I got the same trouble for my hp xw6600 too. I'm running VISTA 64bit . I install four 2GB sticks (same brand same specs) in slot 1, 3, 5 and 7.  I am getting an error (204: memory loaded incorrectly) for slot 5 only. Does it mean the memory stick in slot 5 faulty? All the other three slots working fine.

What happens if you put in the module from slot 7 into slot 5 and vice versa? Does the computer now complain about the module in slot 7?

Just curious why did I get the 204 message telling me memory loaded incorrectly but not 201 Memory Error or RAM failure.

Well, every RAM module has a 'SPD'-chip on it that tells the BIOS its memory type, speed and all other necessary things. Maybe this module responds differently as the other three modules and so the BIOS recognizes the module correctly but cannot proceed with the data it received from the module, but that's just a guess.

By plugging in the module in a different slot you have ruled out the mainboard as the cause of the problem, because the other module worked in slot 5.
