Two years have passed since Intel first introduced chipsets that use DDR2 memory. The fast available memory in those days was DDR2-533, operating at a speed of 533MHz (266 MHz DDR). Because of the higher latencies of DDR2 there was no noticeable speed advantage to the then widely used DDR 400. In the two years since introduction of DDR2 memory a lot has changed: the technology has improved substantially, and now both Intel’s 965/975 and AMD AM2 systems support the DDR2-800 standard. Some memory manufacturers even go a few steps beyond that, and produce memory suitable to run at speeds over 1000MHz.
