Version 5.0 release for UEFI 3/Dec/2013

• Completely re-written to work under UEFI.
• Native 64-bit support
• No longer requires the use of the PAE workaround to access more than 4GB of memory. (PAE = Physical Address Extension)
• Mouse support, where supported by the underlying UEFI system. On older systems a keyboard is still required.
• Improved USB keyboard support. The keyboard now works on systems that fail to emulate IO Port 64/60 correctly. So Mac USB keyboards are now supported.
• Improved multi-threading support, where supported by the underlying UEFI system.
• Dual boot with Memtest version 4 for supporting older systems without UEFI. So with a single USB or CD drive both UEFI systems and BIOS systems can be supported.
• Reporting of detailed RAM SPD information. Timings, clock speeds, vendor names and much more.
• Support to writing to the USB drive that Memtest is running from for logging and report generation. In all prior MemTest releases there was no disk support.
• Use of GPT. (GUID Partition Table)
• ECC RAM support (limited hardware support, ongoing development)
  • Detection of ECC support in both the RAM and memory controller
  • Polling for ECC errors
  • Injection of ECC errors for test purposes. (limited hardware only)
• Option to disable CPU caching for all tests
• Support for reading parameters from a configuration file to allow settings to be predefined without the need for keyboard input. This can help with automation.
• Support for Secure Boot
• Speed improvements of between 10% and 30%+. Especially for tests, #5, #8 & #9. This is the result more moving to native 64bit code, removing the PAE paging hack, switching compilers and using faster random number generation algorithms.
• Addition of 2 new memory tests to take advantage of 64bit data and SIMD instructions.
