That's interesting. Assuming that your machine has a 440MX chipset,
according to the Intel 440MX datasheet and design guide, the chipset
itself supports 128 Mbit modules (128 Mbit x16 = 256MB), but is limited to
256MB of system memory. Because the MX is based on the 440BX core, perhaps
that 256MB limitation isn't entirely accurate?
The BX chipset supports up to 4 banks of 256MB (8 rows, or 4 double sided
DIMMs) vs the MX which supports only 2 banks (4 rows, or 2 double sided
DIMMs). Since the 440MX appears to actually support up to 512MB of
addressable memory, assuming all the signals are routed correctly, it
might very well be possible to replace the chips on the motherboard with
higher density chips and top the system out at 512MB.
Oddly enough, the 440BX datasheet only mentions 64 Mbit modules, even
though I can state for a fact that the 440BX supports 128 Mbit modules,
since the machine I happen to be sitting at right now has a 440BX chipset
with 128Mbit (256MB) modules installed.
Tsk, tsk Intel...you need better writers ;P

Intel 440BX 82443BX datasheet
http://developer.intel.com/design/chipsets/datashts/290633.htm
It is a Intel 440LX chipset (Dell Dimension
333D.)
According to Dell the system only supports up to 128M DIMM.
According to IBM, my Thinkpad 1200 series model 1163G (Pentium-IIIM)
only supports a single 128MB SO-DIMM for a total of 192MB RAM.
However, I bought it from a shop where I knew the staff well - I used to
work there - and they let me try a variety of DIMMs in it before I took
the machine. We had no difficulty finding a 256MB DIMM that worked fine.
Result, 320MB RAM, enough for Windows 2000 to run well.
Don't believe what manufacturers tell you. They don't always know.
