first of all you should use parts that are natively compatible with your motherboard and processor. The RAM memory needs to have the Serial Presence Detect (SPD) for 1066MHz at 1.5v.
The POST codes that you are receiving are part of the initialization on a normal POST sequence, so I recommend you to take your motherboard out of the chassis, using the Intel(R) provided Heat Sink, one RAM memory module, the power supply and the video card try to boot the system. Nothing else should be connected.
Please note that the motherboards that are sent from the warranty return center are tested before they leave, so it is weird that you received a bad motherboard.
