My ram is arranged like in the pic

And I heard that usually to run in dual channel you have to put the first two rams in 1st and 3rd slots and other two in 2nd and 4th slots and I putted them like that now ('cos the colors went like that too).
And I was just wondering is it now correctly 'cos Belarc Advisor shows different than it should be?
My mobo is MSI LTD MS-7091
