The aforementioned MOBO won't accept my 16 GB of GSkill Ripjaws RAM (The debug tool displays a "53: no usable memory detected"). It will not allow me to get to BIOS. I checked the GSkill website, and it confirms that the type of RAM is compatable with the motherboard. Any help? This is the second MOBO i've had do the same thing (I returned the original one, hoping that the problem was just faulty memory slots).
