What is MemTest86?
MemTest86 is the original, free, standalone memory testing software for x86 and ARM computers. MemTest86 boots from a USB flash drive and tests the memory in your computer for errors using a comprehensive set of algorithms and test patterns.
Why should you test your RAM?
Unreliable memory can cause a variety of problems. Corrupted data, crashes and strange behavior.
Low memory is one of the most frustrating computer problems because the symptoms are often random and difficult to pinpoint. MemTest86 can help diagnose faulty RAM (or rule it out as the cause of system instability). Therefore, it is widely used by system designers, PC repair shops, overlockers and PC manufacturers.
