Another OCZ review for you!
Quote: The memory performed beautifully at very aggressive 2-2-2-5 timings and we pushed memory bandwidth towards ~5100 MB/sec on a (normally) 800 MHz FSB Pentium 4 processor which really needs memory bandwidth. It would have gone much further with a higher Voltage. This product uses Winbond BH chips. The nature of these chips is such that they do very firm 2-2-2 timings at 200mhz with 2.8v, yet for a good overclock at 2-2-2 timings, they generally require 3.4v to 3.5v
