What do you mean set for 2 sticks and only have one? It should auto detect the ram.
I mean for two sticks you need to make some changes. And no, it will not automatically always get things correct or automatically pickup the information for two sticks.

Use one stick and go in the BIOS and set your MCH to 1.2-1.24 and make sure static tread is at least 9 for now, and trfc at least 54 for now, set your ram voltage and then save and shut down and put in the second stick

Of course, yes your board may be bad, did you UV mark it when you sent it in for RMA the first time to be sure you did not get the same board back? Just wondering as it has been known to happen with many companies and products
