Memory Test

Memory Test stores a pattern of bytes in the computer's memory and reads it back, checking for errors. I have long used various versions of the memory test to diagnose unreliable hardware.

Memory 3

Memory 3 was an early memory test for the Z80.

Memtest

This is the Windows version of the memory test. It uses the same algorithm with the ability to test up to 2GBytes of memory! Unlike the PC's power-on self-test, this memory test runs continuously. It may be run overnight to check for problems in DRAMs and CPU caches.
