Exceleram DDR3 PC3-12800 1600MHz 4GB Memory Review

Everest – Memory Copy

This benchmark measures the maximum achiveable memory copy speed. The code behind this benchmark method is written in Assembly and it is extremely optimized for every popular AMD and Intel processor core variants by utilizing the appropriate x86, MMX, 3DNow!, SSE, SSE2 or SSE4.1 instruction set extension. The benchmark copies a 8 MB sized, 1 MB aligned data buffer into another 8 MB sized, 1 MB aligned data buffer through the CPU. Memory is copied in forward direction, continuously without breaks.

In order to avoid concurrent threads competing over system memory bandwidth, Memory Copy benchmark utilizes only one processor core and one thread.

The memory copy tests gave just under a 400MB/s difference between this kit and the rival Kingston, but it is worth noting that the Kingston kit was comprised of 8GB and as such is quite suprising results from the Exceleram.

Overclocked Results:

The overclock on the memory copy tests gave a clear 600MB/s increase over stock which would put it just behind the Patriot Viper 6GB triple channel kit we reviewed quite some time ago. An increase like this from such a small overclock gives a lot of hope for voltage increasing to push out more MHz.
