I have two sticks of 2G (2X2G) G-Skill Ripjaws. The motherboard is an Asus M4A79T Deluxe and the user guide sucks. My old motherboard (A8N-SLI) had me install 1 dimm in A1 & 1 in A2. This time around it looks like they want me to install 1 dimm in A1 & 1 in B1. I would think they should both go in the same channel. Anyone with the same motherboard have an answer? Thanks for any help.
They should be color coordinated. Although I did read where that was not always the case, but I can't remember which board/boards that was. I would try the first 2 slots, run CPU-Z to make sure it's running in dual channel-mode. If not try slots 1 and 3 (left-to-right) and then you should be good-to-go.
