Perhaps the biggest issue that PC builders face is RAM incompatibility. You won’t believe how many machines I’ve seen get busted because of an incompatible RAM. Therefore, it is crucial to know what type of RAM is suitable for your motherboard and how much RAM it can handle.
The wrong type of RAM can lead to performance issues. At best, your computer may become slower. And worst case scenario, it could cause overheating.
So, how much RAM can your motherboard handle? Here’s all you need to know.
How much RAM can your motherboard handle? The maximum amount of RAM that motherboards can handle varies between motherboards.
It’s best to look up the motherboard documentation on the manufacturer’s official website. You can also use third-party apps like RAM scan tools.
How Much RAM Can My Motherboard Handle
RAM and motherboard incompatibility are significant problems when deciding on a suitable RAM for your computer. And even if you do find a RAM that’s compatible with your motherboard, performance issues are inevitable.
That’s why you should always be wary of how much RAM your motherboard can handle. So, the first step to determining the compatibility is to find out what type of RAM your motherboard can handle. This information will typically be available online. Then, find the right type of RAM that meets that criteria.
Types of RAM available
Here are the different types of RAMs that you can find today:
- Single Data Rate (SDR)
- Double Data Rate 2 Synchronous Dynamic RAM DDR2 SDRAM
- Double Data Rate 3 Synchronous Dynamic RAM DDR3 SDRAM
- Double Data Rate 4 Synchronous Dynamic RAM DDR4 SDRAM
- Double Data Rate 5 Synchronous Dynamic RAM DDR5 SDRAM
- Double Data Rate 6 Synchronous Dynamic RAM DDR6 SDRAM
Comparing these 6 generations, you’ll notice a trend: the specs are increased between each generation. So, for example, the RAM gets faster and consumes less energy. And with each succeeding RAM type, input lag is reduced significantly.
One important thing to note is that most motherboards are backward compatible. If a motherboard supports DDR4 SDRAM, it can support any generation before it. However, it cannot support DDR5 or DDR6 SDRAM.

Physically check your motherboard
If all of that is too complicated for you, there’s a more straightforward method: physically checking the motherboard. Physically inspecting the motherboard is vital to determine how much RAM your motherboard can handle.
The first step is to look for the documentation of the motherboard. An instruction manual will most likely be included with your motherboard purchase. But it might only include safety measures and installation instructions.
Search for the documentation online. This can either be official or unofficial. Look for forums and sites like Reddit where users share their experiences on the RAM limit.
Finally, if all else fails, you can look for the RAM capacity on the motherboard physically. Look at the RAM slots and see how many there are.
RAM sticks come in-memory variants, including 4 GB and 8 GB. Unfortunately, not every chip will allow you to insert 8 GB sticks. So, find out if your chip can multiply that by the number of slots.
For example, if your chip supports only 4 GB sticks and there are two slots, your motherboard can only handle 8 GB of RAM.
How Much RAM Can My Motherboard Handle: 32 bit vs 64 bit
How much RAM can my motherboard can handle is directly correlated with the number of bits the computer transfers in a single transaction.
If you’re on a Windows machine, there are only two choices: 32-bit and 64-bit. Here’s how to find out what system you have:
- Right-click on “My Computer” on your desktop. Or, open your File Explorer, find “This PC,” and right-click on it.
- Click on “Properties.”
- Here, you will see the type of Windows system you have under “System type.”
- Alliteratively, on Windows 7 machines, go to the Control Panel and click on System and Security.
- From there, click on System and look under “System type.”
If you have a 32-bit machine, you can only use up to 4 GBs of RAM. For 64-bit machines, you can use 128 GBs of RAM if you’re running Windows 10 Home. For Windows 10 Pro, you can have up to 2 TBs of RAM.
How Much RAM Can My Motherboard Handle: Based on Mac model
For Mac users, there’s an easy way to find out how much RAM your system supports. You need to know the Mac model.
There is no set amount of RAM that a group of models needs. Instead, the maximum RAM differs from model to model. That’s why it’s crucial to look up the documentation of your model to find out how much RAM it can handle.
However, there is a handier option. Your Mac device also tells you if your computer system needs more RAM. Here’s how to find out:
- Go to the Apple menu, then check About This Mac.
- Click on “Memory” and then click “Memory Upgrade Instructions.”
- The second option is to go to the Apple menu and click on About This Mac. Select “Support,” then click on “Hardware Support.”
How Much RAM Can My Motherboard Handle: on Linux
Finding out how much RAM your Linux system needs is quite challenging. For one thing, Linux itself is pretty hard to navigate if you’re used to the Windows or Mac interface.
Luckily, there’s a simple formula to figuring out how much RAM your Linux system can handle. Newer versions of Linux that use the 32-bit architecture can support a maximum of 64 GB of RAM. Older versions will support a maximum of 4 GB.
As for the 64-bit machines, they can support a lot more. On Intel systems, Linux can support up to 1 TB of RAM. And on AMD64 systems, it can support up to 256 TB.
So how do you find out how much RAM your system can handle? Here’s a simple method:
- Press CTRL+ALT+T. This will open the Terminal.
- In the Terminal, type “sudo apt install dmidecode.”
- Hit enter.
- This will install dmidecode.
- Once installed, click on the “sudo dmidecode –t 16”.
- Here, look for the “maximum capacity” field. This will show you the max RAM capacity the system can handle.
How Much RAM Can My Motherboard Handle: Find out with a RAM scanning tool
Still can’t figure out how much RAM you need? Don’t worry; there’s a more straightforward way to determine how much RAM your motherboard can handle.
There isn’t any specific RAM scan tool I recommend. Instead, you can find some from your RAM manufacturer’s website. For instance, if your RAM is made by Crucial, you can easily find their RAM scanning tool on their website. And the best part is, this tool is entirely free for Windows.
Should RAM Mhz Match the Motherboard?
When talking about RAM and motherboard compatibility, we forget one crucial aspect: speed. Does your RAM need to run at the same rate as your motherboard?
And the short answer is yes, and your RAM MHz must match your motherboard. If your RAM is too fast for the motherboard, it could easily lead to power loss and excessive heating. Too slow, and you may face performance issues.
But that’s not all.
If you have two RAM sticks that aren’t compatible, this can also create issues. Not only will you face overheating, but your motherboard will also only work at the speed of the slower RAM. And that’s if your computer doesn’t completely shut down.
What is RAM Overclocking?
The term “overclocking” gets thrown around everywhere. So, you might be wondering what it means. Overlocking means pushing your device past its limit.
This means running the RAM at a much higher speed than it usually does. This way, you get the highest performance out of the RAM. And this performance will even surpass the amount advertised.
However, as with everything, there is a cost. No, not a monetary value. But you will be sacrificing RAM health for performance. Too much overclocking can reduce the life of your RAM. And if overclocked incorrectly, you could risk damaging your computer permanently.
So, should you try it? On the one hand, it’s a suitable option for someone who wants to get the most out of their RAM. But on the other hand, it can severely affect future performance. So my advice is only to try overclocking the RAM if you know what you’re doing.
Should I Configure My Motherboard for Manual RAM Speed?
On some motherboards, you can configure your motherboard manually for maximum speed. This setting is usually present in the BIOS.
Some motherboards don’t allow this. This means they automatically select the best RAM speed depending on your requirements.
Here’s how you can manually configure your motherboard for RAM speed:
- Restart your system and tap Delete until you enter the BIOS. On some systems, the button may be different. Be sure to check the correct button for your system.
- In the BIOS, look for the “Overclock” setting.
- In the “Overclock” setting, look for the “Memory” setting.
- Find the setting labeled “DRAM Timing Mode.”
- Look for the “Advanced DRAM Configuration” in this setting and click on it.
- This should take you to a different screen to enter new values for the Memory Timings.
- The default timings here should be 9, 9, 9, 24 on most 1600 MHz systems. Of course, you can change it to whatever you want as long as you know what you’re doing.
- If your system has a higher speed of, say, 2133 MHz, you’ll need to increase the RAM speed to get the maximum performance.
- Once you do that, go back and search for the DRAM Voltage setting.
- This setting will most probably be set to Auto. Change it to any specific value that is suitable for your RAM. The voltage is usually 1.35 V, 1.50 V, or 1.65 V for DDR3 SDRAMs. But you should check the documentation of your RAM to find the correct voltage levels.
- Lastly, find the DRAM Frequency setting. Set the frequency to the desired value.
- Press F10 to save the changes you made to the BIOS and restart your machine.
- After the reboot, your settings should be applied. It’s good to download apps like CPU-Z and check the speed before and after changing it.
Stuck on a step? Here’s a video guide to help you out:
Now that you know how to configure your motherboard for manual RAM speed, the real question remains: should you do it? This is pretty much like overclocking, where you push the RAM past its standard specs to get the most out of it.
You may manually set the frequency, voltage, and speed. But be very careful as the wrong setting can quickly ruin your computer system.
