that you could OC the magic when nothing about the magic is there?

The cpu is the same on the magic...

It's a shame that project died. I really believe that it's possible if the right person would try cause it already worked on a lot of phones. I used to clock my Omnia at 800Mhz which gave it a great boost and there was no real battery drain. They've also managed to clock the N900 cpu at 1Ghz:

No, it wouldn't. You're buying into the megahertz myth. The magic has a ARM11 (ARMv6) chip, whereas the N1 has a Cortex (ARMv7). It's more like a P3 against a P4 - the clockspeeds may match, but the performance is still going to be off. Not to mentium ARMv7 has a bunch of new instructions (NEON), that are not present on the v6. And the GPU still wouldn't support OpenGL ES 2.0. It may speed things up sure, but it wouldn't really matter.

sadly it's not the cpu preventing me from overclocking it! it's the software in the phone, the pll's are defined in the spl and it would take i SIGNIFICANT skill of hexing and backporting to do something about them! and by the way it would almost certainly brick the phone! i'm sorry guys the only thing i ever was able to play a litlle with was some parameters giving a little better gpu performance, but it's unstable

Apad M70003 MIDI

Hi all. Just finished ordering this tablet that is currently running cupcake. Would love to root it and install a custom ROM. Any info on how I can achieve this?
Thanks in advance

offtopic... does the apad run any good? is it smooth?

Why is it off topic. It is a tablet that runs android. Do not have it yet so can't comment on how good or bad it runs.

i was asking an off topic question (i.e. not related to your question). guess i phrased my sentence wrongly. do post here on how well this device seems to perform.

I will. Thanks for your intrest.

You should of waited for the Notion's ADAM

I only paid $100.00 US for my tablet. This one is considerably more.

hey could you pm me the site where you purchased it from?

could you update your main post with the specs that you ordered from? Apparently there are Apad clones with crappy processors instead of the rockchip processors

Dealextreme has it for cheap

dealextreme is the crap version. the proper apad is the one with rockchip in it. and i found out that the cheapest apad with rockchip is ~150usd

i have one of those too.
with the rockchip which actually is not to bad of a processor. nowhere near the A4 but ok to work with.
it's an ARM derivative and consists of a cpu and dsp(gpu).
i would also like to know if anybody has played with it yet.
i followed the android instructions of building a development envirnment and have the tablet actually show up in eclipse but where to go from here?
sorry for threadjacking a bit
i would first of all like to be able to upgrade android. if possible 2.2 or at least to 1.6.
the device has the upgrade locked.
the are also language option conflicts were suggestive text and some keyboard keys still show up in (i guess) Chinese.

It'll most likely be impossible to upgrade the apad to 2.1/2.2 as rockchip dsp isn't actually a gpu, its a video processor for videos only.
on another note i have decided to pass up on the apad as it doesn't seem that "future-proof" most likely will get this http://www.wiipad.us/product.php?id_product=11 unless better options come out in the next 1 month or so

does android 2.x require a specialized dedicated gpu?
the dsp is essentially a gpu, it is capable of playing 720p video.
it should be plenty for android 2.x to get around
so i can move files from the device to the pc.
i copied the data and system folder.
what to do now?

Yeah but it decodes videos only, a gpu actually pumps out the graphics which is an intergral part of 2.1 onwards (also in the rockchip's specs i saw somewhere this chip does not support 2.1) The wiipad neno has a cortex a8 core which is similar to the ipad's processor so it is running on 2.1.

[PROJ] Overclocking the Adreno GPU on Snapdragon Devices

I already posted this in the Nexus dev forum, and I hate to clutter the boards, but I know that there are a bunch of talented devs here that may not see it on those forums. If we can bust the 30fps cap for good, and get the GPU overclocked, then we could see some serious gaming performance out of our Snapdragon devices.
I'm sure we all heard about being able to overclock the GPU on some of the old MSM devices, but the Snapdragon handles the graphics chip in a different way. The goal of this thread is to try and overclock the GPU on Snapdragon devices as well.
There is nothing GPU related in acpuclock-scorpion.c (the Snapdragon cpu clock settings) at least for setting gpu clock speed as far as I can tell.
In board-mahimahi.c (Nexus board file) and board-supersonic.c (Evo board file) there is some kgsl init code, but so far as I can tell it isn't setting the clock there, instead it seems to be pointing to PWR_RAIL_GRP_CLK to set the clock in both devices. It defines the variable in each of those files but I'm not sure where that variable is set, since it doesn't seem to be in any of the other board files as far as I can tell. I could be completely off here too though.
In drivers/video/msm/gpu/kgsl/kgsl.c there is a method called kgsl_clk_enable that seems to be called whenever the GPU is enabled. It looks like this:
Code:
/* the hw and clk enable/disable funcs must be either called from softirq or
* with mutex held */
static void kgsl_clk_enable(void)
{
//clk_set_rate(kgsl_driver.ebi1_clk, 128000000);
clk_set_rate(kgsl_driver.ebi1_clk, 245000000); // Looks like it sets the GPU clock, right? Wrong.
clk_enable(kgsl_driver.imem_clk); // Enable the clock
clk_enable(kgsl_driver.grp_clk); // Enable another clock, but why?
}
The line that's been commented out is the original value, I replaced it with my value on the line below it in a failed attempt to overclock it. Probably a stupid effort on my part, I doubt it's that simple, but it was worth a shot. The comments at the end of the line are also my additions.
According to the clk.h files in the standard linux kernel, clk_set_rate is obviously a method to set the clock rate. The first variable is a struct that tells it which clock to set, and the second variable is a long value that is the rate you want it set at. Is it setting the right clock there for Snapdragon chips? Or is it only the clock for older chips?
I'm in way over my head with this source, I'm but a lowly Java dev, but I really wanna solve this. Can anyone with a little more experience than me throw in a little more info? Sorry if it doesn't make much sense, if it isn't clear just ask me & I'll try to explain a little more.
Regards,
Jesse C.
EDIT: Okay I did a little more digging and those kgsl settings should work for QSD8x50 chips. In the config file, under Drivers, Graphics Support, it allows you to enable 3D accelleration for QSD8x50 & MSM7x27 chips. The tag for that is CONFIG_MSM_KGSL_MMU. If you check in kgsl.c it checks to see if that is enabled in the config, and if it is then it compiles and uses kgsl.c & all of the kgsl code. That tells me that the clock is either not being set, or the wrong clock is being set. I'm adding some debug code right now so I can see in dmesg what code is actually being run.

Dude I have no idea how to do this but bump and best of luck

Yeah I saw that, but that won't work for us, because it is for one of the old MSM7500 chips instead of the new QSD chips we have in Snapdragon devices.

i wish you guys the best of luck..wish i could help..i love xda..lol

I'm going to bump this, would be nice if more people were working on this.

Man... I absolutely love my phone. It really sux that this even needs to be asked. This device is so much more capable and I cannot understand why HTC would cripple it so badly. Look at the Samsung galaxy s or the Droid x. Or even a more similar phone like the nexus or incredible. They all stomp this phone when it comes to anything graphics wise even if it is just swiping home screens. It makes me sad. Lol

I love how it makes you sad, but you still lol. Lol (correctly placed)

I don't know, yet I am in deep havoc lol. I activated my phone on the 20th. I have till 13th of July to pay my bill, so don't know.
I mean the locked bootloader of the Droid X is kind of lame. Also on the Evo, I have a 10$ discount because of the IO conference... unlimited texts too, and I bought two batteries for it with a charger(for 10$ lol, and they actually last a long time 1500ma, I put the 2 extras in my wallet)
Also I think I can upgrade my phone right away already if I read things right, so if Sprint gets an awesome phone I can upgrade to that whenever.
Verizon is more expensive, but I like how they let me do a 1 year contract. The Droid X is also nicer, I mean it has a better camera, and the mic quality when taking videos isn't piss, hopefully someone fixes that. It also has a real graphics card.
So yeah, it's hard to decide. A better phone, vs saving me some money. Though I plan to attend the IO conference once again. I'm still porting my distrubuted prime client onto Android, hopefully it will be high performance. So it's not like I just go there for a phone ^^. Hell I didn't even know about the phones till they said "Where do you want the Droid delivered" I lol'd. Though my time is limited, summer classes at UC Berkeley are tough : /

Also what's the point of overclocking if their is still a limit on FPS..

There isn't really a fps cap with the novatek kernel hack. It made the display much smoother for me and I am using it on EvolutionX. So beast.
Good news about the drivers, maybe we can actually see some overclocking now.

I want this to happen!
Nova runs pretty well on the Evo. Gameloft updated it recently.
I would just like for iphone ports to run well.
I hear the Palm Pixi has the same GPU. It is clocked at 190mhz. What about the Evo?

The Pixi doesn't have the same GPU, it has one of the low/mid-range MSM7227 (I think thats the model?) chips. It's similar as it's one of Qualcomms latest gen chips, but it is NOT a Snapdragon so it's different.
Also, the Snapdragon GPU's on HTC devices are clocked as follows:
GRP_CLK: The actual graphics clock, 256mhz
IMEM_CLK: The gpu memory clock, 256mhz
EBI1_CLK: As best I can tell, the bus that the GPU is on is EBI1, this is the clock for it, 128mhz
If you want more info, look here: http://forum.xda-developers.com/showthread.php?t=710850 since that thread is a lot more active, but please don't clutter it, there's actual devving going on there

Thanks for the info. I just wonder how they're going to get 3d games to work on the Pixi then... weird.
It was announced that the Pixi would get 3d gaming with the 1.4.5 update.

Much better (Y)

Can i upgrade RAM

Hi friends, i am new member of this forum, i have recently bought Karbonn A21, facing problems coz of low ram.
Can anyone help me, i want to upgrade my phones RAM first of all is it possible if so then how.

mobile devices aren't like pc's - you cannot solder in more ram into the soc .
however you could use swap similar to virtual memory in windows where in a portion of your sdcard will house a swap file onto to which some stuff will be off loaded when running out of memory

You can't upgrade RAM as it's already prebuilt in, the best bet is to update to the latest firmware which includes improvements and close apps that isn't being used

Not quite sure what these other people have been drinking, but a RAM chip is soldered onto the main board of current phones. This is not simply 'upgradeable', nor will any manufacturer notify you or even offer a RAM upgrade for your phone.
If it is possible, then you will need a ram chip for a phone that runs on the same voltage and amps, heat the soldering around your current chip on the main board (which can cause immense damage to the phone and give you a nice, shiny brick), pry it off, replace with new RAM chip, reheat it into place. Then hoping the phone accepts it and doesn't just lie there, making smoke and sparks.

No you can't. Just real PC, no phones or tabs.

Yup. On SOME phones with VERY good soldering skills you might be able to replace the RAM chip.
However based on how the OP asked the question, I don't think they have the skills to replace the RAM chip without destroying their device.
Also, many devices now use PoP (Package-on-Package) RAM where the RAM chip is actually ON TOP OF the CPU chip - it is nearly impossible to rework PoP RAM without destroying the device. Heck, it's tough enough to even manufacture - I believe BeagleBoard was delayed quite a bit due to PoP manufacturing issues.

For now only can reduce the ram usage

Hey man your best bet is custom rom as in it we can remove useless apps and make more memory free but you lose your warranty but hacking your phone in best part as god forbid something goes wrong you can take your phone to customer care centre and say i don't know what happened and they will fix your phone. So any time you want custom rom message me I'll help you out

i don't think you can. just use a custom ROM that optimizes the ram you have

It will surely be easily possible in the future, but I think only on Android.
Or at least, Open Source Systems .

It is not related with the operating system of the phone but it is related with the hardware design of the phone.(open source is not related with this at all)
Some people mentioned that you can replace ram and the possibility to work is really low. It is true and also because our phones work in high frequency the electromagnetic effects should be considered too.

Honestly the thread title made me lol. You can try to increase cache size but no RAM upgrades possible.

That is not entirely true. Open source is a term that applies to open and available documentation and resources that shows you the internals of either software or hardware. Open Source means that the originator/creator of what you are looking at is generous enough to share the "blue prints" on how to make said item. As such, hardware can also be open source.
