Which Slot Should I Put Ram In?
Which RAM Slots Should You Use? – The safest and most effective way to determine which RAM slots you should use is by checking your motherboard manual as it can be different for every motherboard. But, in general, the rule is as follows: If you have one RAM stick, you should use the slot furthest away from the CPU socket regardless of the number of RAM slots that your motherboard has. If you have two RAM sticks, you should use the slot furthest away from the CPU socket and the slot one slot away from the CPU. If you have three RAM sticks, you should use the three slots furthest away from the CPU socket. If you have four RAM sticks and a four-slot motherboard, then you can just populate all four slots with all four RAM sticks. If you have more than four slots on your motherboard, then you either have a server motherboard or a very fancy high-end desktop / workstation motherboard.

These boards might also support triple-channel (rare) or quad-channel memory support.

- If you for some reason only have one RAM stick available, it can go anywhere. If you have two RAM sticks, they have four potential spots they can go in now compared to the two before. You should put the sticks in the slots furthest away from the CPU for maximum clearance. But make sure that both sticks are only one slot apart and everything should be alright. If you have three RAM sticks, just put them in the furthest slots right next to each other. If you have four RAM sticks, you can put them all next to each other or space them out for symmetry. If you have a motherboard that supports quad-channel memory, then it might be required for you to have the RAM sticks in a certain pattern. You have to consult your manual for this one. If you have five RAM sticks, it’s the same as four, just stick that extra stick somewhere in-between. If you have six RAM sticks, put three on each side for symmetry. If you have seven RAM sticks, it’s the same as five, just stick that extra stick in there somewhere. If you have eight RAM sticks, then just populate all slots.
All of that said, I really don’t recommend you use uneven RAM stick configurations (3, 5, 7). You’ll most likely be mixing and matching RAM for configurations like that, so the chance of running into issues increases because of it. You’ll also screw up the multi-channel configuration with an uneven number of RAM modules. Image Credit: ASUS In this case, I highly recommend that you look at your manual. What I’ve said above for motherboards with eight RAM slots could apply here, but it might just as well lead to instability as well—especially if you have odd numbers of RAM like three, five, seven.
Doubly so if you have a motherboard that supports dual CPUs . In motherboards like this, each CPU controls half of the available RAM slots. This means that if you only populate some of the slots, say, four RAM slots on the first CPU’s side, the second CPU won’t have any RAM of its own and will have to go through the first CPU to get any RAM for the tasks that it might be performing, which can lead to major slowdowns.
So it’s always best to consult the manual first. It’s hard to give info about motherboards like this because there are so many potentially different configurations.
Does RAM slot order matter?
Does the RAM slot order matter? It can, but it depends on the motherboard. Some motherboards require you to use specific slots depending upon how many ram cards you have. In general, however, 1 card by itself can go anywhere.
