Corsair CM2X1024-6400PRO & CM2X512A-5400UL - Page 6

Do note that all the SANDRA benchmarks are synthetic and thus may not tally with real-life performance. The latter stands for whatever your environment is, i.e. which applications you run with what amount of data and so on. It is up to you to decide whether what Sandra measures is what you want to measure.

Below you can find the scores of Sandra starting with memory performance:

It will be quite difficult to understand what we present to you today. Interpreting data in the way we tested and what we can show you simply is hard to comprehend, especially with all the mathematic BIOS stuff timings and dividers. Memory tweaking and overclocking is close to science. Let me try to explain a little how to interpret the chart.

When you look at for example the first three XMS2-5400 results then we can tell you that our CPU at all times was running at 3600 MHz. The last XMS2-5400 results where it says 285 FSB x14 is a full system overclock. That's throughout our benchmark session you'll notice the maximum overall performance gain as not only the memory runs faster, the CPU is also clock higher (~4 GHz).

The same goes for the XMS2-6400 Pro scores, we tested in a similar way.

First of at that FSB our mainboard was at the very peak of it' capability. The clock generators started having a hard time and there were tiny variances with every score we took. What we did was we each ran the test five times and presented you the average. We are hitting a number over 8000 MB/sec. How on this earth is that possible? DDR2 can run asynchronously from the system bus, which means that it does not need to run at the frontside bus speed. In fact thanks to the ABIT mainboard we strapped the Nortbridge, it can run to 1066 MHz, which allows us to give the memory a 3:4 ratio of the FSB, which means that on a system running a standard 200MHz FSB the memory in fact would run at 267Mhz, or the standard PC2-4200 533 MHz DDR2 speed.
