Hello... I need help upgrading my computer's RAM. I want to increase it to 2GB. But I don't know the exact setup. Because there 2 different DIMM Slots ( DDR1 and DDR2 ), and they both have different Bus speeds. It is kind of complicated! Can I Install a (1G.B DDR1 at 400MHz) and (1G.B DDR2 at 300MHz) in the second slot? This is my Motherboard's Web Page.
