"Eventually DDR3 memory will take over the memory market but it will still take a while before DDR3 memory adoption will rise - the price will have to go down first. One of the memory series you might want to consider if you're going to buy a high-performance memory kit today is OCZ's Flex XLC. In this review I'm taking a look at the 800MHz version which runs at CL3 timings. The DDR2 FlexXLC memory series from OCZ is designed for watercooled systems and features four products: 800MHz memory with 4-4-4-15 timings, 800MHz with 3-4-4-15 timings, 1150MHz with 5-5-5-18 timings and 1200MHz with 5-5-5-18 timings."
