OCZ's Platinum line of ram is primarily aimed at hardcore overclockers and their PC4200 is no exception. With a default bus speed of 200 MHz, today's AMD systems require their buses overclocked by at least 33% to even reach the advertised speeds of the ram. The advantage to buying such high speed ram is that when overclocking you are eliminating one more component that can hold you back from maximizing your systems speed.
