I just got that new memory set {Corsair CMX8GX3M4B1333C9 DDR3 1333MHz 8GB Kit CL9 DIMM } with the following system: msi x48c platinum; Intel core 2 quad Q9450, 2.66 ghz; geforce evga gtx 260, 216 core superclocked with a 500w power adapter. I have the corsair h50 cooling system for my cpu. After installing the memories, I never be able to boot up my system. I always got that 3 long beeps with no pic. on the screen. Let me tell you the motherboard works great with dd2 set. Is there any suggestion or modification that needs to be done on the motherboard to have it work???
