I bought a server motherboard off ebay and it said it needed ddr2 so I ordered the ddr2 and the notch didnt line up either way I put the ram and I am not a beginning enthusiast. So I tried normal ddr, ddr2 from another computer, even ddr3 and none matched so I assume there is some sort of special server ram I need so does anyone know what that might be?

I don’t know the exact model but I know it’s an Intel motherboard with two dual core xeons and supposedly supports ddr2 ram. And does the whole buffered and unbuffered thing affect physical aspect?
