    @ white slots

    Well guys, read the manual, its on page 17, you MUST populate the white slots (DDR3_1, DDR3_3, DDR3_5) at first if you want to run triple channel. Else the memory controller switches to dual channel mode and you lose one stick.

    It is no wired issue, its designed that way.

    I am getting the same error but it does not work, even when i try using the 1st white memory slot to test one stick of 2gb corsair 1333 mhz ram on my ex58-ud5 motherboard.

    I am getting the following post error code on the mobo: 29

    Video does not work!

    My system was working just fine until I replaced 3gb of Patriot Ram with 6gb Corsair. and also I upgraded the video card from 256 to 1 gb Evga geforce card. Now, I am not sure if i will be able to recover the system to its original state.

    Anyone able to resolve this issue? any suggestions would be very much appreciated. Considering RMA.. thanks,
