Old Presario 1255, new to me

Hi.

I was looking for a rudimentary laptop to do some onboard diagnostics on my
cars. My neighbour was kind enough to loan an older Presario 1255 to me,
and it did the scan flawlessly! I decided to buy the laptop from him and
now wish to upgrade the meager 32mb of hardwired memory to its max of
60mb -- with 128mb.

My question is: pc100 backward compatible with the "suggested" pc66? If
so, will any 128mb PC100 144pin Sodimm sdram work in this laptop? ..say a
stick from an Armada M700?

Sure appreciate your input.

Wayne

The 1255 that I used to have was REAL fussy WRT memory. Only worked with
PC 66.
Traded mine for a couple of desktop machines.

Hmm. I wondered about that as I was on Comtread.com site and they spec the
1255 at this: http://www.comtread.com/results.html...e=3&Submit1=Go
According to them their pc100 works the same as pc66. This stick they offer
seems generic to most all other applications. The Kingston memory site (and
others) however, is really specific ..but it did raise a few flags. That's
why I'm polling.

So thanks, Steve.

I wonder if others in this group had a similar experience with theirs..?

Steve is correct. PC66 only. I recommend Crucial for all Compaq/HP memory.
Here is the link to your 1255. Only 64MB SODIMMs are available.

I'd like to take full advantage of the maximum of 160mb 9by using 128mb),
which still is rather limited.

Seems Kingston also still provides pc66 at 128mb: KTC-p1900/128 for this
1255 laptop.

Damn. Really too bad the much more available pc100 does not appear to work
as I was led to believe it was backward compatible. I thought it would just
be a matter that the laptop doesn't take advantage of the speed is all (?)

This is not unusual, whether notebook or desktop computer. A lot of the older
chipsets were designed before speed grades faster than PC66 were available, so
the chipsets are constrained to only recognize PC66. In fact, early, early PC66
memory does not have a serial presence detect (SPD) circuit, which tells the
motherboard the speed of the memory... Ben Myers

Interesting. Where can one round up info on the specs on the guts of this
Presario 1255? Is there a link to Compaq (or other) that will detail that
info, what components went into the laptop. ie: specific CPU and m'board
manufacturer and models, etc. I found a Compaq link to service and
maintenance of the unit but no specifics as (for instance) on the IBM site
for all their notebooks.

Thanks, Steve. Been through the Compaq corporate site. However, the other
links you sent are quite interesting. But I still need more specifics on
the motherboard and main chipsets, etc. as applies to the 1255's AMD K-2
that's on it.
As well, Mike's site doesn't really chase down many results of any dip
changes. That could be dangerous without knowing the details of other
product parts within the laptop. Be great to read some others comments on
what they did on the board and what the results were..
How will any of this change my pc66 directive to a pc100?

The MB was Compaqs own design. Made by Mitac I think, been a while since
I had mine opened up.
Chipset was Nvidea and it had S3 sound.

If you want to find out more info grab a copy of SiSoft SANDRA. Run it
and it will outline all the parts in the machine.
As for upping the bus speed it cannot be done, the only options on the
board were 60 or 66 mhz,
