380z with 160mb ram

[blitzdings]

hi ,

i have an old 380Z 2635-Jxx with 300 mhz cpu, 98mb ram (32/64) with bios 1.07
Now i am going to try a ram with 128 mb instead of the original 64mb for upgrate to 160mb - edo 144pin 60ns... exactly the same spec.

My problem is, the bios found the ram with no errors but only exactly 97.728 KB on ALL rams i tryed. I have two rams with 128mb.

Is my new ram only a 64 mb or is there any limitation at the bios or the chip?

Thanks for help

if it really is a 380z, you should have a p2 with 440bx chipset.

so, your ram should be sdram and not edo.

i assume, you just didn't type right.

have you tried resetting the bios once you've changed the amount of memory ?



(btw: blitzdings klingt deutsch... wir könnten auch so, aber dann verstehts hier wieder keiner...)

Thanks for response and thanks for looking.


The CMOS reset was a good think. I had try it but after that the same result.

I'm shure the TP is a 380z with following specs, tested with AIDA:

CPU Typ Mobile Intel Pentium II, 300 MHz (4.5 x 67)
Motherboard Name IBM 2635JB0
Motherboard Chipsatz Intel 82440BX/ZX
Arbeitsspeicher 96 MB (EDO)
BIOS Typ IBM (09/04/99)
Anschlüsse (COM und LPT) Communications Port (COM1)
Anschlüsse (COM und LPT) Printer Port (LPT1)

Motherboard Chipsatz Intel 82440BX/ZX
In-Order Queue Depth 4

Speichersteckplätze:
DRAM Steckplatz #1 16 MB (EDO)
DRAM Steckplatz #2 16 MB (EDO)

DRAM Steckplatz #3 32 MB (EDO)
DRAM Steckplatz #4 32 MB (EDO)

On IBM's website, they also give the ram as edo sodimm 144 60ns ...

Maybe the ram's I had by are a fake - they have only 64mb. But why all ram's, also the original IBM,
are spec in the cmos with exactly 97.728 KB.

Have anybody an idear?

Thanks

BTW: Yes, you'r right - Germay/NRW
The Thinkpad is using by a little girl in a network at home.
It's only for i-net and office use (XP-Pro, office 2003, icq ..and so on).
Remoutly it conect a subnet-PC for greater jobs. So she can use the TP to display the pc.

very strange...

afaik, the 380s with p1 and 430tx only had edo, the p2 should have sdr...

anyway, if its edo, you sure do have 128 mb? if so, the dimm must have 16 chips.

for example: 128mb edo @ ebay.co.uk


the problem is: does it fit with the height of 44mm?


if not, 96 mb (32+64) is the max.


btw: i myself own a 560x (sig) and a 380xd, so, if you need some tips about configuring the os or appropriate software for these oldies, feel free to mail...

Thanks for the link.

My new ram is a standard 128mb EDO 144-pin SODIMM by Aved - was into a Compaq.
Part number AVED16F664LSD8TS-60. Each piece is 16Mx64=128mb, EDO, 60ns, non-ECC, 4k refresh.

This is a low-profile module only 1"/25mm tall. An 128mb EDO RAM module must have at least 16 chips,
which makes many such SODIMMs to be inconveniently tall. This model is based on the stacked-chip design,
meaning each chip is in fact 2 chips stacked on top of each other, but with 2 separate sets of pin connection.

Can it be, that the stacked-chip design is not supported by the controller. Only one layer by site is
right for work. So can be explained that the cmos shows only 64+32mb instead of 160 mb (32+128) totally.

Can it be? The 380z (ore all Thinkpads?) will not be able to fit a double stacked memory?

Thanks

nope.

seems to be a limitation by the bios.

it doesn't matter the controller if the chips are soldered one by one in a row, in circles or one over the other...


still, it seems very strange to me that a p2 has to cope with old edo-ram...


how much did you pay, or better, would you eventually sell me the 128mb brick?

i would like to test it in my 560x. since its a p1...

[blitzdings]

O.K. Thanks for looking and special thanks to gbm31 for the replies.

I'm sorry for my late answer.


In meantime I was looking the web for any reason to try an other ram.

Here my results:

1. gbm31, you'r right to say that the P2 supported sdram, but in the 380z is bassicly a edo with 32mb and you can't
run an edo with a sdram on the same board.

2. So take a look at these link. It shows a 380z with 160 mb of ram (32+128) - please scroll down.

http://cgi.benl.ebay.be/IBM-ThinkPad-38 ... dZViewItem


Also there are many special offers about 128mb edo sodimm for the 380z - e.g. like these link

http://cgi.ebay.de/ws/eBayISAPI.dll?Vie ... %3AIT&rd=1

Meant that the 380z has no limitation to use a 128 mb stick.

3. The 380z doesn't fit a modul with a height of 44mm. The available space insite is 38mm,
so you can use only a narrowly module.

Maybe I find a cheaply modul - sometimes.

Thanks

Hello:
I am having the same problem with putting a 128MB chip into the
380Z and it only recognizes 64MB. Did you ever have any luck in
overcoming this problem? I am still trying. I updated the BIOS but
that didn't help.
Thanks,
Mark

the 380z thinkpads do indeed use edo memory, ibm never offered
a 128 meg upgrade, but kingston as well as several other vendors did. these memory sticks were specific to the 380z (the kingston
even had 380z in the part number) and very expensive. expect to pay $50+ for one. you must make shure that the memory you are purchasing was indeed for a 380z. you might have also gotton a stick that was mis-labled. you MUST have that 128
megs to run xp. you must also upgrade to the latest bios to allow hard drives larger than 8 gigs to be supported, and the sound to be supported in xp. good luck, adrian

1. gbm31, you'r right to say that the P2 supported sdram, but in the 380z is bassicly a edo with 32mb and you can't run an edo with a sdram on the same board.

Just an FYI, even if the onboard EDO memory is disabled, the 380z still won't handle SDRAM. It didn't work when I tried it.

Also, looking at my machine, it seems possible with a little bit of cutting you might be able to fit a stacked chip in there...

To settle the argument of EDO vs SDRAM the 380Z only accepts according to the twbook -

"Processor Intel Mobile Pentium II 233 or 300MHz / 66MHz system bus.

Memory - std / max / 96MB or 160MB* / non-parity / 3.3 volt / EDO / 60ns

Memory - features 1 socket for one JEDEC 144 pin EDO SO DIMM of 16, 32, or 64MB

* Maximum memory capacity with 128MB SO DIMM from ThinkPad Proven vendor."
