The 440LX chipset itself can support 512MB of SDRAM or 1GB of EDO, but
what you are running into is a density issue. The LX can handle up to 4
banks of double sided 64 Mbit x16 (128MB) modules, but Dell went with the
"small memory array" design that specifies 3 DIMM sockets instead of the
"large memory array" with 4 sockets. If the board is designed to spec, you
might be able to add more memory if you can find some double sided,
buffered EDO DIMMs, but I seem to remember those being difficult to
source.

According to Dell the system only supports up to 128M DIMM. m?n 2012-10-01 klockan 07:04 -0500 skrev

Which chipset does it use? I've run into many boards where the
documentation regarding how much memory the board could support was
wrong. Case in point, some of the AMD based Compaq systems state 384MB
max (3x 128MB) but in fact actually support 1.5GB (3x 512MB). Back in
the days of Slot 1 CPUs, Dell locked some their motherboards to certain
slower models of P2 CPUs with later BIOS revisions, so it is certainly
possible they did something similar with memory.
Any PII and PIII will support at a minimum 512MB of ram (even the
consumer chipsets), but as long as you have swap, 32MB or 64MB would
probably work. It's when you are running the entire OS from media
such as CompactFlash or SD card where you don't have swap that having
less memory can become a challenge with modern software (no X, gui,
etc). As cheap as second hand SDRAM modules are though, adding more
memory is the easiest solution.
Njaa, my mother's Dell Dimension machine from 1997 only supports 384 M
(3 memory module slots) IF you can get hold of some a bit unusual 128M
memory modules. Dell sold them with 1 or 2 64M modules :-( .
