Unreliable RAM can cause a multitude of problems. Corrupted data, crashes and unexplained behaviour. Bad RAM is one of the most frustrating computer problems to have as symptoms are often random and hard to pin down. MemTest86 can help diagnose faulty RAM (or rule it out as a cause of system instability). As such it is often used by system builders, PC repair stores, overclockers & PC manufacturers.
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. This covers both 32bit and 64bit machines. (So there is no need for a future product called MemTest64).
Since MemTest86 v5, the software is offered as a Free edition, or as a paid for Pro and Site edition. The Pro edition offers a number of additional features such as customizable reports & automation via a configuration file. The Site edition includes all features in the Pro Edition but also supports scalable deployment of MemTest86 across LAN via PXE boot.
- Added check for whether the number of errors exceed a maximum error count. If so, the tests are aborted. This can be configured via the configuration file parameter MAXERRCOUNT. By default the value is 10000
- Added support for Russian language
- Added new configuration file parameter EXITMODE for specifying whether to shutdown or reboot the system on exit
- Added support for reporting to Management Console (
) via XML messages over TFTP (Site Edition only). The status of MemTest86 is periodically reported to the management console
- Added new configuration file parameter TFTPSERVERIP for specifying a different TFTP server IP address for sending report files and reporting to the management console (Site Edition only)
- Added workaround for retrieving configuration files from TFTP servers that don't support the 'get file size' TFTP command (Site Edition only)
- Added workaround for Serva bug when overwriting a file on the TFTP server (Site Edition only)
- Fixed bug with generated HTML/XML files that require character escaping
- Added workaround when firmware EFI_GET_TIME function fails to retrieve the time correctly. A warning is also written to the log file
- Added new flag DISABLE_CONCTRL to blacklist for console control workarounds for older firmware
- Fixed 'ALL' BIOS versions not being parsed properly in blacklist
- Updated blacklist.cfg file with additional baseboards with known issues
- Added more robust detection of CPU hyperthreads
- Added ECC detection support for Intel Skylake-SP chipsets
- Added ECC detection/injection support for AMD Ryzen chipsets
- Added warning message to log file when ECC injection is locked on Atom C2000 chipsets
- Fixed bug with ECC error reporting on Intel Xeon E3 chipsets
- Fixed CPU temperature not being shown for Intel Apollo Lake, Skylake-X and Broadwell-E chipsets
- Added preliminary support for retrieving CPU info for Intel Cannon Lake/Knights Mill chipsets
- Fixed bug with retrieving the number of boosted P-states in AMD chipsets
- Fixed CPU temperature not being read properly on AMD 15h (model >= 40h) chipsets
