In Search of True DDR2 Bleeding Edge Memory

G.Skill's DDR2-675 Confusing Label

The G.Skill memory module label is downright unconventional: The PC2-5400 designation suggests that the module runs at DDR2-675. In reality, however, it's just another 667 module. To operate at the fast CL3.0 mode, it was necessary to boost input voltage all the way to 2.2 v. The competition does it better.
