Adding RAM to an Intel motherboard - what's the max?

I've got an Intel D865PERL motherboard with an Intel P4 2.8 processor and
1Gb or RAM (a pair of GB). I'm looking to upgrade the memory and have
looked at the useful crucial.com site, which advises that 32-bit versions of
Windows will only recognise, and more importantly use, between 3 and 3.5GB.

Is this true? In which case, there seems little point in putting 4GB on my
Windows XP Pro machine...

Thanks in advance.

What are you utilizing the computer for?
The reason I ask is that there is probably little point in your putting more
RAM in it from the "what you actually would use" standpoint anyway...

Unless you use memory intensive software ( Virtual PC, Graphics editing )
you're unlikely to need that much physical RAM. To keep a balanced
hardware setup, I'd save my money and invest in a newer Motherboard/
CPU & RAM sometime later. And yes 32-Bit Operating Systems have
a hard limit on how much RAM space they can address.

Yes, it's true that XP cannot use the entire 4GB.

There is advantage in putting 4GB of RAM in your machine - you can't raise
your RAM to 3.5GB.

It's true. See http://members.cox.net/slatteryt/RAM.html for a
discussion.

It's not clear from your description just how much RAM you currently
have ("1GB", "a pair of GB"???). If you currently have 2GB or more
it's not very likely that adding more would do you any good unless
you're using some VERY RAM-hungry apps (image or video editing, for
one).

1 Gb of RAM should be more than enough for most applications. The only
reason to add more than this is if you are doing something that really needs
it, such as editing high definition video. Otherwise stick with 1Gb - you
are unlikely to notice the change.

Thanks to all for the helpful input, and apologies for the confusion. To
clarify, I have a pair of 512MB sticks at the moment - 1GB in total - and
I've noticed a significant slow-down on my machine since upgrading some
applications: Dreamweaver, Fireworks and Photoshop all open and run
significantly more slowly than their earlier incarnations.

I also notice significantly more HDD access while I'm waiting for these to
open, so my thinking is that I'll leave the two 512s in there, and bung in a
couple of 1GB sticks, taking the total to three. Does that seem to make
sense?

sticks = memory module?
bung = install?

Just curious.

Yup.

you can research your
genuine motherboard at
the genuine intel website.

also, you can email their
sales rep to inquire what
applications require max
memory engineered into
the mobo and buy the
amount you require.

however, many, if not all
off-the-shelf software are made
for the average user and
computer.

it is not to say that software
could not be designed/coded
to use maximum memory. but
this software wouldn't be sold at
walmarts, amazon, etc...
