That page does not match my manual or the actual etchings of the numbers on the motherboard RAM slots
My slots on the motherboard reading them from left to right with the cpu at the top and the power connector on the right are labeled 4,2,3,1. My manual chart says 1 and 2 or 3 and 4 for Dual Channel mode.
As shown here in revision 1001 of the manual.
And the table here:
I don't know what revision of the manual you are using, but mine matches the etching numbers on the motherboard. Hopefully we are on the same page now. RAM slots 1 and 3 are not working at all now, RAM slots 2 and 4 are fully functional.
Question is what to RMA the motherboard or the CPU. I was hoping you would have some insight on this question.
