Can You Mix RAM Brands?

Most people don’t think about their computer’s RAM until it starts to slow down. At that point, it can be a confusing mess to try and figure out what type of RAM your computer uses, let alone try to find the right brand. In this blog post, we will answer the question: can you mix RAM brands? We will also provide tips for installing new RAM and maximizing your computer’s performance.

What is RAM and what does it do?

RAM is short for Random Access Memory. It is a type of computer memory that can be accessed randomly, meaning that any piece of data can be accessed without having to go through the previous pieces of data first. RAM is used to store information that the computer needs to access quickly, such as the currently open programs and files.

The amount of RAM in a computer affects how well it can multitask and how quickly it can access files. More RAM generally means that a computer can do more things at once without slowing down, and it can open files faster.

The different types of RAM

There are two main types of RAM: SRAM and DRAM. SRAM, or Static RAM, is faster and more expensive than DRAM, or Dynamic RAM. Most computer systems use a combination of both SRAM and DRAM.

SRAM is used for the computer’s cache, which is a small amount of memory that is used to store frequently accessed data. DRAM is used for the computer’s main memory, which is where all of the data for currently open programs are stored.

The type of RAM that your computer uses will be determined by the motherboard and the CPU. It is important to check what type of RAM your computer uses before buying new RAM, as they are not compatible with each other.

Most motherboards will have multiple slots for different types of RAM, so it is possible to upgrade your RAM by adding more of the same type or by adding a combination of different types.

How to identify which type of RAM your computer uses

The best way to figure out which type of RAM your computer uses is to check the documentation. The motherboard manual should list the supported types of RAM, and the CPU manual will list the speed and capacity of the cache.

If you can’t find the manuals, you can also look up your motherboard and CPU online to find this information. Once you know what type of RAM your computer uses, you can start shopping for new RAM.

Can you mix brands of RAM?

Yes, you can mix brands of RAM, as long as they are the same type. For example, if your computer uses DDR memory, you can use any brand of DDR memory. However, mixing different types of RAM (like DDR and SDRAM) will not work.

The best way to upgrade your RAM is to add more of the same type that you already have. If you need to add a different type of RAM, you will need to replace all of the existing RAM in your computer.

It is also important to note that mixing different sizes of RAM (like 1GB and 512MB sticks) can lead to performance issues. For best results, it is recommended to use sticks of the same size.

Installing new RAM is a relatively easy process, but there are a few things you need to keep in mind.

  1. First, make sure that you have the correct type and amount of RAM for your computer.
  2. Second, if you are adding additional RAM to an existing system, it is important to install the new RAM in the same order and configuration as the existing RAM.
  3. Third, when installing new RAM, it is important to ground yourself to prevent static electricity from damaging the RAM chips. To do this, you can touch a metal object or wear an anti-static wrist strap.
  4. Finally, make sure that the latches on the memory slots are fully seated to avoid damaging the RAM.

Once the new RAM is installed, you will need to configure it in the BIOS. The process for doing this varies depending on the motherboard, but typically you will need to enter the BIOS setup menu and change the memory configuration from “auto” to “manual.”

From there, you will need to specify the size, speed, and latency of the new RAM. Consult your motherboard manual or the manufacturer’s website for more information on how to do this.

Once you have configured the new RAM in the BIOS, save your changes and reboot your computer. The new RAM should now be recognized and working properly.

Factors that May Problematize the Combination of RAM Brands

To prevent harming your system, you need to take into account a number of possible concerns while installing new RAM. If you are upgrading an installation with RAM and are unable to match the manufacturer, at least make sure the following factors are the same.

It’s also important to keep in mind that how you use your computer will determine whether you experience the effects of any RAM mismatches. You are more likely to be conscious of the subpar performance of your RAM the more work you have to do.


Different ram modules need different voltages. If voltages are mixed, the more power-demanding RAM will get less power.

It will still function, but it may not perform at its best, and its stability could be compromised.

Memory: Single vs. Dual Channel

The memory configuration of the RAM slots may affect your performance depending on your needs.

Memory comes in single and multi-channel varieties. They function in various ways and could go unnoticed by most users. When the RAM is mixed, some RAM may operate in a single channel as opposed to a dual channel.

Users who are only browsing or playing games are unlikely to notice an issue, but for more demanding workloads like video editing or 3D rendering, dual-channel RAM may increase speed by up to 20%.

Storage Volume

Memory settings may be impacted by mismatched RAM stick sizes. Asynchronous operation results from pairing two RAM modules, one bigger and one smaller.

This is referred to as Flex Mode.

It may result in only pairing half of the larger RAM module with the smaller RAM. The single-channel mode will be used for the remaining RAM.

The degree to which this imbalance is apparent depends on the workload.


The efficiency of your memory may be considerably impacted by the speed of various RAM kits.

There will still be some problems even if you set RAM to operate at the speed of the slowest RAM module.

Memory speed is impacted by frequency and latency. The same latency is required for RAM sticks with various frequencies to function together.

If you’re feeling mathematical, you may use the following method to determine the latency of your RAM stick instead of a RAM Latency calculator.

The delay in nanoseconds is calculated by reciprocally dividing the clock frequency (cycles) by two.

Due to speed variances, if your RAM sticks fill more than three or four DIMM slots, problems are likely to arise.

How much RAM should you upgrade to

The amount of RAM that you should upgrade depends on what you plan to use your computer for. If you just want to improve overall system performance, adding more RAM will help.

If you are a power user or gamer, you may need to upgrade to as much as 32GB of RAM. However, most users will be fine with between 1-16GB of RAM.

When upgrading your RAM, it is important to buy the same type that is already on your computer. For example, if your computer uses DDR memory, you should buy DDR memory.

You can mix and match different brands of RAM, as long as they are the same type.

A simple reference on how much RAM you would need for certain jobs is provided below:

  • 4GB – 4GB is plenty if all you want to do is leisurely surf the internet, create documents, or send emails. But if you wish to go above that, you’ll start to have performance problems.
  • 8GB – If you want to multitask and have many apps open at once, this is an excellent size. The majority of films and games will work without a problem, but at the maximum visual settings, your PC can have trouble keeping up.
  • 16GB – The ideal place. 16GB of RAM is the ideal amount to use if you want reliable performance all around. Whether it’s gaming or intensive multitasking, you’ll be able to perform the majority of what you want to do and your RAM will hold up. For many people, 16GB of RAM may be a huge improvement over 8GB of RAM.

First, make sure that you have configured the RAM properly in the BIOS. Incorrectly configuring the RAM can lead to stability issues and reduced performance.

Second, keep your computer’s BIOS and drivers up to date. Outdated BIOS and drivers can cause compatibility issues with new hardware.

Finally, if you are a power user or gamer, you may want to consider overclocking your RAM. Overclocking can lead to increased stability and performance but it is also more likely to cause problems. If you do decide to overclock your RAM, be sure to do your research and start with a small overclock. Too much of an overclock can damage your hardware.

Can you mix different-sized RAM modules?

As long as the frequency, brand, latency, and ranks of your RAM modules are the same, mixing memory sizes shouldn’t be a problem.

Can DDR3 and DDR4 RAM be used together?

No, RAM Modules from different generations can’t be mixed. Physically, DDR3 and DDR4 RAM can’t work together.

Can you mix different RAM Frequencies?

Mixing RAM Modules with different speeds is possible, but it could cause problems. All RAM Modules have to run at the same speed, so they’ll try to run at the speed with the fewest differences.

But because different types of RAM modules support different latencies at different frequencies, they might not be able to sync properly, which could make your system unstable or stop it from POSTing or booting.

Can I use all of my motherboard’s RAM slots?

Your motherboard will ultimately determine the best configuration, however, having an equal number of identical sticks is nearly always preferable.

If your motherboard has four slots, it is best to leave two of them unoccupied.

Use all four slots if you require a lot of rams since performance problems might arise if you leave one open.


In conclusion, it is usually advisable to use a single RAM kit if you want to upgrade the memory in your computer.

It is understood that this would not always fit your present demands and the allocated money.

Make sure to obtain RAM requirements that are future-proof if you’re intending to create a new computer so that upgrading in the future will be simple.

You may always buy more RAM and experiment with adding it to your PC until you can replace the older memory if your PC already has a RAM kit that is slower than you’d like.

Keep in mind that your chances of finding the best compatibility will increase the more variables you can remove from the equation.
