Old motherboard identification


S

snydley

I've resurrected an old Pentium computer from the early '90s, an old system
of mine that's been in the closet for a few years. I got it up and running
well, but it only has 64M of RAM in it and I would like to add more, if it's
even available any more. I'm trying to identify the motherboard so I can try
to figure out what type of memory it takes.
So far, I remember it's an Intel motherboard, with AMI BIOS # 1.00.06.CB0,
(from it's startup screen). I tried the AMI's motherboard utility but it
didn't work, I presume because it's so old it couldn't identify it.
Can anyone help me identify this MB or tell me what kind of memory it takes,
or a website that might help?

Thanks,
Snyde

since you need to open the case to add more memory...
you might as well just open it now and have a look at the memory that's in
there now.

BTW: if you are using win95 on the machine, the 64 megs of memory is more
than you need anyway...
and for win98 should be ok...but another 64megs would not hurt

With a dinosaur that old, the best approach is to check
the existing ram and get some more of the same type.

And yes, they are still readily available on ebay.

I would be surprised if it was anything other than 72pin EDO SIMMs.. being
early 90's I would doubt SDRAM.. (that's more toward the late 90's and PII)

Open up the case and take a look.. that will show you what memory is
already there (so you can buy more)..

Chris

Better odds for 72pin FPM simms. EDO was relatively rare. And it's
really hard to tell them apart without either good labeling (RARE), a
memory tester, or getting lucky with google.

You've got that backwards.

It isnt hard to check the numbers on the ics themselves.

I actually do have an honest to god simm tester that tells me the
difference between edo and fpm simms. I've literally run tens of
thousands of simms through it. At most, 1 in 10 simms tested is edo.
Even the 32mbs are skewed heavily to fpm.

30pin simms are almost exclusively fpm.

NEW simms are most often edo. But not vintage.

Its hit and miss. Really. I've been there. Often if you do find a hit,
it's some obscure parts reseller, who only lists a part number, and
little else.

That's the problem, its getting it wrong.

Have fun explaining the ratio seen on ebay.

Wrong again.

Nope.

There's a couple of decent listings of ram chip specs of ram chips of that vintage.
Cant find them on the web anymore, I saved them when they were still around.

It's always been consistatant with labeling, when i actually see
labeling.

That's an easy one. EDO is better, the fpms are worthless. Except for
materials recovery.

Nobody really wants 8mb 72 pins, if they want an upgrade, they'll go
with the 32s and pull the existing ones. Our daily supply of those is
greater than the entire ebay listing of edo AND fpm simms. We currently
have to scrap the bulk of those, rather than attempt to resell. You
want to buy a 4 cu ft box of obsolete ram, rom and cache? It's actually
worth quite a lot of money as scrap.

What matters is whether what it claims agrees with the ic part numbers.

Oh bullshit. You wouldnt normally be able to pick it in a double blind trial.

Irrelevant to that silly claim you made.
