Which tools are commonly used for testing RAM stability and performance?

Memtest86 and Windows Memory Diagnostic are well-established tools specifically designed to test the stability and performance of RAM. Memtest86, known for its in-depth testing capabilities, operates outside the operating system and comprehensively checks memory for errors through various test patterns. If any issues are detected, it can indicate potential problems with the RAM modules, helping users identify faulty hardware before it leads to more significant system instability.

Windows Memory Diagnostic is another tool that runs tests on the memory when the system is rebooted. It checks for memory-related issues by performing a series of stress tests. Both tools can efficiently help users diagnose whether their RAM is functioning correctly, thus ensuring the overall stability of a system.

While other options listed may provide information related to system performance or hardware monitoring, they do not specifically focus on memory testing in the same dedicated way that Memtest86 and Windows Memory Diagnostic do. This specificity is what makes B the correct choice for highlighting tools meant for RAM stability and performance testing.
