Kingston HyperX 2GB DDR3-1800 Dual Channel Memory Kit Review
 

The kit in question features two 1GB sticks of PC3-14400 (1800MHz) DDR3 memory rated for 8-8-8-24 timings at 1.9V. While slower kits showed that they could be overclocked to perform nearly as well as this Kingston HyperX 2GB DDR3-1800 dual channel memory kit, if you are looking for plug and play performance at 1800MHz (and above), this kit is worth considering.
