    I just bought a early 2009 MAC Pro and it came with 3GB of RAM, I ordered 3 2GB sticks of memory to replace the 3 1GB sticks that I had in there from Kingston. I turned off the unit, I popped the little levers and pulled the memory out of slot 1, 2, 3 and then replaced the memory with the new Kingston in slot 1, 2, 3

    One of the sticks in is not working at all and I get the RED LED light no matter what slot I move that chip to. So I am running on 2 of the new Kingston memory chips.

    Can I mix the memory and add the 1GB into slot 3 and 4 with slot 1 and 2 full of 2GB chips?

    Also how to I run the memory utility again? I went to /system/Library/CoreServices/ and then I see the program Memory Slot

    How do I run this? I'm used to no spaces and I type ./then program name

    You seem to have done the right things (also see pages 55 and up, which recommends the same in the note).

    To start the utility, just double click on the file name in Finder :D OR for command line use, use double quotes around the "name with spaces" <-- like this.

    It is possible a memory stick is faulty -- you can check that by putting it in a working slot. Good luck!
