Board may not like your RAM.
Assuming you can't get into the OS consistently...
Power up let it BSOD and restart it using the GoButton until it beeps. Should be a momentary beep not a sustained one. If it POSTs' use Delete to get you into the BIOS and then set RAM to manual and drop it to 1333 to see if that will get it to clear up.
I had this problem when I went from my Dominators to my GSkill Snipers. I had no issues with Ripjaws. But my Snipers didn't register with the Board and I had to use the GoButton to force it to run at base value. It could be also that your RAM is bad. Not saying it is but it wouldn't be the first time someone put good sticks in that failed immediately in a new or slightly used board.
If the above doesn't do it, make sure your standoffs are tight to the tray and make sure that there are no errant unaccounted for standoffs that may cause a change in the traces allowing power to jump from the board to an ungrounded location. I had this happen to me when I first built this system. My 932 came with the standoffs in place, it looked like there were only 9 of them in place but I had BSODs' and thought it was my H50 getting too much contact on the CPU then finally I pulled the board up. Lo and behold there was standoff behind the RAM slots. That's what I get for building a system with zero sleep beforehand.
