From my Tyan motherboard manual:
"The AMD-760 MPX requires a portion of memory to be reserved for PCI
devices. Allocation for these devices is dependent on the number of PCI
devices installed, and option ROM for each device. Common configurations
will see 3.5GB to 3.8GB of available meomory." There are also some MS KB
articles as well as discussion elsewhere - as has been pointed out: the
memory is used by the hardware.
My feeling is that if a person feels he wants lots of memory and has the
money he should install it and not worry about the little that's lost.
It's not the fault of MS.

This is not what I was told by Crucial tech support. I was told that
since Windows is using the addresses (not RAM, addresses) above 3.25 GB
the .75GB
of RAM that requires those addresses is NOT being used. Quite a different
thing.
Your USB bus won't run faster, IO won't happen quicker, your mouse won't
be
more precise. It seems there is no benefit whatsoever to the user in
having
the extra RAM. For all practical purposes, it's as good as not being
there.
If this is true, then companies, such as Crucial and MPC, that are
marking machines saying that there will be 4 GB accessible (meaning you
can use all 4
GB) are plainly misleading consumers.
My machine came with 256MB. I added 2GB more at the time of purchase.
That gave me 2.25 GB. It cost me over $250 to get 1 GB more to use for my
applications (2 DIMMs, 1GB each). Now I am exchanging that for 2 DIMMs of
512MB each (as Crucial recommended). That means it will cost me $130 for
.75GB (because I have 4 slots and the 256MB that shipped with the system
will
be unused.
In addition to spending a whole day trying to sort this out, it's going
to waste more of my time sending back the RAM and installing the
replacement, and push back a couple of projects.
It is inexcusible for MS and the other companies involved to state that
Win
XP can run a maximum of 4 GB. The upper limit is plainly 3.25 GB. If the
RAM
above that is taken for something that the user can't control or
reassign, then it is not accessible and it should be disclosed at the
time of purchase
so that time and money is not wasted. And people wonder why companies get
sued and force the government to regulate them. The amount of time, money
and
engery that they cost consumers must be staggering.
