Can You Have 2 8gb And 2 16gb Ram?

RAM, or Random Access Memory, is a crucial component in any computer or laptop. It provides temporary storage for data and instructions that the processor requires to perform tasks. The amount of RAM in a system can significantly impact its overall performance. In recent years, it has become a common question among computer users whether they can have 2 8GB and 2 16GB RAM. In this article, we will explore the possibilities and limitations of mixing RAM capacities.

Traditionally, it was considered best practice to install identical RAM modules in a system. This method ensures compatibility and prevents any potential issues arising from using different speeds and timings. However, with advancements in technology, it is now possible to mix RAM capacities. Most modern motherboards support different sizes and speeds, allowing users to add or replace RAM modules as needed. In the following sections, we will take a closer look at the advantages and disadvantages of mixing 8GB and 16GB RAM modules in a single system.

Can You Have 2 8GB and 2 16GB RAM?

Yes, you can have 2 8GB and 2 16GB RAM sticks in your computer, but it is important to follow compatibility guidelines to ensure that the system can handle the different sizes:

– Your computer must have multiple RAM slots available to accommodate 4 RAM sticks.
– The RAM speeds, timings, and voltage must match across all sticks to prevent instability or crashes.
– It’s recommended to install RAM sticks in pairs (e.g. 2 x 8GB and 2 x 16GB) to take advantage of dual-channel memory architecture, which can enhance system performance.
– Your motherboard’s maximum supported RAM capacity must also be taken into consideration to ensure that it can handle the combined memory.

Overall, it is possible to mix different sizes of RAM sticks, but compatibility must be carefully considered when doing so to avoid potential issues.


1. Can I mix 8GB and 16GB RAM?
Answer: Yes, you can mix 8GB and 16GB RAM as long as they are of the same type (DDR3, DDR4, etc.), speed, and voltage.

2. Is it better to have all RAM slots occupied?
Answer: It depends on the maximum capacity supported by your motherboard. If your motherboard supports a maximum of 32GB of RAM and you already have 2x8GB and 2x16GB installed, the extra 8GB of RAM will not be utilized.

3. Can mixing RAM sizes cause issues or reduce performance?
Answer: Mixing RAM sizes could cause compatibility issues and reduce performance if the RAM modules have different speeds or latency. It’s best to use RAM modules with similar specifications to avoid potential issues.

4. What is the maximum amount of RAM that can be installed on a motherboard?
Answer: The maximum amount of RAM that can be installed on a motherboard varies depending on the motherboard’s specifications. Most consumer motherboards can support up to 64GB of RAM, while some workstation boards can support up to 256GB.

5. Do I need to configure anything in BIOS when adding new RAM?
Answer: It’s a good idea to check the BIOS settings after installing new RAM to ensure that it is recognized and configured properly. Some motherboards will automatically configure the new RAM, while others may require manual configuration.


In summary, it is possible to have 2 8GB and 2 16GB RAM in your computer. However, it is important to note that this configuration may not be the most efficient or cost-effective option. It is always advisable to consult with a professional before making any changes to your computer’s hardware. Ultimately, the RAM configuration you choose should be dependent on your computer’s motherboard compatibility and your specific needs for performance.
