Motherboard DP45SG W/Corsair XMS3,DDR3,1333,attempt to upgrade memory and ran into issue,I ordered the same memory that is in the system and running now,upon receeit of the new memory after installing into slots I got three long beeps and no video,swapped out the memory and tried one stick at time,still got beep error,flashed the bios in recovery and nothing happens other than beeps,puzzling why old modules will work on board and new modules will not,no matter what slots I put them in.Considered the MB may have memory controller problems,but I am still able to use the old memory with same specs
