All P35 motherboards can run both Core 2 Duo's and Core 2 Quads, although a couple need BIOS updates for the quads.

I recently built a system for someone with 2x1 GB plus 2x512 MB, using an Abit IP35, with 1.5 GB per channel in dual-channel.
3GB for RAM is not the best RAM configuration as it prevents operation in dual channel mode. For dual channel mode you need to install 2 or 4 identical sticks of RAM.
