Upgrade 6700 to 128M RAM, attached benchmark report
 

Hi, Guys,

Two days ago, I published 2 photos for the 128M RAM upgrading. Now, we published the details as free already. Please check the below link in Chinese.

Hardware:
You could find the memory chip model in the below link. There are some photos which destrib the modify solution, it is easy to understand.

Software:
http://www.diypda.com/viewthread.php?tid=8137&page=1

I simply translated it as below:
1) Memory Management in XV6700 (Look at the below character)
2)SDRAM Analysis
3)Connection between CPU with SDRAM
4)Bootloader
5)Bootloader Modify

I attached the bench mark report for 128M RAM 6700.

You could read it via internet translating system and I will publish the English version by this Friday.

Also, there is an WM6.1 XIP for XV6700 download, please refer the below link which is done by Jockey:

wow....the 67 will not die.....but I am pretty sure it required some serious surgery for the memory upgrade.

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Damn you...give it to my Mogul!

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Whoops sorry, did see you said "we", how much are you charging for the mods?

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

So how is it done?

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Does anyone know if the 6700 and the 6800 are close enough in design that this could be a glimmer of hope for the Mogul?

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

well..... thats nice.... no more info on it. just pics no info... thus far its like waiting for bad sex.

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Aha...
Yes, it is "we", not just "I". This job was done by my team. We are testing the upgraded one, so far it is good! But there are still somethings unsolved.
Once we finished the test, we will share the upgraded solution with you.
In order to find the upgraded solution, we lost 3pcs of XV6700, :(! But we are still glad to see it was final sucessful!

For the 6800, I think there are already many peoples are studying it to upgrade the RAM. I saw many threads talking about it. I only can say the design of Mogul is different with Apache, it is more difficult than Apache. But we are trying to do it. Because the Mogul is more expensive than Apache and there are few failed broads can be bought, our progress is slowly...

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

ahhh yes, what would this world be like if we could no longer buy failed broads on the side of the road?:evil4:

only kidding, his typo surely meant boards ie devices....

sorry i just couldnt resist.

nice work Arlen, make it happen for the mogul friend!!

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

I Hope There's One For Our Moguls, But This Was Done In China. Nice Work Man.

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

So the big ? is what kind of performance change(s) are you seeing? can you post some benchmark screen shots or something?

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Very nice looks like I will be going back to my 6700 and retiring my 6800 after this is released.

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

SMH... you're serious arent you?!:angry7:

It would be ironic with that signature..

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

I want to know the same thing, what kind of performance increase are you seeing? I know WM6 is running fairly slow/sluggish on my ppc6700.

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

I would love to see instructions for tis heck with 128 mb it puts it on par with a lot of current ppcs...
so I want to see

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

this is pretty sweet. guarantee i could do the physical work, long as someone showed me where to put the chips.

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

just show the un-verified fix already! My salivation has produced a bath, a pool and this lake I'm swimming in with my king size blowup bed floating into oblivion sipping on some beer with my ppc texting this message to you right now...

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Can we get Moguls/HTC Titans sent to China? Come on now, this is not outside the realm of possibility now.

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

You're trying to work with Moguls on doubling the RAM? Post here as well: http://forum.xda-developers.com/show...2&goto=newpost

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

This goes back a long way, but I seem to remember that soldering the chip in place was only the first challange. Getting the device to fully recognize and USE that ram was the sticking point. This may be why we aren't seeing any benchmark tests.

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Sorry, in China, the Mogul is more expensive than in USA. I am also looking for the broken boards in ebay.

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

*Bows down before your great Chinese prowess*

Please try very hard for the Mogul as well

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

i'm really curious as to whats required to make use of the mod software wise.
either way. good luck.

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

I couldnt download any of those wm6.1 roms on that site :/

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

On the mogul,there is no mystery what needs to be done. You need to get a chip with twice the memory. The problem is,there is no chip listed in the Samsung catalog with the proper specifications. The ram is contained in a mcp (multi-chip package) along with the flash rom.

This does not mean that such a chip does not exist,in fact it is suspected that the vogue uses just such a beast.Samsung will in fact make any combination you want. (if you are willing to buy 100 thousand or so) What we are missing is a good high res image of the vogue so we can verify this and get the number off the chip. Once we know what chip it is,and can find a source of them,then its just a matter of putting it in. (assuming that the board of the mogul is wired for the larger chip,which is not certain) This requires a degree of skill,and some equipment that may not be part of the typical hobbyists gear.(it is however readily available)

There is however one additional issue. Since the rom is contained in the package as well,and must be replaced at the same time,the chip will need to be programmed. This can either be done prior to installation or it may be possible to do so after installation if a jtag port can be found in the phone. Its probably best to do it before hand however. This will require an appropriate programmer to be procured or built.

As you can see,the issues are known,and potentially solvable,but random poking about,swapping chips and bricking perfectly good phones will not do the trick.

Bump............

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Stupid question but where do we purchase the upgrade for the Apache?

Thanks,
Steve

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Arlen: any more news re: this? Did you get the updated ram to run stabily?

And more importantly to me, did you get anywhere with the 6800 / mogul / titan, yet?

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

arlen can you upgrade on this i think it is interesting and i saw that you still log on is there any new info how is the phone still holding up

Re: Good News! Sucess to upgrade 6700 to 128M RAM!
 

Seriously, I am wondering if this is a hoax. The guy only posted a few times too...
