Explanation
Correct answer is A. Purchase the same architecture of RAM.
When upgrading a laptop's RAM, it is crucial to ensure that the architecture (such as DDR3, DDR4, or DDR5) matches the existing memory module and the laptop's motherboard specifications. Different types of RAM (e.g., DDR3 vs. DDR4) are not physically or electrically compatible with each other.
Explanation of other options:
-
Configure the laptop's BIOS settings for the RAM upgrade: While some BIOS settings may need adjusting, most modern laptops automatically recognize new RAM without manual configuration in the BIOS.
-
Purchase RAM with the same column address strobe latency: While CAS latency can affect performance, matching the architecture (DDR version) is more critical. CAS latency is a secondary consideration, especially for typical users.
-
Purchase the same brand of RAM: It is not necessary to buy the same brand of RAM, as long as the new RAM is compatible with the laptop's architecture and specifications.
