I have a Dell 1501 Inspiron. According to the tool on the Crucial site I could use a memory module kit containing 2 GB, 1 on each piece of memory. I followed the directions, released the first memory and was expecting the 2nd one to be directly below. A-DIMM was replaced with ease. But, B-DIMM is located adjacent to and not directly below A-DIMM. The only way to use the 2nd memory in my kit is to plug it in upside down to insure the keyed part of the board will fit. Is this o.k. I've not tried it yet. Or is there another type of memory possibly. Mine is side by side not up and down.
