MemTest86 is a standalone memory testing tool designed to detect faults in a computer's RAM. It operates independently of the operating system by booting from a USB flash drive, allowing it to thoroughly test memory for errors using a suite of algorithms and test patterns. The software is widely used by system builders, PC repair technicians, overclockers, and manufacturers to identify faulty RAM, which is often a source of random system crashes, data corruption, and unexplained behavior. MemTest86 supports both x86 and ARM architectures and is compatible with modern UEFI firmware. It is available in both free and paid Pro versions, with the latter offering additional features.
