server 2003 SBS 32bit can and will run on 4gb of ram, it is not only 64bit OS, although 64bit can use the ram more efficiently then 32bit.

Sure, it WILL run. I don't recall saying that it won't. But the amount of RAM visible to the server system resources will be closer to 3GB. +/-, depending on hardware.

SBS is limited to 4GB as maximum. But since on majority of hardware it can't use more than 3GB, I think that installing the 4th GB is a waste of a gigabyte. A different side of discussion is whether the hardware setup allows use of the extra gigabyte for RAM error correction. If it is supported, excellent, go for 4G, otherwise - decide yourself.

Sorry if you think this is off-topic, just wanted to be a little more informative. Thoughts and considerations of an active SBS administrator for a few customers of mine.

It uses 4 GB of memory.
About 1/2 GB (+/- 1/4 GB ) is reserved for system use and is not available for applications but it's still there and still being used by the system.

All Windows 32 bit OS's are limited to 4 GB.
- Some can be extended to 128 GB using PAE.

64 Windows bit versions vary between 4 GB and 2 TB ( TB = Terabyte )
