For starters, how much RAM should you now have installed and how much RAM is actually being shown in Activity Monitor? Next, in System Information, in the Memory section do all the DIMM's appear and is their status "OK"? Finally, what slots did you install them in (we don't know how many slots you have because we don't know which Mac Pro you have) and with what other DIMM's, if any. On the later Mac Pro's, the red light that's lit identifies which DIMM is causing the problem. Do you know which red light is actually lit?
