What DIMM Slots to Use?

DIMM (dual in-line memory module) slots are the connectors on a computer motherboard that house memory modules (usually referred to as RAM). There are typically two different types of DIMM slots, those for standard size modules and those for smaller SO-DIMM (small outline DIMM) modules.

The number of DIMM slots on a motherboard varies, but there are usually at least two.

When populating the DIMM slots on a motherboard, it is important to ensure that the modules are inserted in the correct slots. There are typically three channels on a motherboard, and each slot is color-coded to indicate which channel it belongs to.

In most cases, it is best to populate the DIMM slots with matching pairs of modules. This means inserting two identical modules into each channel, for a total of six if the motherboard has three channels.

If only two modules are being installed, it does not necessarily matter which slot they go into. However, if four modules are being installed, it is best to put them in order from sLowest to fastest.

This means putting the two slower modules in the first and third slots, and the two faster modules in the second and fourth slots.

The reason for this is that when four modules are installed, they are accessing memory in a interleaved fashion. This means that each module is accessing every fourth bit of data from the memory chip.

If themodules were not installed in order from sLowest to fastest, this would result in somemodules having to wait for others to catch up, which would decrease performance.

In conclusion, when installing DIMM modules on a motherboard it is important to ensure that they are inserted into the correct slots. For best performance, four identical modules should be installed in order from sLowest to fastest.
