just purchased a 2009 dual processor tray comes with 6x 1GB memory from ebay Plug in to my macpro 4,1 (updated to 5,1 firmware) press the power button, white led stay on all the time, fans running normal, no chimes, no boot, no display. tried remove all the pcie cards and hdds, only left gt120 GPU still no go. Any idea? currently plugged in my previous processor board im typing now. could be a defective board? did not see any error led on the board.
