Which RAM Slots To Use

Ram Slots

Have you bought a new RAM stick and are unsure which slot you should use to connect it to your PC? Although the process seems complicated, determining the correct slot is not that complicated.

Quick Answer

If you have a single RAM stick, it doesn’t matter where you install it on the PC’s motherboard. However, try to position it adjacent to the processor channel. If you have two sticks, install them in A1-B1 or A2-B2 positioning. For a better understanding, you can consult the motherboard manual.

We have compiled a comprehensive guide to determining which RAM slots to use on your PC. We will also discuss some fixes for the RAM slot not working on your computer.

Which RAM Slots To Use

The best way to determine which RAM slots to use is by checking the manual for your motherboard, as RAM sticks positioning varies depending on the type of motherboard you own. But generally, you can also follow the rule based on the number of memory sticks.

If you have a single RAM stick, the slot at the maximum distance from the CPU socket should be used. This way, your CPU system will remain the coolest. For two sticks, install them in A1-B1 or A2-B2 positioning, meaning use one slot that’s furthest away from the CPU socket and the other that’s one position away from it.

Three RAM sticks should be positioned in the three slots at the maximum distance from the CPU chamber. You can place all four memory sticks into the positions available on a four-slot motherboard.
