Does it matter which ram slots I use?

78 / 100

The RAM slots are used for installing RAM cards into your computer. They are tagged with numbers or colors so that you can install the RAM cards in any order. This action helps to get the maximum performance from your computer. There is a common question in a newbie’s mind- “does it matter which RAM slots I use?”.

Well, yes, it matters. But, for normal usage, you can ignore the difference between installing RAM cards in different slots. But, when you use it for a heavy-duty purpose like running AutoCAD or Vista, you’ll see a huge difference in performance. 

All the major components of a PC are installed into the motherboards. Therefore, the motherboard manufacturers usually suggest you install ram cards in particular slots. Installing RAM cards in particular slots provides a more significant boost in data transfer and provides more FPS. Also, you can get more bandwidth by following the motherboard manual to install RAM cards in the mentioned ram slots.

Does it really matter which ram slots I use

Yes, it matters which RAM slot you use because of the manufacturing process of motherboards. The motherboards are designed to get the most performance out of your computer components. As a result, the motherboard manufacturers sometimes require you to install the RAM cards in specific slots. 

Usually, it doesn’t matter when you are using only a single RAM card. You can install the single RAM card in any slot you want. But, when it comes to two or four RAM cards, the scenario changes. If you have a dual-channel motherboard, you have to put the RAM card in particular pairs of RAM slots.

It’s recommended to use pairs like 1–2, 3–4, 5–6, 7–8, or 1–3, 2–4, 5–6, 7–8, or 1–5, 2–6, 3–7, 4–8 in the ram slots. You should do it if nothing is mentioned in the system manual. If you have a quad-channel board, you need to install each pair of RAM cards in precise ram slots. 

You can use these patterns if there is nothing written in the system manual: 1–2–3–4, 5–6–7–8, or 1–3–5–7, 2–4–6–8. The major significance of installing RAM cards in specific slots on the motherboard is to get the ultimate performance.

So, it’s recommended to check the manual of the motherboard to get the details on installing RAM slots. If there are no specific instructions, you should contact your motherboard manufacturer. Hopefully, they’ll get you enough information about which ram slots you should use to install the ram cards.

Are there any differences between these two slots?

Are there any differences between these two slots?

At a glance, you don’t see any difference between these two slots. But, the slots have some differences in performance. Your computer uses first and third ram slots are mainly utilized for single-channel ram installation. The second and fourth ram slots are utilized for the dual-channel ram installation support process.

However, the dual-channel ram slots are more modern technology. They provide a better data transfer rate than single-channel ram slots. As a result, their bus width is higher than the single-channel ram slots. We know that data bus width is the main factor for getting data about the system bandwidth.

So, we can easily understand that more data bus rate means more bandwidth. The process of bandwidth calculation is simple. You just have to multiply the bus rate by the DDR clock rate first. After that, you have to divide the result by 8.

A single channel ram slot can provide a 64-bit bus width. Hence, you have to calculate the bandwidth of a RAM that can provide 2400 MHz data speed. Ultimately, the result will be 19.2 Gbps. If we use the same ram for dual-channel slots, we will get a bandwidth of 38.4 GBps. It’s because dual-channel slots provide a 128-bit bus width.

When you use your computer for gaming or running any other heavy software, it will provide more FPS. As the dual-channel ram slots provide more speed, that means they have more benchmarks than single-channel ram slots.

Which ram slot should you use for the best performance?

Which ram slot should you use for the best performance?

When choosing the RAM slots, it is recommended to check the motherboard manual first. The manufacturers structured the motherboards to get the full performance from your computer. So, they can provide the best process to install the RAM to get proper performance.

But if it’s not mentioned in the manual, it is better to choose the dual-channel RAM slots. As they have more bus width, they provide more bandwidth in data transfer. In this circumstance, these ram slots can provide more frames per second.

The recent dual-channel RAM slots are more modern in technology. Most manufacturers now include them on their motherboards to improve performance. They provide more speed in data transfer. Therefore, you can feel the extra boost while gaming or running any heavy software.

What if you use the wrong ram slot?

What if you use the wrong ram slot?

At a glance or for regular usage, you won’t see a significant difference from using the wrong ram slots. But, when you are using your computer for heavy-duty purposes, you will face various issues.

The first issue is the lack of speed on the screen or FPS. In gaming, it is very important to have a proper FPS, or you won’t get proper enjoyment. And while running heavy-duty software, you can’t do your work perfectly with it.

Again, installing RAM in particular slots is important for the bus width of data transfer. More bus width means more bandwidth. If you install RAM cards in the incorrect slot, you will experience bandwidth issues.

The manufacturer makes a motherboard so that it can provide sufficient performance while running your PC. So, they recommended using RAM cards in particular slots to get the best performance. 

Which RAM slots to use for 2 sticks?

Which RAM slots to use for 2 sticks?

The RAM slots can be tagged by color or numbers on the motherboard. Before you try to install two sticks of RAM in the motherboard, you should look at the ram slot labels. If they are tagged by number, the numbers will be 0, 1, 2, 3 or 1, 2, 3, 4.

To get perfect performance from your RAM cards, you should install them in 1/3, 2/4, 0/2, or 1/3 RAM slots. If they are tagged with the color, you should install the RAM cards in a similar color for better performance. However, the manufacturer of the motherboard can suggest the perfect order of RAM slots for installing RAM cards.

As they manufactured the motherboard, they knew how to get proper performance out of it. So, if you want to get the proper performance, you should follow the order provided by the computer. 

Can you use both slots?

Can you use both slots?

Yes, you can use both slots for RAM cards. It’s highly beneficial to use both slots to get an extra boost of speed while running heavy-duty software. If you want to install 8 GB of RAM on your computer, the experts recommend using it in both RAM slots. You can do it by installing two 4GB RAM cards.

As a result, you will have more bandwidth while transferring data. Furthermore, you will have more FPS while playing games or performing different jobs on your computer. Installing two ram slots can also increase the speed of your computer while data transfer. It helps you can do your jobs faster and easier.

Here we attached a tutorial video about – does a ram slot matters. Watch that if you need more information:


RAM stores data for the computer. Therefore, it needs to be fast so that it can deliver more bandwidth while data transferring. You should take the necessary steps to get maximum performance from the RAM cards. And installing, in particular, RAM slots is one of them.

A question can be asked: Does it matter which RAM slots I use? Yes, installing RAM in particular slots boosts your PC performance. So, you can get more fps while playing a game or doing heavy-duty work on your computer. Nowadays, most motherboard manufacturers ask you to install RAM cards, in particular RAM slots. 

It’s recommended that when you are installing a big-sized ram card, you divide it into 2 or 4 slots. To get the maximum output from your computer, you should install the RAM cards in specific RAM slots.
