    Hi just trying to upgrade my memory and having difficulty, can anyone advise? Machine is a 2.8 quad core mac pro, it came with 4gb of RAM on 4 sticks of 1gb each, I bought 4 gb on two sticks and am having difficulty getting them all to work. Whichever way I configure them the bottom riser seems to have a red light and not be recognized. Right now I have 6GB all off the top riser. Hmmmm?

    Any advise appreciated! Tom

    How old and what version is your Mac Pro? Did you buy RAM that is supported by your Mac?
