In Search of True DDR2 Bleeding Edge Memory

Crucial/Micron DDR2-667 (Ballistix) Is Geared For Overclocking

Out of all 16 test candidates, this RAM impressed us most with its overclocking capabilities. They were in fifth place with DDR2-968 (484 MHz). This is pretty remarkable. It's also rare to find DDR2 RAM that can operate at CL3.0 timing levels at standard input voltage levels (1.8 v). But their cryptic labels earned our ire - what was the vendor trying to communicate to buyers here?
