hi @all one found out that the streamdump shows in the systeminformatio 512mb ram but only 700 mhz....so this cant be the stream specs couase it runs on 1ghz... so the liquid must have 512 mb which is restricted to the half?! am i right?

some times these specs are hard coded to the rom

If you look at the BogoMIPs of the CPU, atleast on 1.6 roms, it always stays at about 500, no matter what you set the clock speed at.

tried to set the clockspeed to500.... specs stay the same.

so i think they show the max values

Some people are saying that our Liquid can have 512Mb.. 256Mb are shown & 256Mb are hidden..

How can we find out?

If Liquid A1 would have 512 MB of RAM, like LiquidE, we would be able to access it without making any changes, since we flash LiquidE bin, so everything (when it comes to software) should be same.

One guy, who bought LiquidE in Rogers flashed 1.100.05 bin, and made a mod for it (look at xda for details)

What is the most interesting, is that he has ~300 mb of free RAM shown in task mgr widget

Liquid A1 owners get ~90 mb of free ram with 1.100.05

In my opinion, if Liquid A1 would have 512 MB of free RAM, we would be able to access it when using LiquidE ROM. But we get only 256 MB, so I think that Acer simply kept same motherboard for LiquidE, but changed the RAM chip.

We would need two volunteers to disassemble Liquid and LiquidE to prove it.

On Liquid (and most android devices actually), the available memory is declared by the bootloader, not the boot.img, so they can still somehow hide it.

Anyway I'm pretty sure there is only 256+32MB of memory in our devices. I'll test it though, just in case. (Just needs to search the EBI2 address in other qualcomm devices' sources, and see if we trigger exceptions when read/write to it)

OMG ;)

Yes I followed extreme22 thread.. on xda

I'm not ready to dismantle my liquid... I have to dismantle soon.. but i think i'll go to a service center...

And volunteers? ;p

Well the Tmobile G1 has about 500Mips at 528MHz, 350 ish at 384MHz, I think Acer is just to lazy to implement a Mips calculator/measurer

Il disassemble mine in the next few days maybe tomorrow, cause i need to grab the T5 screwdrivers from my brother.

Hey guys, I just known that our friend from China had his A1 disassembled and he also uploaded the pics of A1.

However, the quality of the pics are awful..cant really tell the words on the first chip of the top, I can only recognize few words like Samsung from the top of the first chip.

Perhaps someone could has this pic processed by Photoshop?

I have been trying to ask him for the better pics of the RAM. I'll upload it once I got it.

Here's one from the topic:

I can confirm that I have on average 200-300mb free using my acer liquid - and this is the same regardless of rom

i used LCR 1.6 with the same results , and my modified rom will hold the same

The liquid E from rogers and other providers will have 512mb ram

the original liquid has 256 - this is the same as has been done with HTC and the 32b/32a chipset

identical phone except small changes and 100mb more memory on the 32a chipset

this is more compatible though as there is no change other than the ram and the kernel already supports both it seems where with 32a/32b seperate kernels are req

no point in disassembling your phone to confirm what we already know

your not getting any extra memory - trust me ;)

I wont count on it... Its simply like the Iphone 3g & 3gs.. (Same chips different frequencies)

They are not changing the product line process if they can do it easily via software...

Its just hidden there, we just need a dev to find it...

your just making up excuses to give yourself false hope

as stated I have full access to the 512mb ram as it is based on the hardware

people with the original liquid only have 256mb...

the iphone 3g and 3gs are not the same chips at different frequencies either..

ARM 11 412 MHz, PowerVR MBX-Lite graphics - Iphone 3g

ARM Cortex A8 600 MHz, PowerVR SGX535 graphics - Iphone 3gs

please have an understanding of what is going on here instead of just making up stuff to make yourself feel like your gonna get more ram and it will never happen my friend

they had to start a new production line for this phone as the radio inside the phone is DIFFERENT for north america freq as well

so what makes it so far fetched they added a 512mb chip instead of 256, or even that with eclair they decided to switch to 512mb to ensure that the phone can handle future upgrades easier????????? nothing at all

Here's a picture from the FCC

s100%20board%20pic.png

The 9JA98 JW258 chip should be the ram chip, but im not sure, and judging by the "258" im pretty sure it is.

Thanks for that. Wish it were more but oh well.

Any datasheet about this chip? And who is the Manufacturer?

I have never saw that logo... M

There's no point in hiding RAM. They might as well tell truthfully how much it as as it gives Acer a better selling point. The only reason why the older A1 came with 256 MB is because it's cheaper, and now 512 MB chips are probably the same price as 256 MB half a year ago, and therefore why it's in the E.

ermm actually is one of the most popular ram manufacturer.

M aka micron ;)

i'm finding some information and the model micron sw258 is the micron MT29C4G48MAPLCJA-6 IT

some information

the documentation http://cache.micron.com/Protected/expireti..._sdram_t48m.pdf

it is said documents and official website micron, the chip has 1GB ram ;) . I do not understand

Hopefully somebody figures out how to up our ram to 1GB.

NOW THAT WOULD BE BEASTLY.

Raffyvito,

Would it be possible for you to get a picture of a stripped down Liquid E so we can compare the 2?

Thanks in advance.

Yep we need a dismantled one ;p

Does anybody have instructions on dismantling the Liquid... I need to replace the LCD but I can't get the damn thing opened. Any help will be appreciated..

1gb or 256mb it wont make a difference, you wont get better performance just on density alone (Ram frequency is a different story)

This isnt windows, linux runs the same regardless of free memory.
