What is the maximum allowed memory for XP. My motherboard can handle 4 gigs,
can XP?

Its the maximum the board holds for the recommended memory. 2-4 Gb is fine these
days so long as the graphics card is quite decent so not to start stealing RAM

One of my server boards can handle 32 Gb, but it only has 24 Gb installed

XP support upto 4 GB, but it may not disaplay that correctly due to some
problems,

32-bit WinXP can handle up to 4GB of RAM. But it won't be able to see
and use all of that. See http://members.cox.net/slatteryt/RAM.html for
a discussion.

Yes and no. The 32-bit version of Windows XP (I assume that's what you
have) can handle 4GB, however in practice it can only use about 3GB.

All 32-bit versions of Windows have a 4GB address space. However all
of them (not just XP) have to use some of that address for hardware
devices. After deducting that use (which varies depending on your
devices) you normally get about 3.1GB of remaining usable space.

What applications are you running that make you think you could make
effective use of that much memory? It's a very rare person running XP
for whom having more than 512MB to 1GB wouldn't be a waste of money.
Many people don't even need that much.

That varies a LOT. My machine sees 3.50 GB. It depends on your video
adapter, your BIOS and several other things.

Yes, it certainly does vary. That's why I said in the part of my
message you snipped, "After deducting that use (which varies depending
on your devices) you normally get about 3.1GB of remaining usable
space."
