Description

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

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

• Sequential 128 KiB block read/write tests with Threads=1, 2, 4, 8, 16, 32, or 64
• Random sequence 4 KiB 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
• 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

Perfect!

I've been looking for an app to test RAM speed and I have found it! Works perfectly and does what I need.
