When installing new memory, which is an important factor to check?

System compatibility
Type of operating system
Power supply rating
Graphic card specifications

The correct answer is: System compatibility

When installing new memory, checking for system compatibility is crucial. This involves ensuring that the memory module you intend to install is compatible with the motherboard and the existing system architecture. Factors that define compatibility include the type of RAM (such as DDR3, DDR4, or DDR5), the maximum capacity the motherboard can handle, and the speed ratings supported by the system. If the memory is not compatible, it may not function at all, or it can cause instability and crashes after installation. In contrast, while the type of operating system, power supply rating, and graphic card specifications are important considerations when upgrading or building a PC, they do not directly affect the installation of memory. The operating system is more related to software compatibility and performance. The power supply rating is vital for ensuring that all components receive adequate power, but it does not influence the memory itself. Similarly, graphic card specifications do not impact how memory functions or the installation process. Thus, focusing on system compatibility is essential for a successful memory upgrade.
