techPowerUp posted a review on the A-DATA X-Series DDR3 1600 MHz CL7 2GB Kit

The A-DATA X-Series is available in DDR2 and DDR3 flavors. Their DDR3 1600 MHz is set at a solid CL7 and comes with graphite colored heatspreaders in a very elaborate package. If 1600 MHz is not enough, you may go for the 1900 MHz version instead.
