There is a problem with Phenoms and DDR2 1066 when for modules are installed. You can get that configuration stable with an high quality board and some voltage tricks. If you have problems at lower speed and 4banks, you have a crappy mainboard. Maybe increasing voltages a bit (0.05 to 0.1V) will help you. It did for me with one certain Asrock board.
