Can I use 8GB RAM together with 4GB RAM? (2024)

Yes, it is possible to use 8GB RAM together with 4GB RAM in a laptop, provided that your laptop has the necessary slots and supports mixed RAM configurations. This is known as a mixed or dual-channel configuration.

When using different RAM sizes, the operating system and the laptop’s memory controller will work in dual-channel mode for the matching portions of the RAM (e.g., 4GB+4GB) and in single-channel mode for the unmatched portion (e.g., 4GB only). In dual-channel mode, memory access is faster and more efficient, which can improve overall system performance.

However, it’s important to note that there may be some limitations and considerations:

Compatibility: The RAM modules should be compatible in terms of their type (e.g., DDR3, DDR4), speed, and voltage. It is recommended to use RAM modules from the same manufacturer and of the same specifications for the best compatibility.
Clock Speed: When different RAM modules are used together, they will operate at the speed of the slowest module. So, if the 8GB and 4GB modules have different clock speeds, they will both run at the lower speed.
Capacity: Keep in mind that the total amount of usable RAM will be limited by the lowest capacity module. In this case, the laptop will utilize 4GB of RAM in single-channel mode and 4GB in dual-channel mode, totaling 8GB.
Stability: Mixing different RAM modules can sometimes lead to stability issues, such as system crashes or compatibility problems. While it can work in most cases, it’s not guaranteed to be problem-free.

If you’re considering upgrading your laptop’s RAM, it’s generally recommended to install matching modules for optimal performance. However, if you already have an 8GB module and want to add a 4GB module, you can give it a try and see if it works well. Just make sure to check the compatibility and specifications of both modules before attempting the configuration.
