Running the MemTest86

MemTest86 is used to find the memory errors. MemTest86 uses advanced algorithms that are highly effective at detecting difficult memory errors. MemTest86 has the capability to test all available memory.

When MemTest86 starts it displays details about the system configuration and then begins testing. MemTest86 executes a repeating cycle of tests. Testing will continue to run until the program execution is interrupted by pressing <ESC>.

MemTest86 executes a series of numbered test sections to check for errors. The time required for a complete pass of MemTest86 will vary depending on CPU speed, memory speed, and memory size.

If memory errors are detected they will be displayed on the lower half of the screen. The default error reporting mode will display a detailed summary of all errors.

Boot the system using the DOS-Based MemTest86 Utility (Dell 9G-13G servers) option.
