Memtest86 5.0 | 10.27 Mb
MemTest86 is a free, thorough, stand alone memory test for computers. BIOS-based memory tests are a quick, cursory check and often miss many of the failures that are detected by Memtest86.
Change in 5.0
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.
Includes changes from the previous Beta version
