Which RAM Slots to Use?

Many people were asking about the methods to Which RAM Slots to Use which are why I have come up with this article so that you can get the core knowledge.

So you bought some new RAM sticks, but you don’t know where to put them? If that’s the case, you have nothing to worry about. You’re in the right spot.

As a PC builder with a lot of experience, I’m here to help you install your RAM so that you get the best performance you’ve always wanted.

The question now is which RAM slots to use.

You can put one RAM stick in any slot, but it’s best to put it right next to the processor channel. Install it in A1-B1 or A2-B2 format using two sticks. Also, you can look at the manual for your motherboard to get a better idea of which RAM slots to fill.

Still, confused and want to know more about how to install RAM the right way?

Which RAM Slot Should You Use?

In this part, I’ll tell you which slot to choose based on the RAM sticks you have.

Whether you only have one stick of RAM or several, you’ll know which slot on your motherboard will work best.

For a Single Stick

If you only want to put in one RAM, you don’t have to worry too much. First, check to see how many slots are open. If there’s only one slot, you just have to put it there. Check your motherboard’s manual to see if it has more than one slot.

If there were no instructions in there, you can put it where you want.

But before you install, make sure you’re installing the right RAM that works with what you’ve already got.

For Multiple Sticks

When installing more than one stick, it’s important to keep in mind things like the color of the slots, the RAM module, and how well it works with the motherboard.

If your motherboard has more than one RAM slot, it’s possible that each slot is a different color. Let’s say you are using a four-channel motherboard and colored slots. Use the other slots if you want to add more RAM.

But if your motherboard doesn’t have color protocols, all you have to do is read the manual and install the RAM based on what it says.

How to install RAM

So, you know where to put your RAM and you’ve bought some new RAM to speed up your PC. The next step is to put the stick on your computer’s mainboard.

Installing RAM

RAM isn’t the hardest thing to put in. But if you don’t do it carefully, it can cost you. So, I will tell you to read this manual carefully and do what it says.

You need to make sure of a few things before you install. I am giving you a list of these things to do to get ready.

  • Make sure to turn off your computer.
  • Place the computer case so it’s easy to get to.
  • Clean your motherboard of dust.
  • Try not to get static electricity.
  • Try not to use your bare hands to connect things.

Once you are sure about these steps, you can move on to the next ones.

Here’s how to put RAM in:

  • Find the right slot for a single channel: If you are using a single-channel stick, look at the label on your motherboard to find socket 1. (also known as socket 0). Use the slot right next to your processor. If that one is taken, try the next one.
  • Find the slot for dual channel: If you have two memory sticks and four slots on your motherboard, try not to put them next to each other. Try putting them together like this: (!+3) or (2+4). It will help them do better in school.
  • Follow slot order: It’s important to make sure that you install the RAM in the same order as the sockets. Make sure that the RAM you install is the same type, has the same amount of space, and has the same chip. If you do these things, the “interleaving” problem will be solved in the long run.
  • Open the RAM slot: You need to open the RAM slot before installing. You can do this by opening a small clip on the socket of the motherboard. Whether you need to unlock one or two clips will depend on the model of your motherboard. To unlock clips, you just need to push them outwards firmly. Don’t push too hard, remember. You could break the clip if you do that.
  • Put in the RAM stick: Take the modules out of the box. Don’t touch the green boxes, which have exposed wiring, unless you have to. Match the cutout on your RAM to the cutout on your motherboard. Check it twice before you put it in. That’s right, once you’ve matched them up correctly, you’ll have to push the stick onto your motherboard until you hear a nice “click.” But keep in mind that you need to push your RAM in from the top down in order to do it right.
  • Check to see if the plug is locked: Make sure you put the memory stick in the right way. Check again to see if the socket is locked the same way it was before ( before opening the slot). This is just a safety measure. If you put the RAM in correctly, you will hear it lock, and you won’t have to check it again. But it’s always a good idea to check.

If you’ve done these steps right, close the computer case, plug in all the wires you need, and turn the computer on. You might have to restart your computer a few times for the changes to be picked up by the motherboard.

Here’s how to make sure your RAM is in the right slot:

Method 1: Use Windows Task Manager

Using this method, you’ll need to use Windows’s task manager to check which memory slots are free. Follow the steps in the right way.

  • Open task manager: Type “Task Manager” into the search box in Windows and click on the first result that comes up. Or, you can right-click on your taskbar and choose “task manager” from the menu that appears.
  • Open the performance tab: When the task manager opens, click on the “performance” tab. You will see a list of things like CPU, Memory, Disk, etc.
  • Click on memory: From the list, click on “memory,” and you should see a section called “slot used” in the bottom right corner.

From there, you can always see how many slots you’ve already used and how many are still open.

Method 2: Use CPU-Z Utility

If the first method doesn’t make sense, you can use this common tool to check your memory slot quickly.

Just get the software and install it, then do what I say.

  • Open CPU-Z: To open, double-click the software icon.
  • Select the “SPD” tab: When you open the software, there will be more than one tab on your screen. From there, click on “SPD.”
  • Choose “memory.” Section: Click the down arrow key after opening the “SPD” tab to open the “Memory slot selection” section.

You’ll see that the drop-down menu lists all of the memory slots.

FAQs for Which RAM Slots to Use

Can I put RAM in slots 3 and 4?

Yes, it will add more RAM. You should add as many as your motherboard can handle. But instead of adding three, it would be better to add two because dual-channel memory is faster. The dual channel won’t work with the third stick.

Is it better to use 2 or 4 RAM slots?

Should I use 2 or 4 sticks of RAM? In dual channel mode, 2 sticks will run faster than 4 sticks on their own. Dual channel mode is the best and fastest way for your RAM to be set up. If you can, I would go with two sticks in dual-channel mode.

How do I arrange my RAM in slots?

If your motherboard has four RAM slots, it’s likely that you’ll want to put your first RAM stick in slot 1. Slot 2, which is not next to Slot 1, is where the second stick should go. If you have a third stick, you would put it in Slot 3, which is between Slots 1 and 2.

What is the best RAM configuration?

For streaming and making content, we recommend a RAM configuration with either two or four channels and at least 32GB. This makes sure you get the best performance out of the game you’re streaming and gives your viewers a smooth, lag-free viewing experience.

Is 4 RAM sticks slower than 2?

In dual channel mode, 2 sticks will run faster than 4 sticks on their own. Dual channel mode is the best and fastest way for your RAM to be set up. If you can, I would go with two sticks in dual-channel mode.
