384MB

?? How can that be, though? He's already got 512 MB installed, doesn't
he?

Good point.

Both these memory upgrade locations indicate a maximum of 384MB in 3 slots.
Getting information from www.hp.com is a nightmare and is one of the reasons HP computers
suck.

Everywhere I searched on Presario 5645AP specifications report 3 banks, 128MB is
the largest use can use in each bank and 384MB is the max.
What is the motherboard exact make/model used for the PC?

You can also check out: http://www.crucial.com/ to find out what's installed and
how much you can install.

Mobo never change before. I would have thought that I can insert another 256
mb in the 3rd bank but it will give a '\system32\pci.sys error" . Ittook
quite a while to get it going with 2 rams again. The pc is showing 512 mb of
ram so at 128mb of ram per bank can't be right. It just shows how things are
covered up duirng the manufacturing/documentation process. Anywhere thanks a
lot for your time and will just live with 512 mb

At the time the computer was built 128mb modules were probably what you
could get. I don't doubt that 256mb modules work also but I bet that they
were not tested in the machine at the time it was built so the manufacturer
set the specifications in the docs according to what they could test and
therefore support. The various websites that sell memory have only the
manufacturer's docs to go by so when their software looks up the mobo data
it reports the last known mfg specs. I'm sure they were never updated.

I should think that three 256mb modules would likely work but the chipset
drivers may only support 512mb and the only way to tell is try it. It is
possible that 512mb would be the limit because that was the max supported by
Win9x/ME (at least at the time).

That's a good explanation. However the following was noted by the OP...
"I would have thought that I can insert another 256mb in the 3rd bank but it will give a
'\system32\pci.sys' error"

Therrfore the hardware probably has limitations as well. Maybe a BIOS upgrade could correct
this.
But I doubt one exists.

That's what I meant by the chipset drivers. It is probably not the BIOS.
But there would not be any recent updates.
