I just checked the Kingston website and for your motherboard, they had this to say regarding DDR 400MHz models:
"Virtually any configuration up to 2GB can be reached using any combination of Kingston's 128, 256, 512MB, and 1GB modules."
Basically all that means is that your motherboard supports up to 3 GB of RAM, but if you're using the Kingston ValueRAM you'll only be able to upgrade to 2 GB of RAM.
