Adding memory is one of the easier ways to boost your PC's performance. Buy suitable RAM, then open your PC and firmly seat your new RAM in the RAM slots on your motherboard.
Why 2 & 4? To prevent any possible interference with the large CPU air cooler. To upgrade or replace your PC's RAM, consult your PC's manual or use Speccy to identify what kind of RAM your PC uses, and how many slots it has available. 1 & 3 on one channel, 2 & 4 on the other channel.Ģ. Because that's the way the slots are wired. Why is that happening? And whatever is happening, is this the same reason why manufacturers of motherboard in their QVL list will say 'X ram model will work in X slot but not in Y'?ġ. I've seen lot of issues where people would put only 2 RAM sticks into 1st and 3rd slots and their systems would not boot up but swapping them to 2nd and 4th slot would solve the issue.
I know that most consumer grade motherboards and chipsets support dual channel so because of way in which controller is connected to RAM slots there might be preference for 2nd and 4th slot over 1st and 3rd slot Why is that? And please, no 'because manual says so' answers. Since long time already, we are told, when assembling PC and where motherboard has 4 RAM slots, that we should insert first pair of RAM into 2nd and 4th RAM slot first (or other two assigned RAM slots) and only after that, if we get 2nd pair we should put it into 1st and 3rd slot.
