Optiplex 320. Not detecting original memory anymore.

Question

Hi all, I just added 1 GB of Crucial memory to my 512 MB Optiplex.  It looks like it's detecting the new memory just fine, but now it no longer sees the original memory.  The BIOS show 'Installed RAM' is only 1.00 GB, but below that it shows 1.00 GB in DIMM 1 and 512 MB in DIMM 3  What happened to DIMM 2?...lol.  Anyway, I swapped the cards and the same thing happens.  I made sure they were seated correctly and that the clips clicked in.  I also just updated to the latest BIOS (1.1.12). Thanks in advance.

The maximum allowed is 2GB PC4200 533MHz non-ecc DDR2. What are the specifications of the Crucial memory?

Do you have a video card in the PCI-E slot? Take it out and see if you can see the full 1.5 GB.

No video card.  It has integrated video.
