ASUS P5E Motherboard
ASUS P5E Deluxe Motherboard
Both have 4 DIMM slots and support a maximum of 8 GB(2 GB X 4) of RAM.
Both use 1.8 volt, Unbuffered, Non-ECC, DDR2-667/800 modules.
The HP Compaq dc7900 uses modules with the same specs.
If those 1 GB modules aren't working in your ASUS motherboard, I'm guessing it's a hardware issue.
