Generally that limitation is a function of the BIOS. XP and Vista 32-bit are limited to 3Gb in any event, so you are already in pretty good shape. ... Thinkpads_User

the design of the motherboard will be such that it cannot address chips larger than 1GB each.

The chipset is the final limitation since it restricts the number of RAm channels available. The OEM can make the restriction even smaller if they only supply a certain number of slots.

No way around these limitations.

I hope this helps !

I wish people would stop saying that -> it's wrong.
-
The PHYSICAL memory limit for ALL Windows 32-bit OS's is 4 GB. --> FOUR GB!
-
- Slightly less is -AVAILABLE- to Windows ,,, But the -LIMIT- is still 4GB.
[That does not include Server versions that can use PAE.]

Dell Inspiron 9400 uses an Intel 945PM Express Chipset.
-
The Intel 945PM Express Chipset fully supports 4GB of RAM.

Dell's documentation was written before 2GB RAM modules became available and were never updated.
- That happens often!

Your Laptop DOES support 4GB of RAM.

Thanks!!! That's what was confusing me.. I knew the chipset would support 4GB, I couldn't understand what was limiting it. Many thanks ;-)
