Post Description

MEMTEST86 is the original, free, stand-alone memory testing software for x86 and ARM computers.

BOOTS from USB flash drives to test the RAM in your computer for faults.

UTILIZING algorithms that have been in development for over 20 years.

Industry standard since 1994.

Features: PassMark MemTest86 supports all current technologies:

13 different RAM testing algorithms - including row hammer fault detection*
All RAM types supported (DDR2, DDR3, DDR4, DDR5, SODIMM, XMP, ECC)
Self-booting off USB or Network (PXE)* boot, without needing DOS, Linux nor Windows
Optimized for UEFI-based x86/ARM systems
Native 64-bit code (since version 5)
ECC error detection & injection*
Secure Boot verified – Code signed by Microsoft
Graphical interface with mouse input
Save logs and create customizable HTML reports
Full test automation via configuration file
Support for memory blacklisting in Windows (badmemorylist) and Linux (BADRAM)
Multi-language support (Chinese, German, Russian, Spanish & more)

Version 10.5 (Build 1000) 19/June/2023 New Features:

Added preliminary support for Ryzen Zen 4 DDR5 chip decoding
Revised criteria for determining the final result of a memory test
PASS – All configured tests were completed without any errors detected
FAIL – All configured tests were completed with at least one error was detected or MAXERRCOUNT is exceeded at any point of the test
INCOMPLETE PASS – At least one of the configured tests was not completed but no errors were detected
INCOMPLETE FAIL –At least one of the configured tests was not completed and at least one error was detected
Revised criteria for determining the test result of individual modules
PASS – All configured tests were completed and no errors were detected on the module without any undecoded errors
FAIL – All configured tests were completed with at least one error detected on the module
INCOMPLETE PASS – At least one of the configured tests was not completed but no errors were detected on the module without any undecoded errors
INCOMPLETE FAIL –At least one of the configured tests was not completed and at least one error was detected on the module
UNKNOWN – No errors were detected on the module but there was at least one undecoded error
Fixes/Enhancements
Added preliminary implementation of ECC injection for Ryzen Zen 4 chipsets
Fixed module decoding for DDR4 x16 modules
Display ECC error count in message after completing a test pass
Fixed incorrect calculation of DDR5 SPD memory bandwidth
Added additional columns to module result table in HTML report
Removed "Go back to menu" option from the test menu
Included '# Tests Completed' in HTML report
