Genres: Utilities, Education

AmorphousMemoryMark measures memory module read/write performance in GB/s.

• Sequential 1 MiB block read/write tests with Threads=1, 2, 4, 8, 16, 32, or 64
• Sequential 1 MiB block read/write tests
• Random sequence 4 KiB block read/write tests with Threads=1, 2, 4, 8, 16, 32, or 64
• Random sequence 4 KiB block read/write tests
• Read/write GB/s scores using memmove()/bzero() functions, "rep movsb/stosb" instructions (Intel only), temporal load/store instructions, and non-temporal load/store instructions.
• Test data: random or zero (Only applies to read tests. Write tests will always use zeros)
• Test size: 128 MiB, 256 MiB, 512 MiB, 1 GiB, 2 GiB, 4 GiB, 8 GiB, 16 GiB, 32 GiB, or 64 GiB
• Test interval: 0 seconds, ..., 10 seconds

A permission was given by the author of CrystalDiskMark to use an identical or similar user interface in this app.

Release notes:
• Changed the multi-threaded sequential read/write measurements to use 1 MiB block size instead of 128 KiB block size.
• Changed the measurement order to match AmorphousDiskMark. SEQ1M/T8, SEQ1M/T1, RND4K/T8, and RND4K/T1.
• Added space for an extra digit in order to accommodate up to 9,999.99 GB/s measurement results.
