Basically, manufacturers do not encourage people to use 2 different RAM sticks on the same motherboard. In some cases, this is still possible, but your computer’s performance will be significantly affected.
First, you need to make sure that your two RAM sticks, although different in brand and capacity, are still the same type of RAM. Can be all DDR3, DDR4 or DDR5. If you plug 2 RAM sticks of different types onto the same motherboard, your computer will not work.
When you plug in 2 RAM sticks of different capacities, for example a 4GB stick and a 16GB stick on the same motherboard, the system will work, but some problems and limitations may occur:
1. Amount of RAM used: The system will use the total RAM capacity of the smaller stick (in this case 4GB). The 16GB RAM bar will not be fully utilized. This means that you won’t be able to use the full performance of the 16GB stick.
2. Performance: The system will operate stably, but data access speed may decrease because the 4GB RAM stick can operate at a lower speed than the 16GB stick. This can lead to limited overall system performance.
3. Compatibility: Compatibility issues can occur, especially when different RAM sticks are not compatible with each other or the motherboard. Likely to cause errors or instability in the system.
In general, you can use two RAM sticks of different capacities on the same motherboard, but for optimal performance and stability, it is recommended to use RAM sticks of the same capacity and specifications. If you cannot get the same capacity, you should consider replacing the smaller RAM stick with a larger capacity RAM stick to take full advantage of the system’s capabilities.
