To upgrade all system memory with the fastest available options, what is your best course of action?

Choose RAM with the highest MHz rating
Choose compatible memory supported by the motherboard
Buy the latest RAM technology available
Match memory speeds with the slowest module

The correct answer is: Choose compatible memory supported by the motherboard

Selecting compatible memory supported by the motherboard is crucial when upgrading system memory. Each motherboard has specific requirements and limitations when it comes to memory types, such as DDR (e.g., DDR3, DDR4, DDR5), maximum supported RAM capacity, and memory speed (measured in MHz). Even if you opt for RAM with a high MHz rating or the latest technology, it won't perform optimally if it isn't supported by the motherboard. For example, installing DDR4 RAM into a motherboard that only supports DDR3 will not work, as the physical notches and electrical signaling will differ. Therefore, ensuring compatibility will safeguard against functional issues and allow the system to utilize the RAM effectively, potentially activating any performance benefits associated with faster RAM, provided the speed aligns with the motherboard's specifications. Choosing RAM solely based on speed or technology without first checking compatibility could lead to wasted resources or a non-functional upgrade.
