In What Order Should Memory Slots Be Populated?

The answer to this question depends on the type of computer motherboard and memory slots you have. If you have a dual in-line memory module (DIMM) board, the slots should be populated in a particular order to avoid overloading the power or data lines.

The order goes like this: slot 1, slot 3, slot 2, slot 4. If you have a single in-line memory module (SIMM) board, the slots should be populated in this order: slot 1, slot 2, slot 3, slot 4.

If you’re not sure which type of board you have, consult your motherboard’s documentation or look up its model number online. Once you know which type of board you have, refer to the documentation that came with your memory modules to determine which slots to populate first.

In general, it’s best to populate all the slots on a motherboard with identical memory modules. That way, if one module fails, you can replace it with an identical one without having to reconfigure the rest of the modules.
