PassMark MemTest86 Pro – Detect Faulty RAM and Improve Reliability

PassMark MemTest86 Pro Overview

PassMark MemTest86 Pro Memory Diagnostic Standard. Loads from a USB drive to check your computer’s RAM for faults. Uses algorithms that have been developed for over 20 years. MemTest86 is the original professional standalone memory testing software for x86 and ARM computers. MemTest86 boots from a USB stick and tests your computer’s RAM for faults using a range of complex algorithms and test patterns. Bad RAM can cause a variety of problems. Corrupted data, crashes, and unexplained behavior.
Bad RAM is one of the most frustrating computer problems because the symptoms are often random and difficult to pinpoint. MemTest86 can help diagnose bad RAM (or rule it out as a cause of system instability), which is why it’s often used by system builders, PC repair shops, overclockers, and PC manufacturers.
