What makes this memory stand out in the crowd is its awesome price which is pretty much the best price you can find for a brand-name DDR2 memory.
For this price you get a rock stable memory kit which offers a lot of overclocking headroom. Actually so much that I don't see a reason why you would want to buy more expensive memory. The difference between running upward dividers and 1:1 is about 2-3% depending on the application.
Being able to go from the advertised DDR2-4200 to DDR2-5800 is really impressive. Even if you are an overclocker and increase the CPU's FSB there's plenty of headroom, even at the 3:4 memory ratio.
