A situation may be encountered where the health of a system's memory may need to be checked. If a fault in physical memory is suspected, the memory can be tested using a software utility called memtest86+ (often just referred to as memtest ).

The memtest86+ will run a series of tests of the memory.

Note: For systems with large amounts of memory, these tests can take a considerable amount of time to run to completion. As the system being tested needs to be booted into the memtest86+ environment while the tests are being run, the operating system on the system will not be available, making the system effectively down while booted into the memtest86+ environment.
