I just installed 4x1gb OWC ram onto my top riser, adding onto my previous 2x512(dimm 1&2) + 2x1gb setup (which is now on my bottom riser). My previous setup had no problems and OSX detected the ram just fine but now with my previous setup on the bottom riser, OSX only detects the top riser with the new OWC 4x1gb ram. My former setup now displays a red LED light on the bottom riser.
It does seem to detect all RAM when the risers are switched around but what did I do wrong to make it not work the other way?
