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
