How do I know how much RAM my motherboard supports?

How to know how much RAM memory my motherboard supports can save us more than one disappointment when deciding to expand our hardware without buying the complete pack. We are talking about motherboard, processor (CPU), and RAM memory. Every motherboard has a limit of installable RAM, and also a limit on the frequency at which this RAM is capable of working. In this article, we will try to find out the maximum figures that our motherboard supports.

And the truth is that knowing how much memory the motherboard supports is quite simple, as long as we know the model of the motherboard we have, which is almost always the most problematic thing to find out. So let’s go little by little and try to make all possible considerations.

Why we are interested in installing more RAM

Do we really need more RAM than we have? This is the first question we must ask ourselves. RAM memory is one of the main hardware components of our equipment. Thanks to it, the operating system can load the programs that are being used in it, its processes, and the instructions that will be executed by the processor.

The more RAM memory, the greater the number of programs and the more workload we can carry out on our PC. Of course, we would have to take into account the power of our processor, but hey, that’s another question than this. In any case, once we exceed the memory used by the system plus programs we will not obtain better performance, that is, if we have 8 GB and we still have space left over, no matter how many GB we install, our PC will not go faster. Currently, if we have Windows 10 installed on our PC, and in its 64-bit version (we hope so), it is always recommended to have more than 4 GB of RAM. Special in this 64-bit version, it is better to have at least 8 GB, since the system itself at half load usually uses quite a lot of space.

What does the maximum memory that we can install depend on?

Each motherboard has a limit of RAM that can be installed. And not only in quantity, but also in the type of memory, for example, if it is DDR3, DDR4, or any other DDR. But we will also have a limit in terms of memory frequency, that is, if for example we install 4000 MHz RAM and the board supports only 2400 MHz, then our memory will not work at maximum speed. In this way, the factors that influence the amount, type, and frequency of memory that we can install will be the following:

Motherboard manufacturer and model : 

there are many motherboard manufacturers on the market, and each of them creates a product according to performance and price.

The processor :

 the RAM memory communicates directly with the processor. It is true that the chipset of the motherboard will determine which processor to install, but in turn, the processor will determine how much RAM to install since it is the one that addresses the available memory cells. There are two manufacturers of processors on the market: Intel and AMD. Each of them has several generations of processors, and with different powers. So we will also need to know in detail what processors we have to know how much memory we can install on our motherboard.

The chipset:

 The chipset limits not the amount of memory, but the speed at which it can work through JEDEC profiles . Although this is better treated in a separate article.

In the specifications of the processors, a RAM memory speed limit is also imposed. This limit does not imply that we cannot install faster memories , since this “official” limit is not an obstacle to obtaining better performance from a system with a RAM of, for example, 4000 MHz, even though the processor only supports 2666 Mhz.

Generic capabilities by platform and chipset

This information cannot be fulfilled to the letter, because depending on the DIMM slots that each board has, it will admit more or less RAM memory. In any case, we will be able to know the maximum amount of memory depending on the socket that we have installed on our PC.

In all cases, they will be DDR4 RAM memories:

Intel platform

  1. LGA 1151 socket : (6th and 7th generation): 64 GB (4 DIMM slots)
  2. LGA 1151 socket : (8th and 9th generation): 64 GB (4 DIMM slots)
  3. Socket LGA 2066: 128 GB (8 slots DIMM)
  4. Socket LGA 2011 V3: 128 GB (8 slots DIMM)

Plataforma AMD

  • Socket AM4: 64 GB (8 slots DIMM)
  • Socket TR4: 128 GB (4 slots DIMM)

How to know what motherboard I have (quick option)

Well, the first thing we will have to do is find out what motherboard we have installed on our computer. If in your case you already know the brand and model, then it will not be necessary for you to follow this point.

If this is not your case, you will need to find out what model of motherboard you have , so you can also know the chipset you have to install and, consequently, what processor it supports and how much memory you can install. Did you catch it?

At this point, we will have two options. The first is to dust off the box of our motherboard (if we buy the PC by parts), there somewhere they will be able to see the motherboard model we have. Hopefully, we will also have the user manual in which the issue of RAM memory will come. The second option is to install a program that tells us what hardware we have on our PC.

We are going to opt for this second option. Well, the first program that we are going to install is one of the CCleaner family, so don’t panic! We are not going to do PC cleaning. This program is called Piriform Speccy. We know that you are lazy to look for it, so click here to download and install it. In any case, there are many others available on the Internet, for example, Aida 64, Everest, HWiNFO, CPU-Z, etc.

On the first installation screen, disable the option to install CCleaner. Once installed, we will open it and it will automatically collect all the information about our equipment. We are going to go to the “ Summary ” or “ Motherboard ” section to know our motherboard.

We will have extremely important information on this screen. In “ manufacturer ” and “ model ” we will have the brand and model of the board, this is what we want. But we will also be able to find out what kind of CPU chipset you have, the “ Southbridge model ” chipset, BIOS, etc.

We could also go to the “RAM” section to find out how many slots our board has.

The second program that we could use is CPU-Z, which is capable of giving us the name of our board and some other characteristics. It is another very simple program that gives us a lot of information.In our example we have the following board: Asus B150 Pro Gaming AURA and we already know in advance that its capacity is 64 GB. According to socket LGA 1151 and 4 memory slots.

What processor do I have (for being completists)

We already know the name of our motherboard, we could already know how much RAM it supports, but we are going to do things right, and we are also going to know how much our CPU supports. If we do not plan to buy a new processor, this information could be important.

We use this same Speccy software to find out what our CPU is. Let’s go to the “ CPU ” section. We will thus know its full name, number of cores, technology threads, and the generation to which it belongs. We are interested in your name. We could also have used CPU-Z again which will also give us all this and more information. In fact, it specializes in this type of information.

How do I know how much RAM my motherboard supports?

The time has come, we already have everything , name of the plate and name of the processor. Now the wisest thing will be to make use of our friend Internet . It is not about us saying how much memory all CPUs or all boards support, but about learning to do it yourself and apply it to any case.

Maximum motherboard memory

Let’s start with our motherboard. Let’s go to the official website of the motherboard manufacturer. Or directly put all the name in San-Google. Searching the manufacturer’s pages can also do this job.We will look at your specifications. The list of specifications is practically identical in all manufacturers. We will identify this information in the memory section .

We then see that our motherboard has 4 DIMM slots that support up to 64 GB of DDR4 RAM at a speed of 2133 MHz and in Dual Channel. We already know something new, on this board we will only reach a RAM speed of 2133 MHz.

Maximum processor memory

Now we are going to see the information that the manufacturer gives us about the memory that the processor supports. So we go to Intel or AMD and look for our CPU.

There we have the specifications of our 6th generation i5-6500. It supports a total of 64 GB of DDR4 2133 MHz RAM and also DRR3L (for laptops).For AMD, you may only find the supported memory frequency and version. So for maximum capacity, we will listen to the motherboard itself .

Conclusion on how to know how much RAM my motherboard supports

We believe that listing here in a generic way chipsets and boards with the memory they support makes little sense, and that is why we have provided useful information so that everyone who knows their hardware can obtain information about it with the best tool: Internet.

Did you get it all right? If you have any questions, or any problems getting the information you need, leave us a comment. If you prefer, you can enter our Hardware Forum and open a topic with your questions so that we can all help each other. Don’t hesitate to check how much RAM your PC has .
