I just recently upgraded from 2x2 GB DDR3 1333Mhz sticks of RAM to 2x4 GB DDR3 1600 Mhz sticks. Windows 7 will not recognize the new RAM I installed it still says I only have 4 GB. Can anyone help me out? Could there be an issue with my motherboard? My motherboard is a:ASUS P7H55 -- Intel H55 Express Chipset w/ 8-ch HD Audio, Dual-Channel DDR3, Gb LAN, S-ATA, USB 2.0, 1x PCI-E 2.0 x16

I just tried doing this: I took out the 2 RAM sticks and tried putting them in the dimm slots one at a time and booting up..I found that dimm B1 is the only one that is recognizing the RAM..Dimm A1, A2, B2 all don't recognize it...why is this?
