8 mb RAM chip for me??

[madmodder]

Hello all

I want to change my ram chip for the 8mb unit as I have a 100gb hdd in my "rockbox" (actually the archos jukebox recorder 10) and the hdd takes 900ma  
I have some old laptop memory, it seems to have the right memory config but the chips are 54pin tsop
The original mod done online looks messy enogh as it is..
So can anyone help me out?

Thanks all

Ok panic over.
I've managed to source a chip so that's my request solved by myself  
(the system will not let me self-terminate LOL ) - I mean delete

Where did you get the chip from?

I have been trying to find one for months now!

[madmodder]

Yes! Ram Chips are available through this guy!
Bruce Benson "bruce - at - sparkybruce - dot com"

If you count the two chips I have dibs on - then he's got 79 chips available
The cost is £5 per chip (that's pounds sterling) PLUS a small fee for postage.
My quote was more that reasonble but I guess the postage will depend on where you live!

Now I have an archos recorder that I am modding myself and I'm prepared to put a guide up on this site

Hello all , yes  I do have a supply of the chips , though after counting them i the tray I will have 68 left after I send two to madmodder.

They are made by ISSI and I have the full data sheet availiable though it's 160Kbytes so I can't attach it on here.

I will put it on my website and post a link from here tomorrow.

I modified my 6G recorder over three years ago and it hasn't missed a beat.

I have sent out a number of chips to people all over the world but interest had appeared to have stopped just over a year ago. So the chips have been sat in their packing tray all wrapped up with all of the other chips that I keep.

Now if only I could find some one that wanted 16Mbyte EDO laptop SODIMMS (72pin) as I have over 400 brand new ones)......

Thanks to everyone for the interest , and please feel free to ask me any questions to the modification. I can even take my one to bits again to take some detailed pictures if that would help.

I considered doing an upgrade service , but at a few hours a time it probably wouldn't be worth it.

I do have a number of diferent memory chips from smaller EDO's right up to 128Mbit PC133 SDRAM's, and I am currently building a number crunching farm (for boinc and seti) out of scrap Set top boxes from work.

1000 boxes each with a 350mips PowerPC with 128Mbytes Ram , 16Mbytes Nand , 10/100 ethernet, running linux and the best bit consuming just under 2watts of power. All in a pcb that's 75 by 75mm.

Thanks

Bruce

For anyone looking at this, and are wondering where an existing tutorial might be found, will find this link handy: http://www.uwe-freese.de/hardware-projekte/rockbox/8mb_ram_en.html

Thanks!  I have been looking for these chips for quite a while.

I considered doing an upgrade service , but at a few hours a time it probably wouldn't be worth it.

Maybe not, but there are a few people who have approached me about doing this upgrade on their devices, and I was planning on doing it for them (except I could not source the chips).

Hi , I forgot to upload the datasheet to my website , but if you want a copy send me an email and I will send it off to you.

Thanks
