How to report problems
Either make a post here in the forum, or send us an email at the address listed on our contact page. When reporting an error please provide as much details as possible. If you are running on a USB drive, there should be a log file that has been generated in the EFI/BOOT directory called MemTest86.log. Sending us this will be of great help. Additionally a photograph of the problem would also be useful if possible/applicable.

New Features
- Support UEFI-based ARM systems (arm64/aarch64), including memory test algorithms ported to ARM64 and optimized using hand-written assembly code. Special thanks to Simula eX³ project (ex3.simula.no) for providing high-end ARM64 systems for testing.
- Added BADRAM & badmemorylist formatted strings and instructions in the exported HTML report to mask defective memory addresses (Pro only)
- Revamped RAM SPD screen in the Main Menu with graphical view of all RAM slots
- Added preliminary support for DIMM temperature reporting (when supported by DIMM)
- Added option to change save location of logs/reports to another disk volume (file system)
- Added prompt on various exit options (shutdown, reboot, exit to BIOS) on application exit.
- Added keyboard shortcut (F12) to save screenshot to file within the Main Menu
- Support for saving test results to a byte-packed, binary file for storage-limited systems
- Support for passing configuration parameters via command line arguments
- Added new config file parameter, 'EXACTSPDSIZE', to specify the total capacity of all detected SPD to match before allowing tests to begin
- Added new config file parameter, 'MEMREMMB', for specifying the minimum amount of memory to leave unallocated during testing
- Added new config file parameter, 'MINMEMRANGEMB', for specifying the minimum size of memory ranges that shall be allocated for testing
- Added new config file parameter, 'AUTOREPORTFMT', for specifying report format of auto-saved reports
- Added new config file parameter, 'PMPDISABLE', to disable TFTP uploading of XML messages for Management Console integration
- Added new config file parameter, 'RTCSYNC', to sync real-time clock with PXE server (via a periodically updated 'CurrentTime.txt' served by the PXE server)
- Added new config file parameter, 'VERBOSITY', for specifying the verbosity level of the debug output
- Added new config file parameter, 'TPL', to specify the UEFI task priority level of the MemTest86 application
Fixes/Enhancements
- Support for per-baseboard configuration file via baseboard-prefixed filename (eg. "Surface Pro-mt86.cfg")
- Optimized/removed stale 32-bit code in memory tests
- Improved test coverage by alternating between ascending/descending assignment order of CPU cores between passes when running in parallel mode
- Track CPU core/thread ID of detected memory errors, and include the list of CPUs in error in test summary/report
- Added tracking and reporting of min/max/average CPU + DIMM temperatures (when supported by DIMM)
- Added SMBIOS memory device info to reports
- Modified DRAM address ECC error reporting from (Column,Row,Rank,Bank) -> (Channel,Slot,Rank,Bank,Row,Column)
