MemTest86 is a bootable program that checks computer RAM for faults using memory test algorithms and patterns. It runs from a USB drive without an operating system, although Windows, Linux, or an Intel-based Mac can be used to create that drive. Version 11.7 requires UEFI firmware and x86 or ARM64 hardware; it does not support Apple Silicon M-series Macs. The product lists 14 test algorithms, including SIMD, Row Hammer, and DMA tests, and memory support for DDR2, DDR3, LPDDR4, LPDDR5(x), ECC, CDIMM, and CAMM2. It can generate customizable HTML reports and, on supported configurations, decode an error address to identify a failed DIMM or chip. The Free Edition supports up to 16 CPU cores; Pro supports up to 512 and adds full test automation and custom tests through a configuration file. Site Edition adds LAN deployment through PXE boot and PassMark Management Console integration and reporting. The binaries support Secure Boot and are signed by Microsoft. The maker identifies system builders, PC repair stores, overclockers, and PC manufacturers as users diagnosing RAM faults or ruling them out as a cause of instability.
Who it is for
MemTest86 suits system builders, PC repair stores, overclockers, and PC manufacturers diagnosing RAM faults or investigating system instability. It also suits users who need a bootable memory test independent of an installed operating system.
