New Features
Support for DDR4 RAM (and associated hardware), including retrieval and reporting of DDR4-specific SPD details
Support for Haswell-E (DDR4) ECC detection (untested)
New RAM benchmarking feature allowing results to be graphed and saved to disk. Previous results can be graphed on the same chart for comparison.
New "Hammer Test" for detecting disturbance errors, which in simple terms, is caused by repeatedly accessing addresses in the same memory bank but different rows in a short period of time. For more details, see this paper by Yoongu Kim
Fixes/Enhancements
Fixed ECC detection for Ivy Bridge-EX/Haswell-EX chipsets that have a 2nd memory controller
Fixed ECC errors immediately being reported after starting test (Ivy Bridge-E)
Updated ImageUSB to v1.1.1015 which includes an option to zero the USB drive
Running memory tests in parallel mode is now more robust for UEFI BIOS that exhibit inconsistent multiprocessor behaviour
Fixed detection of the number of enabled processors for UEFI BIOS that exhibit inconsistent multiprocessor behaviour
Fixed test status screen not being displayed correctly for consoles with small/large screen widths
Increased maximum # of supported CPUs to 72
Increased maximum # of supported RAM modules to 64
In the RAM SPD menu screen, PGUP/PGDN can be used to navigate between pages of RAM modules
For specific cases where files under EFI\BOOT cannot be accessed (eg. grub2), log/report files shall be written to the root directory
During MemTest86 boot-up, the system memory map is now written to log file
CPU speed measurement is now more robust by taking multiple samples
Various optimizations of the size of the MemTest86 binary
Forced a memory address limit of 32-bits when running under 32-bit UEFI
Memory ranges to be tested are now allocated at the beginning of each test (due to the possibility that the memory map changes in the middle of testing)
Reduced the number of log messages written when waiting for other processors to finish when running in parallel mode
When allocating memory for Bit Fade Test, leave 1MB of free memory available (to prevent firmware drivers from running out of memory)
