    You need to put the RAM into slots 3 of the top and bottom. Because you are installing "Pairs". Take the Stick out of slot 4 of the bottom half, and put it into slot 3 of the top and both should be reconized.

    Essentually 1 on top and 1 on bottom go together, 2 on top and bottom go together, and so on. So you need to put both chips into slot 3 if 1 and 2 of each is taken up.
