ThinkCentre A51 8131-1NU support for maximum amount of memory

[ Edited ]

I have a ThinkCentre A51 8131-1NU that came with 1.5 gigs of RAM.  I just replaced it with 4 Gigs of RAM (4x1 gig sticks).    however the BIOS only recognizes 3 gigs of RAM.  I have installed the 64 bit version of windows 2003 and it too also reports only 3 gigs of RAM.  How can i get the BIOS and OS to recognize the entire 4 gigs?

 

Here is the specs for the ram i installed:
