DD3 not working in dual channel Tags: Memory DDR3 Dual Channel Corsair Last response: May 3, 2010 9:42 PM in Memory Share serialthriller May 2, 2010 8:21:40 AM Hi All, I have installed two sticks of 2GB DDR3 but the PC is still running in single channel mode. How do i enable dual channel? The harware is: *MSI P55-CD53 *Intel core I5 *Corsair , XMS 3, ddr3-1600, 1.65v, 9-9-9-24 *Corsair , XMS 3, ddr3-1600, 1.60v, 9-9-9-24 More about : dd3 working dual channel Lmeow a b } Memory May 2, 2010 8:49:27 AM Try sticking both RAM slots in the black slots first. If it doesn't come up as dual channel, then stick them in the blue slots and see if it works. serialthriller May 2, 2010 10:00:33 AM thanks, but it did not work. I tried all possible combinations. The only the way PC starts is if I put one stick in the first blue slot and the second stick in the first black slot. Any other other combinations just gives me beeps and then black screen. Any ideas?

Hope this helps serialthriller May 3, 2010 9:42:05 PM Thanks to all. Problem solved. I put one stick in at a time. Put one in, boot up. Then power down, add another stick and start up.
