Testing (continued):
The first test to evaluate is Lavalys Everest Ultimate Edition 4.20. Four sets of results are provided which gauge performance in terms of memory read speed (in MB/s), memory write speed (in MB/s), memory copy speed (in MB/s), and memory latency (in ns). Higher values are better for memory read, write, and copy speeds, while lower values are desirable for latency.
The data above shows that the there is a pretty big difference between 800MHz and 1066MHz on the Aeneon kit, and surprisingly the Aeneon kit does much better than the Kingston kit at 800MHz despite comparable timings. Overclocking to 1111MHz provides a big performance boost, and checking some of my older reviews shows that these results are better than some 2GB DDR3 kits running at much higher frequencies.
PassMark Performance Test v6.1 offers a whole suite of benchmarks which can analyze the performance of most of your systems components. Even if you focus on memory alone you can get seven different results to compare. I chose to report their composite "Memory Mark" value as an overall indication of the performance. Higher numbers are better for this unitless value.
The improvements with higher clock speeds are more subtle in this test, but at 800MHz the Aeneon kit beats the Kingston kit, and things just progress upward from there.
