MemTest86 can help diagnose faulty RAM (or rule it out as a cause of system instability). Bad RAM is one of the most frustrating computer problems to have as symptoms are often random and hard to pin down. Corrupted data, crashes and unexplained behaviour.

Unreliable RAM can cause a multitude of problems. Network (PXE) boot – Scalable, disk-less provisioning from a single PXE server.Self booting off USB, without needing DOS, Linux nor Windows.

Foreign language support (Chinese, German and more).Graphical interface, mouse support and logging of results to disk.Secure boot – With MemTest86 being code signed by Microsoft.ECC RAM – support for error-correcting code RAM.64bit – From version 5, MemTest86 is native 64bit code.UEFI – The new graphical standard for BIOS.Using the information about the chipset you can enhance these tests – particularly in an overclocked system. Memtest86 writes a series of test patterns to every memory address, reads back the data written, and compares it for errors. It tries to verify that the RAM will accept and correctly retain arbitrary patterns of data written to it. MemTest86 boots from a USB flash drive and tests the RAM in your computer for faults using a series of comprehensive algorithms and test patterns. Memtest86 by PassMark is a comprehensive, free, stand alone memory diagnostic software It is designed to stress test an x86 compatible computer’s random access memory (RAM) for errors.
