Assuming that you have all compatible hardware from Intel Tested H/w list
Can you check in the System Event Log if it mentions anything critical?
It is unlikely for it to be the memory, as it is booting in Windows with a single memory module, then it must be something else possibly.
Again the error regarding in the Intel Active System Console will be logged in the SEL log.
Which cooling solution are you using?
Are you using any air duct?
Which system fans are connected?
Possibly someone who have experienced on the new board can point the errors to you.
Let me know how it goes.
