Since then, there have been more than a dozen new versions released. However, some of the testing algorithms used have been under development since 1981 and were previously implemented on Dec PDP-11, VAX-11/780 and Cray XMP (an old super computer) architectures. Supported OS: Windows 11, Windows 10, Windows 8.MemTest86 (without the plus) was originally developed by Chris Brady (BradyTech Inc) with a first release in 1994.Technical Details and System Requirements Dual booting - Will boot to V4 in BIOS and V7 in UEFI from a single flash drive.Network (PXE) boot - Scalable, disk-less provisioning from a single PXE server.Self-booting off USB without needing DOS, Linux, or Windows.Foreign language support (Chinese, German & 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.System builders, PC repair stores, overclockers & PC manufacturers often use it. MemTest86 can help diagnose faulty RAM (or rule it out as a cause of system instability).

Insufficient RAM is one of the most frustrating computer problems, as symptoms are often random and hard to pin down. Unreliable RAM can cause many problems: corrupted data, crashes, and unexplained behavior. (So there is no need for a future product called MemTest64). This covers both 32-bit and 64-bit machines.

The number 86, following the MemTest part of the name, refers to the original x86 CPU instruction set that all of today's PCs use. 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. Free Download PassMark MemTest86 Pro for Windows is the original, free, stand-alone memory testing software for x86 computers.
