Hi guys this is going to be long winded so if you wish to only read my problem skip to the next paragraph., I have an Alienware Aurora R4 built in 2013. I can post my service tag if needed although i imagine my warranty has expired. I am a huge Flight Simulator user and for those of you who know Microsoft Flight Simulator X it is very CPU and Memory intensive. I shoot for realism with my sim so about a year ago I added another Nvidia GTX 680 to my computer and my frame rate was better what wasnt quite the 30-35 fps I was looking for. So a couple moths ago I tried overclocking the processor further. The processor was stable at about 4.5 Ghz but it would crash eventualy. I came to the conclusion that i was RAM limited. So in the past week I have done my research and bought some new RAM. I know my motherboard supports a max of 32gb at 2133Mhz so I bought a 32 gb kit from Corsair. It is a 4x8gb Corsair Vengence pro DDR3 2400 Mhz. 

My problem is this: The computer will not POST when all 4 of the Corsair Sticks are installed. The computer turns on and all the fans and lights act like the computer is running normally but my monitors stay black. The only way I have been able to get the computer to run properly is if i install 3 of the Corsair sticks and 1 of the old Micron sticks. When I run it this way it clocks the RAM down to 1333Mhz and it recognizes all 28gb of RAM that are installed. I have tried setting the multipliers and voltages manually and i have also reset the BIOS multiple time via the CMOS. I contacted Corsair and they said it was a motherboard incompatibility and they said to contact Alienware. However, they had no explanation for why the 3 and 1 worked. Thus here I am. I will post my specs below. Any help or comments on the matter would be greatly appreciated. If you need additional Information please contact me. Thanks in advance.
